ABSTRACT:
Many circuit boards include conventional sockets for receiving optional ICs. Such sockets are soldered to the circuit board during the manufacturing process. However, many of such sockets are wasted because they are never used. Such waste can be eliminated by using a clip-on IC retaining apparatus. It includes a housing, a retaining clip, and four registration holes arranged at the comers of a trace pad on a circuit board. The housing includes a shallow, open cavity on a bottom side for receiving a SMD. Four registration fingers projecting from the bottom of the housing mate with the registration holes on the circuit board to align the pins of the SMD with the trace pad. Ribs on the walls of the cavity slide between the pins to separate and straighten any bent pins. The retaining clip includes four downwardly bent flat springs connected in a rectangular pattern. Four slots in the housing extend vertically between the top thereof and the bottom of the fingers. Hooks projecting from the comers of the clip are positioned through the slots. The tips of the hooks extend out the bottom of the fingers and engage the bottom rims of the registration holes. The clip-on IC retaining apparatus and the IC can be easily installed as necessary by a user anytime after the circuit board is manufactured.
