Best Answer

In electronics, printed circuit boards, or PCBs, are used to mechanically support and electrically connect electronic components using conductive pathways, or traces, etched from copper sheets laminated onto a non-conductive substrate. Alternative names are printed wiring board or PWB or etched wiring board. After populating the board with electronic components, a printed circuit assembly (PCA) is formed. PCBs are rugged, inexpensive, and can be highly reliable. They require much more layout effort and higher initial cost than either wire-wrapped or point-to-point constructed circuits, but are much cheaper, faster, and consistent in high volume production. In chemistry and environmental protection, PCB stands for "polychlorinated biphenyl." This class of chemical was widely used as electrical Transformers because it will not burn. It was also used as a plasticiser in caulks and palstic materials. Only very limited uses of PSBs are now permitted in the United States and areas that have been contaminated with PCBs through leaks or less stringent disposal practices of the past oftenrequire extensive cleanup.

How do you make PCB?

Printed circuit boards (PCBs) are designed using Electronics Design Automation (EDA) tools and then fabricated in PCB manufacturing factories. PCB design involves both front end design (design, schematics entry) and backend (PCB layout/artwork design). The final design files are then released to PCB fabrication for manufacturing the bare boards. Electronic compoments can then assembled on these boards to achieve designed circuits.
