Stephen Driver FInstCT

Chief Executive Officer

Stephen Driver has been manufacturing PCBs of all technologies in the electronics industry for over 40 years. He has spent his entire career focused on niche and disruptive technologies and manufactured PCBs using exotic materials such as PTFE, ceramic and metal. Stephen built many PCB businesses from start-up and grew them to form a group of companies with a turnover of £18 million.

His businesses supplied PCBs across Europe into Telecoms, Automotive, Lighting, Industrial Controls, Military and Aerospace markets with accreditations across various sectors including Nadcap, ESA, AS9100 Rev D, UL + SC21 Silver Awards.

He is a former director of The European Institute for the PCB Community (EIPC) and was awarded a Fellowship of The Institute of Circuit Technology (ICT) in 2014 for his industry contributions. Stephen’s knowledge and resources provides Jiva with continued support to effectively integrate Soluboard® into existing PCB fabrication processes.

Steve Driver has been around PCBs so long, he probably dreams in circuit diagrams and measures time in layers per second. From PTFE to ceramics, he’s handled more exotic materials than a space shuttle engineer – and still finds time to make sustainability his latest disruption.
