that's a good idea as far as tinning something even something quite detailed. but if you are looking for low cost and easy for water protection how about casting paraffin over the board? limiting factor would be operating temp. also a tube of silicone caulk could cover several of those boards per tube. both methods can be done after complete, also rubber cement, or even left over house paint, there are tons of ways just laying around if ya thin k about it
what can i do if i have 2 traces or a trace with a pad connected and they suppoust NOT to be connected how i can cut the conectivity?with a tiny blade? or is a better method without using a blade?
@serchmarc I use an Exacto Blade. Make multiple passes, start with little pressure then increase. If there is space between the traces I will use the back side of the point of the blade. If one or both are damaged form the blade, Jumpers can be added.
Is there not a process to spray liquid tin onto the board or something, when the manufacturers sell their boards there seems to be a sort of lacquer on them, would that not protect the copper ?
@donnyab, Well this method was chosen to keep the cost down and protect the board, I have not tried a clear coat but a lacquer would probably do the trick for the like of the lacquer, I had the soldering supply's on hand and recommend them to anyone that will be soldering surface mount components. Efficient uses of supplies!
the best is when you clean the board at the end in aerospace industry it is very important to do that leave no residue of flux on the pcb this will result in corroding the pcb .

I am a bit confused this seems very laborious.

hi, I see you are using a Metcal. What is the tip number (temp) for that curly hook?
psylux42 2 years ago
Its on a Metcal Smart Heat MX-500P-11
The Tip is a STTC-140 Its temp is 700 Deg F The tip is a 30 Deg conical Sharp Bent

can i use this tinning technique for to re-add a contact pad for a brunt through hole pad?

cool tinning technique!
but do you actually try to test the continuity of the paper at 1:29? ;)
