Can lead free and non lead free production mix in the same mach

Can lead free and non lead free production mix in the same mach | 26 April, 2006

Hi We are in the process of developing a lead free product to be used in a non lead free selective soldering machine, i do have concern in these, and hope you guy can share your experienced expert opinion:

1. What does it take to convert to lead free in the flux - heat - solder process??

2. Can we reuse the same machine? My point here is that the non lead free process has already coated the machine interior ( exhaust, internal flow ) with leaded component, and by conversion to lead free are we containminating the lead free product from the previous production?

I assume you mean the selective soldering machine?....if thats the case, you cannot just clean the machine ans switch over to the lead-free solder. lead-free solders are high tin content solders, which would dissolve the internal components of your "leaded" selective solder machine. all the internal parts that come in contact with the solder would have to be coated to prevent this. this is in itself an expensive exercise.
