Printed circuit board features
Printed circuit boards are the base on which microelectronic components such as semiconductor chips and capacitors are mounted. They are used to connect electronic components through conductive tracks. Printed circuit boards typically consist of epoxy resins, fiberglass, copper, nickel, iron, aluminum,
Is there a STANDARD printed circuit board? How it is looks like?
There is no standard printed circuit board. Each printed circuit board has a unique function for a particular product and must be designed to perform that function in a dedicated location. PCB designers use computer-aided design systems with special software
