The pcb fabrication is prone to cause various problems in a humid environment, such as short circuit, circuit board signal open circuit, these failures are all. How to judge whether the pcb circuit board is wet? If the pcb circuit board is used in a humid environment, the air in this environment contains relatively large…
The PCBA Board Manufacturing Process Should Pay Attention to These Points: 1. BGA, chip capacitors, crystal oscillators and other stress-sensitive devices are easily damaged by machinery or high temperature. Therefore, PCB manufacturers believe that when designing or strengthening equipment, they should be placed on a PCB with higher hardness, or some methods should be used…
One thing that is very common in SMT chip processing is electronic components. So how to replace SMD components in the circuit board processing process? First, prepare a temperature-controlled electric soldering iron with a ground wire. The width of the soldering iron tip should be equal to the metal end surface of the chip assembly….
As we all know, as the fundamental part of electronics, printed circuit board(PCB) has influenced our daily life from aspects. Household appliances, computers, digital devices, medical electrical equipment, military science, almost all the electrical equipment cannot work without PCBs. After a PCB is ready, the electronic components and parts can be assembled on it, then…
We know that in high-speed PCB design, seemingly simple hole often bring great negative effects to circuit board design. Therefore, in the design, we should try our best to do the following: 1. Considering both cost and signal quality, choose a reasonable holes size. For example, for the 6-10 layer memory module PCB design, the…
Many newcomers who are just entering the industry have doubts about the color of PCB boards, and do not know what color PCB base are of high quality. In fact, PCB manufacturing mainly provides the interconnection between components, and its color has no direct relationship with performance and quality, and the difference in color does not…
