ACDi

What ACDi does

ACDi (American Computer Development, Inc.) is a privately held U.S. electronics manufacturing services (EMS) company founded in 1984 and headquartered in Frederick, Maryland, with a second manufacturing plant in Nashville, North Carolina. The two AS9100D-, ITAR-, and NIST 800-171-certified facilities total approximately 110,000 sq ft and run PCB assembly, box-build and systems integration, new product introduction (NPI), test and inspection (ICT, flying probe, AOI, X-ray), product lifecycle and obsolescence management, and, via a partnership with LogiSync, PCB layout. ACDi is owned and led by founder Bill Hornbaker (President and CEO) and has been built without external venture or private equity capital, growing primarily through two acquisitions — Patapsco Design (2004) and Fawn Electronics (2012) — that added quick-turn assembly, nuclear-compliant manufacturing, and cable/harness capabilities.

The company sells exclusively through a direct enterprise field-sales model to aerospace and defense, medical device, industrial electronics, and reshoring OEMs, with territory-based Directors of Business Development in Tampa, FL and New Stanton, PA. Pricing is quote-based per project or per program, with no public pricing tiers; revenue is generated by billable EMS units and engineering services such as DFM/DFA and Kanban replenishment programs. ACDi is a small-business, SAM-registered supplier holding ISO 9001:2015, ANSI/ESD S20.20-2021, and RoHS certifications alongside its defense- and aerospace-grade accreditations, and reports more than 11,000 projects completed since founding, including a 2025 Circuits Assembly / PCEA Service Excellence Award for Responsiveness. The business model is fundamentally relationship-driven, low-to-mid volume, U.S.-domestic EMS with embedded DFM engineering, where the "Honor the Schedule Pledge" and codified DFM/DFA guidelines function as soft-asset differentiators in regulated end markets.
