We have a customer who says that a previous supplier had problems soldering
some fine pitch components (15 mil) because the lead material was "Alloy
42".  They had a tin/lead coating (85/15).  They were also told that many
component mfgrs are going to be using this material.

We are not familiar with this lead material but since it is solder coated do
not hink it should be a problem.  Anyone have any knowledge or experience in
this area?  

Thanks in advance for your consideration.
