Double Layers Build-up Flexible Printed Board Flex PCB

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

Product Details

Fr4 Multilayer PCB Tg170 HDI PCB Circuit Board with High Quality

HDI PCBs are characterized by high-density attributes including laser microvias, fine lines and high performance thin materials. This increased density enables more functions per unit area. Higher technology HDI PCBs have multiple layers of copper filled stacked microvias (Advanced HDI PCBs) which creates a structure that enables even more complex interconnections. These very complex structures provide the necessary routing solutions for today's large pin-count chips utilized in mobile devices and other high technology products
