01 / Electronics

Electronics hardware design

Schematic and multilayer PCB design by experienced designers who consider EMI and EMC from the first placement, which helps keep compliance testing smooth. Dense, high speed and mixed signal boards engineered for performance, manufacturability and certification, including hardware we have taken through IEC 60601 medical electrical safety and ATEX hazardous area certification.
