Alternative Manufacturing

What Alternative Manufacturing does

Alternative Manufacturing Inc. (AMI), founded in 1989 and headquartered in Winthrop, Maine, is an electronic contract manufacturing services (EMS) provider that delivers printed circuit board assembly and complete box build solutions to customers ranging from early-stage startups to mid-tier original equipment manufacturers (OEMs) across regulated and high-technology industries. The company operates from a single production facility in Winthrop, Maine supplemented by a prototype shop in Somerville, Massachusetts that focuses on new product introduction (NPI) and design-for-manufacturability (DFM) services. AMI's customer base spans medical devices, industrial automation, green/clean technology, robotics, military and aerospace, and technology startups, with named customers including Ori Living (healthcare), a Tier 2 aerospace and defense supplier, Scanning Devices Inc. (a 25+ year relationship), and multiple IoT and technology startups.

AMI's technical platform centers on eleven surface-mount technology (SMT) pick-and-place lines capable of placement rates up to 17,100 components per hour, with fine-pitch capability down to 0201 package size and 0.3 mm ball grid array (BGA) pitch. Quality assurance is delivered via pre- and post-reflow automated optical inspection (AOI) and X-ray inspection, while downstream capabilities include functional and environmental testing, conformal coating (silicone, urethane, acrylic), encapsulation and potting, ultrasonic welding, software and data loading, and final packaging. The company holds ISO 9001, ISO 13485:2016 (medical), AS9100 (aerospace), IPC-J-STD-001/IPC-A-610 Qualified Manufacturers Listing, and ITAR registration (June 2025), positioning it as one of the more credentialed sub-100-employee EMS providers for regulated customers in the United States.

AMI operates as a 100% employee-owned private company with 51–100 employees, using a direct sales motion driven by quote requests and collaborative design engagement rather than resellers or distributors. Pricing is quote-based and structured around three sourcing models — turnkey (AMI sources all components), partial consignment, or full consignment — with explicit 100% transparent, open-book pricing as a stated differentiator. Revenue is generated through per-build manufacturing fees for PCB assembly (classified as hardware sales) and assembly/integration fees for box build services (classified as professional services). No revenue, funding, or M&A figures are publicly disclosed. Geographic reach spans the United States, Canada, and Europe, served entirely from the Maine facility.
