Each E 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.
If you have the flexibility to design to MicroPak standards,
you will achieve significant cost effectiveness both in terms of enclosure
cost and assembly cost. 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 cover and base.

Shorter boards may be secured by fastening to a single standoff located
near one end of the board (being sure that no components are located in
such a way as to impede the board from being slid into place). The same
technique can be used to electrically ground a board to the base.
