Multilayer Immersion Gold PCB Fabrication with 2OZ Cooper

♦ What's Multilayer PCB?

A ​​Multilayer PCB (Printed Circuit Board)​​ is a type of circuit board that consists of ​​three or more conductive copper layers​​, laminated together with insulating (dielectric) material to form a single structure. These layers are interconnected through ​​vias​​ (plated holes), allowing complex circuitry in a compact space.

♦ ​​Key Features of Multilayer PCBs:​​

• • ​​Multiple Layers​​ (typically 4, 6, 8, up to 50+ in advanced designs).
  • ​​Stacked Construction​​: Layers are bonded under heat and pressure.
  • ​​Inner Layers​​: Used for power/ground planes or signal routing.
  • ​​Vias​​: Plated holes (through-hole, blind, or buried) connect different layers.
  • ​​High Density​​: Supports complex circuits in a small footprint.
