Soldering precautions for tact switches

1. Exposing the terminals to mechanical stress during the soldering process can compromise the switch's structural integrity and electrical performance.

2. Using through-hole PCBs or boards with thicknesses outside the recommended specifications may result in excessive thermal stress. Therefore, conducting pre-verification tests is strongly advised.

3. Before proceeding with a second soldering cycle, ensure the switch has cooled down to ambient temperature. Failure to do so may lead to switch deformation, terminal loosening or detachment, and deterioration of electrical characteristics.

4. It is essential to validate the samples under conditions that simulate actual mass production environments.

5. Do not clean the switches with solvents or other cleaning agents after the soldering process is complete.
