TechNet,

As we all know HASL has been the work horse in the industry for several
years as an excellent surface finish.  The problem is the lead content as
it pertains to hazard waste, which is forcing the electronic industry to
find an alternative.

We are in the process of evaluating alternative surface finishes:

1.)  Florida CirTech's OMIKRON process(Tin)
2.)  Alpha Metal's Alpha Level
3.)  DEXTER's product

I would greatly appreciate any and all feed back as it pertains to any
alternatives to HASL.   Your responces would be greatly appreciated.
Please keep in mind the following items:

1.)  SIR Testing
2.)  Electromigration
3.)  Solder Wettability
4.)  Heat Cycling
5.)  Aging Test
6.)  Reworkablity
7.)  Ionic Contamination

Thank you for your responses,

Nate Natzke
