The product is an integrated membrane switch featuring an ESD shield, a rigid display window, embedded LEDs, and pillow embossed tactile switches.
MNR Technology was asked to resolve performance problems with this product, including color stability, tactile switch consistency, and ESD performance stabilization.
We identified numerous errors in the earlier design. We updated the design to assure proper venting and ESD shield layer-to-layer interconnection. Additionally, we increased the insert window thickness. We also established color standards for all printed colors. This included spectral data confirming that the colors are printed to these standards.
The product now performs as expected with ESD performance to industry standards. Additionally, the product has a crisp, tactile feeling along with clear, appealing graphics.
