- Support highly compact products requiring efficient integration of PCB board stacks and electronic components.
- Support both fiber and Power over Ethernet (PoE) product configurations.
- Design products capable of operating in approximately -40°C to 75°C ambient environments.
- Develop passive cooling solutions for products operating without internal fans.
- Integrate aluminum extrusions and heatsinks into chassis designs to effectively dissipate heat.
- Design for mechanical requirements including shock, vibration, thermal performance, manufacturability, and long-term reliability.
Thermal Design & Analysis
- Perform thermal calculations and simulations to validate enclosure and heatsink designs.
- Evaluate heat transfer paths and determine how to efficiently remove heat from densely packaged electronics without fans.
- Support product designs where internal temperatures may reach approximately 85°C to 95°C.
- Utilize FLOEFD or similar thermal simulation software when applicable.
- Review thermal results during prototype and design validation testing and make mechanical modifications as necessary.
PCB & Mechanical Integration
- Collaborate closely with electrical engineers and PCB layout resources to integrate electronics into mechanical designs.
- Define PCB board outlines, keep-out areas, component clearances, and mechanical constraints.
- Provide recommendations for component placement based on heatsinking and thermal requirements.
- Transfer and review EMN and DXF files between PCB layouts and 3D mechanical models.
- Verify component heights, placement, PCB stacking, keep-out areas, heatsink interfaces, and chassis interference.
- Support PCB and layout changes identified during prototype development and design validation.
Prototype, Validation & Product Release
- Support products as they move through Design Validation Testing (DVT) and into production release.
- Review prototype units and engineering checklists to identify required mechanical design cleanup or modifications.
- Troubleshoot new mechanical and thermal issues discovered during validation.
- Update designs and documentation based on DVT results.
- Support multiple products at different stages of development, including existing rack-mount designs and new DIN-rail platforms.
CAD, Documentation & Manufacturing Support
- Develop 3D models and detailed engineering drawings using PTC Creo 10.
- Maintain CAD models, drawings, and product information within PTC Windchill.
- Generate manufacturing drawings and STEP/STP files for product release.
- Develop assembly drawings and Bills of Materials (BOMs).
- Support engineering documentation and releases within Agile PLM.
- Develop drawing packages that can be effectively communicated to external manufacturing partners.
- Collaborate with manufacturing resources, including international factory teams, to support design transfer and production.
Sustaining Engineering
- Provide ongoing mechanical engineering support for products already in production.
- Support Engineering Change Requests (ECRs) related to alternate components, supplier issues, manufacturing challenges, and product improvements.
- Evaluate the mechanical and thermal impact of component substitutions.
- Troubleshoot manufacturing and vendor-related issues and implement appropriate design changes.
