Abstract: A printed circuit board includes a reference layer configured to connect to a power or a ground and a dielectric layer stacked on the reference layer. The dielectric layer includes a component surface opposing the reference layer. The component surface forms a differential pairs, a protection runner, and a power runner. The differential pairs include a substantially linear part. The protection runner is intervened between the linear part and the power runner, and is substantially parallel to the differential pairs. The length of the protection runner is approximately equal to that of the linear part. Each of the two ends of the protection runner forms a via that electrically connects the protection runner to the reference layer.

Abstract: A differential circuit includes a chip with two terminals in two directions, a first differential signal trace, and a second differential signal trace. The first differential signal trace includes a first parallel section and a first unparallel section connecting the first parallel section to a terminal of the chip. The second differential signal trace includes a second parallel section parallel to the first parallel section, a second unparallel section connecting to the second parallel section, and an equalizing section connecting second unparallel section to the another terminal of the chip. The second parallel section is equal to the first parallel section. The total length of the second unparallel section and the equalizing section is equal to the length of the first unparallel section.

Abstract: A test apparatus includes a circuit board and an expansion slot. A number of golden fingers are arranged on a first side of the circuit board. A second side of the circuit board is connected to a bottom of the expansion slot. The golden fingers are electrically connected to the expansion slot. A number of first test pads and second test pads are arranged on the circuit board between the first side and the second side. The first and second test pads have different shapes, sizes, and/or colors. The first and second test pads are electrically connected to pins in the expansion slot.
