Care needs to be taken when reworking the PCB (repairing or modifying the PCB), after it is finished. Heating the solder for removal from the hole during the repair has potential to damage the joint connecting the annular rings around the hole-plating.
Wave soldering temperatures with lead free solder are critical. Tighter temperature settings are needed because the solder, being lead free, has a higher melting temperature; if the process temperature is incorrectly set, either the solder won’t bond properly, or the components and board may be damaged.
Mixed Component Assembly Soldering
When both SMT and pin-through-the-hole devices are used on the same assembly, several steps are needed for soldering:
