Product description

The difference between a double-sided PCB and a single-sided PCB is that the single-sided circuit is only on one side of the PCB, while the double-sided PCB can be on both sides of the PCB. Lines are connected. Parameters of double-sided PCB board In addition to the different production process of double-sided PCB board production and single-sided PCB board, there is an additional copper sinking process, that is, the process of conducting double-sided circuits.

1. The single-sided printed circuit board is usually a single-sided copper-clad laminate. The etched circuit pattern is made on the copper surface by screen printing or photoimaging, and the excess copper foil is removed by chemical etching to form a conductor pattern. .

2. The double-sided printed circuit board has upper and lower conductor patterns, and the upper and lower vias are connected by expensive perforations. In the processing of printed circuit boards, the hole walls of expensive perforations are plated with copper layers to make the upper and lower layers conduct. Double-sided printed circuit boards are usually made of double-sided copper-clad laminates. A resist pattern is made on the copper surface, and the excess copper foil is removed by chemical etching to form a conductor pattern.

Double-sided PCB and single-sided PCB can be basically distinguished from the appearance. Single-sided is a circuit board with only one layer and a line layer. Double-sided PCB is a circuit board with two wiring layers with via holes in the middle, so this is a single-sided circuit board. The difference between double panels.
