Hi All, I have some question about expired solder paste. What would be some of the effects regarding assembly quality. Is there any changes in flux composition toward the end of shelf life? Thanks in advance for any replies.

. Many of our solder pastes and paste fluxes will last beyond the warranty period. Customers wishing to use “expired” paste should re-qualify the material by running test boards or parts through the entire production process to confirm good soldering results
