Flexible pcb

Flexible pcb of 0.5 mm pitch is mounted with the help of conventional printing using solder paste. Capacitive based touch sensor is developed with the help of conductive ink (Ag) and dielectric inks were used for bridging over silver conductive structures.Low temperature solder paste composed of metallic based polymer binded to increase the mounting adhesion as well as with low resistance after drying. Hence it protects from short circuit when it is in “ON” mode. The electrical and mechanical characterization was occurred and it proves that this technology may give supportive solution to overcome PCB technology.
