About Us

Contract electronics manufacturing experts, assemble.

Today, we’re one of the best-regarded PCB assembly experts in the UK. Our journey began back in 1986, as Protronix Industrial Services. We worked largely with process control and instrumentation equipment.

With niche specialists and, at the other end of the scale, multinational clients pushing us to source superior components and carry out complete product manufacture, we strengthened our in-house expertise. 

Our clients – who come from all around the world, and from every sector where PCBs might feature – know our commitment to quality is second to none. Which is why some of them have stayed with us since the mid-80s. 

Competitive pricing plays its part, of course, but what matters most is total trust in that they’ll see a first-class service, no compromise on quality, and a final product that’s delivered when we promised. Even if that means production runs 24/7.

And these are products we can build to withstand even the harshest of environments. Under chemical attack. Beyond the exosphere. More than a kilometre beneath the frozen ice of the Arctic.

Protronix EMS Ltd manufactured the circuit boards for our Cryoegg instrument. They sourced the components, PCBs and did the assembly on a very short timescale ready for our field tests in Greenland in the summer of 2019. The instrument performed very well during our tests, and it was able to send us measurements from beneath 1.3km of ice.

The success and growth of our product would not have been achievable without the quality, service and flexibility we received from Protronix EMS.

Following mixed results with PCB suppliers, we approached Protronix EMS for some bare boards. They provide us with quality UL certified boards, at pricing we cannot beat elsewhere. We assemble in-house, but Protronix EMS provide all our bare boards, in various laminates, layer counts and finishes.
