Conducting the Code of Electricity Through Insulators

Jan 26, 2020

Truly said that with great power comes great responsibility. When Edison invented electricity he would have never thought in his wildest dream that his invention would make the living impossible without it and non-renewable.

To avoid the wastage of voltage and protect human from the dangerous effects of electricity. They are coated around the conductors that flow the current and are good receptors.

For usage at high levels or power transmission and high voltage such as transformers and Aluminium Capacitors manufacturer use state- of-the art utilities and conform to regulatory standards.

Paying attention to minuscule details to prevent every possible occurrence of bad happenings through short-circuit or high voltage transmission.

Like insulators, conductors are of significant importance in power transmission. In simple language they offer compliance to electricity and let it flow freely. Scientists say that every conductor has some insulting properties and every insulator is some form of conductor but only conductors can carry the necessary voltage of current that can be utilized.

For instance conductors like Aluminium Capacitors Steel Reinforced or ACSR is made up of multi layered aluminum wires and offers high tensile strength for transmission and distribution cables. These ACSR are reinforced by steel core. The steel bolsters the strength of insulator. Even though, the insulator is light weight and ideal for high voltage transfers.

The best example of insulators are air break 11KV Isolators (Double Break). These are ideal to break the current of electricity flowing in homes through transformers. Thus, offering better protection and resistance.

Providing smooth supply of electricity to houses and industries is a challenge but ensuring safety and protection of millions while doing the same, is no child’s play. A high quality insulator manufacturer should be ISO 9001certified.

Given the hazards associated to electricity, the equipment must comply with quality standards as set by the government. At present, the Insulators manufacturing industry is evolving and marked by the right blend of quality, technology and innovation. Looking to the growing needs of countries, they are doing extra maneuvers to complement the existing needs while creating solutions for the future.

Choosing a Torch

Jan 26, 2020

Now when the evening begins to set in you are not going to be able to just reach over and flick on the light switch. You will need to have some form of portable lighting with you. There are many different forms of lighting you can take, each with its own benefits and disadvantages. The first step in choosing your lighting is to decide what you are going to need it for. Write yourself a list of requirements and then scroll down the page to see which item suits your needs.

Torches

Torches tend to be lightweight and durable making them ideal for walking to and from the toilet block at night and spotting guy ropes when walking across a busy field. They come in many different forms and the more you pay the more durable and powerful the torch is. Below I have selected a few torches I believe are good examples of what you can buy within a certain price range to meet certain requirements.

At the lower end of the price scale is the Uniross Compact Torch which retails on Amazon for £6.04 and acts as an affordable, compact torch that is extremely lightweight with reasonable durability. This kind of torch comes with rechargeable batteries that can be charged 500 times saving you money in the long run.

For a few more pounds you can invest in a really durable torch like the MAGLITE TORCH BLISTER 4D BLACK which I have included as it comes with the benefit of the excellent Maglite reputation. Retailing at £21.91 you do pay extra for durability but the Maglite range are made from ‘aircraft’ grade aluminium and are water and shock resistant. You do have to compensate with weight but it is a small price to pay for an excellent torch. I always keep a Maglite with me.

The Dynamo wind up led flashlight torch*Silver/Black retailing at £5.99 is an example of an emerging technology proving popular amongst campers; A wind-up torch requiring no additional batteries! If you are unfamiliar with wind-up torches then the basic principle is that you wind a dynamo for a few minutes, storing energy as you do, which then powers the torch for a few minutes. These torches are great because you can just leave them with your camping stuff and not have to worry about the batteries running out over long periods of time. They can also be more cost effective in the long term ; £5.99 is effectively the cost of two sets of batteries so within a year you will have recouped the costs I’d imagine! These torches can be just as durable as regular torches but again you pay extra for this durability.

The 16 LED ULTRA BRIGHT HEADLIGHT HEAD LIGHT TORCH retailing at £6.99 is a battery powered head torch and is excellent in situations where you want your hands free. This can be on night walks, when your outside re-setting guy ropes in the middle of a stormy night, or when you just want to read your book as the night draws in. I have deliberately selected an affordable version but as always if you want longer lasting, brighter, more durable versions you will pay more.

The key factors you need to be accessing are ‘Is it durable enough?’ , ‘Is it bright enough?’, ‘Does it last long enough?’ , ‘Is it cost-effective?’. By weighing up your requirements against the specification for Torches  will easily allow you to determine which is best for the job.

Buying Cable Ties Shouldn’t Be Hard

Jan 25, 2020

From the day they were invented, they were promising. However, they couldn’t be used in a wide range of fields as they weren’t as good as they are today. However, as more and more industries began using them, there appeared changes and finally we’ve got what we see today.

