Hi Netters and Free folks,

I have a good one about lead-fee. It is common knowledge that lead-free
materials and a process have to be qualified. But what would this mean?

OK, I chose the SMTA Saber board as a test vehicle. I approached a few paste
suppliers and I will probably use the products of 2 or 3 of them to stuff a
certain number of boards. I will get support and tweak the reflow and wave
recipes, let's consider this done. But, what next?

First of all, what quantity of boards would be a good test batch for each
different paste?

Then, I must confess that I am not a reliability guy, so what tests should I
perform? Cleanliness (is it really necessary?), pull tests, vibration? What
accelerated joint reliability tests to do? Simply go through IPC 9701 and
pick something that matches the application?

Any clue would be largely appreciated.

Thanks,
Ioan
