Oh yeah, I've seen this before! Generally, if the hole sizes are correct (including plating), and the PEMs are within spec, we've found that this is most commonly caused by insufficient support of the PCB during insertion. If you can eliminate supp

John, I believe that your problem is cuased by inadequate filling of the transformers with potting material - if any is used at all. When you attempt to clean, particularly with a chemistry, it is designed with wetting agent, surface tension modifier