There are plenty of practical uses of Cable Ties and people even use them for weird applications such as arts and crafts. Therefore, you could safely say that almost every sector uses them in some form or another.

Tips for buying the right kind of cable ties

Before you go ahead and buy cable ties, you need to decide why you want them and where you’re going to use them. There are plenty of different kinds of cable ties manufactured for specific purposes. Are you going to be using them for garbage bags, transport, computer accessories or something else?

You could opt for the slightly expensive, but amazing self-locking stainless steel ties that are widely sued in various aircraft and even a few other engines. Tefzel ties could be used in radiation emitting environments too; however, for smaller applications there are tiny ties which can be used for tying up your garbage bags as well as securing your mobile cables.

Find websites that sell them

There are plenty of websites that deal with cable ties and a simple search would give you plenty of results. However, you need to make sure that the place you’re buying form produces high quality ties as they need to be temperature resistant, non-corrosive and most of all easy to handle and use.

Try getting samples

Many websites go an extra mile to offer you samples to help you decide what you need. However, you would need to pay the shipping charges in these cases. Also, if at all the ties are unusual; most websites have tutorials on how you need to use them.

Time of delivery

You’re also going to need to make sure that the companies that you buy from deliver the ties fast. Usually they could take up to a week to be delivered. But, it all depends on the courier services that they use and where you live.

Price

Price is one of the most important factors when it comes to buying Cable Tiess. Find out if they offer you discounts when you place bulk orders, because in most cases you’re going to need a lot of them – especially if you’re going to be using them in your business.

Type of Connectors Used in a Laptop

Jan 25, 2020

Industrial & Automation Circular Connectors are found in most electronic devices; laptops come packed with a variety of these components. A better understanding of the connector ports present in a laptop, can help increase efficiency and ease of use.

USB Connectors

Connecting a portable USB drive or an external hard disk via USB port is not a big deal anymore. Anyone with a laptop will be familiar with USB ports; however they might not be aware of different variants in the market like USB 1.0, USB 2.0 and USB 3.0. These are classified on the basis of speed performance and efficiency.

While USB 1.0 is the slowest, USB 3.0 can give you the highest data transfer speed. USB 1.0 and 2.0 are pretty much similar and easy to identify. They have a rectangular metal interface with four connection pins made of brass. USB 3.0 is a newer version and offers very high-speed; although they are similar in shape, they have nine connection pins. USB 1.0 and 2.0 can be swapped in place of the other, while USB 3.0 can only be used in devices specified for this connector type.

Audio Connector

Audio connectors are another common find in laptops. Previously, laptops featured a phono plug that offered mono sound. This got upgraded to dual phonos providing stereo sounds. These days,a single stereo jack with a microphone input is being used. These connectors are used for transmitting in and out audio signals and are easily identified with their small circular design.

HDMI Connectors

Latest laptop models come with the HDMI (High Definition Multimedia Interface) connector, which helps to connect to a modern High Definition TV for video transmissions. HDMI connectors have largely replaced VGA output used in older laptops for transmitting video signals to larger monitors or televisions. These HDMI connectors have two rows, one with nine pins and the other holding ten-pins, which count to a total of nineteen connections. On the other hand, the VGA connectors had three rows with five pin holes in each row in a rectangular shape with curved ends. The HDMI connectors offer improved video quality with more contact interfaces.

Network Connectors

Apart from these Industrial & Automation Circular Connectors,RJ45 connector is present for network connection. It comes with a square design and eight brass pins. The cable is held to the connector though a catch. These are generally used to connect the router box or the network cable directly to the laptop. Old laptops had a smaller version of this connector, which had just four pins. This was used to get an internet connection through a landline telephone.

Basics of Signal Amplifiers

Jan 25, 2020

The term ‘amplify’ stands for ‘make it stronger’. The strength of the signal is usually measured in terms of ‘amplitude’. Thus, an amplifier is a device which aids to strengthen a weak signal. An amplifier can be termed ideal if it has good fidelity, lousy efficiency and uses feedback property. There are different classes of amplifiers. They are class A, class AB and class C. There are also some special classes like G, H, D and T usually called as Digital amps. Let’s have a brief overview about them.

Op Amps uses one or more transistors that conduct electricity during both the cycles of the signal. These amplifiers have low distortion, but they are inefficient because they generate lot of heat. In order to overcome this problem class B amplifiers are used. They use one transistor to conduct electricity during positive cycles of the waveform and another transistor to conduct electricity during the negative cycles of the same. Most of the audio amplifiers used today are class B. Class B amplifiers used today works efficiently in such a way that it’s distortions cannot be detected by human ear.

