Special Chemistries for PCM
My task today is to give you a survey of new products that most likely will make your daily work easier. First let us have a look at preparation and cleaning of metal surfaces prior to lamination with photo resist: When metal surfaces are heavily greased, greases and oils must be removed with strong degreasing media. This is done either with strong alkaline chemistry or with products that contain solvents. When the surfaces no longer contain any drawing compounds or protective greases they can be treated with new KIV-products: Surface Cleaners SC 115 and SC 220, or even with a combination of both products, to improve surface properties before the sheets are going to be laminated or coated with resist and finally etched.
