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. 任职要求 --教育背景：专科及以上学历，电子工程、通信工程、自动化或相关专业。工作经验：3年以上高速、高密度或高功率PCB Layout设计经验。有光伏逆变器、储能变流器、UPS、伺服驱动器、大功率电源等电力电子产品设计经验者优先。 --专业技能：设计工具：精通 Cadence Allegro 等主流EDA设计工具。专业知识：深刻理解PCB制造工艺（层压、孔铜、表面处理等）及SMT装配流程。电气知识：熟悉IPC标准，具备基本的电路知识，能够理解原理图。专项能力：对高速数字电路、模拟电路、功率电路和RF电路的布局布线有深入理解，能独立解决相关的SI、PI、EMC、热设计问题。 --核心素质：具备较强的责任心、耐心和严谨细致的工作态度。优秀的沟通能力和团队协作精神，能够高效地与硬件工程师协同工作。具备优秀的问题分析能力和解决能力，能够承受压力。 --优先考虑条件熟悉电力电子产品常见的安规标准（如UL 60950-1, UL 1741）及其对PCB布局的要求。具备完整完成PCB设计项目经历者优先。” Qualifications & Requirements Education: Associate degree or higher in Electronic Engineering, Communication Engineering, Automation, or a related field. Experience: 3+ years of experience in high-speed, high-density, or high-power PCB layout design. Experience with power electronics products such as PV inverters, energy storage converters, UPS, servo drives, and high-power supplies is preferred. Technical Skills: Design Tools: Proficiency in mainstream EDA design tools such as Cadence Allegro. Professional Knowledge: Deep understanding of PCB manufacturing processes (lamination, hole plating, surface finishes, etc.) and SMT assembly processes. Electrical Knowledge: Familiarity with IPC standards; solid fundamental circuit knowledge and the ability to understand schematics. Specialized Skills: In-depth understanding of layout and routing for high-speed digital, analog, power, and RF circuits; ability to independently solve related SI, PI, EMC, and thermal design issues.
