Ken, best to use Sn62 (Silver bearing) solder on any component with Silver plated terminations. It retards leaching of the Silver from the termination during soldering.

[mailto:[log in to unmask]] Sent: Thursday, June 22, 2000 17:46 To: [log in to unmask] Subject: [TN] Termination/Soldering Combination We are planning to solder some surface mount capacitors with palladium-silver terminations on our printed circuit assemblies using tin-lead (SN63/37) solder. Does anyone know of any long term reliability problems with this termination alloy/soldering combination? We can get these capacitors with nickel-tin terminations. Given that our solder is tin-lead, does anyone know whether one of these termination alloys would be preferable to the other? Thanks for any insight you may be able to provide. ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
