Reason of failed review: For your panel file, it has distance between pcbs. And the distance is smaller than 1.6mm. Pls check and tell us which one we should follow: 0mm V-Scoring, 3mm V-Scoring or Tab Route.

Normally, for the panel, it has V-Scoring and Tab Route.

For V-Scoring, it has 0mm distance V-Scoring and 3mm V-Scoring between pcbs.

For tab route and stamp holes, it can used in the irregular boards. However, for tab route, the space between boards should be 1.6mm. 2mm is the default value.

Suggestion:

1. If there is no component out of outline and the outline is regular shape, we suggest to  choose 0mm V-Scoring.

2. If it is irregular shape, we suggest to choose Tab Route;

3. If you need distance between pcbs, we suggest 3mm or Tab Route.
