About Rocky Mountain Circuits
Rocky Mountain Circuits operates from Longmont, Colorado, where it has fabricated printed circuit boards since 1972. The shop produces double-sided through 24-layer multilayer boards, including rigid, flex, and rigid-flex constructions. Processes cover blind and buried vias, filled vias, sequential lamination, microvias, controlled-depth milling, backdrilling, and impedance modeling with 3-mil line/space capability. Surface finishes include HASL (lead-free and standard), ENIG, and immersion silver. Materials range from standard FR4 to high-frequency Rogers, Taconic, Nelco, and Teflon substrates, plus aluminum-based boards for thermal management. The facility also assembles custom cable harnesses and provides box-build integration, offering a prototype-to-production flow with quick-turn options as fast as 48 hours and standard leads of 10 days. Offshore partners handle higher-volume runs. Customers span medical devices, industrial automation, automotive electronics, consumer products, semiconductor test, Internet of Things, energy systems, and network/telecommunications infrastructure. The company cites work in each of these sectors on its website. Rocky Mountain Circuits attributes its longevity to a philosophy of building high-quality product, delivering on time, and pricing competitively. It emphasizes rapid turnaround, UL-approved material compliance, and a one-stop model that includes fabrication, assembly, cable, and box-build services.
