FR-4 HASL pcb manufacturing and assembly Multilayer PCB Assembly
Multilayer Pcb Assembly Introduction
A multi-layer circuit board assembly means a multi-layer circuit board with more than two layers, such as four layers, six layers, eight layers, and so on.
To increase circuit wiring, multi-layer PCB circuit boards use more single-sided or double-sided circuit boards.
Using a double-sided board as the inner layer, two single-sided boards as the outer layer, or two double-sided printed circuit boards as the inner layer and two single-sided printed circuit boards as the outer layer.
