Great Lakes Engineering announced today that it now distributes a revolutionary solder paste. In what is a true market breakthrough, Henkel has developed the first-ever temperature-stable solder paste: LOCTITE GC 10. GC 10 is stable at 26.5°C for one year and at temperatures of up to 40°C for one month, providing benefits throughout the logistics and operations chain, while still offering unbeatable printability and reflow performance.

Certain paste mfg specify 6 hours paste thawing time to normalize the temperature. I am using solder paste softerner to spin the paste taken out from fridge for 9 minutes and measure the paste temperature in jar.It is around 26'c(same as the ambient

Pardon me for being so bold, but I still cannot understand to this day why solder paste thawing is an issue. I am not sure what types of paste you all are using but it has been my experience that the only thing you gain by refrigerating is 3 months

We've used mostly cartridges for many years and I only saw separation once when a particular paste supplier had a problem. With cartridges it's just thaw and use - no mixing. We have some sites that use jars along with mixers and I've never been co

Why not use microwave oven, it would be faster ? Be careful, rheology and all paste's characteristics are strongly dependent from the "not stressing" reaction moving from low temperature to Room Temperature. Best regards TZ

I'd be curious if a microwave would activate the flux. I'd also suspect that the metal content of solder might just give you that excellent "microwave+fork" effect. I can see this R+D failing miserably. -Russ

Sure, if your solder joints are reliabale after reflow. TZ is right about watching how you mix it, but 9 minutes sounds like it's not moving too fast. What brand of mixer are you using?

You can put metal in a microwave (at least you can mine) as long as it doesn't contact the enclosure, but there's no way you'll get consistent heating of the volume in a microwave, even if it employs a "carousel".
