Printed circuit board breakouts and contours are normally milled. Please observe the following rules:
■Milling with a diameter of 2.0mm or 2.4mm is at no extra cost (the price for the milling distance is unaffected).
■The inner and outer contours of the circuit board should be indicated with a line width of 1µm! This prevents problems in dimensioning and measurement.
■Please avoid milling copper (durability of the circuit board, risk of injury)
Milling parameters
Sample milling diagram
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.
Milled-out portion for exactly rectangular parts
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.
Z-axis milling (level milling)
A variable level elevation can be milled at the edge or within a circuit board. This is called Z-axis milling.
Yes, PCBWay can do Z-Millilng from Top and also Bottom side of PCB.
1.Get another layer called milling or in the GM1 layer, or just add in the outline layer 2. Drawing the correct diameter of the milling in the file, also note it when place the order. 3.If you need it to be Z-axis milling, then note the depth of milling online.