The above two amplifier concepts were merged and Class A/B was created by making one transistor to conduct electricity when another is also conducting but, this created its own distortion. This caused an overlap between two signals called as ‘gumming’. This means that the signal would become larger when both the devices conduct. Another class of amplifier is Class D amplifiers and it is also referred as ‘Digital amplifiers’. In this case, either the transistors are switched on or off to represent positive and negative cycles. This may cause distortion since, both the transistors cannot be switched on or off at the same time. This sort of amplifiers are used in subwoofers.

Class T amplifiers are more refined switching amplifiers. It implies the concept of signal processing which automatically eliminates switching distortion. A normal power supply requires three times the output to drive an amplifier to maximize its RMS rating. To understand how an amplifier works you need to understand the basic types of amplification. They are Voltage amplifier, current amplifier and power amplifier. Of these the first two are basic types and the third one is the derived type. Voltage amplifier is the one that boosts the voltage of a signal. Current amplifier is one that strengthens the current of a signal. Power amplifier is a combination of these two which works accordingly. The following are the basic factors.

The first criteria is feedback in which the output is taken as input but 180 degrees out of phase. The second one is fidelity in which the output must be an exact replica of the input which may be amplified. The third one is efficiency in which for every watt of output you need to use at least two watts of DC power supply.

The quality of an amplifier can be characterized by a number of specifications. The first one is the gain of the amplifier. This is determined as the ratio of the input to the output and is usually measured in decibels. The next one is bandwidth which may be defined as the difference between the lower and upper half power points. So, it is usually called as – 3 db bandwidth.

Efficiency is the next factor. This is measured as how much power of the input is usefully applied to amplifier output. The efficiency of the amplifier limits the amount of the output that is usefully available. Linearity is the other factor which determines the quality of the amplifier. An ideal amplifier should be 100% linear but in real they are linear only up to certain limits.

Noise factor is the measure of how much noise is produced in the amplification process. Noise is an unavoidable and undesirable factor of the device. Noise factor is measured in terms ratio of input signal to the output signal. Slew rate is the maximum rate of change of output variable measured in terms of volts per second. Rise time of an amplifier is the time taken by the output to change from 10% to 90% of its final stage when driven by a single stage of input.

Then, regarding the kinds of amplifiers it is of various types. They are power amplifiers, vacuum tube amplifiers, transistor amplifiers, operational amplifier, fully differential amplifier, video amplifier, Op Amps, oscilloscope vertical amplifier, distributed amplifier, microwave amplifier and so on. Each varies from other based on its own characteristics and specifications.

About Rectifier Diodes & Schottky Diodes

Jan 24, 2020

Rectifier Diodes & Schottky Diodes come in many shapes and sizes. High-current diodes are often mounted on a heat-sink device to reduce their operating temperature. It is possible to place diodes in parallel to increase the current-carrying capacity, but the VI characteristics of both diodes must be closely matched to ensure that current divides evenly (although a small resistor can be placed in series with each diode to help equalize the currents). All diodes have some leakage current (current that gets through when a diode is reverse-biased).

This leakage current-better known as the reverse current (IR)-is very small, typically within the nano ampere range. Diodes also have a maximum allowable reverse voltage, peak reverse voltage (PRV), or peak inverse voltage (PIV), above which a large current will flow in the wrong direction. If the PIV is exceeded, the diode may get zapped and may become permanently damaged. The PIV for diodes varies from a few volts to as much as several thousand volts. One method for achieving an effectively higher PIV is to place diodes in series. Again, it is important that diodes are matched to ensure that the reverse voltage divides equally (although a small resistor placed in parallel with each diode can be used to equalize the reverse voltages).

Other things to consider about diodes include maximum forward current (IF), capacitance (formed across the pn junction), and reverse recovery time. Most diodes have a 1-prefix designation (e.g., 1N4003). The two ends of a diode are usually distinguished from each other by a mark. For glass-encapsulated diodes, the cathode is designated with a black band, whereas black-plastic encapsulated diodes use a white band. If no symbols are present (as seen with many power diodes), the cathode may be a bolt like piece. This piece is inserted through a heat-sink device (piece of metal with a hole) and is fastened down by a nut. A fiber or mica washer is used to isolate the cathode electrically from the metal heat sink, and a special silicone grease is placed between the washer and heat sink to enhance thermal conductivity.

