What Cisel does

Cisel s.r.l. is an Italian printed circuit board manufacturer founded in 1976 and headquartered in Castelfidardo, Ancona. The company designs and produces a comprehensive portfolio of PCBs including single and double side plated-through-hole boards, multilayer boards, flexible printed circuits (produced since 1984 across five dedicated production lines, in which the company self-describes as a European leader), rigid-flex combinations via its proprietary Starflex technology, and metal core / aluminum PCBs using its proprietary Thermal E material. It also offers flexible heaters for thermal management, conductive pastes, SMD/component assembly services, and continuous reel-format flexible PCBs primarily for LED strip applications.

The company's primary customer segment is automotive, where it supplies PCBs for safety-critical applications such as airbag circuits, brake control systems, parking sensors, and power steering. Additional served sectors include white goods, LED lighting, banking, photovoltaic, medical devices (magnetic resonance, drug dosage, sterilization systems), and e-mobility (large-format flexible PCBs for battery pack interconnections and temperature monitoring). Go-to-market is direct B2B sales with no publicly disclosed pricing; customers engage Cisel as a design-through-delivery partner.

Revenue mechanics are based on one-time project-based PCB manufacturing and assembly contracts. The firm markets primarily through European industry trade shows (Electronica in Munich, SMT Connect in Nuremberg, The Battery Show Europe in Stuttgart, IDTechEx in Berlin, Enova in Toulouse) and sponsorships such as the University of Stuttgart electric mobility racing project (March 2025). The company is privately held with no disclosed parent, subsidiaries, funding rounds, or institutional ownership.
