It seems that the process is being done backwards. Lead free has many alloy possibilities. The research should have been done upfront. Come up with a new replacement alloy and flux then change. The potential for boards coated with one alloy and soldered or repaired with another will be there. Very interesting.

Mustafa,
While many may be willing to share what lead-free materials have worked well for their manufacturing environment, it is still up to you or whoever makes those desicions in your organization to find ones that will work for your process. It has been stated many times that qualifying to lead-free is the same as any other process qualification. You have to start at the bottom and work your way up. Unfortunately for everyone, alot of research time and work has to go into transitioning a process from one material to another. To answer your question about which material, try talking with Kester or Alpha Metals. Both have good reputations and their materials can be found in numerous manufacturing operations.
As far as alternatives to lead-free, the answer is unfortunatley no. The choice is lead or no lead. If your company plans on selling product to Europe, then it is required that the materials used within circuit board manufacturing not contain any lead by July of 2006.
It sounds like you have alot of work ahead. I hope all goes well. If you need further assistance, contact us offline.

Dear Technetters,
Is there any lead free method which has started to apply at PCB
manifucturers?
What is the recomended material, melt pot and machine manifucturer. And also
is there any alternative method to Lead free? If there is, please give some
information about them.
