Oem Electronics Printed Circuit Boards Manufacturer Multilayer Pcb Circuits Board
Multilayer PCB or multilayer printed circuit boards is a circuit board composed of two or more conductive layers (copper layers). Multilayer PCB can be divided into Multilayer Rigid PCB, Multilayer Flexible PCB, Multilayer Rigid-flex PCB. The copper layer is pressed together by the resin layer (prepreg). Due to the complexity of the multilayer PCB manufacturing process, low yield and difficulty in rework, their prices are relatively higher than single-layer and double-sided PCBs.
FASTPCBA manufactures up to 48 layers of multi-layer PCB, accepting pure single material or mixed pressing materials: Fr4, Rogers, Polymide, metal core etc.

Benefits of Multilayer PCBs (compared to single or double-sided PCBs)
Higher assembly density
Smaller size (considerable savings on space)
Increased flexibility
Easier incorporation controlled impedance features.
EMI shielding through careful placement of power and ground layers.
Reduces the need for interconnection wiring harnesses (reduces overall weight)
