If "No" is selected, the half holes will not be plated with copper. If there appears to be plated half holes in your design, but the option for castellated holes is not selected, we may contact you directly to confirm whether castellated holes are required.
How to indicate castellated holes in your design?
Castellated hole design varies from software to software, but the end result in the Gerber files should be as follows. Please refer to the documentation of your chosen design software for more information.
Add a via or plated hole directly on the outline of the boards where the plated half hole is required. Ensure that half of the via is on the board and half is on the outside of the outline.
The following should be included:
- Copper layers (GTL and GBL): Copper pads on both top and bottom copper layers for each castellated hole.
- Solder mask layers (GTS and GBS): Solder mask openings on both sides.
- Drill layer (TXT/DRL): A drill hole for each castellated hole.
- Mechanical/Outline layer (GML/GKO): The outline should cross the drill hole.