A Rectifier Diodes & Schottky Diodes is a device that acts as a typical pn-junction diode when it comes to forward biasing, but it also has the ability to conduct in the reverse-biased direction when a specific breakdown voltage (VB) is reached. Zener diodes typically have breakdown voltages in the range of a few volts to a few hundred volts (although larger effective breakdown voltages can be reached by placing zener diodes in series).

Generate Faster PCB Assembly Turnarounds

Jan 24, 2020

For a small PCB Headers  prototyping business intent on serving some of the best-known and most respected tech brands on the planet, quick turnaround is more than a marketing gimmick – it’s a promise. PCB prototype assembly is by no means a simple activity, and small, time-consuming hang-ups can turn into lost orders and angry customers in an industry where 48-hour turnarounds are the norm.

In order to be able to reliably produce results on such short time frames, PCB assembly plants need to optimize nearly every aspect of their workflow for speed and consistency. At the heart of this need is an inherent conflict between maximizing the assets and resources you already own or adding additional assets and resources to your environment.

Essentially, what fast-turnaround PCB assemblers want to know is whether they should hire additional help and make more use of their machines, or buy newer, better machines that may let them make the most of their current staff.

Imperfectly Optimized PCB Planning Systems
Before jumping into the issue of whether manpower or machine power really generates fast turnarounds, we need to be sure that the PCB planning system itself is already performing optimally. As William Ho asserts, component placement is the bottleneck of any PCB assembly line.

Essentially, that bottleneck is made up of two parts – component sequencing and feeder arrangements. PCB manufacturers need to choose the optimal sequence of components and then assign them to the appropriate feeders

There are nearly infinite ways that PCB component sequencing and feeder arrangements can be approached. Finding the truly most efficient solution is simply not feasible in a business context – not, at least, with current computational technology, and certainly not within a two-day timeframe.

PCB assemblers on a tight deadline use genetic algorithms to determine near-optimal planning systems without getting lost on the way to the “perfect” solution. While this is not a problem that can be solved with today’s technology, it’s important to remember that no current PCB assembly process is perfectly efficient. This becomes an increasingly complicating factor for high-volume PCB prototype companies.

More Machines Means More Set Up Time
Knowing that any given PCB assembly process must be less than perfectly efficient, we can turn to time constraints on workflow processes.

SMT machines are not plug-and-play devices. Even efficient machines require changeovers of at least an hour – if you run eight to ten setups a week, that means that you’re losing an entire day in production time every week.

Changeover times can become a massive drag on production, especially when dealing with tight turnarounds. Time, once lost, cannot be recovered, and every second of time saved boosts revenue.

Since SMT machines can encounter nearly infinite production possibilities on a single run, and are often tasked with making multiple runs per day, any changeover time is downtime. A UIC shows in a simple set of graphs according to SMT machine revenue generating time, every second counts – an hour of downtime for a line that generates $10 million yearly costs $5000.

While there are always ways to improve the efficiency of a PCB assembly line, there is no way to account for $5000 in unnecessary losses. Considering that some SMT machines can take up to four hours to set up for a single run of a prototype PCB, making the most of each workday is by far the better option.

Moreover, installing additional production lines does not affect the productivity of each individual line. While it may appear to improve PCB assembly turnaround, adding more lines and workers may cost more than its worth if overall production volume doesn’t also increase. For this reason, keeping workers late or even hiring an extra shift is by far the better option.

Night Shifts Can Generate More Value
Maximizing the amount of time that each machine can run is the best way to ensure efficiency on short-turnaround PCB Headers assembly projects. Finding workers willing to put in overtime – or hiring an entire night shift – is one of the best ways to ensure that you consistently meet assembly deadlines and minimize downtime.

Achieving Flexible Power Management For Embedded Systems

Jan 24, 2020

Embedded designers today are facing more and more pressure to increase battery life and at the same time offer more features. One only needs to look at the rapid increase of functionality in mobile handhelds for verification. It has become clear that battery chemistries are not improving at the needed rate to fulfill these requirements. This places the pressure squarely on silicon vendors to deliver better performance at lower power. As if this dilemma wasn’t challenging enough, designers face strict time to market requirements posed by shrinking design cycles.

Moreover, green movements are requesting a reduction in battery waste, which translates to embedded systems that require fewer battery changes. There are also government regulations (Example: Energy Star) across the globe to reduce stand-by current in appliances. The next generation of Embedded Switch Mode Power Supplies (SMPS) is going to need extremely low active and sleep power consumption while simultaneously increasing the amount of flexibility and programmability needed to meet time-to-market requirements.

