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".

Good morning, Solder paste softeners are designed to allow solder paste reach ambient temperature during shorter time period (only 5-10 minutes instead of hours). You are preparing your material in right way. No reason to worry. BR, Pavel

Do you allow them to thaw to roo temp. before use?

Hi, can someone give definition on pot life? does the pot life start once it's been taken out from fridge or the pot life starts once recommended thawing ends?
