PCB Layout Engineer

Job description

Role Summary (P17) The PCB Layout Engineer is responsible for designing multi-layer PCB layouts for power electronics hardware such as AC-DC rectifiers, DC-DC converters, inverters, onboard/offboard chargers, SMPS, gate drivers, and control boards. The role focuses on high-power, high-voltage, high-frequency layout, ensuring thermal performance, EMI/EMC compliance, safety isolation, and manufacturability. Key Responsibilities • PCB Layout Design (High Voltage / High Current / High Frequency) • Design multi-layer PCBs (2–12+ layers) for: – Power stages (MOSFET/IGBT/SiC/GaN) – Gate driver boards – HV/LV sensing circuits – Digital controller boards (MCU/DSP) – Auxiliary power supplies • Optimize layout for: – Low loop inductance – Controlled impedance traces – Creepage & clearance for HV designs – Short gate loops and Kelvin source routing – High current copper thickness and pours • EMI/EMC-Optimized Layout • Apply best practices for: – Minimizing switching noise – Grounding strategy (AGND/DGND/PGND separation) – Shielding and filtering – Common-mode noise control – Differential pair routing (CAN, LVDS, Ethernet) • Thermal & Mechanical Considerations • Design layouts supporting: – Heat spreading – Thermal relief, thermal vias – Heatsink and busbar interface – Component derating and spacing • component supports & PCB mounting considering vibration/shock • Work with mechanical team for 3D integration. • Compliance & Safety Layout • Ensure PCB meets: – Creepage/clearance per IEC/UL standards – Insulation requirements for HV (>800 Vdc) – Automotive or industrial safety rules • Design as per IPC/IEC standards • Design isolation barriers with proper spacing and cut-outs. • Design for Manufacturability (DFM) & Assembly (DFA) • Apply DFM/DFA rules with PCB fabs and assemblers. • Prepare fabrication files Gerber/ODB++, Drill files, Stack-up, Mask files, Assembly drawings, Pick & place data • Generate 3D models of the PCB • Perform /coordinate Signal integrity and Power Integrity Analysis • Library & Documentation Management • Create and maintain symbols, footprints, and 3D models. • Maintain layout documentation, revision control, and release notes. • Cross-Functional Collaboration • Work with: – Power Electronics/ Hardware circuit designers – Embedded/control engineers – Mechanical engineers – Manufacturing and quality teams • Participate in design reviews (DR0/DR1/DR2/DFM review). Technical Skills Required Skills & Qualifications • Strong experience in PCB layout for power electronics converters. • Experience in layout of Control boards with DSP/microcontrollers/FPGA • Expertise in: – High-voltage (400V, 800V, 1500V) – High-current (>100A) – High-frequency SiC/GaN switching layouts • Knowledge of EMI/EMC and grounding rules. • Strong understanding of analog, digital, and mixed-signal routing. • Understanding of PCB manufacturing constraints, soldering and assembly process • Good understanding of IPE /IEC standards for PCB layout (IPC2220series, IPC7531 etc) Ability to read schematics and understand converter topologies. Tools • Cadence Allegro / OrCAD • Altium Designer • Mentor Graphics (PADS/Xpedition) • ECAD-MCAD integration (SolidWorks/Creo) Experience • PCB layout experience in AC-DC PFC, LLC/DC-DC converters, Inverters/traction converters, EV chargers / BESS modules and their controllers • Experience with wide-bandgap SiC/MOSFET modules is an advantage. Qualifications • Diploma / B.E / B.Tech in Electronics, Electrical. • Experience Levels 4–10 years with 4+ years in PCB layout Preferred Experience • Circuit Design experience. • Hands-on knowledge of Kelvin source routing, Snubber loop optimization, Gate driver–power stage co-layout • Knowledge of simulation tools (ANSYS SIwave, HyperLynx) preferred. • Familiarity with safety standards (UL, IEC 61800, IEC 61000).
