Steve, IPC-HDBK-001 section 5.0.5, Silver Coated Leads, pg 56 states that silver finished leads (solid) are not typically used because of silver migration (silver/tin intermetallic) which can cause solder joint failure. Evamaria Jones General Dynamics Quality Engineer Instructor ________________________________ From: TechNet on behalf of Vargas, Stephen M Sent: Thu 3/9/2006 10:10 AM To: [log in to unmask] Subject: [TN] Jumper Wires All: We need to add a 30 AWG jumper wire to a lead-free assembly (Class II). IPC-A-610 says that silver plated stranded wire should not be used due to possible corrosion under certain conditions. Our thoughts are that this (corrosion possibility) is unique to stranded wire. Would silver plated solid wire be an alternative? Any input would be appreciated. Thanks. Regards, Steve Vargas Sr. Mfg. Engineer Polaris Contract Mfg. Inc.
