Hardened Electroless Nickel Glass Masters

Hardened electroless nickel glass masters are prepared by the following steps:

An iron film is vacuum deposited on a glass substrate, followed by the application of a photoresist thereon. The photoresist is exposed and developed in a predetermined pattern. A nickel film is then electrolessly deposited in the predetermined pattern after which the photoresist is removed. The iron film is etched according to the desired pattern thereby providing a circuitized glass master output.

Alternately, the glass master may be prepared by subtractive processes whereby the master is prepared in the following sequence of steps:

Electroless nickel is deposited on the iron film, a photoresist is applied, exposed and developed into a predetermined pattern. The nickel film is then etched followed by the etching of the iron film. The photoresist is then removed to give the desired circuitized glass master output.

The nickel glass masters are a superior replacement for the silver and chromium glass masters.
