Solder suggestion

**pmiller** · 07-12-2018, 08:48 PM

I need to order more solder get can't get Kester-44 63/37 .031. Is Kester 24 63/37 .031 good to use for circuit boards? The 24 is a little cheaper by about $18.

Not familiar with #24, nor could i find it on Kester’s web
Whatever you buy, check date code so you don’t get old stock and weak flux

I use #44

The the "24" you have listed is "No Clean" solder. Meaning you do not have to clean up the rosin residue left behind. I have never used it but I know a lot of folks do.

24-6337-8800 is type 245 not 24

MrGrumpy, is the one I listed okay to use? I never used no clean before so I wonder if it flows good?

245 is a great solder, and no clean is extremely helpful......cleaning is not my favorite part. I’ve used 245 at friend’s shop. Likely buy it next time

Thanks guys. I think I'll try the no clean and see how it works.

I haven't had trouble getting Kester 44 in various diameters from the major distributors-digikey, mouser etc?
I'm sure no clean is ok for digital stuff but it does leave a minute residue and IIRC is hygroscopic? We had some tiny signal analog boards that had to get ultrasonically cleaned afterward,probably not that common a problem but worth keeping in the back of one's mind.
