FR4 OSP Surface Multilayer Printed Circuit Board 4 Layer PCB Board OEM/ODM Service

FR4 OSP Surface Finishing Process

A Multilayer Printed Circuit Board (PCB) is a sophisticated assembly consisting of three or more conductive copper layers laminated together under high pressure and heat, with insulating materials (such as core and prepreg) separating each layer. Unlike single-sided boards, this complex structure enables high-density wiring and superior signal integrity.
