Sick of Beige standard PCB sizes v1.0
To go along with our Sick of Beige cases we started using standard PCBs. There are two versions of varying sizes. One is a rectangle with a Golden Ratio between it's length and with, while the other is a square. All the PCBs have 4 mounting holes in each corner which are not connected to any copper on the PCB.
List of sizes
*Note: This is not a Golden ratio rectangle, but the maximum Cadsoft Eagle PCB size for users with a free license.
Hole dimensions and locations
Holes are located in the 4 corners exactly 4mm from the closest vertical, and horizontal edge. They are 3.2mm in diameter.
Cooper keep-out area
Around each hole there is a cooper keep-out area approximately 5mm from the center of the hole. In this area no traces, or ground fills are aplicable, to avoid contact with metallic standoffs,and screws.
Component placement keep-off area
No component may be placed 1.7mm from an edge of the board.
Board's round corners
Each corner of the board is rounded with a 4mm radius arc.
Reference points and lines
Runing through the exact middle, both lengthwise, and lengthwise, is a reference line. Also added are two reference point for USB mini-B jack, 5.25mm for the left and right edges.
