Multilayer Printed Circuit Board(PCB) Fabrication

♦ What's Multilayer PCB?

A ​​Multilayer PCB (Printed Circuit Board)​​ is a type of PCB that consists of three or more conductive copper layers laminated together with insulating material (substrate) to form a compact, high-density circuit board. These layers are interconnected through ​​vias​​ (plated holes) to establish electrical connections between them.

♦ ​​​​Key Features of Multilayer PCBs:​​

1. 1. ​​Multiple Layers:​​ Typically 4, 6, 8, or even up to 50+ layers in advanced applications.
   2. ​​High Density:​​ Allows complex circuitry in a smaller footprint.
   3. ​​Improved Performance:​​ Better signal integrity, reduced EMI (electromagnetic interference), and controlled impedance.
   4. ​​Power & Ground Planes:​​ Dedicated layers for power and ground improve stability and reduce noise.
   5. ​​Complex Applications:​​ Used in high-speed digital, RF, and high-power circuits.
