We have been working with lead free alloys in HASL machines since '98 and
have been leveling panels commercially for about 5 years. What would you
like to know?

Subject: [TN] Lead free solder HAL


Good Morning Technet,

I am at the early stages of learning about lead free solder as an
alternative option to our current tin/lead solder HASL.

Is there anyone out there who can comment about their experiences?

Currently I have no customers requesting this process, but I need to be
ahead of this need when feasible.

Vendors have provided both sides, yes PCB makers are doing it and a large
PCB maker tried it and discontinued using it.

Thanks in advance.

Russ Burdick, trying to lessen the HASL hassle
