Q: Why would I want this solder over some other brand?

A: Kester carries a solid reputation for high quality solder and from my experience it has been great. I wanted to get some but its pretty pricey so I figured we could all split the cost for smaller packs.


Q: Why did you go with the 44 variety?

A: Kester 44 is the general go to solder that has great wetting attributes and a rosin that is not corrosive. It is not a “no clean” solder like the 245 variety but that only means that 44 leaves a little residue that does not have to be cleaned off unless you do it for aesthetic reasons.


Q: Why did you go with the 0.031” size?

A: Every time I looked up a good gauge of solder for keyboard building .031 was recommended (especially for switch soldering). Some people like a smaller gauge for more control over the amount of solder which comes at the cost of having to feed a longer strand in. The most important factor for me was that smaller gauges are pretty expensive and I wanted to keep entry into this groupbuy pretty low.


Q: How much solder is 1 Ounce (28.5g)?

A: It is approximately 25 feet/7,5 Meters. So helpful right? In my experience 15 feet was enough to cover a 60% board with leds and a macro pad and I was not conserving solder at all.
