Learn More

CMS Circuits manufactures high-reliability thick-film and hybrid microelectronics using precision screen printing, laser processing, and advanced assembly on ceramic and specialty substrates. From prototype to full production, our processes support aerospace, defense, medical, semiconductor, and high-power electronics applications requiring mission-critical reliability.

Printing & Deposition

Screen-printed conductors, resistors, and dielectrics on ceramic — down to 0.001" line widths, fired for permanent bond strength.

Laser Processing

Laser trimming and scribing for precise resistance values and clean substrate cuts — tolerances down to ±0.1%.

Assembly & Placement

SMT and wire-bonded component integration into compact multilayer modules, built for mission-critical environments.

Finishing & Protection

Protective coatings and encapsulants applied to extend circuit life in harsh thermal, chemical, and mechanical conditions.

Inspection Capabilities

100% electrical test, visual inspection, and full lot traceability — every unit verified before it leaves the facility.

Materials & Substrate

Alumina, aluminum nitride, beryllium oxide, fused silica, and ferrite — matched to your thermal and electrical requirements.
