Hi David!
I have done some initial investigating of the AlphaLevel finish and
was encouraged by its performance. The investigation results were
reported as part of the paper: "Wirebondability and Solderability of
Various Metallic Finishes for Use In Printed Circuit Assembly", SMI
Conference Proceedings, 1996, page 687. A paper on the finish was
also published in the IPC 1996 Expo proceedings, "Alternative Metal
Finishes for Wire Bond and Soldering Applications", by Steve Beigle,
page S9-2. I think that there is quite a bit of room for more
investigation to be completed - there a several companies/individuals
working on testing right now. I believe that there will be a paper on
the finish at the IPC 1997 Expo too. Give Frank Kurisu, SolderMask Inc
of Huntington Beach CA 714-842-1987, a call for more info - they were
going to set up a plating tank and begin processing real product. I
have concerns on the possible migration of the finish under certain
conditions and voltages but the published SIR data to date has been
good. Good Luck.

Hi all,
Is anyone out there using AlphaLevel as a board finish?
If so, what are your thoughts:-
Good?
Bad?
Ugly?
Cheap?
Expensive?
Any comments are appreciated.
