Shenzhen Multilayer PCBs Double Sided Circuit Board Service


Multilayer PCB or multilayer printed circuit board 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.

FASTPCBA is an Experienced Multilayer PCB Manufacturer
FASTPCBA has been producing Multilayer PCBs for over 20 years, our skilled team members have the knowledge and experience to handle your multilayer PCB needs. we have solved all types of problems with multilayer PCBs from various industries.



What are Multilayer PCBs used for?
Multilayer PCBs are particularly useful in the aerospace industry because they take up little room and are lightweight. They can also be found in cell phone repeaters, heart monitors, x-ray equipment, fiber optic receptors, industrial controls, automotive industry, atomic accelerators, nuclear detection systems and space probes.
Multilayer PCBs are also utilized in applications where crosstalk levels—electric or magnetic disturbance affecting the signal of an adjacent circuit—must be minimized.
