To measure the technological level of a circuit board manufacturer, the first thing that comes to mind is the number of layers of the production and processing circuit board. So the multi-layer circuit board is more strict in the process of production. The multi-layer circuit board needs to sink copper in the hole, so that … Continued
When designing flexible circuit boards, have you encountered troubles in choosing solder masks and overlays? The solder mask and the cover layer have the same basic insulation function. Do you know the difference between the solder mask and the cover layer? Can the solder mask and the cover layer be overlapped for insulation? Do you … Continued
Recently, many customers asked me, what does the flexible circuit board mold include? And why do we need to open the mold? How many types of molds are there for flexible circuit boards? How to choose a suitable mold for flexible circuit boards? Today, let us understand the flexible circuit board mold together. FPC molds … Continued
Assembling components on FPC flexible circuit boards is required, as the smart wearable industry becomes more and more popular, due to the limitation of assembly space, surface mounting of SMD on FPC has become one of the development trends of SMT technology. However, FPC is more difficult to assemble than PCB because it is not … Continued
Brief description:The birth and development of FPCB and PCB gave birth to a new product of soft and hard board. Therefore, the rigid-flex board is the flexible circuit board and the rigid circuit board. After pressing and other processes, they are combined according to the relevant process requirements to form a circuit board with FPC … Continued
FPC is called flexible printed pcb circuit board, which is a kind of printed pcb circuit board (PCB). It is an important electronic device interconnection component of electronic equipment. FPC has the incomparable advantages of other types of PCB because it can be bent , Light weight, etc., in recent years, it has been … Continued

Analysis of the concept and process requirements of PCB solder mask opening Solder mask layer concept: Solder mask layer refers to the part of the printed circuit board to be coated with green oil. In fact, this solder mask layer uses a negative output, so after the shape of the solder mask layer is mapped … Continued
Vias are an important knowledge point in PCB design. Especially for high-speed multilayer PCB design, the design of vias needs to attract the attention of engineers. Next, let’s understand the knowledge of vias in PCB design. Vias are generally divided into three categories: through holes, blind holes, and buried holes. Blind hole: refers to the … Continued
HDI’s circuit board requires only one micro-blind hole to fail, which is almost equal to the failure rate of 20000PPM. For HDI technology, everyone is working hard to study the process, technology, and yield improvement. The topic of discussing how HDI is really successful is rare. Xing Electronics, X Tong Computer, and X Hua Electronics … Continued
1.Through hole opening, when the electronic component is in wave soldering, spraying tin on the inner wall of the hole will increase the hole’s current capacity. 2.In the factory processing, if the copper sinking process is not completed, there will be some holes conducting Defective, tinned through-hole windows are opened, and it is sufficient to … Continued
