[edit] 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. Please note, pcb manufacturers after receiving gerber, usually a more detailed breakdown of the production of works recognized, see the Notification.

  • 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.

[edit] Notification

General pcb industry, pcb designer will inform the pcb industry in all the through hole is to be all-plug hole process. But this process must follow the pcb industry's own processes can in each though hole can support all plug holes. To this rc2 production process, pcb industry informed the U10 through hole 30 near the aperture design is a 24 mil. the actual hole diameter is 21 mil, due to pore size is too large to plug holes for solder coating. In other words, while noticing pcb manufacturer to produce PCBs, the need to plug holes and using some non-plug hole is to be clear clarification or mark that the area to facilitate.
