Lone Star Circuits

About Lone Star Circuits

The company has grown to a 101,000-square-foot facility with a staff of 55 employees. The company specializes in high-reliability PCB fabrication, including multilayer PTFE bonding, flex and rigid-flex circuits, metal-backed boards, HDI and sequential lamination, cavity constructions, and three-dimensional shaped circuitry. An in-house machine shop provides CNC vertical milling and turning with positioning accuracy of ±0.00008 in and repeatability of ±0.00004 in, alongside YAG/CO2 laser drilling, copper-filled microvias, and automated VIP hole fill. Panel sizes up to 24×50 inches are supported, with trace/space capabilities down to 0.003 in and controlled impedance held to ±3%. Surface finishes range from ENIG and ENEPIG to immersion silver, wire-bondable gold, hard nickel/gold, HASL, and tin-lead reflow. Lone Star Circuits serves the military, aerospace, and defense sectors, with customers including Lockheed Martin, Northrop Grumman, RTX, and General Dynamics, as well as transportation companies such as Alstom. The firm is ITAR-registered and holds certifications to ISO 9001:2015, AS9100D, MIL-PRF-31032, and IPC standards. The company emphasizes vertical integration, offering in-house machining, metal-backed PCB production, and rapid lead times of 24 hours to 15 days. Its focus on advanced PTFE hybrid packaging for manifolds, radiators, antennas, radomes, and tiles, combined with heavy copper capability above 5 oz, positions it for high-power RF and thermal-management applications.
