Use of laser marking for serial numbers, 1D, 2D barcodes, logos etc on standard rigid "FR4" PCBs seems well established where the laser etches away soldermask material.

How many users are doing the same thing successfully with flexi/flexi-rigid PCBs where the marking is made into the coverlay surface?

Thanks
