--- Quote ---There is no reason to use harsh chemicals, the copper will oxidase back immediately. The flux will remove the remaining layer anyways. Unless you have ancient PCB, with dark brown oxide layer, you will probably not need cleaning it at all. Usually the flux is enough. --- End quote --- Yes, if you get the copper wet, it will surely oxidize a bit right after cleaning and drying it. As you say, it's not a big deal if you use the board in short order. But over time it will generally get worse and it can be a bit annoying. Even with a good flux, you will need to use MORE flux and longer dwell times. Now that I'm thinking about it, the rosin flux coating would be a PITA for protoboard due to all the holes. I apply rosin flux to homemade PCBs by squirting a bit onto the board and then wiping it around with a bit of paper towel. It dissolves the rainbow sheen of microns-thin oxide that is already forming on the copper just seconds after drying it off. And the thin layer of rosin flux dries out in a few minutes, forming a protective layer against moisture and air. The board stays bright and shiny for months and the dried rosin flux aids with soldering. In the past I have used car wax, but I think rosin flux protects for longer |

My preference for cleaning copper board is the very fine steel wool used by furniture restorers. It's much more gentle than the stuff that, say, a plumber might use. It's essential that you follow that with a really good wipe using IPA on a tissue. For one off-jobs, I've been using stripboard a lot, but I keep thinking that I ought to re-visit dead bug again. |
