CoreClean was developed as a flexible surface preparation process for inner layers prior to the application of either dry film or liquid resist. It includes cleaners capable of removing the most tenacious chromate, zincate, and silane anti-tarnish treatments, and can be used with or without a microetch, and with or without antitarnish as suits the needs of the user.
MacGleam can be used as a one-step cleaner/microetch/antitarnish for preparing innerlayers or panel plate for photoresist application. It can also be used in a variety of other copper preparation processes. MacDermid also offers a line of special, patented products which improve surface insulation resistance.
