About

With more than 20 years of hands-on experience in quartz glass manufacturing, processing and engineering, I specialize in turning complex quartz requirements into reliable, production-ready solutions. My focus covers laser processing of quartz glass, CNC machining, precision welding, measurement & quality validation, as well as design-for-manufacturing for demanding semiconductor and high-tech applications. Prior to founding bokTECH, I spent over a decade at SemiQuarz, where I was deeply involved in quartz component manufacturing, cold machining, construction and production leadership. This background shaped my understanding of quartz not just as a material, but as a critical process component within semiconductor and advanced manufacturing environments. At bokTECH, we combine deep material expertise with practical manufacturing know-how – from prototype to series production. Our work is driven by precision, process understanding and long-term reliability rather than short-term fixes. I strongly believe that successful quartz solutions emerge where engineering, manufacturing and application knowledge meet – and where partnerships are built on technical trust.
