Abstract

An insulating unit having a neutral grey color and a solar heat gain coefficient less than 0. 40 includes a clear glass sheet spaced from a coated glass sheet. The coated glass sheet includes a colored glass substrate having a solar infrared reflective coating. The composition of the coated substrate includes a base glass portion and a glass colorant portion, the glass colorant portion including total iron in the range of 0. 04 to less than 0. 28 weight percent; CoO in the range of 32 to 90 parts per million, and Se in the range of greater than 0 to less than 5. 5 parts per million. In one non-limiting embodiment of the invention the glass substrate at a thickness of 0. 223 inches has a* chromaticity coordinates of −3. 5 to +2. 5 and b* chromaticity coordinates of −1 to −15, and a visible light transmittance of 40 to 80%.

Abstract

An improved omni-directional non-occluding solder pad design for printed circuit boards comprising a plurality of spokes radiating outward from a through-hole on the printed circuit board, with a ring concentric to the through-hole that intersects each of the plurality of spokes at approximately a perpendicular angle. The ringed-spoke configuration eliminates the need to ensure proper orientation of the solder pad on the printed circuit board prior to a wave soldering process since the symmetrical ringed-spoke design is omni-directional. The concentric ring structure provides an additional contact area of solder between the printed circuit board and a computer chassis. This additional contact area of solder ensures that there is a sufficient electrical connection between the printed circuit board and the computer chassis such that when the printed circuit board is mounted to the computer chassis, a proper grounding connection is provided.
