0.25 mm spacing between paste mask apertures. I see some designers overlap the thermal tab paste mask with the signal pin paste mask and that stencil will not work

. They will swell your outer layer pads, traces and vias to compensate for their etching process. They will trim all silkscreen that violates solder mask overlap. They

. Make sure never to design a PCB where connections have to cross, as this can cause an overlap in signals that may ruin your design

splicing tape is used. Heat Seal Splices Overlap heat seal splices are made on all FN films, except 250FN029, with an overlap that is a mini- mum of 3⁄8″ (9.5 mm) wide. On 250FN029, a butt splice is made using 120FN616 as the joining tape applied on the FEP

17.2 S009 this is broken. The sizes of the pads are way too big, so they cannot be placed (they overlap). It seems that the script files that are used to make the pads now need to use the regional decimal separator setting
