Double Layers Build-up Flexible Printed Board Flex PCB

• The main function is to provide the top part of each electrical connection. As electronic devices increasingly complex, requiring more and more parts, PCB top of the line and the parts are increasingly dense. Standard PCB looks like this. Bare board (on top no parts) is often called the "PCB Printed Wiring Board (PWB)." Not easy to bend the material made . Can be seen on the surface material is a copper fine line, the original copper foil covering the whole board, and in the manufacturing process was partially etched away, leaving to become part of a network of fine lines . These lines are referred to as wire (conductor pattern) or said wiring, and to provide a circuit-connecting parts on the PCB. Parts to be fixed on the PCB
