- [Company News]PCB prototype Circuit Boards Poor Plating Causes Analysis2019/09/11/ 10:12
- Due to the adsorption of hydrogen on the surface of the plated part and not released that form pinhole on pcb prototype pcb. The plating solution cannot be lubricated on the surface of the plating devices, so that the plating layer cannot be electrolyzed. As the thickness of the coating around the hydrogen evolution point increases, the hydrogen evolution point forms a pinhole. It features as a shiny round hole and sometimes with an upward small tail. When the wetting agent is absent in the plating solution and the current density is high, pinholes are easily formed on pcb prototype circuit board.

- [Company News]PCB smt layout tips and considerations2019/09/04/ 14:17
- For hardware electronics designers, the PCB smt design is becoming more and more complex. Advanced package devices with increasingly dense pins are used, and the network density per unit area continues to increase, bring more pressure on the layout. At the same time, more engineers cannot meet the 100% coverage rate of the autorouter, and hope to be able to conduct electrical rules to constrain the wiring to meet the signal integrity requirements.

- [Company News]During pcb manufacturing, PCB board debugging method2019/09/02/ 11:41
- For the new PCB board that we just got back during pcb manufacturing, we must first observe whether there are any problems on the board, such as whether there are obvious cracks, short circuit or open circuit. If necessary, check if the resistance between the power supply and the ground is large enough.
