Trusted by Leading Businesses

symbol
Hardware Director, IoT Connectivity Company
We had a 6-layer board running mixed-signal paths at 2.4GHz with strict EMC requirements. Their layout team resolved crosstalk and impedance matching issues that two previous vendors couldn't crack. The board passed FCC Class B on the first submission.
symbol
VP of Engineering, Consumer Electronics Brand
Their BOM optimization went beyond simply finding cheaper parts. They redesigned our power stage around a different topology, reducing component count by 22% and cutting per-unit cost by 18% — while actually improving thermal headroom by 15°C.
symbol
CTO, Industrial Automation Company
Compliance was our biggest fear — CE, FCC, and RoHS for an industrial controller with wireless modules. They ran pre-compliance EMC scans during the layout phase and built the test margin into the design. First submission, all three certifications passed. No redesigns, no delays.
