Reason of failed review: Normally, for 1 order, only 1 gerber file is needed. But in your file, there are several gerber files.
Suggestion:
1.Do you want us to make panel of these files? If so, do you have any demands of panel? Do you accept the X-Out Allowance in panel(Bad pcbs exists in panel)? We will mark “×” on bad pcbs.
2. Do you want us to make different single pieces? If so, next time, we suggest to put several pcbs orders. We can combine shipping and they will be in 1 package.
3. If only 1 gerber file is needed, pls check and tell us which file is correct one.
