Solder for electronic soldering applications

Solder is an indispensable tool for soldering. It consists of different metal alloys and is used to connect electronic components. The solder is melted by direct contact with a hot soldering tip or by hot air. It is then applied to the desired location to create a strong connection that conducts both electricity and heat.

 

Solder consists of different metals in various proportions, including tin, lead and zinc, sometimes copper or silver. The content and proportionate composition affect the melting point, conductivity, as well as protection against oxidation and corrosion.

How to choose the right solder for your application

When choosing the right solder, the area of application must play a decisive role. In general, the various available solder tins all have a different melting point. The solder must always have a lower melting point than the material to be processed, which must be considered when choosing solder.
In addition, the used flux is a relevant selection criterion. The flux is added to the tin so that it flows better and spreads well. It also reduces the surface tension of the solder and protects it from oxidation. Basically, a solder of high quality, i.e. with a high current and thermal conductivity, should always be selected.

 

Last but not least, attention should also be paid to the diameter. The smaller the diameter, the easier it is to dose the solder. Therefore, beginners should go for solder with a small diameter.
