PCBs in China: Fitting The World In The Palm of Your Hand

Cellphones, radios, laptops… imagine a world without them. Many of us in today’s time wouldn’t probably be able to fathom life without these ever-present electronic items. Have you ever looked inside any one of your electonic items? Have you noticed an intricate and elaborate board where all the other components seem to be connected to? That’s a PCB. PCBs or Printed Circuit Boards play a crucial role in making your gadgets work.

What are PCBs?

A PCB is sometimes known as Printer Wiring Board (PWB). This is also sometimes referred to as an etched wiring board and these are used to support and connect electronic components on copper sheets or boards. A printed circuit board which is already mounted with electronic components and fully-functional is called a PCA or PCBA, printed circuit assembly or printed circuit board assembly, respectively.

PCBs are very affordable and are very reliable. However, more is required when it comes to efforts in lay-outing and designing compared with wire-wrapped or point-to-point constructed circuits but high-volume production makes PCBs cheaper.

How did PCBs come about?

An Austrian scientist who was working in England, Dr. Paul Eisler, is credited in history as the maker of the first PCB, the first patent of which was issued in 1903. He got the idea by thinking of a less-bulky replacement for the radio tube wiring.

The simplest form of PCB is the single-sided variety which had circuitry on only one side. This is still in use to this day but it was more popular during the 1950s and 60s. In the 1970s, double-sided boards became the standard in the electronics industry as top and bottom circuitry became possible to be electrically interconnected. Double-sided boards are used today in many electronic consumer products like personal computers, keyboards, transformers and just about any other electronic equipment we use, buy and find in our homes. Double-sided boards, however, are a little bit more expensive than their single-sided counterparts.

Later on, as more complex electronic components came out, the multi layer circuit boards which sandwiched together a number of circuitry layers became the more widely used variety beginning in the 1980s. Modern computers, aerospace equipment and telecommunications gear, among others, all use multi layer boards.

Many companies have ventured into the production of PCBs for supply to makers of many electronic items we now enjoy today. A number of these companies have settled in San Diego, California offering their services and products to big and small manufacturers, major corporations and even to universities, research centers and government agencies.

Most PCB manufacturers cater to a variety of client needs, offering design, fabrication, assembly and system level assembly services to suit a customer’s needs for prototype or moderate to volumous production.

As we look back on our history, the technology that has helped us with our daily lives has evolved from simple technologies to more elaborate technologies. PCBs are just one of them. More and more of the world’s most-used items have PCBs running them like our own bodies’ central nervous system.

PCBs may pave the way for yet smaller and smaller products. Be at the forefront of these developments and partner with a highly skilled PCB manufacturing companies in China which may just help you and your company make the world fit the palm of your hands.
