PCB design is an integral part of any electronic product development project. PCB design uses a CAD software tool to create a 3D rendering of a PCB from a 2D schematic which is then used to manufacture the board. An optimized PCB design ensures the circuit board performs as desired and within the expected specification. PCB designers must follow a specific process that follows the steps of mechanical definition, critical placement, placement, critical routing, routing, final design rule checks, and creating outjobs.     • PCB Design Software Tools Many computer-aided design (CAD) software packages are available, some free and others requiring payment. Altium Designer, PADs, Allegro, and OrCAD, are the most commonly used PCB design software tools. For more simple designs and engineering students and hobbyists, free CAD tools such as Kicad and ExpressPCB. These tools are limited in handling more complex designs and have limited features in comparison.   Features and capabilities of PCB design software can vary quite a bit from tool to tool. An engineer or designer may often choose a particular tool because it has the necessary features other tools do not. The more basic PCB design tools provide much more basic functions and features. Software that companies must pay for offers more features and abilities, such as complex routing with design rules specified and routing signal simulation.   As PCBs become increasingly more complex and often on a much smaller footprint, paid-for software packages are often preferred, if not required.   • Schematic Capture One of the first steps in electronic product development is the creation of a design specification. This document describes the board's requirements and identifies critical components, signal speeds, differential pairs, etc.   Once the specification is complete, schematic capture can begin. PCB schematics used to be drawn by hand and sometimes still are, but most schematics are drawn or "captured" using CAD software.   A PCB schematic is a two-dimensional drawing that shows which components connect to other components and provides instructions on how to layout the traces on the board. Using CAD software, schematic symbols are created by the engineer for each component, which is then linked to a PCB footprint or land pattern. The footprints are created by the PCB Designer and define each component's physical dimensions, pin locations, and if it is SMT or thru-hole.     • Component Placement PCB design is taking the two-dimensional schematics and creating a three-dimensional rendering. Once the schematic is complete and mechanical specifications such as board size and shape, constraints, and drill information have been set, component placement is the first step in the PCB design process. PCB footprints must have all of the required information input before they can be placed in the design; they must have all of the relevant information defined   Before delving too deep into component placement, it is essential to roughly place components, often in related groups, to get an idea of where they will be located and whether or not they will all fit on the board. It is essential to consider how different components will communicate and the speed with which signals need to maintain. A rough placement exercise can also help determine how many layers will be required to obtain a stackup. Next comes critical routing, meaning traces with very tight constraints that the PCB designer will not move later. Once the critical routes are locked down, a more general placement is done. The final placement must be thoroughly reviewed because placement changes after routing has begun can result in having to rip up and redo work.   • Routing Routing is connecting the components with traces as directed by the schematic. For complex designs with many constraints and requirements, some software tools allow the designer to input a set of design rules. If a rule is broken, it will be flagged during a design rule check. Then a netlist, a text-based file, is generated from the schematic. The netlist contains information such as reference designators and pin numbers. It also shows which components need to connect to other components.   The first step of routing is to lay down the critical routes. These are routes where signals must travel at a particular speed, make the connection within a required time constraint, or differential pairs. These will be locked down when complete. Critical routes are completed first, where the size and length of the trace are crucial. The rest of the routes are then laid down, usually in the order of difficulty or complexity. These traces often move up and down through layers through different types of vias. The PCB designer must do a final detailed review, and all DRC violations are either fixed or cleared.   • Manufacturing Outputs Once the PCB design process is complete and approved, the data for manufacturing are generated. The Gerber files are images used to show the different layers and will be used with a photo plotter for fabrication. Other files needed for fabrication are silkscreen, soldermask, and NC drill and routing.   For assembly, a whole other set of files is used to program the various machines involved in the process. These include a bill of materials (BOM), so the components can be sourced and purchased, a pick-and-place file used to program the pick-and-place machine, and the netlist for functional testing and inspection.

