Why use Immersion Gold PCB Board?
Printed circuit boardssurface treatment,Anti-oxidation, tin spray, lead-free tin spray, immersion gold, immersion tin, immersion silver, hard gold plating, full board gold plating, gold finger, nickel palladium gold OSP.
PCB board design layout rate and design efficiency skills
The size and number of layers of the printed circuit boards need to be determined at the initial stage of the design.
Multilayer PCB board test technology
In complex multi-layer PCB board detection, two common methods are needle-bed test and double-probe or flying-needle test.
Factors Influencing the Appearance of PCB Board
With the rapid development of PCB board manufacturing technology, users are not only interested in the internal quality of PCB board, but customers also put forward higher requirements for the appearance of PCB board.
Reasons for poor coating of PCB circuit board
1. Pinhole of PCB circuit board. The pinhole is due to hydrogen adsorbed on the surface of the plated part and delayed-release. The plating solution cannot moisten the surface of the plated part.
Several technologies to improve the lamination quality of PCB
Laminating is an important process in the manufacture of PCB multilayers. The control of lamination quality is becoming more and more important in the manufacture of PCB multilayers.
