Process for printed circuit board maufacture. |
摘要 |
<p>The method for the manufacture of printed circuit boards which have been imaged by means of a polymeric resist which comprises selectively catalyzing those areas not covered by the image by treating the imaged circuit board with a catalyst having a charge higher than the charge on the non-imaged areas and sufficiently lower than the charge on the resist image to cause the catalyst to be repelled therefrom, but sufficiently close to the charge on the non-imaged areas to cause adsorption of the catalysts thereon.</p> |
