FINELINE CIRCUITS INC

Fineline Circuits Inc. specializes in the design and manufacturing of precision electronic components for defense and aerospace applications, with core expertise in bare printed circuit boards, printed cable assemblies, and current-carrying wiring devices. The company delivers high-reliability printed wiring boards and flexible circuit assemblies that meet stringent military and aerospace performance standards, including controlled impedance routing, multilayer lamination, and surface-mount technology integration. Their technical proficiency spans the full lifecycle of signal integrity-focused hardware, from prototype validation to low-volume production of mission-critical interconnect systems used in avionics, radar, and communications platforms. Fineline’s specialization in flexible and rigid-flex circuitry enables compact, vibration-resistant designs critical for harsh-environment military systems. The contractor maintains a consistent and deep relationship with the Department of Defense, delivering mission-critical electronic assemblies across multiple program areas including communications, navigation, and electronic warfare systems. All recent awards reflect sustained engagement with DoD procurement channels, indicating established trust in meeting defense-specific quality, traceability, and delivery requirements for ruggedized electronic components. Fineline’s primary industry focus lies in printed circuit board manufacturing (NAICS 334412), power transformer production (335311), and current-carrying wiring device fabrication (335931). These capabilities position the company as a niche supplier of high-performance interconnect solutions for defense electronics, particularly where signal fidelity, thermal management, and miniaturization are paramount. Their market presence is defined by technical precision rather than volume, serving specialized segments requiring MIL-STD and IPC Class 3 compliance. As a Women-Owned Small Business and Woman-Owned Business certified entity headquartered in Feasterville-Trevose, Pennsylvania, Fineline Circuits Inc. leverages its small business status to support DoD small business goals while maintaining agile, quality-driven manufacturing processes. The company’s geographic footprint and certifications enhance its eligibility for set-aside contracts and reinforce its role as a trusted supplier in the defense industrial base.
