- [Company News]Prototype pcb manufacturing, how to control PCB and components before wave soldering?2019/11/02/ 11:30
- For printed circuit boards that have been placed for a long time, the surface is generally cleaned, which improves the solderability of prototype pcb manufacturing, reduces virtual soldering and bridging. For component leads that have a certain degree of oxidation on the surface, the surface oxide should be removed firstly.

- [Company News]PCB smt's overall requirements for printed circuit boards2019/09/16/ 10:47
- Surface Mount Printed Circuit Board (SMB) is very different from traditional printed circuit boards. The PCB SMT reflow process requires SMB to pass through a 230 ° C (lead-free up to 260 ° C) high temperature furnace. Therefore, the requirements of the PCB SMT substrate material are much higher than those of the conventional printed circuit board, and the requirements are mainly high temperature resistance and flatness. In addition, because SMB has the characteristics of high density and small aperture, the processing difficulty is much larger than that of traditional printed circuit boards.

- [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]SMT pcb circuit board applying three anti-paint effect and precautions2019/09/06/ 10:32
- Three anti-paint is a specially formulated coating used to protect smt pcb circuit boards and their associated equipment from the environment erosion. The three anti-paint has good resistance to high and low temperature; it forms a transparent protective film after curing, and has superior properties of insulation, anti-moisture, anti-leakage, anti-shock, anti-dust, anti-corrosion, anti-aging and corona resistance.

- [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.
