We have an application where we are soldering a PCB onto aluminium pins
which have been embedded in plastic. The pins are about 10mm long and 3
mm diameter with a shoulder that takes the diameter down to 0.9mm where
the pcb would be soldered.
Questions:
1) Do i have to treat the Al before soldering - some say that i should
electroplate it with silver, which sounds expensive for a consumer
product.
2) Is there lead-free solder for this?
3) Can we use normal solder mask on the board? or do we need also need
some special solder on the solder mask on the PCB?
4) Will the heat not just dissipate into the pin and melt the plastic
before we can get the solder wetting the aluminium?
Thanks,
Vahid.
