The electronic circuits and LED display are often incorporated for real time application system by using PCB and MEMS technology. In this prototype, electroluminescence display and touch sensitive sensor circuitry is printed with the help of screen printing technique and also formulation of low temperature solder paste for mounting of electronic components on glass.Electronic components referred to SMD type and printing of solder paste patches by using stencil printing on glass. The electronic circuitry for printed EL display and touch sensitive sensor (capacitive) shows the main advantage where it can also be re-programmable with respect to sensitivity.

Keetronics developed a printed flexible heater for real time applications (Heat Therapy – Healthcare applications).It is fullyprinted resistive heating elements with conductive low resistance traces and unique high resistance arrays for heating surface applications, can create self temperature controlling heaters utilizing positive temperature coefficient (PTC) technology, or printed thermocouples to measure temperature. It works under the principle of electrical coil, where the magnetic flux induces with respect to voltage and current, achieved with the help of printing on flexible substrates. By control of dimensions and ink compositions these products offer precise resistance specifications without the need of resistor trimming. These heaters are safe, flexible, long durable and cost effective.

Foil heater high conductivity and induce magnetic flux with respect to voltage. The conductive materials are deposited on to the flexible substrate with the help of conventional screen printing techniques. Printed flexible heaters, thin construction and low mass designs allow heat to transfer more efficiently than foil imprinted heaters. Uniform part temperatures are assured by matching power.

PTC heater can create self temperature controlling heaters utilizing positive temperature coefficient (PTC) technology, or printed thermocouples to measure temperature.

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.
