What is the best solder to use of my solid state pinball machine? I need to solder new coils in place on my Elvira and the Party Monster machine. Just asking, Thanks
Best type of spider to own is the very fast pink Toed tarantula or the Golliath Tarantula. Both are venomous however , they will not kill you. It
I was bit in the fore head by a tarantula years ago (I have owned a few) Aprox 6 months before fully healed. I was teased alot saying I had herpies.
i have a roll of Kester 60/40 that i've slowly been going through for oh, seven or eight years or maybe even a decade or so. one of these is worth the price and will last you a long, long time. don't forget that it also pays to have a quality soldering iron; i prefer a digital like my Weller WESD51 (the new version of which is apparently the WE1010NA.)
i don't necessarily endorse Mouser, but here's a link to the solder i use:
63%\37% Kester from Pinball Life.
Kester Rosin core 63/37 tin lead composition is better than 60/40.
Stay with #44 flux and avoid water clean. No clean is OK but usually still needs to be cleaned anyways.
Best price per pound:
Part number 27-6337-0027 at $20 per pound.
I also prefer the pink toed tarantula, they taste better when fried.

I agree about 63/37. It flows better than 60/40. If the OP is just soldering a few coils then either is fine.
Wondering what you don’t like about water soluble flux. I used to use it for small run production because it did not require chemicals to clean—easier handling. Agree, no-clean leaves residue so you still end up cleaning.
OP, Kester solder is good stuff. Just clean the joints with a little alcohol when you’re done.
I use Radio Shack # 6400005 (formerly known as 64-005) solder on coils and on circuit boards.
6400009 is the bigger spool of the same stuff.
Water soluble flux -- if you don't clean it all off, it will eventually start eating away at exposed metal.
The 64/40 Radio Shack stuff works, i have older than dirt roll of that and it still works fine.
But it is kinda pricey compared to the Kester 63/37 solder. The Radio Shack rolls comes out to $32 to $44 per pound depending on spool size. Yet the smaller rolls will probably last a life time for some users.
The 63/37 compound works better as this ratio puts the solder right at the eutectic point. It goes straight from liquid state to solid state without an elastic state. This means less chance at cold solder joints.
