Circuit board enclosure

An apparatus comprising:

• a base unit having a wall, said wall having a top edge that defines an engagement portion;
• a top cover having an upper side and a lower side, said lower side defining an engagement portion;
• and
• a plurality of stackable enclosure units each comprising a spacer and carrier, said spacer defining a wall and having first and second engagement portions on an upper side and a lower side of said spacer, respectively, and said carrier defining at least one mounting portion configured to receive a circuit board and having first and second engagement portions on an upper side and a lower side of said carrier, respectively;
• wherein:
• said second engagement portion of said spacer engages with said first engagement portion of said carrier;
• said first engagement portion of said spacer engages with either said engagement portion of said top cover or said second engagement portion of said carrier of said stackable enclosure unit overlying said spacer;
• said second engagement portion of said carrier engages with either said engagement portion of said base unit or said first engagement portion of said spacer of said stackable enclosure unit of said underlying stackable enclosure unit;
• and
• the plurality of stackable enclosure units is assembled between the base unit and the top cover to form an enclosure for circuit boards mounted to the carriers.

A method of enclosing a plurality of circuit boards, said method comprising the steps of:

• selecting a plurality of circuit boards, said circuit boards having various functionalities;
• mounting each of said selected circuit boards onto a carrier, said carrier including an engagement portion for receiving a mating engagement portion on a spacer, said spacer defining a wall;
• joining said carrier engagement portion with said spacer engagement portion;
• and
• stacking said joined carrier and spacer to produce an enclosure.
