Hello everyone,

I have come across a method used to tin pcb copper tracks that is based on a product named ROSOL 3, by Rothenberger. It is a material used by plumbers and consists of copper and tin, as far as I am aware of.
So you apply it on the whole pcb surface, then use a thermal gun (or oven) at 200-250 degries Celcius, and as soon it is dry, you wipe the excessive material using a toοthbrush in a bowl filled with water.
Seems to work in a video I have watched.

Does anyone in here know about such a method, and whether it is efficient? Thanks in advance!

I've not used that particular method - but something similar.

We would heat up a track with the soldering iron, then apply solder and let it flow. We then wiped off the excess solder, while it was still molten, with a damp cloth. If you take off the iron and do the wipe in one swift movement (with a bit of practice) you can get excellent results.

Good luck - and don't burn your fingers.
