PCB Specification

MM1 RC2 pcb definition of stack up which is same as RC1.

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.

QA Outgoing Inspection Report from PCB maker

The following inspections based on your data sent to pcb maker. Those details of inspection report would exactly more than yours.

  To Be Added.

Micro Section of PCB

To be Updated pictures soon.

• Mm1 rc2 pcb stack up.png

  PCB stack up is made at initial stage of routing. In general this data is defined by customer design side not pcb maker. So if you don't request pcb maker follow a specific stack up, they will use the most popular stack up. You should ask pcb maker to provide this data. For MM1 project, we defined this to let pcb maker follow it.

• Mm1 rc2 cut square hole for micro section.png

  PCB Maker used J3 reference to do the microsection inspection.
