Abstract: A connecting device for connecting pins of a DIP chip to a test device comprises two each of half frames, columns of testing pins, connecting screws, fixing screws, and four holding plates. The two columns of testing pins are arranged respectively on the two half frames parallel to the lengthways direction of the half frame. The distance between two adjacent testing pins in the same column is equal to that between the two adjacent pins in the same column of the DIP chip. The two connecting screws screw into the half frames perpendicular to the lengthways direction of the half frame. Two of the holding plates extend down from each of the half frames and are aligned with short sides of the corresponding half frame. The fixing screws fix the two holding plates on the same half frame along a direction parallel to the lengthways direction of the half frame.

Abstract: A circuit for controlling a rotation speed of a computer fan includes a control chip, a conversion circuit, a fan header, a first switch, and a second switch. When a first terminal of the first switch is connected to a second terminal of the first switch, and a first terminal of the second switch is connected to a second terminal of the second switch, the conversion circuit converts a control signal received from the control chip to a voltage signal, and outputs the voltage signal to a power pin of the fan header. When the first terminal of the first switch is connected to a third terminal of the first switch, and the first terminal of the second switch is connected to a third terminal of the second switch, a control pin of the fan header receives the control signal, the power pin receives power from a first power supply.

Abstract: A layout method of a differential pair generates the differential pair between a differential signal sender and a differential signal receiver in a printed circuit board (PCB). Differential signal is transmitted via two wires. A plurality of vertical lines are created at a breakout section and a trace section of the differential pair. Junctions of the vertical lines and the two wires are defined as pair of points. A first distance between one pin of the differential signal sender and a corresponding point of each pair of points and a second distance between the other pin of the differential signal sender and the other corresponding point of each pair of points are calculated. If a difference between the first distance and the second distance does not fall within an allowable range, the two wires are adjusted.
