What should I do if there is a sharp and continuous welding when the solder wire is soldered?
2022-12-02
A problem that may be encountered in the wave soldering process (solder ball and tin tip phenomenon), why does it occur? In many cases, it is because there is moisture in the through hole of the PCB board. During soldering, the moisture is heated and turned into water vapor. The steam splashes the flux from the tin bath, which will produce irregular solder balls. Solder paste manufacturers explain how to deal with this situation?
Welding of thin-walled pipes with low-temperature welding electrodes
2022-12-02
In the welding of thin-walled tubes with low-temperature solder bars, argon arc welding is generally used as the base and the acid electrode is covered. When welding martensitic heat-resistant steel, pay full attention to the problem of arc crater cracks, and fill the arc crater with multiple "spot arc welding" methods. In the unfavorable situation where the cooling rate of the weld seam is large, the strength is increased, and the weld seam joint is prone to cracks, a solder bar with a lower strength than the base metal can be selected. For example, in the case of multi-layer welding of thick plates or normalizing treatment after welding, it is necessary to prevent the situation of excessively low strength.
Detailed explanation of laser welding and laser soldering process
2022-12-01
The process of laser welding 1. Welding of tin wire and block components. Laser welding can successfully realize the connection between tin wire and block components. The size of block components can be arbitrary, and attention should be paid to the geometric dimensions of tin wire components during welding; 2. Tin wire to wire welding. Including wire-to-wire butt welding, cross welding, parallel lap welding, T-shaped welding and other 4 process methods;
Types and development status of tin materials
2022-12-01
Soldering tin raw material, its tin materials can be divided into: tin foil, tin powder, tin particles (beads, balls), tin profiles (rods, plates, sheets, strips). Three allotropes of tin: white tin, gray tin, and brittle tin. 1. Tin foil Tin foil is mainly used in the fields of medicine, chemical industry, light industry, food, art supplies and handicraft production, such as advanced dry capacitors, decoration, decoration materials, microwave oven insulation, food and wine packaging, folk religious activities and the use of tin foil Flexible, not afraid of extrusion, anti-corrosion, waterproof characteristics, used for packaging barrel linings of flame retardants, floor adhesives, synthetic paints and other organic chemical raw materials, etc., and also used as preforms in special welding
