Shenzhen Honglijie has its own SMT chip factory, which can provide SMT chip processing services for the smallest package 0201 components. Next, I will introduce the precautions for the use of SMT processing patch adhesive.

Shenzhen Weisheng Electronic Technology Co., Ltd. is a PCBA processing manufacturer with its own SMT chip factory. The chip factory is equipped with 2 Yamaha fast chip assembly lines, 2 DIP plug-in production lines, and AOI optical detectors. The minimum package can be 0201 yuan Device SMT chip proc

In smt patch processing, soldering is an important link, which is related to the performance and appearance of the circuit board. In actual production and processing, poor soldering may occur due to some reasons, such as common solder joints. Not full, will directly affect the quality of smt patch p

Inspection and precautions before smt processing1. Inspection of smt components: The main inspection items of components include: solderability, pin coplanarity and usability, which should be sampled by the inspection department. To test the solderability of components, stainless steel tweezers can

Solder paste is an indispensable processing consumable for SMT chip processing. Next, Shenzhen SMT processing manufacturer-Shenzhen VIASION Electronic Technology Co., Ltd. will introduce solder paste from three aspects: the selection of solder paste, the correct use and storage of solder paste, and

When the line is less than 25 mm from the edge of the board, the line impedance value is 1~4 ohms smaller than the middle of the board, and the impedance value is less affected by the position when the line is more than 50 mm from the board edge. Next, it is recommended to preferentially select the

The copy board is also called the change board, which is the reverse technology research on the designed PCB board. With reference to a large amount of information, the process of copying boards is summarized as follows: The first step is to get a PCB. First, record the model, parameters, and positi

The positive film of the circuit board: generally the pattern process we are talking about, the liquid used is an alkaline etching positive film. If the negative film is used, the desired line or copper surface is black, and the part is transparent, and the same is true. After exposure by the line p

PCB design requires different grid settings at different stages. In the layout phase, large grid points can be used for device layout.For large devices such as ICs and non-positioning connectors, 50 to 100 mil grid precision can be used for layout. For passive small devices such as resistors, capaci

PCB copy board steps _ detailed full versionThe first step: preparationGet a good circuit board to see if there are components with high position. If you have the component number, component package, temperature value, etc., make detailed records. Scan as a backup before disassembling the component.
