Micro-Precision Technologies (MPT) manufactures electronic circuit boards that are printed on ceramics to withstand environmentally adverse conditions in which high levels of thermal conductivity are required. The firm has expertise in building multi-layered thick film substrates, which are composed of ceramic that is screened with conductor, insulator, and resistor material to form the circuitry. These thick film substrates have been used in: submounts, amplifiers, oscillators, synchro converters, resistor networks, regulators, and filters.
