I have a board, 4 spacers needed to be soldered on the board first with the normal 62Sn37Pb alloy. Then, capacitors are manually soldered on the boards. The density of the board is quite high. If we wave soldered capacitors first, there will be no p

if your solder wave machine has a removable solder pot, consider getting a second solder pot. So you will start with a brand new empty solder pot. Keep the current one with your current solder as a backup.
