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.

♦ Comparison with Single/Double-Layer PCBs:

Feature	Single-Layer	Double-Layer	Multilayer
Layers	1 (Top)	2 (Top + Bottom)	3+ (Multiple inner layers)
Complexity	Low	Medium	High
Cost	Low	Moderate	Higher
Use Case	Simple circuits	Moderate complexity	High-speed, dense designs
