Position Overview

We are seeking a detail-oriented and experienced PCB Layout Engineer to join our power electronics R&D team. You will focus on the physical design of PCBs (including control boards, power supply boards, and high-power boards) for various power electronic products in new power distribution systems. You will be a critical link in achieving high performance, reliability, and manufacturability, directly impacting the product's electrical performance, thermal management, and EMC performance.

Key Responsibilities

PCB Physical Design\:

Independently complete the layout and routing of multi-layer boards based on design specifications provided by hardware engineers.

Responsible for designing all types of PCBs, including control boards (high-speed digital/analog signals), power supply boards (medium power), and high-power boards (high voltage, high current).

Collaborative Design & Rule Definition\:

Work closely with hardware engineers to understand and interpret requirements, and jointly define detailed PCB layout and routing constraint rules.

Provide optimal placement and routing strategies considering safety, signal integrity, power integrity, and thermal management requirements.

Power Electronics-Specific Design\:

Power Loop Design\: Optimize the layout of high-voltage and high-current paths to minimize parasitic inductance and loop area.

EMC & Safety Design\: Strictly ensure creepage and clearance distances in the layout; enhance EMC performance by optimizing ground planes, shielding, and filter placement.

Thermal Design\: Design effective thermal dissipation paths for power devices and heat-generating components, including thermal pads, via arrays, and interface coordination with heat sinks.

Signal Integrity\: Ensure the integrity of critical sensitive signals (e.g., sampling, gate drive signals) and avoid interference.

Design Output & Documentation\:

Generate all necessary production files (Gerber, drill files, assembly drawings, solder paste stencil files, etc.).

Create and maintain component footprint libraries, ensuring their accuracy and manufacturability.

Prepare PCB layout design documentation.

Design Verification & Support\:

Participate in PCB design reviews; support SI/PI/thermal simulation engineers in pre-layout and post-layout simulations.

Assist in resolving PCB-related technical issues encountered during prototyping, mass production, and testing.
