Flexible circuits are made by applying conductive paste (with a silver base) on a polyester film with a silk-screen printing process.
Electrical part of membrane keyboards are used as simple circuits where it is necessary to contain the overall dimensions and/or connect several components on different levels.
Thanks to the technology applied it is possible to create 0.2 mm thick single or multi-layer flexible circuits with a 1 mm pitch, thereby considerably reducing overall dimensions.
They can be supplied with adhesive to make assembly operations easier.
