GS Swiss PCB

What GS Swiss PCB does

GS Swiss PCB AG is a Swiss specialty manufacturer of highly miniaturized printed circuit boards (PCBs), founded in 1981 as GS Präzisions AG by the Nerpas family in Küssnacht am Rigi, Switzerland. The company produces flexible, rigid, and rigid-flex PCBs along with IC substrates and chip-on-flex/cavity substrates, exploiting advanced Ultra-HDI manufacturing technologies including mSAP (modified semi-additive process) and SAP (semi-additive process) that enable trace widths and spacing down to 10 micrometers — roughly one-sixth of a human hair. Production is conducted at a single 5,600 m2 Swiss facility with four cleanrooms operating 24/7 in three shifts, supplemented by laser direct imaging, laser micro-via drilling (50 µm standard, 15 µm limit) and a range of surface finishes (ENIG, ENEPIG, DIG, galvanic gold).

The company serves mission-critical applications in medical technology (hearing aids, cochlear implants, pacemakers, blood pumps, ultrasound probes, electronic pills), aerospace (satellites, the NASA/JPL Mars Rover), and scientific research (thousands of PCBs for CERN's Compact-Muon-Solenoid detector, for which it received two CMS Gold Awards). Notable customers include CERN and NASA/JPL, alongside unnamed hearing-aid, ultrasound, and implant manufacturers. Certifications include ISO 9001 (1994), ISO 13485 (2025), UL E79891 for rigid PCBs, and full RoHS/REACH compliance.

GS Swiss PCB operates a direct enterprise field-sales model, with regional sales managers across Scandinavia, the UK, and German Switzerland, plus dedicated Business Development Managers and a US sales subsidiary (GS Swiss PCB Inc., Woburn, MA, est. 2015). Revenue is generated through custom, quote-based hardware sales of specialized PCBs, with feasibility analyses conducted prior to quotation. The company has scaled to over USD 50 million in revenue on approximately 200 employees. Ownership history includes founder-family control through 2006, integration into the exceet Group (Frankfurt-listed, 2010), and a 2021 acquisition by Swiss private equity firm Afinum via STG Swiss Technology Group, the latter of which brought Hofstetter PCB AG (Europe's largest plating company) into the group as a sister company in 2023. In June 2025, TTM Technologies (NASDAQ:TTMI) announced a definitive agreement to acquire STG, expected to close in 2026 subject to regulatory approval.

Products and services

• Flexible PCBs (Flex PCBs) Bendable printed circuit boards made from flexible materials such as polyimide, designed to fit into compact, irregularly shaped spaces and withstand demanding environmental conditions. Manufactured since 1995 for medical implants, hearing aids, and other space-constrained applications.
• Rigid PCBs Stiff circuit boards made from solid substrate materials such as glass fiber reinforced epoxy resin (FR4), characterized by rigidity and strength. The company's foundational product, manufactured since its founding in 1981.
• Rigid-Flex PCBs Hybrid printed circuit boards combining the robustness of rigid PCBs with the flexibility and adaptability of flexible PCBs in a single integrated solution. Used in implanted blood pumps and other complex medical and industrial applications.
• Ultra-HDI PCBs Ultra-High-Density Interconnect printed circuit boards designed for the most extreme miniaturization requirements, leveraging the company's mSAP and SAP process capabilities.
• IC Substrates Highly integrated substrates that solve the problem of dense chip structures being too dense to solder directly onto a PCB, enabling connection on one side with the IC and on the other side with the PCB. Manufactured using ABF and advanced mSAP/SAP techniques.
• Chip-on-Flex Substrates (COF) Flexible PCBs that are thinner than rigid counterparts, supporting complex designs that can bend and fold into various shapes and eliminating cables and connectors. Direct chip mounting on flexible PCBs improves performance and flexibility while reducing weight and space.
• Cavity PCBs for Chip-on-Board (COB) PCBs with cavities that enable the embedding of naked chips and other components. Materials like epoxy can encapsulate naked chips for protection while saving space and improving performance.
