2. Component Placement
a. Reduce the mechanical stress to a minimum during and after placing of the unit in order not to damage the terminals and
protective coating.
b. Misplacement of components may cause solder bridges.
3. Soldering
a. Reflow soldering: Recommendation is shown in the following chart.
b. Wave soldering: Recommendation according to IEC standards.
c. Hand soldering: Don’t touch the protective coating of the part. Solder within 3 seconds when the temperature is over 280ºC.
