Coating Roller Ink

The least expensive and most popular way to coat liquid resists is with a pair of roller coasters consisting of pinch rollers in which one of both rollers is used for coating.

The coating roller has a closely spaced, precisely cut spiral grove. Liquid is metered onto this roller and then transferred to the panel.

A good roller coater produces an extremely uniform coating. By carefully selecting coater parameters, it is possible to achieve a coating thickness control of 0.1 mils. Some roller coaters use the top roller as a coating roller, allowing the panel to be transported on a clean conveyor system. In these systems, the resist can be dried or the panel can be printed wet.
