Completely Opened Solder Mask Layer

Reasons for the failure of the review

The solder mask layer in your file has been completely removed. If production is carried out directly according to this file, the entire surface of the circuit board will have no solder mask protection. This may cause problems such as oxidation, short circuits or contamination during the assembly process.

This situation usually occurs when generating Gerber files using the Eagle software. To avoid such problems, make sure not to select the "Negative Polarity" option when exporting the solder mask layer.
