Swiss Technology Group

What Swiss Technology Group does

Swiss Technology Group AG (STG) is a privately held precision electronics manufacturer headquartered in Zurich, Switzerland, operating as a holding company that unites two wholly-owned subsidiaries: GS Swiss PCB and the Hofstetter Group. GS Swiss produces ultra-reliable, highly miniaturized HDI flex, rigid-flex, and rigid printed circuit boards for the medical technology sector, with documented applications in implantable neuro-stimulators, hearing aids, electronic pills, endoscopic cameras, surgical robotics components, and medical imaging equipment. The Hofstetter Group, based in Germany, provides Europe's foremost full-service micro circuit coating solutions, offering approximately 20 advanced processes for assembly, connection technology, and final surface treatment.

STG generates revenue primarily through direct B2B sales of hardware (miniaturized PCBs) and professional coating services to medical device OEMs, operating from state-of-the-art facilities in Switzerland and Germany and serving a global client base across surgical robotics, hearing aids, medical imaging, and implants. The company is positioned as a market leader in small to medium production volumes for medical-grade micro circuits, and operates a relationship-driven, sales-led go-to-market motion targeting enterprise medical technology manufacturers. On June 19, 2026, TTM Technologies (NASDAQ:TTMI) announced a definitive agreement to acquire STG, subject to regulatory approvals and expected to close in Q3 2026, which would establish TTM's initial European footprint and integrate STG's precision capabilities into TTM's global manufacturing network.
