Assessing conformal coating performance
In this study the same test vehicle was used as described above, but manufactured with 1 and 3-oz copper, corresponding to track heights of approximately 35 and 105μm. The test vehicle is shown in Figure 6. The applied coatings included one of the new super hydrophobic nano coatings, two types of acrylic, and two types of polyurethane. The first acrylic was also tested after a double spray process, and both polyurethanes were tested in a thick form. Cross sections of the coatings are shown in Figure 7, the copper thickness is approximately 35 μm, from which the coating thickness can be gauged. Both polyurethanes can be seen to amply cover the track, whereas the acrylic coatings are just managing to do this, and it is not clear whether the nano coating has covered the track.
