- [Company News]Pcb manufacturer production requirements and precautions2019/09/18/ 10:12
- As we know that the size of the many modern electronic products chip components trend to be smaller. In addition to the increasingly small and delicate chip components, the requirements of high sensitivity components processing environment are becoming more and more demanding. Under this product trend, in addition to strengthening product process supervision and innovation and evolution, FASTPCBA also controls the environment of PCB manufacturer SMT processing workshop more strictly.

- [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]Flexible pcb solder paste printing2019/08/17/ 09:41
- Flexible pcb does not have any special requirements on the solder paste composition. The size and metal content of the solder ball are based on whether there is the fine pitch IC on the flexible pcb. However, the flexible pcb has high printing performance requirements for the solder paste, and the solder paste should have excellent properties. Superior thixotropy, solder paste should be able to print off the mold easily and firmly adhere to the surface of the flexible pcb, without the problem of poor mold release, clogging of the stencil, or collapse after printing.

- [Company News]Pcb manufacturer china design connector four key elements2019/08/15/ 14:38
- Generally, for pcb manufacturer china, solder does not provide high-quality mechanical support. The soldering strength of the plug-in solder itself is much strong than that of surface mounting. One is because the plug-in solder has a large cross-sectional area; the other is because the lead is inserted into the through-hole to provide mechanical support.

- [Company News]For prototype pcb assembly, what are the features of laser reflow soldering?2019/07/11/ 14:46
- Laser prototype pcb assembly reflow soldering is mainly used in military electronic equipment. It uses the high energy density of the laser for instantaneous micro welding, and concentrates the heat to the soldering site for local heating, which has little effect on the prototype pcb assembly component itself, PCB and adjacent components. It is also possible to perform multiple points simultaneous welding.

- [Company News]Why should there be a serpentine trace on the PCB?2019/07/09/ 16:54
- Any trace on the PCB will cause a time delay to the signal when passing through a high-frequency signal. The main function of the serpentine trace is to compensate for the lesser delays in the "same group of related" signal lines. Usuall...

- [Company News]Regarding the BGA capsulation, you must read this article2019/06/21/ 17:25
- As electronic products move toward miniaturization, portability, and high performance, higher requirements are placed on circuit assembly technology and I/O pin number. Chips volume are getting smaller and smaller and more and more pins which bring difficulties for production and repairing. In order to adapt to the rapid growth of the number of I / O, the new capsulation form - Ball Grid Array (BGA) was put into practical usage in the early 1990s.
