Product Description

Thick film circuit boards Brief Introduction:
What is Thick-film technology ?
Thick-film technology is used to produce electronic devices such as resistor card, surface mount devices, hybrid integrated circuits and sensors 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.
