Having worked with a new customer through their prototype phase, following product launch, we built initial small batches to satisfy pilot orders. As the customer scaled, we scaled production to meet their demands.

Hundreds of units turned into thousands and then tens of thousands of units, culminating in a total of approx. 250,000 units being produced, at a peak production rate of 5000 units per week, over a number of months.

PCB assembly, both SMT and THT, programming, test, configuration, final assembly, barcoding and packaging, all completed in house.

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.

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.
