What kind of chemicals is best to be used when finishing a soldered PCB? pure alcohol or flux-off to remove rosin flux? What brand? And is there a chemical to protect the copper&alloy from corrosion?
TIA&greetings, Brrt
I tin my pcb's with "Tinnit" after etching. You can get it from 'All Electronics Co.'. Not sure what folks are using to otherwise seal/protect.
there was just a long thread about this.

I buff the board to a shine with fine steel wool and give a light rub of liquid flux on the traces/pads, using a Q-tip. Then I tin it using thin gauge solder. The stuff melts easy and flows like water. I've used Tinnit a couple of times, and it works, but found it dulled over time and was difficult to solder onto unless buffed again. Coulda been climatic/storage conditions.
I use a coat of clear lacquer to protect the copper...works great.
