Reason of failed review,there are 4 reasons.

A:The board size is less than 75*45/75*75mm.

B:The v-cut lines are not straight and through the whole board.

C:The spacing between the V-CUT lines and copper lines is less than 0.4mm.

D:the boards thickness is under 0.6mm.

Suggestions:

A: The board size in direction for V-CUT lines should be 75mm at least,the other side which don't do V-CUT should be 45mm at least.If there are V-CUT lines in  X and Y direction ,then the board size should be over 75*75mm.

B:The V-CUT lines should be straight and through the whole board.

C:The spacing between the V-CUT lines and copper lines should be over 0.4mm to avoid damaging the copper lines.

D:The boards thickness which can do V-CUT is over 0.6mm.

E:If the 4 items can't be fixed ,the V-CUT lines can be deleted and ignored  or  the boards can arranged in our high precision factory to do ,the price will be different.
