Abstract

In the wave soldering of printed circuit cards having precious metal tabs for insertion into connectors, it is critical that the solder not splash on the tabs because when the card is plugged into the connector, springs wipe against the tabs to make an electrical connection. If solder is splashed on the tabs, it would jeopardize the electrical connection. A splash shield that prevents solder splash is constructed and works as described in the following. As seen in the drawing, the splash shield 1 consists of an upper jaw 2 that is constructed of two pieces of angled titanium 3, 4 that are spot-welded together. The two titanium pieces 3, 4 have a rubber seal 5 between them. A bottom jaw 6 is similarly constructed of two titanium pieces 7, 8 that are spot-welded together and hold a rubber seal 9.

Splash Shield

In the wave soldering of printed circuit cards having precious metal tabs for insertion into connectors, it is critical that the solder not splash on the tabs because when the card is plugged into the connector, springs wipe against the tabs to make an electrical connection. If solder is splashed on the tabs, it would jeopardize the electrical connection. A splash shield that prevents solder splash is constructed and works as described in the following. As seen in the drawing, the splash shield 1 consists of an upper jaw 2 that is constructed of two pieces of angled titanium 3, 4 that are spot-welded together. The two titanium pieces 3, 4 have a rubber seal 5 between them. A bottom jaw 6 is similarly constructed of two titanium pieces 7, 8 that are spot-welded together and hold a rubber seal 9. The upper jaw 2 is joined to the lower jaw 6 by a pinned hinge 10. The rubber seals 5, 9 are held between the angled pieces 3, 4, 7, 8 by high temperature silicon rubber. The splash shield 1 affixes to a circuit card 11 by inserting the hinge 10 into a slot (not seen) on the side of the card 11 and closing the upper jaw 2 and lower jaw 6 of the shield 1. The shield 1 is held in the closed position by a pin (not seen) on the back of piece 7 that fits into hole 12 on the upper jaw
2. The pin has a shoulder to keep jaws closed. When the shield is closed, the rubber seals 5, 9 form a tight fit to prevent solder from splashing on the tabs 13 of the card 11. After...
