Method of assembling a circuit board into a housing

A method of assembling a circuit board into a housing to form an assembly, and fastening the assembly to a system comprising:

• inserting a first end of the circuit board into a first slot of the housing by first contacting a lower surface of the first slot that extends farther from a front of the housing than an upper surface of the first slot;
• flexing the circuit board over a deflection/retention feature by engaging a first curved guide proximate a second slot that urges the circuit board toward the second slot;
• inserting a second end of the circuit board into the second slot of the housing by first contacting a lower surface of the second slot that extends farther from a front of the housing than an upper surface of the second slot;
• pressing the circuit board into place to engage a second curved guide proximate the deflection/retention feature that urges the circuit board toward a final position until the circuit board clears the deflection/retention feature and snaps into place and engages one or more supports that help retain the circuit board within the housing, with the circuit board returning to a substantially flat state;
• and
• attaching the assembly to a system by:
• guiding the circuit board toward a connector of opposite gender on the system using one or more tapered alignment posts and one or more corresponding holes, wherein the one or more alignment posts and the one or more corresponding holes are distributed among the connector of the circuit board and the connector of opposite gender on the system;
• and
• fastening the housing to the system.
