Precision Jig for PCB Assembly

Problem Statement

Create a modular jig system that can accommodate different PCB sizes while maintaining precise alignment during manual assembly. The jig should allow easy PCB insertion/removal and provide access to both sides.

Requirements

• Accommodate PCBs from 50mm × 50mm to 200mm × 150mm
• Positioning accuracy: ±0.1mm
• Quick-release clamping mechanism
• Rotation capability for double-sided work
• ESD-safe materials

Constraints

• Aluminum construction (6061-T6)
• Maximum footprint: 300mm × 300mm
• Must be manufacturable on standard 3-axis CNC
• Budget: < $200 for materials and machining

Deliverables

• STEP files with detailed dimensions
• 2D drawings with tolerances
• BOM with sourcing recommendations
• Assembly instructions
