Thick Film Microcircuits are made using a combination of specialised micro screen printing and firing of layers of conductor, resistor and insulator inks on a substrate. The process begins with a schematic diagram being transferred to a set of screens for printing and firing.
Like pottery, the printing and firing is done in layers - each individual screen print is fired in an oven with the total number of prints dependent on the complexity of the circuit. A laser beam then cuts a track in the fired resistor ink, setting the precise value and tolerance of resistors. The surface mounted components, if required, are then attached and the final circuit is washed, inspected, encapsulated, labeled and every unit quality tested prior to leaving our facility.
