    Abstract: A circuit board for heat dispersion includes a rectangle dielectric layer (10) and a plurality of pad groups (1, 2, 3) for soldering an electronic element. The pad groups (1, 2, 3) are laid on the front surface of the dielectric layer (10). Each pad group comprises a plurality of metal conductive pads (11, 12, 13), (21, 22, 23), (31, 32, 33) which are arranged at intervals. There is a first transverse insulating isolated area (6) between the two adjacent pads (11, 12), (12, 13), (21, 22), (22, 23), (31, 32), (32, 33). The width of the insulating isolated area (6) is less than the span between the positive terminal solder area and the negative terminal solder area of the electronic component. There are an anode soldering sheet (7) and a cathode soldering sheet (8) on the back surface of the dielectric layer (10). The anode soldering sheet (7) and cathode soldering sheet (8) spread on the back surface of the dielectric layer (10). There is a second insulating isolated area (9) between the anode soldering sheet (7) and the cathode soldering sheet (8). The first pad (11, 21, 31) and the last pad (13, 23, 33) of each pad group have vias (111, 131), (211, 231), (311, 331). The wall of the vias have conductive plating layer. The plating layer connects the pads to the anode soldering sheet (7) or the cathode soldering sheet (8).

    Abstract: PROBLEM TO BE SOLVED: To effectively reduce noises produced by the switching action of a driving circuit in an electronic controller. SOLUTION: In an electronic controller having a charge pump circuit 45, a dedicated power wiring 1 and a power wiring 3 common to each circuit are connected to the charge pump circuit 45 through a via hole va whose impedance is larger than that of the wiring pattern, and similarly, a dedicated ground wiring 5 and a ground wiring 7 common to each circuit are connected to the circuit 45 through a via hole vb. Further, a condenser C for controlling noise production is connected between a power wiring 2 connecting the via hole va and the power wiring 1, and a ground wiring 6 connecting the via hole vb and the ground wiring 5. Accordingly, a sharp current variation is surely prevented from being produced to the common power wiring 3 and the ground wiring 7 by the switching action of switching devices 12 and 13 of the circuit 45.