Apart from lower current consumption, there is also a need to lower system voltage. A few years ago, the standard for minimum operating voltage was 3.3V. Today, it is 1.8V. Charting this trend, it is realistic to extend this trend into the sub-volt range for tomorrow’s devices. This opens up the ability to build Psoc-based designs with a single AA battery (whose end of life voltage is around 0.9V). Although some Psoc-based designs can run at 1.8V today, quite often the analog performance degrades with such low voltages. For handheld battery powered designs that require good analog performance, systems that can run at below 1 volt voltage and still meet the analog performance requirements, offer the ability to move to a single AA battery. This translates to lower cost to the consumer and fewer batteries.

How to achieve sub-volt operation?
Sub-volt operation can be achieved when the embedded Psoc device has a boost converter built-in that is able to boost the input voltage (example: 0.9V input voltage) to a higher system level voltage (example: 3.3V). In this mode, it is important that the noise from the boost converter does not affect the performance of analog peripherals. Figure 1 shows the system level connections for an integrated boost converter that is a part of a Psoc 3 programmable system-on-chip from Cypress Semiconductor.

The Psoc 3 and Psoc 5 families are field-programmable embedded Psocs that have programmable digital blocks and configurable analog blocks. These devices are designed to offer flexibility and programmability to the user while consuming very low sleep and active current. The architectures also offer precise analog performance (16-bit to 20-bit precision). The families are supported by Psoc Creator software, an integrated development environment that can be used to rapidly develop designs from end to end – all the way from device selection, configuring/programming the digital and analog peripherals, configuring the power system, firmware development, debug and programming.

Having an integrated boost converter that can accept sub-volt input voltages has the following advantages:
1. Ability to run the system from a single AA battery.
2. Ability to provide a guaranteed minimum system voltage even with a varying supply voltage
3. Ability to use the boost output voltage to run other circuitry in the system that needs higher voltage. Example: LCD glass, Sensor circuits, etc

Wide-supply voltage range
Having a wide supply voltage range that spans from 1.8V (0.9V with boost enabled) to 5.5V provides maximum flexibility to the user due to the following reasons:
1. Can span standard battery voltage ranges for most common batteries through their end of life voltage as shown in table 1.
2. Compatible to legacy system voltages of 3.3V and 5V.
3. Upper end of 5.5V provides margin above 5V for rail-to-rail measurements of signals from legacy systems.

The wide external supply voltage, while maintaining a stable low core voltage for the silicon can be accomplished by providing built-in Low Dropout Regulators within the device. Moreover having separate internal regulators for digital and analog domains ensures that analog performance is not compromised due to noise from the digital power rails. Figure 2 shows the system level connections and internal regulators that accommodates a wide supply voltage range.

Independent power supply for I/O banks
To allow interfacing to other devices in the system that might have different system voltages, an Psoc needs to have separate I/O power rails that can be independently set to any voltage within a wide voltage range. An Psoc that has 4 I/O banks, with each I/O bank able to be driven with any voltage from 1.8V to 5V, provides seamless interfacing to other devices on the PCB

Flexible power modes
While there continues to be a myth that programmable systems are power hungry, well thought-out programmable Psocs can have world class power numbers that match stand-alone MCUs. Keeping the end customer’s application in mind, the power modes that are desirable

In Alternate Active mode, a selected fewer number of peripherals are active. This provides a reduced power active mode that can be entered from the regular Active mode. Upon exit from this mode, the system returns to regular Active mode. An example use case for this is a situation where an Embedded Switch Mode Power Supplies (SMPS) with a display continues to operate while the display alone is turned off. When the display needs to be turned off, the system will enter Alternate Active, where the peripherals needed for the display are turned off.

Sleep is a commonly used mode in battery powered embedded systems. This is an extremely low power mode, where all peripherals are in low power state, while a real-time clock can be maintained. This mode is also used for systems that need to be duty cycled between active and sleep constantly. An example use case is a temperature sensor that needs to update its reading every minute. The system wakes up every minute, takes the reading and goes back to sleep. This results in reduced average power.

Hibernate is the lowest power consumption mode of the device while memory contents and configuration can still be maintained. The ability to wake-up from an I/O source provides the ability for the user or another device in the system to wake the device up. Hibernate mode can also be used to eliminate a power switch in a handheld device (since the device can wakeup on any button press).

Conclusion
A programmable Psoc offers high levels of integration and at the same time provides the user the ability to build their own custom peripherals using a highly configurable and programmable system. Carefully designed programmable Psocs can offer world-class power management features that not only meet MCU power numbers but also offer a configurable power management system that can also deliver precise analog performance.
