The principle of soldering is a process in which a solid solder wire is heated and melted by a heated soldering iron, and then flows into the metal to be soldered with the help of flux, and forms a firm solder joint after cooling. When the solder is a tin-lead alloy and the soldering surface is copper, the solder first wets the soldering surface. With the wetting phenomenon, the solder gradually diffuses into the metal copper, forming an adhesion layer on the contact surface of the solder and the metal copper, so that both Combine firmly.

Shenzhen Weisheng Electronic Technology Co., Ltd. has its own SMT chip processing plant, which can provide SMT chip processing services for 0201 components in the smallest package, and supports processing with supplied materials and OEM materials. The next is how to solve SMT processing. Missing printing, low tin defects?

Shenzhen VIASION Electronic Technology Co., Ltd. has its own SMT chip factory, which can provide SMT chip processing services for 0201 components in the smallest package, and supports various processing forms such as processing with supplied materials and OEM materials. Next, I will introduce to you what inspections need to be done before SMT patch processing?

PCBA processing tin penetration is mainly affected by factors such as material, wave soldering process, flux, manual soldering, etc., which can be adjusted and solved in the following ways

Why do PCB board making holes need to be plugged? Conductive holes are also known as via holes. In order to meet customer requirements, the circuit board via holes must be plugged. After a lot of practice, the traditional aluminum plug hole process is changed, and the circuit board surface solder mask and plug hole are completed with white mesh. Stable production and reliable quality.

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
