Hi Dick We've built up an SMD line for low volume, high product mix over the last two years. Some thoughts: - the reflow system shall have very big thermal power and reserve that results in the same profil with different thermal masses ie products. T

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
