Information on the soldering process
The following soldering processes are possible:
● Selective soldering process
● Manual soldering
● Laser soldering
Recommended soldering parameters for selective soldering with liquid solder:
● Maximum soldering temperature: 285 °C
● Maximum soldering time per pin: 2 seconds
During each of the above-mentioned soldering processes, you must ensure that no liquid
solder gets on the plastic parts or parts of the enclosure.
Achievable quality of the soldering points: Class 2 according to IPC–A-610 F (electronic
products with higher demands).
