soldering flux
Can I use Plumbers flux to solder SMD caps to a board? I've got the yellow stuff and some white flux which is great for soldering copper pipes.

I suspect it wouldn't be the best plan. Solder paste is usually acid based so might hurt the PCB - most soldering flux is Rosin based.
Check eBay for Topnik RF800 - it's pretty cheap and very good! |

I've got 2 types of solder on my van, LA-CO which is non acid & non toxic and powerflux for lead free solder. The powerflux is easily the best for copper pipes but it looks like the LA-CO should be OK. Thoughts?

The powerflux has a PH <2. The LA-CO doesn't say what it's PH is but claims non acidic. I'd prefer to use what I've got instead of buying something I'll never use again.

Do not use plumbers solder under circumstances it will eat the board up and create a mess, Topnik RF800 liquid flux is great cheap flux. a little goes a long way

DO NOT EVER use plumbing solder or flux on electronic components! Buy some proper flux, it'll only cost you a few dollars.
