The influence of low-temperature solder wire solder joint brightness and how to improve it?

Low-temperature tin wireWhen there is an error in the brightness of the solder joint, is it due to the instability of the tin content? JJY guides everyone to understand the cognition and answers at the tin wire level together.

Because20%The low tin content leads to the low temperature beneath itTin wireThere's no reason to look for, right28%When the solder joint does not light up, the following points should be analyzed:

If there is an error in the tin content, the brightness will be impaired, mainly manifested in the tin content being63%Below, the higher the tin content, the brighter it becomes instead. The stark contrast is that when the tin content is lower, the brightness of the solder joint becomes dimmer instead. However, under normal circumstances,5It is rather difficult to identify within a certain degree.

Secondly, the same amount of tin content, such as63%When there is a significant difference in the composition error of the residue, the brightness of the solder joint will also be impaired. Some chemical elements have a more obvious impact on the brightness of the solder joint, such as copper, bismuth, silver, arsenic, iron and other elements.

However, the brightness of the solder joints can also be affected by temperature. If the solder joints are to exhibit good gloss, the temperature must be sufficient; otherwise, it usually reduces the smoothness of the surface layer and leads to roughness and unevenness.

JJYIt has been proved through practice that take one20An electric soldering iron with watts and another one60The soldering iron for tiles, when soldered onto the same type of solder wire, has different brightness levels.
