Outer corners of contours may be 90°, or rounded to your specifications.
The inner corners of contours have at least the radius of the milling tool.
Printed circuit board breakouts and contours are normally milled. Please observe the following rules:
Parameter | Value | ||
---|---|---|---|
Parameter | Minimum milling tool diameter | Value | 0.8mm |
Parameter | Smallest radius for inner corners | Value | 0.4mm |
Parameter | Minimum spacing copper / milling contour | Value | 200µm |
Application | Milling tool diameter Ø | Multi-CB Service | |||
---|---|---|---|---|---|
Application | Standard | Milling tool diameter Ø | ≥ 2.0mm | Multi-CB Service | Inclusive |
Application | Special | Milling tool diameter Ø | ≥ 0.8mm < 2.0mm | Multi-CB Service | Inclusive |
Outer corners of contours may be 90°, or rounded to your specifications.
The inner corners of contours have at least the radius of the milling tool.
To hold exactly rectangular parts, the corresponding milled-out portion should also be drilled at the corners; this permits (for example) a precise framing for seven-segment display units.

A variable level elevation can be milled at the edge or within a circuit board. This is called Z-axis milling.
