ABSTRACT:
An I/O card assembly (10) includes a rectangular frame (12) having an internal PC board (100) therein and sandwiched between a pair of metal covers (11, 14). A pair of connectors (22, 24) are respectively positioned on two opposite ends of the I/O card assembly (10) wherein one connector (22) has contact tails solderably mounted onto the circuit pads (102) on one end of the PC board (100), and the other connector (24) has contact tails solderably mounted onto the circuit pads on the other end of the PC board (100). The frame (12) includes recesses (13) to retainably receive the mounting ears (32) of the connectors (22) therein so that the connector (22) can be retained within the frame (12) in position. The PC board (100) is made from a raw plate (106) which includes holes (104) therein to receivably retain boardlock means (34) therein so that the connector (22) can be directly but temporarily retained, i.e., not permanently fixed, with regard to the PC board (100) before the contact tails (30) have been permanently soldered onto the corresponding circuit pads (102) of the PC board (100). Therefore, such temporary retention between the connector (22) and the PC board (100) may preclude the connector (22) from misplacement with regard to the PC board (100) by any inadvertent impact before soldering, and assure the reliable and correct mountable connection or engagement between the connector (22) and the PC board (100) in a later reflow soldering process.
