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.
