Cost
Silver is predicted to rise in popularity, it already is.



Cost - in the UK we haven't seen a significant difference in price for

SME volumes.



ENIG - we have used for over 10 years with good success on SMT product.

For thru hole where we used HASL we have switched to Silver with great

success. For mixed smt/thru builds we used ENIG but have tried silver

and found it to be much better so are looking to move to silver on all

apps except where gold is required for direct connectors or key pads. 



Regards,

 

Chris

(kinda makes me want to sing along with Burl Ives....)



We had originally planned to go to ENiG plating for all of our RoHS

boards.  But when we presented the spreadsheet showing the cost of RoHS

compatible boards, management's reaction was "gold plated boards!?  No

wonder it costs so much!"  So to placate them, we changed specs on wave

soldered boards to Immersion Silver.  But now we are getting complaints

from the suppliers.



Is everyone else finding that Silver is as expensive/more expensive than

Gold?  Is this becoming a trend?  Will fabricatoors move more and more

awy

from silver in the future?  Our manufacturing prefers gold, our

suppliers

prefer gold, now I need to find a way to justify gold as a cost savings

to

replace silver - the original cost savings.



Pete
