Ordering Specifications:
- Thickness: 1.2 mm
- Surface Finish: ENIG (Electroless Nickel Immersion Gold) is recommended. While this finish is more expensive than standard HASL, it provides significantly better durability.
- Edge Connector: Gold Fingers (make sure to specify this option even if ENIG is selected).
- Gold Fingers Bevel: 45° Bevel (Chamfer). This ensures smooth and safe repeated insertions into the console.
Production Files:
- 🗺️ Interactive HTML BOM (iBOM) - Convenient interactive map for hand assembly.
- 📄 BOM (CSV) - Bill of Materials in CSV format (includes DigiKey and LCSC part numbers).
- 📦 Gerbers & Drills (ZIP) - Ready-to-order manufacturing archive.
