unfortunately we encountered a serious problem during the processing batch that I reported to you yesterday about ET stamp.As you can see from the photo in attachment, the solder mask over the scoring area hasn’t been deposited on the panels.This lack doesn’t allow the tracking data to be laser engraved.Our technicians are trying to remedy the lack but I don't know at the moment if we will be able to use the panels or not.I ask you for an urgent and in-depth analysis and the necessary corrective and preventive actions.I ask you to manage everything with 8D reports.I await your prompt reply.Many thanks
