we use SENJU M705. type3 solder paste. Has a good shelf life.

3M jetmelt. A bit better than off the shelf reg hotmelt. Also use a GE white RTV. Never had any caps come off the board with either. DG

Believe it Bob. The shaft is not an off the shelf standard part. It is custom. My next step is build my own shaft from scratch. If I figure it out I will sell Hydra repair kits for 9000.00 ea. = /

Simply leave the paste out at the end of the shift for the next days use. Keeping the paste refrigerated just prolongs the shelf life. Even if you are at the expiration date leaving the paste out for 36 hrs won't make any difference. Jerry

In the past we have used immersion tin as an alternative for HASL. Our biggest problem was shelf life. The tin oxidized very rapidly. We switched to immersion gold and have had great success.

Silver tarnish on lead could compromise the soldering, mainly in case of No Clean process. Make sure components are correctly packaged and stored. Check the vintage ( Manufacturing Data Code) and in order to avoid them to get old on shelf make sure F

Hi Patrick, Thank you for the info, We like to push ENIG, for us being the ENIG line is in house it is cheaper to use than the carbon, plus shelf life of the Carbon is an issue in Storage. Pre-application. Thanks again, Mike

immersion silver has become my favorite finish for lead free. Seems toi have good shelf life is stored in the silversaver paper. and reflows real well. Russ

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.

Has anyone come across a standard or study (JEDEC, IPC) where it has the recommended shelf life outside of a dry box for immersion silver coated PCB's to prevent oxidation from affecting the soldering process (Both reflow and Wave). I know it will
