Jan Petrik

Freelance hardware engineer with more than decade of experience in hardware design.

I have gained my experience working mostly in medical, aerospace and automotive industries. I am passionate about analog electronics, power supplies and power integrity, EMC and circuit simulations. I enjoy figuring out complexities of quality hardware design, that stand the tests of EMC chamber, mass production and time. Since 2021, I’m offering consultancy, custom hardware development and engineering training.

“Jan is passionate about analog electronic development and very knowledgeable in power supplies development. He has a strong theoretical background but also a deep view about industrialization of a product. He doesn’t think only of his core expertise, but he is able to think out of his domain and provide solution regarding quality, manufacturing and total cost of ownership of the product.

When we started the new product development at Depsys, Jan contributed greatly to the success of the new product. Especially in the analog front-end design, power supply design, layout and design for manufacturing.

He is a kind person, easy to deal with, a team player and objective oriented. I personally enjoy the collaboration we have together, and I highly recommend him.”

Mathieu Tupinier, Depsys

“I was fortunate to find Jan Petrik, despite being half a world away. Jan seamlessly integrated into our team, demonstrating exceptional availability and efficiency. When a critical power supply design defect halted the shipment of thousands of devices, Jan swiftly identified the root cause and resolved the issue, allowing us to meet our commitments. I have complete trust in Jan’s capabilities across all aspects of hardware development. I wholeheartedly recommend him to any organization seeking a top-tier engineer who prioritizes excellence in every solution.”

Carl Turner, 14Hertz

“Jan has been an integral part of our complete design process including schematic capture, simulation, and component layout. He has done excellent work that gives us the trust of bringing our high density products to mass production. In theory and in hardware, his designs and knowledge have proven themselves both on paper and in test labs. Jan is our go-to when we have EMI,EMC, or SMPS stability concerns.“

Zach Solheim, Polaris

Tolerance Analysis:
A Hands-On Training

You have been selling and producing a successful product for some time. Now out of blue, the latest batch does not pass manufacturing testing. Not by a lot, but not by a little either. Production is halted, and everyone scrambles to investigate…

An elusive malfunction of your product emerges. Sending a technician and replacing the main PCB helps. Malfunction PCB tested good in your production tester. Described issue is impossible to replicate. It is not a widespread issue, one or two reports here and there…

During the final product testing, the device fails. All the subsystems passed their respective testing with flying colors. Sometime running the test many times helps. Sometimes you need to shuffle subsystem PCBs around to find a working combinations…

Make sure your product fulfils requirements across temperature range and manufacturing variance. Improve quality and reliability of your product with tolerance analysis. Are your test limits guesstimated, or designed?
