Advantage of Manufacturing 2 layer PCB

Advantage of Manufacturing 2 layer PCB

If you have read our article about 1 layer PCB,you may know the 1 layer use area very small.
But this is not ture for 2 layer PCB.
Double sided pcbs, common in both production and prototype circuits, allow a higher density in components and make layering of tracks an easier process.

2 layer PCB manufacturing process is very easy

Compared to multilayer pcbs, double layer pcbs do not need lamination, but need plating in order to reach through hole function.So the 2 layer PCB manufacturing process step become very easy.

PCB manufacturing detail process introduce

Double sided printed circuit boards are made with a substrate of non-conductive material, over which a layer of copper is placed on top and the bottom of it, and in the case of double sided boards, the copper is also layered on the bottom side of the substrate.

Two kind PCB hole types of 2 layer PCB manufacturer process

The circuits on top and bottom layers are connected by a “bridges” called the guide hole (via), which is also called plated through hole (PTH), and the hole without connecting function is called NPTH holes because there is no metal in hole.
