Abstract
Described herein is a system and method for securing a printed circuit board without the use of screws in a housing assembly comprising a bottom housing made of plastic and a top housing made of metal. The top housing comprises a plurality of ribs. The bottom housing comprises a plurality of flexible snap arms each having a head portion, which includes an angled lower face, a horizontal crush rib, and a vertical crush rib. Upon coupling of the assembly, the ribs exert a horizontal force on the flexible snap arms resulting in climbing of the angled lower face further onto the printed circuit board. The horizontal force may also crush the horizontal crush ribs allowing for increased flexibility between the components to adjust for interference, preventing potential damage to the printed circuit board. Vertical forces may also crush the vertical crush ribs allowing for increased flexibility between the components.
