Milkymist One RC1 PCB Specification

PCB Specification

In general, your pcb specifications needed to be defined well at initial stage of kicking off project. So you can just list specifications as below with your final gerber files enclosed an engineering confirmation checklist, and all send them out. Your pcb maker will make pcb for you.

• Six Layers PCB
• Board Dimensions 150mm x 125mm in piece, 158mm x 133mm in panel
• 10mil drill via hole pth
• top & bot line width/line clearance, 5mils/5mils
• top & bot 5mil annular rings
• 1.6mm +- 0.05 mm thickness.
• FR4
• Components placed on TOP & BOT layer.
• Stacking of layers: 1st layer Top/Compnents/Signals, 2nd layer Gnd, 3rd layer Signal, 4th layer Gnd, 5th layer Power, 6th layer Bottom/Components/Signals.
