Double-sided PCB Sample

Double-sided PCB proofing, the most commonly used process. At the same time rosin process, OSP process, gold plating process, gold plating, silver plating these processes, in the double panel is also applicable.

Tin spray process: good appearance, the pad is silver, the pad is easy to tin, easy to weld, low price.

Sikkim process: Stable quality, usually used in the presence of Bundin IC.

The difference between double-sided PCB board and single-sided PCB board

The difference between double-sided PCB board and single-sided PCB board is that the single-panel circuit is only on one side of the PCB board, while the double-sided PCB circuit can be in the two sides of the PCB board, with holes in the middle to connect the double-sided PCB board circuit. Parameters of double-sided PCB board In addition to the production process of double-sided PCB board is different from that of single-sided PCB board, there is also a copper sinking process, that is, the process of double-sided circuit conduction.
