Imgur: The magic of the Internet
I was all set to start populating my PCBs this weekend, when I discovered I was nearly out of solder. How far do you think I can get with what’s left on this spool? I’m building a Burning Amp 3, so two driver boards, two bias boards, an input board, and PSU. No wiring yet, since my case hasn’t arrived.
EDIT: Fixed the image link. Sorry about that, been ages since I used vBulletin

Probably not enough. You'll need more soon anyway, so go ahead and order more.
Get a pound roll, it will last much longer.

Yeah, I’m going to. This roll has lasted me a long time, I got complacent. Won’t have anything before the end of the weekend, though… Let’s see how far I get 😛
Even with shipping, a pretty good deal. I get the no-clean for new parts and boards.

Ah thanks - that worked
1.7 boards 😀
I buy my solder in 5 reels at a time, to get a better price, lasts me a year or so each time, High activity 309C Henkel/loctite/Multicore 500g reels 0.7mm - great stuff - leaded of course and I used a plastic mesh sleeve from some tinned copper wire to avoifd touching too much of it day to day.

Stretch and measure it, then it´s between 1 and 2mm per solde joint, depending on pad diameter.
Count pads and do the Math.
You will do a surprising amount of soldering if those boards have solder masks, because each pad will take only as much as needed and no more, but you have not enough for that many boards.
In any case you are not wasting your time but advancing future jobs, so .....
The PSU will take a lot, because of large pads.
Well, I made it through what I have, with a bit still left over! Still waiting on the case and front-end transistors to finish it up.
I expected something like that, because I counted the windings of that reel you show in your first post. its something around 40, then multiplied it by 9cm per winding, this is a diameter of about 2.8cm X 3.14 is the length for one winding.. this would make about 3.6meter in length.. should be enough to solder three - 5 small boards..
Especially if you use a good soldering Iron, the correct heat and angle when soldering.. most times more solder is worse than less solder.. and if you use multicore with a good flux you will need even less to do the job..
Have a nice weekend
