Circuit & PCBA Design

Electronics You Can Put in an Operating Room

Medical electronics carry a double burden: they must perform — driving motors at 120,000 RPM, sampling sensors in real time — and they must meet demanding safety expectations. Zlinemed’s circuit design service covers both, from concept to validation. It is the same electronics discipline behind our own ZL-HSDRILL drill controller, with its isolated power architecture and EMC-optimized layout.

What the Service Covers

Electrical Schematic Design

System architecture definition, component selection, power integrity planning, and safety-compliance-oriented circuit design. The schematic phase settles the questions that are expensive to change later: topology, isolation boundaries, and protection strategy.

PCB Layout Design

Multi-layer board design, impedance control, EMC/EMI optimization, and routing strategies for high-current and high-speed signals. Motor drive currents and sensitive analog measurement can share a board — if the layout is engineered for it.

Circuit Simulation & Validation

Analog and digital circuit simulation, power loop stability analysis, signal integrity verification, and design risk evaluation before fabrication.

Typical Applications

• Motor drive and control boards for powered surgical instruments.
• Isolated power and communication architectures (CAN, RS-485) for medical hosts.
• Control electronics for simulation devices such as pulsatile and respiration pumps.

Electronics That Talk to Software

Circuit design at Zlinemed is developed alongside embedded software — the firmware team defines the interfaces while the board is still in layout. For complete device programs, see medical device development.
