Reason of failed review:
See pointed area, The spacing from one hole to another is too narrow, thus we suggest to connect these holes to be a slot.
Suggestion:
Usually, the distance from one through-hole hole to another should be ≧ 0.35mm. The distance from one via to another should be ≧ 0.2mm. The distance from one unplated hole to another should be ≧ 0.2mm.
For slots, please put rectangle or oval shape slot in mechanical layer , outline layer or drill layer . The method of adding several connected holes to design slot is not recommended. Besides, The width of unplated slot should be ≧ 0.8mm; The width of plated slot should be ≧ 0.5mm.
