Abstract
A metallic sheet (10) is laminated between a pair of photoresist layers (26, 30) having different properties which permit one photoresist (26) to be stripped from the metallic sheet, substantially without effecting the other photoresist (30). A thin gauge blank or article (56) is photo-chemically machined from the lamination and the photoresist (26) is stripped from one side, leaving the other photoresist (30) to provide electrical insulation on just one side of the article.