Printed circuit boards are internal components that send electrical signals to electronic devices. Each time you switch on your computer or click an icon on a cellphone, radio alarm, and stereo device, you're communicating with the printed circuit boards, found in the enclosures of these devices. When electricity serves as the bloodstream of electronics printed circuit boards serve as essential internal organs. In the current world of devices that are heavily dependent many people aren't aware of the intricate circuitry that is contained inside every smartphone or the portable player for MP3. In the absence of printed circuit boards the modern technology of today would never become feasible.   WHAT ARE PRINTED CIRCUIT BOARDS? PCBs are printed circuit boards. (PCB) is a type of substrate that has electrical components that are etched on. PCBs are available in single, double-layer, and multi-layer designs with copper layers that are corresponding. The most dense PCBs comprise several layers. They are made up of plated holes that connect conductors from various layers. On more sophisticated PCBs the substrate may be covered with resistors, capacitors as well as other parts. The layers of the majority of firm PCBs typically consist of the substrate made of glass epoxy FR-4. PCBs are a part of virtually all electronic devices, except the most basic of devices. Designing a PC requires intricate circuit details, however the assembly and manufacturing of PCBs are easily carried out. Because PCBs are wired, mounted components that are just one piece making them mass-produced, production of PCBs is an easy affordable and usually free of errors, particularly when contrasted with other wiring options such as point- to point and wire wrap. The PCB acronym can be applied to board assemblies and bare boards. If a piece of equipment has copper connectionsbut does not have embedded parts, the most appropriate title is printed wiring board, even though the term is virtually gone of the word "printed wiring board" from modern terminology. Other more popular terms are the printed circuit board as well as printed circuit assembly. It is a PCB containing electronic components.   WHERE ARE PRINTED CIRCUIT BOARDS USED? PCBs are a must in an array of electronic devices and computer parts. PCBs in their current form are in use since the 1960s in the past, as they were used of cash registers, calculators as well as other basic devices with electrical circuits. Since the 70s, PCBs started showing up in electronic watches, as well as some of the first video games, as well as personal computers. In the 1980s, PCBs were found in alarm radios as well as video cassette recorders Atari games consoles laserdisc and CD players, and cordless phones. The 1990s saw the ever-increasingly advanced and miniaturized PCB was the reason for the widespread use of desktop computers as well as peripheral devices such as scanners and printers to the majority of Americans. The rapid development of electronic devices in the last decade has resulted in more compact and lighter PCBs, with larger capacities than boards of the past. Smartphones, for instance are now smaller and yet are able to withstand any damage. The same trend was observed over the course of 12 years of portable MP3 players. They have evolved from the heavy weight, bulky Archos players in the early 2000s, to the sleek, light iPod Nano models, which are in high demand with listeners traveling. The advancement of chip components that offer greater flexibility has led to the miniaturization of devices. Thanks to Micro ball grid arrays and smaller boards that companies are now able to create tiny computer-controlled devices, knowing that PCBs can be compact enough to fit in the enclosure in which they are placed. This is in contrast to older PCBs that were larger, and the dimensions of the board could dictate the dimensions of the device that was enclosed.    

The pebs that kingtech is talking about today is not the pebs that we produce, but an element below. What are PCBs? Polychlorinated Biphenyls (PCBs) are blends of as many as 209 distinct chemical compounds that are chlorinated (known by the name congeners). There aren't any known natural sources for PCBs. PCBs can be described as liquids that are oily or solids that are light yellow to colorless. PCBs may exist in the air as a liquid. PCBs are not known to have any taste or smell. A variety of commercial PCB blends are marketed to the U.S. by the trade name Aroclor.   PCBs are utilized as coolants and fluids in capacitors, transformers and other electrical equipment due to the fact that they aren't easily burned and they are excellent insulation. PCBs were made but banned in the U.S. in 1977 because of the evidence that suggests they accumulate in the environment and could create harmful health consequences. Products that were manufactured prior to 1977 that could contain PCBs include older fluorescent lighting fixtures as well as electrical appliances that have PCB capacitors as well as old microscope and hydraulic oil. How do PCBs behave after they are exposed to the elements? • PCBs travelled through the air as well as water and soil in the course of their creation or use and then removal. They may result from leaks or spills that happen in their transportation, as well as from fires or leaks in products that contain PCBs. • PCBs are still released into the environment by hazardous waste sites and illegal or uninformed treatment of waste from industrial processes as well as consumers' products. They can also leak from older electrical transformers that contain PCBs and even burning some substances in burning incinerators. • PCBs won't degrade easily in the atmosphere and can remain in place for lengthy period of time. PCBs are able to travel for long distances in the air, and they can be placed