- [Company News]Solder Paste Collapse Cause Analysis2019/11/28/ 16:27
- Collapse is divided into cold collapse and hot collapse. Cold collapse refers to the collapse behavior that occurs at room temperature. After printing, the solder paste gradually diffuses under the surrounding environmental conditions, and the solder paste coating gradually changes from a well-shaped brick to a smooth dome shape.

- [Company News]Electronic circuit board manufacturng 5s management2019/11/02/ 11:44
- 5s management is the basis of on-site management. The 5s management originated in Japan and refers to the effective management of production factors such as personnel, machines, materials and methods at the production site. This is a unique management method for Japanese companies. Since Seiri, Seiton, Seiso, Seiketsu, and Shitsuke are the first letters of the Japanese alphabet, the first letter of the Roman alphabet is "S", so it is simply referred to as 5s.

- [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 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.

- FPC is also called flexible pcb. The PCBA assembly welding process of flexible pcb is very different from the assembly of rigid circuit board. Since the hardness of FPC board is not enough, it is soft. If you don't use special carrier board, you can't fix and transmit. Basic SMT processes such as printing, SMT, and furnace cannot be completed.
