The circuit board manufacturer tells you why you can't touch the circuit board with your hands? In winter, the human body can release up to tens of thousands of volts of static electricity. At the end of the year, the project has reached the final stage. Don't directly touch the live motherboard w

Today, Shenzhen VIASION Electronic Technology Co., Ltd. will talk to you about the method of identifying the IC mark and pin sequence. Let’s take a look at it together. There are many ways for circuit board manufacturers to identify the IC mark and pin sequence. Now the common identification meth

For pcb high-frequency boards, four points need to be paid attention to when designing wiring, which will be discussed in detail below.

In PCBA production and processing, how can we effectively save processing costs without affecting product quality? Next, Shenzhen PCBA processing manufacturer-Shenzhen Weisheng Electronic Technology Co., Ltd. will introduce the factors that affect PCBA processing costs.

The circuit board industry has windows in many manufacturing processes. It is a professional term for this industry, mainly referring to solder mask opening: using film to open the window, the PAD that needs to be soldered or dissipated is exposed to the green Outside the oil layer, in order to meet

The blistering of the circuit board after reflow soldering refers to the blistering of the solder mask green oil on the circuit board. This phenomenon is that light green bubbles will appear around individual solder joints after reflow soldering on the printed circuit board with components pasted.

In the appearance quality control of circuit board solder mask, the color of solder mask is a more important control point. For a production board using the same type of solder mask ink, the board surface solder mask has obvious color difference, which is generally not accepted by customers. So wh

Types of circuit boards: There are three major categories: single-sided, double-sided, and multilayer circuit boards.

In the circuit board production process, the immersion gold and gold plating process are very common processes. Because these two processes solve the problem of the soldering process, the pads are difficult to flatten. As the society is strict with the function and size of electronic products As the

How long the circuit board is stored depends on the surface treatment. Gold and electroplated gold are the longest. They can be stored for two or three years under constant temperature and humidity conditions. Followed by tin spraying and oxidation resistance. Especially for anti-oxidation, it is be
