My suggestion would be to use the IPC-SPVC recommended SAC305

Subject: [LF] Ledafree solder Paste: SAC305 v/s SAC405

All,
We are about to select lead-free solder paste for internal use and I am
just wondering based on your real experience - should I go for SAC305
(3% silver) or should I opt for SAC405 (4% silver)?

Any suggestions/comments will be highly appreciated.

re,
Ken Patel
