  • Patent number: 10042448
    Abstract: A touch module for preventing separation of silver paste between laser etching traces, comprises a substrate, a plurality of touch electrodes, and a silver paste. A side of the touch electrode has a pin area. The pin area contains a plurality of perforations. The silver paste is coated on the substrate and the pin area for connecting electrical circuitry between the pin area and the connection line area. Wherein the silver paste on the pin area flows into the perforations and connects to the substrate. Therefore separation of the silver paste on the pin area and touch electrodes will less likely occur due to minor coating errors. The present invention also provides a manufacturing method of a touch module that prevents separation of the silver paste between laser etching traces.
