Hello Rich, The component vendor does not seem to understand the soldering process. You need to reflow to suit the solder paste not the metal being soldered to. regards, Phil. -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Richard Kraszewski Sent: Thursday, 26 October 2006 2:47 PM To: [log in to unmask] Subject: [TN] Backward Compatibility of Tin Electroplating Does anyone have any reason to suspect that tin electroplated SM components being soldered with a 63/37 solder paste require a profile that must exceed the reflow temperature of tin? Being told by a component vendor this is the case. I would totally discount this but seem to recall reading this more than once on some other component Tech data sheets. I can't explain why this would be necessary, but..... Any thoughts would be appreciated.
