Selective soldering: The precise solution for electronic assemblies

2024-03-15 Wiki, Company

Selective soldering is a highly specialized process in electronics production that aims to connect specific components on printed circuit boards precisely and reliably. In contrast to conventional wave soldering, in which the entire PCB is immersed in a solder wave, selective soldering only involves soldering at selected points on the PCB. This enables targeted and controlled soldering without affecting other components.

Why is selective soldering necessary?

Selective soldering replaces manual soldering of components on printed circuit boards and offers numerous advantages over conventional soldering processes. It is particularly necessary when SMD boards are fitted with components on both sides or THT parts are arranged in such a way that they cannot be soldered in any other way. In addition, selective soldering enables the soldering of sensitive components that must not be exposed to a wave soldering process due to their low thermal stability.

Advantages of selective soldering:

Different selective soldering solutions:

There are different variants of selective soldering, which are used depending on the requirements and conditions in production:


The selection of the appropriate selective soldering solution depends on various factors such as the assembly configuration, the components to be processed and the production requirements. Selective soldering technology is particularly economical when few components or few individual pins need to be soldered and takes up significantly less space compared to conventional wave soldering systems. As KRIWAN Industrie-Elektronik and with Birkholz Elektronische Geräte as part of KRIWAN Holding, we offer customized solutions and many years of experience in the field of wave and selective soldering to meet even the most demanding requirements of our customers.
