Some of our customers believe the graphic overlay is the single most important component of the product design – it is what’s visible to the user! That is why Pannam’s graphic overlays are printed on the state-of-the-art Raster Daytona digital press. We can print more for less by eliminating the expense of films and screens used in the conventional screen-printing process. Even our most demanding customers are impressed by the four-color process and eye-popping graphics using the Raster Daytona. Pannam’s development process follows strict ISO procedures. Prior to production, you will receive detailed product drawings to ensure accuracy and completeness. Finished parts are inspected for physical and cosmetic consistency that meet or exceed your requirements and expectations. Polycarbonate and polyester are two of the most common materials used in membrane switch applications. Polycarbonate is easier to print on, die cut and emboss – making it the more cost effective but in most cases not the most prudent choice. Customers should consider that polycarbonate does not wear as well as other materials (less than 40,000 actuations), and is more prone to damage from certain chemicals. Clearly polyester is the material of choice for switches that require a large number of actuations or if the overlay is to be embossed. Generally our life cycle tests show polyester keypads can be actuated in excess of 1,000,000 times before showing any signs of wear. Polyester also has superior chemical resistance to that of polycarbonate. Customers often request lighting elements, such as LEDs, are included in the assembly to punctuate activation and provide illumination. For a uniform light over larger areas, fiber optics and electroluminescent panels are some options most commonly implemented. Overlay Feature Options:
