Automotive Application Thick Film Resistor Card

Thick film circuit boards Brief Introduction:
What is Thick-film technology ?
Thick-film technologyis used to produce electronic devices such asresistor card, surface mount devices,hybrid integrated circuitsandsensors by silk precision printing technology and following process drying/curing, firing, and laser trimming of resistors. Now thick film circuits are been widely applied to automotive industry, power tool circuits, LED lighting industry etc.
