Reason of failed review:

There is no board outline/ copper layer/solder mask layer /silkscreen layer/NC-drill file in gerber files.But the order details show these layers are necessary and no any remark to clarify them.

Suggestion:

A:There is no board outline, pls add board outline layer in your gerber files,because board outline defines the shape and size of pcb.

B:If there is no solder mask layer/drill file/silkscreen layer, pls choose online parameter as “none”

C:If there is no copper layer, pls note which copper layer is empty when you place order.
