Intuitive approach 1:

Picture analysis, the pad is made without copper holes, but the pad is needed. Why should the coil be at a certain distance from the pad? The distance is 0.2mm. Our company uses dry glue technology. If there is no distance of 0.2mm, the hole cannot be sealed and the hole will have a copper hole. It is recommended that each design project must design your pad as large as possible, because it is necessary to consider that the distance between the hole and the pad is 0.2mm. If the distance between the pad and the pad is not large enough, the finished product may be a coil.

The following figure shows that if the circle you designed is not superimposed on the copper foil as shown above, and the distance between the circle and the pad is 0.2MM, then there will be two possibilities in production.

On the left, the possibility of the three holes having copper and not having copper is half and half. Because your design is not standardized, non-standardization will result in a variety of results.
