Multilayer material having a resistance layer formed on an electrically conductive layer and a multilayer board for a printed circuit board which has a resistance layer

摘要: An article of manufacture in form a multilayer material includes (a) conductive layer made an electrically highly material, (b) resistance formed on the layer, being electrical (c) chromate treatment by subjecting surface to and containing chromium amount 5 120 μg per 1 dm2 and, (d) silane coupling agent applying solution followed drying. The concentration is 0.001 5% weight. A board having for printed circuit boards produced laminating insulating support.
