Hi
PC Board material that is stored for some time usually takes on a layer of oxidation that hinders soldering components to its surface.? In the past I have routinely used sandpaper to remove this oxidation and prepare the surface for my "ugly construction" projects.? Now I think I might have found a better way to prepare the surface.? I tried a small wire brush and found that it not only removes surface oxidation, it also leaves a much more polished surface and requires less effort.? The wire brush was purchased at a local hobby store for about $1 US, see the picture below.? If you have a small wire brush you might try it and see if it works for you.
