Circuit Spring, LLC

Circuit Spring, LLC, a small-business manufacturer of printed circuit board fabrication and assembly based in Lenexa, Kansas, operates as a prime contractor (100% of recent awards) serving Department of Defense customers exclusively through blanket purchase agreements, with a parent company relationship to Labconco Corp.

Circuit Spring delivers PCB fabrication, PCB assembly of microelectronic components, and full-spectrum microelectronics solutions for Department of Defense applications. Recent prime work includes a $1.285 million Blanket Purchase Agreement awarded by the Defense Microelectronics Activity on February 26, 2026, running through February 2031, which procures printed circuit board fabrication and assembly to address DOD obsolescence issues and satellite communications solutions. Performance under this BPA covers rapid production of developmental PCB assemblies for initial design use, quick production of prototype PCB assemblies for design validation, and manufacturing of high-quality PCB assemblies for operational DOD environments, with orders typically not exceeding $1.25 million and a $10,000 minimum threshold. Individual orders must be initiated within 15 calendar days and quoted within 5 days. Circuit Spring also holds a $7.5 million Blanket Purchase Agreement awarded by Naval Sea Systems Command on September 5, 2025, running through November 2029, for PCB master solutions supporting naval ship systems and related equipment. The vendor's recent footprint includes two small-value BPA calls — a $10,329 call from the Defense Microelectronics Activity awarded March 6, 2026, and a $4,150 call from Naval Sea Systems Command awarded February 11, 2026. Circuit Spring's performance capability must demonstrate in-house PCB fabrication, assembly processes, and quality control to IPC-A-600 Class 3 standards, with component procurement from authorized distributors and optional ITAR and Trusted Requirements certifications for specific work.

Customer concentration is split evenly between two DoD customers: Naval Sea Systems Command (2 awards, $7.5 million combined potential value) and the Defense Microelectronics Activity (2 awards, $1.3 million combined potential value), accounting for 100% of the source's tracked awards. The vendor's award activity launched in September 2025 and has accelerated to three awards in 2026. Four total awards under track carry a combined potential value of $8.8 million against $14 thousand in obligated dollars, with the two BPAs extending through 2029 and 2031 respectively. The combined ceiling across both vehicles positions Circuit Spring as a recurring PCB supplier for naval platforms and defense modernization programs facing obsolescence and satellite communications needs.