in locations far from the point where they were released. When in water, only a tiny quantity of PCBs might remain in solution, however, the majority of them remain in organic matter as well as bottom sediments. PCBs are also extremely bonded to soil. • PCBs are absorbed by fish and small organisms in the water. They are also absorbed by other animals that consume these animals as food. PCBs are found inside the fish as well as marine mammal, accumulating to levels that could be times greater than those found in the water. How can I be subjected to the PCBs? • Utilizing old fluorescent lighting fixtures as well as electrical appliances and devices like refrigerators and television sets, which were manufactured over 30 years ago. These products could release small quantities of PCBs in the atmosphere when they become hot in operation and may be a cause of skin irritation. • Consuming foods that are contaminated. The most significant food source for PCBs is fish. particularly fishing caught by sport fishermen from contaminated rivers, lakes, as well as parts from Puget Sound. To minimize the risk of exposure to contaminants found in fish, adhere to our advice on eating fish. PCBs can also be found in dairy and meat products. • Exposure to air pollution near dangerous waste sites and drinking wells that have been contaminated water. • At work, during repairs or maintenance PCB transformers. • Accidents, fires or spills caused by fluorescent lights, transformers and other electrical devices from the past. • Removal of PCB materials. What are the effects of PCBs influence my health? The most frequently observed health adverse effects of people who are exposed to large quantities of PCBs are skin problems like acne and rashes. Studies on exposed workers have observed changes in urine and blood that could be indicative of liver damage. PCB exposures to the general population aren't likely to cause any liver or skin effects. The majority of the studies that examined health impacts on the health effects of PCBs for the entire population looked at children of mothers who had been exposure to PCBs.   Animals who ate foods that contained massive quantities of PCBs for only a short time period experienced minor liver damage, and some even died. Animals who consumed smaller amounts of PCBs in their diets over a period of months or weeks experienced various types of health adverse effects, including acne-like skin conditions, anemia and stomach, liver and thyroid gland damage. Other side effects that result from PCBs in animals are changes to the body's immune system as well as behavioral changes and diminished reproduction. PCBs do not appear to cause birth defects. PCBs and Cancer A few studies by researchers indicate that PCBs were linked to certain types of cancer in humans, including cancer of the biliary tract and liver. Rats who ate foods that contained significant amounts of PCBs for two years, developed liver cancer. It is believed that the Department of Health and Human Services has concluded that PCBs can reasonably be expected to cause cancer. The EPA as well as the International Agency for Research on Cancer have found that PCBs may be carcinogenic for human beings. What is the impact of PCBs impact children? Females who had been exposed to large amounts of PCBs in their work environments or ate large quantities of fish that were contaminated by PCBs were born with babies who weighed just a bit less than those born to women who didn't have the same exposures. Children born to mothers who consumed PCB-contaminated fish had abnormal responses to test of the infant's behavior. Some of these issues like issues with motor skills, and the loss of short-term memory, were observed for many years. Studies have also suggested an immune system is affected in babies who were born to or nursed by mothers exposed to high amounts of PCBs. There is no evidence of birth defects causing structural defects due to exposure to PCBs nor of health consequences of PCBs in older children. The most likely route that infants are affected by PCBs is through breast milk. Transplacental transfer of PCBs was also mentioned. In the majority of cases breastfeeding, the benefits outweigh any risk of being exposed to PCBs in milk of mothers.   What can families do to reduce the risk of being exposed to PCBs? • Children and you could get exposed to PCBs through eating fish in contaminated areas. To enjoy benefits from the health benefits of eating fish and minimize your exposure to contaminants, make sure you follow our recommendations for eating fish. • Children are advised not to play with old electrical appliances, devices, and transformers because they could contain PCBs. • Children should not be playing in the dirt around hazardous waste sites as well as those areas that have an explosion in a transformer. Also, children should be prevented from eating dirt or placing dirty hands, toys or other objects into their mouths. They should clean their hands often. • If you're exposed PCBs at work you can take them home on your body, clothes or other tools. Shower and change your clothes before leaving for work and workplace clothes should be kept apart from other clothes , and cleaned in a separate manner. Do you have a test for medical purposes to confirm if my body has been exposed PCBs? Tests are available to determine the levels of PCBs in your body fat, blood and breast milk, but they aren't routinely administered. A majority of people are found to have low levels of PCBs within their bodies due to the fact that nearly everyone has been exposure to PCBs. Tests can reveal whether you have PCB levels are high that could indicate previous exposure to higher levels of PCBs However, it is not able to determine how long or when you were exposed to PCBs or whether you'll experience health adverse effects.
