Modular circuit board stackable structure

Abstract

This disclosure provides a modular, stackable circuit board structure, comprising a first circuit board assembly, a second circuit board assembly, a plurality of first nests, a plurality of second nests, a plurality of first polygonal fixing posts, a plurality of second polygonal fixing posts, and a plurality of screws. The second circuit board assembly is located above the first circuit board assembly. The first nests are disposed below the first circuit board assembly, and each first nest includes a first polygonal hole and a first screw hole. The second nests are disposed between the first and second circuit board assemblies and include a second polygonal hole and a second screw hole. The first polygonal fixing posts pass through the first polygonal holes. The second polygonal fixing posts pass through the second polygonal holes and protrude into the first polygonal fixing posts. Screws are engaged in the first and second screw holes. This allows adjustment of the number of circuit board stack layers.
