Kester24-6337-0010 44 Rosin Core Solder 63/37 .020 1 lb. Spool

Q: Would this work well to solder switches to a PCB on a mechanical keyboard?

Yes, this is excellent solder for electrical applications. However, keep in mind this is a large roll that is a lot more then you would need if you are only doing one keyboard. I work on home electronics all the time and still l have a roll I bought at least 3 years ago that I use almost weekly. If you only need a small amount I would recommend you go to sparkfun.com they sell small quantities of solder for small jobs, it may not be Kester brand but it is good solder for your job.

Q: Is this a multicore solder?

All Kester Solder products are single core.

Q: The diameter of this solder is less than 1/32?

1/32" is 0.031", so yes, even if it actually measures out to .022" it is smaller than 1/32" This product is available in 0.031" if you prefer a thicker solder.

Q: Does the Kester 44 solder have a shelf life or expire in x number of years?

The jist: it lasts forever in a dry, non corrosive environment. The expiration date on the box is for the manufacturers warranty.
