What affects the solder quality of automatic soldering machines?

焊锡质量的主要因素有三个,分别是焊锡材料锡线(锡丝)、助焊剂、焊接的温度。 There are three main factors that affect the solder quality of automatic soldering machines , which are solder wire (tin wire), flux, and soldering temperature. Their characteristics are:

1. Solder material: Solder material is made of a variety of alloys. Different alloy tin materials have different characteristics, which are mainly reflected in wettability, melting point, temperature, and mechanical properties after welding. The so-called mechanical properties refer to stress, thrust, and pull. . If the tin wire material is not good, it will cause the soldering iron to not eat tin and tin burst.

2. Flux: commonly known as rosin, natural rosin is a resin, which can be mixed with a variety of chemical elements. Common liquid, solid, paste. Divided into high activity, medium activity, low activity. Flux mainly plays the role of decomposing oxides in the soldering process, and wets the soldering surface, which promotes better completion of soldering. If the quality of the flux is not good, it will lead to high residue after soldering. The residue contains halogen ions, which will gradually cause problems such as reduced electrical insulation performance and short circuits.

3. Temperature: If the temperature is too high, the solder flux will not evaporate, the soldering flux inside the tin wire will be directly evaporated, and the life of the soldering iron tip will not be good, which will cause easy oxidation. If the temperature is too low, it will cause cold welding, virtual welding, and short circuit In general, the welding should not exceed 400 degrees, and the melting point of tin is between 180-240, which is mainly determined by the composition of the tin wire.

的焊锡质量度。 If you do not pay attention to the above three points, they will affect the solder quality of the automatic soldering machine . Welding, fake welding, etc.!
