20080238584 | Reducing crosstalk in electronic devices having microstrip lines - An electronic device may be formed of a printed circuit board having integrated circuits mounted thereon. A backing plate may compress an insulating layer against a microstrip line formed on one surface of said circuit board opposite to the surface that includes integrated circuits. By compressing said backing plate against said insulating layer, less crosstalk may result from the formation of a microstrip on the bottom surface of the printed circuit board. The backing plate may also be used to secure a cooling device, such as a heat sink, on the opposite side of the circuit board. | 10-02-2008 |
20080314620 | Skew Compensation by Changing Ground Parasitic For Traces - According to embodiments, small holes or openings may be cut on or through the ground plane(s) adjacent to a selected trace line, so that C and L will be changed accordingly. Then phase velocity will also be changed. As a result, the flying time from one location or point to a different location or point of the transmission line will also be changed. This concept applies to a single trace. Similarly, this concept may be applied to one trace of a differential pair of traces (e.g., so that the two parts of the differential signal transmitted at one point in time at a location on the pair arrive at the same time at another location of the pair). | 12-25-2008 |
