CIMTEK

What CIMTEK does

CIMTEK, doing business as Circuit Check, is a US-headquartered (Maple Grove, Minnesota) designer and manufacturer of automated test equipment for the electronics manufacturing industry. The company was founded in 1986 and operates with 251-500 employees across a six-country footprint (United States, Canada, Mexico, China, Malaysia, United Kingdom). Its product portfolio is organized around two pillars: Functional Test Systems (standalone units, benchtop systems, line automation equipment, rotary handlers, and proprietary test software) and In-Circuit Test (ICT) Fixtures (including the Vortex Series and Tight Proximity Probing Technology), supported by Aftermarket Services (Service Contracts and the Test Partner program) and custom Build-to-Print offerings. Technical differentiation rests on in-house drilling, machining, assembly, and verification capabilities, proprietary probing technology for high-density boards, and PXI-based modular instrumentation integration. FEA and strain gauge testing capabilities are also offered for fixture design validation.

The company sells through a direct enterprise field-sales motion, where experienced test engineers engage customers on project specifications rather than via catalog or e-commerce channels. Pricing is quote-based and project-specific, with multi-year contracts typical for complex custom systems; aftermarket service contracts add a recurring-revenue layer. Customer segments are organized by vertical — Automotive, Military & Aerospace, Medical, Industrial, and Data Center / Artificial Intelligence — each addressing distinct reliability, throughput, and regulatory test requirements. Marketing is engineering-focused, relying on technical blog content, industry events, and a "Connect with an Engineer" call-to-action on the corporate website. The company self-reports as one of the largest fully integrated test solution providers in the industry, with the largest engineering staff and the largest in-house manufacturing footprint among automated test system providers. No parent company, institutional investors, M&A activity, or public listing is disclosed in the available data.
