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.

Founder and CEO, IoT Company

Protronix EMS provided us with reliable cable assemblies and continuous on-time delivery during our product's life cycle.

MD, Agricultural Technology Company

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.
