Multilayer PCB is Printed Circuit Board with more than 2 layer. Multilayer PCB must have 3 conductive layers Interconnected with copper plated holes.
Multilayer PCB is a Printed Circuit Board with more than 2 layers. A Double-Sided PCB has two conductive layers on top and bottom of the PCB substrate. A Multilayer PCB must have a minimum of 3 conductive layers of conductive material or copper layer. All the layers are interconnected with copper plated holes. The layers can be 4, 6, 8…upto 40 layers.
A multilayer PCB is complex by design. The top and bottom layers look same as a double sided PCB but has staked layers on both sides of the core. All the layers are compressed to form a single Multilayer PCB where all the layers are interconnected via copper plated holes.
All the active and passive electronic components are assembled on top and bottom layers. All the inner stacked layers are meant for routing. Both through-hole electronic components and Surface Mount Components (SMD) can be soldered on either side of this type of PCB. SMD components can be soldered with Surface Mount Technology and other PCBA Tools. A general Multilayer Printed Circuit Board has following layer stacking:
Multilayer PCB manufacturing process needs special precaution as there are more chances of cross connections, overlaps, tracing in copper areas, etc. The whole process needs to be done in an ESD-Safe and Cleanroom environment. Special manufacturing setup and equipment are needed for 8+ layer PCB manufacturing process.
Following are the steps involved in Multilayer PCB Manufacturing Process:
Service value
Independent quotation system to quickly serve the market
PCB manufacturing
High-tech PCB and PCB assembly production line
Material purchasing
