Abstract

A circuit card carrier provides protection for the gold tabs of a circuit card. The carrier is designed to protect the gold tabs from damage caused by both contact and static electrical discharge. The card 1 has a small notch 2 that is first hooked over the catch 3 on the carrier 4 to secure the card 1 to the carrier 4 on one side. The card 1 is then pushed in the direction indicated by the arrow 5 until the large notch 6 is fully engaged by the spring clip 7. The gold tab 8 is now completely protected by the carrier 1. The carrier 4 is designed to maximize the cleaning of the gold tab 8. The clearance 9 (Fig. 2) around the gold tab 8 and the slots 12 (Fig. 1) on the bottom of the carrier are both features to facilitate the easy cleaning of the gold tab 8.

Card-Protective Carrier

A circuit card carrier provides protection for the gold tabs of a circuit card. The carrier is designed to protect the gold tabs from damage caused by both contact and static electrical discharge. The card 1 has a small notch 2 that is first hooked over the catch 3 on the carrier 4 to secure the card 1 to the carrier 4 on one side. The card 1 is then pushed in the direction indicated by the arrow 5 until the large notch 6 is fully engaged by the spring clip 7. The gold tab 8 is now completely protected by the carrier 1. The carrier 4 is designed to maximize the cleaning of the gold tab 8. The clearance 9 (Fig. 2) around the gold tab 8 and the slots 12 (Fig. 1) on the bottom of the carrier are both features to facilitate the easy cleaning of the gold tab 8. The card carrier 4 does not interfere with any subsequent operation, i.e., soldering, etc. To remove the card 1 from the carrier 4, a special tool 10 (Fig. 3) is inserted and actuated in the direction of the arrow 11 to depress the spring clip 7 to clear the large notch 6. The card is then pulled out of the carrier 4. The protective carrier 4 is made from polymer plastic having high temperature resistance and good chemical resistance to the chemicals used in various processes (i.e., solder flux, cleaning solvent, etc.). The material is also static conductive. The card 1 is held in place by a metal clip 7 which is assembled on the plastic carrier 4 after the carrier is molded.
