How To Clean A Circuit Board After Soldering. Flux residues can affect the isolation resistance of the board surface, but also on clean boards this might be an issue. To kill a circuit board:
Here’s how to clean as you solder: Alternatively, spot clean your circuit board with isopropyl alcohol. Acetone solution is used to soak pcb boards for about 10 minutes.
If the circuit board is full of dust, flux,dirt or whatever thing (objects or liquid) i will make sure that i clean the circuit board first before i do the repair work.
Alternatively, spot clean your circuit board with isopropyl alcohol. I saw but, is it actually safe for a soldered pcb? The solder helps form a heat bridge between the nozzle and the solder on the circuit board that needs to be molten. Pure water is a poor conductor of electricity.
