FCT Assembly

What FCT Assembly does

FCT Assembly (legal name FCT Solder, dba AmpOne Solder) is a privately held specialty materials manufacturer headquartered in Windsor, Colorado, that develops and sells solder paste, bar solder, wire solder, and liquid and tacky fluxes for electronics assembly and surface-mount technology (SMT) manufacturing. The company's technology is rooted in proprietary alloy chemistry, most notably the SN100CV alloy — a silver-free Sn/Bi/Cu/Ni formulation marketed as a drop-in SAC305 replacement that delivers higher reliability in drop shock and thermal cycling tests. The product portfolio spans multiple alloy families (Sn63/Pb37, Sn62/Pb36/Ag2, Hi Temp >88% Pb, SAC305, SN100C, SN100CV, LF-C2) and multiple flux chemistries (no-clean, water-soluble, RMA, halogen-free, ultra-low voiding, low/high activity). Notable technical performance claims include lead-free no-clean solder pastes capable of printing at up to 150 mm/sec, positioned as the gold standard for LED assembly applications. The AmpOne sub-brand anchors the high-performance solder paste line, with specialty lines for low-temperature and high-reliability applications.

The company operates a sales-led, direct-distribution model with quote-based pricing, no recurring revenue component, and engineering support as a core customer-acquisition lever. Sales motion is driven through the website, phone sales, technical content (white papers, Tech Tuesday webinars, SMT defect guides), and direct sales representative engagement. Target verticals include automotive electronics, LED assembly, IT and telecom, military, and solar — five segments in which reliability under thermal cycling, drop shock, and harsh environments is a primary purchase criterion. Geographic reach is domestic US with distribution into Mexico via the FCTA Mexico channel partner. The broader FCT-family ecosystem (FCT Recovery, FCT Water) and partnerships with BlueRing Stencils, A-Laser, Florida Cirtech, and Nanoslic indicate a strategy of bundling adjacent SMT-manufacturing services alongside the core solder materials business.
