Switches, Nameplates, Overlays
The production of membrane switches, overlays, labels, nameplates and one-of-a-kind specialty articles on a rush basis, as prototypes or short runs, requires special techniques and equipment. High-speed data links and state-of-the-art software are required along with laser cutting tools. These enable rapid exchange of information among suppliers, designers and customers.
ECI Screenprint Inc., a specialist in rapid turnaround and in-house laser cutting says that systematic design, production and quality control processes were created for making membrane switches and nameplates. These processes demand attention to detail and a thorough understanding of raw materials in production environments. The full line of membrane switches ranges from flexible and printed circuit board-based keyboards to multi-layered and tactile switches. Various assembly options and special finishes need to be offered in order to meet customer requirements.
Specifically, keyboards should be available as flexible, rigid, molding and PC board-based types for diverse applications. Switches should come in flat (3 or 5 layer construction), tactile (metal domes and polyester domes) and custom designs. Circuit designs need to be offered in single and double layers. Overlays and graphics should include embossed, textured, hardcoats, dead fronts, transparent windows and illuminated versions.
A major consideration for nameplates and labels is the adhesive used to apply them. Customer specifications dictate the choices relative to materials and their properties. Resistance to temperature, chemicals, solvents and humidity is a serious criterion in evaluating the selection of adhesive.
