Wave soldering profiles

Wired connection elements should be processed in accordance with the DIN EN 61760-1 standard. We have included

two recommendations for practical wave soldering profiles, with which Weidmüller PCB terminals and connectors are

qualified.

When choosing a suitable profile for your application, the following factors also need to be considered:

- PCB thickness

- Proportion of Cu in the layers

- Single/double-sided assembly

- Product range

- Heating and cooling rates

The single and double wave profiles each indicate the recommended operating range, including the maximum

soldering temperature of 260°C. In practice, the maximum soldering temperature is quite often well below the above

maximum profile.
