In recent years, low-cost PCB proofing has been a hot topic for discussion. So there are different opinions about not having to reduce the price to attract customers. From the superficial point of view, low-priced PCB proofing may not do much harm to enterprises, or even attract a large number of customers, with the help […]

First, look at the proofing requirements. Can PCBA processing manufacturers really meet: 1. Have a look at the products manufactured by PCBA manufacturers, whether they are high-grade, middle-grade or low-end, which industry they manufacture, and whether their own PCBA proofing requirements can be met by the manufacturers. Some precision processing PCBA processing, general proofing enterprises […]

I. Part of the output power control loop of the power board The key part of the output power board is the output power control circuit. In the case of layout, you should first know the characteristics of the power circuit of the part of the output power. The key parts of the output power […]

Flexible printed circuit board. The number of circuits in one FPC can exceed 100, but it only occupies the thickness of 0.2mm Although it is more expensive than flat cable, it is widely used in smart products with compact volume. Especially mobile phones, smart bracelets and other scenes. Today, the most important thing for everyone […]

“High-speed backplane and high-speed backplane connector” is mentioned in “The culprits in several high-speed PCB designs”. So how is the high-speed backplane designed? What are the design steps from beginning to end? What are the key points in each stage? The case analysis of the current period is summarized. High-speed backplane design process The detailed […]

1. Multi-layer circuit board Jafani bites copper This problem must be traced back to the copper electroplating process. It is found that if the examples of deep hole barrel plating and buried hole barrel plating with high thickness-diameter ratio can be shown that the copper thickness is more evenly distributed, this kind of Jafani’s copper […]

With the popularization of SMT technology, SMT chip processing factory has strict requirements on packaging methods, coplanarity of pins and solderability of components, which leads to differences between reliability, manufacturability and reliability inspection of components in SMT production assembly line, and it is SMT chip with the formulation and implementation of production planning. Problems that […]

In the manufacturing stage of SMT SMD factory, the processing technology of lead-free reflow oven has always been a very obvious problem in PCBA production and processing. In the process of SMT chip production, high-quality lead-free solder joints can be produced, which has irreplaceable active effect in the whole process of electronic processing. However, in […]

Many people identify the quality of PCB according to the color of PCB. In fact, the color of motherboard has little to do with the performance of PCB. PCB, it’s not that the taller you look, the better you use it. The color of PCB surface layer is actually the color of solder resist. The […]

PCBA solderless press-in connection technology, also known as press-in technology, consists of malleable deformable or rigid terminals embedded in two or more sides. A kind of “moderate press-in” connection produced by the matching of metallized holes of pcb boards, which produces close point contact between the terminal and the metallized holes, and realizes electrical connection […]
