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
