-MLAB modules are designed in 10.16 mm raster (400 mils) and their sizes exceed 200 mils - 10 mils from the centres of the corner holes. Each module is 10 mils smaller in size compared to the exact raster due to production tolerances (otherwise it might not be possible to fit two modules next to each other on a base board). To make it possible to fit modules next to each other, it is necessary to make each size smaller by 0.254 mm (10 mils). For mounting on the [[en:albase1521|ALBASE]], we use M3 screws of 12 mm in length - that is why it is necessary to have four 3 mm diameters openings on each PCB.
