Anonymized PCB Layout
- Application
- High-density digital processing board
- Work covered
- PCB layout, constraints, manufacturing package
- Design Domain
- Multiple high-pin-count devices, multilayer routing
Project Overview
A dense compute PCB with several high-pin-count devices. The schematic came from the customer hardware team; Yunxin owned the layout.
Engineering Challenge
Organize dense digital routing in a constrained outline while keeping escape paths and return continuity workable.
Engineering Scope
- Constraint definition and maintenance
- BGA fan-out planning
- Return-path continuity
- Plane and power-distribution planning
- DFM review
- Manufacturing output preparation
Engineering Approach
Yunxin set Allegro constraints, planned BGA escape and return paths, and released the manufacturing package.
Implementation
Deliverables
- PCB layout database
- Gerber/ODB++ manufacturing package
- BOM coordination notes where provided
- DFM notes
