David,
        Thanks for the file info on Alloy 42. Most of the info is related
       to the solderability of the leads. I had heard that the Alloy 42
       leads were not as pliable as standard copper leads, thus intro-
       ducing a possible failure mechanism on (thin) cards prone to more
       warp and/or twist. ie:cracking at the interface
       Any comments from our component/assembly/reliability guru's?

       Is anyone using components (such as TSOP,etc.) that have alloy 42
       leads on thin card PCMCIA's? I have heard that reliability may
       be an issue (less compliancy) due to handling/assembly/encasement
       flexure. Solder joint cracking is said to be evident in reliability
       testing... Thanks
