Each D Style MicroPak Enclosure has multiple sets of tracks for mounting
printed circuit boards. These tracks provide an efficient and secure way to
hold your boards during assembly and testing and in the completed instrument.
The recommended board widths are 2.51 in (63.8 mm), 3.94 in (100
mm Eurocard standard), 5.28 in (134.1 mm). The recommended length is the same length as the tube.
