     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.
