What Are Multilayer Printed Circuit Boards?
A multilayer printed writing circuit board contains three or more copper conductive layers, and usually with plated through holes. If the multilayer circuit board is constructed of both flexible and rigid materials, it’s referred to as a rigid-flex circuit board. A rigid-flex circuit board is a 3D interconnect that can be bent and folded into almost any shape. Rigid-flex technology allows designers to replace multiple PCBs with interconnecting wires and/or cables into one single unit, offering improved performance and increased readability.
Rigid-flex circuit board technology reduces the need for bulky, heavy wire harness cables within an electronic system. It also saves installation time and part costs and results in a cleaner — and typically more compact — top level assembly.
