Abstract

PURPOSE:To achieve the high reliability of the apparatus by a method wherein the electric current of a simultaneous ignition type ignitor for internal combustion engine use is made satisfactorily large. CONSTITUTION:Two power transistors 3 are soldered and bonded to an insulating board 2; this laminated body is soldered and bonded to an aluminum or copper base. In order to make an electric current large in the future, two Ni wires are welded so that the allowable current of an Ni wire of 10 A is not exceeded even when double chips are turned on simultaneously and a large electric current flows through a conductor resistor 5 on a hybrid IC substrate 4. The electric current of an ignitor can be made large (15 A). As a result, it is possible to supply an ignition system whose ignition coil can be made small-sized and which is excellent in engine characteristics.

One Ni wire and one Ni wire were welded to the conductor resistance on the HyIC substrate on the welding pad, respectively. Generally, the maximum current that can be passed through one Ni wire is 10 amps. Therefore, in the present technology, a maximum of 20 amps can be flown by mounting a double power transistor, and accordingly, two Ni wires are welded. This is a measure against the possibility that the input signal of the igniter may turn ON at the same time, which may occur accidentally, and is not a mode that normally occurs. In this mode, the conductor resistance on the HyIC substrate is obtained by applying the conventional technique (described later).

Two Ni wires are welded to one conductor resistance on the substrate. In addition, the number of conductor resistances, which was three or two in the past, was combined into one, and it is used as a countermeasure when all the input signals of the igniter that are accidentally turned on simultaneously.
This is a system in which only one conductor resistance flows when all of them are turned on at the same time, so that only a current determined by the conductor resistance flows. Further, the external terminal is formed into a terminal shape having a better weldability by widening the portion where two Ni wires are welded.

In the power transistor of the igniter, heat is generated from the junction portion due to the switching operation of turning on / off the primary current of the ignition coil. This time, the amount of heat generated by mounting two power transistor chips on one insulating plate is also doubled. In order to dissipate this amount of heat, the power transistor employs laminated heat dissipation. In this laminated state, if the insulating plates are AlN, they are directly solder-bonded, and if they are Al 2 O 3, they are solder-bonded via a Mo plate. Solder the laminate to an aluminum or copper base. Furthermore, since there is only one conductor resistance on the HyIC substrate, for example, if the resistance value is determined by laser trimming so that only 15 amperes flow to the conductor resistance, only 15 amperes will flow to the conductor resistance. For each book, two Ni wires may be welded through the welding pad. Further, the purpose can be achieved by welding two Ni wires to the laminated body through a welding pad.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The ignition coil 14 has a primary winding 11 and a secondary winding 12, and one of the primary winding 11 is a current from a battery and the other is a power switching element 3 (Darlington transistor type) for driving an ignition coil. And MOS-FET type). In addition, the ignition coil 14 of the 2
The secondary voltage generated in the secondary winding 12 is the spark plug 13
Be led to. The ignition device (igniter) shown in FIG.
This is an example of a cylinder ignition type igniter, in which a power switching element (power transistor chip) 3 is soldered onto an insulating plate (AlN or Al 2 O 3 ). At this time, two (double) power transistor chips 3 are mounted on the insulating plate 2. Since the power transistor chip 3 has a permissible current of 10 amps, mounting the two power transistor chips 3 increases the permissible current to 20 amps. Further, in order to cope with the current up to 20 amperes, the collector terminal 8 and the welding pad 15 are wiped with two Ni wires 6. Generally, since the permissible current of the Ni wire 6 is 10 amperes, the countermeasure is 20 amperes. Therefore, even if the input signals of the igniter 1 are turned on at the same time, the Ni wire 6 will not be blown. The laminated body of the insulating plates 2 is soldered to an aluminum or copper base, and the HyIC substrate 4 is bonded to the aluminum or copper base with a silicon adhesive. At this time, the HyIC substrate 4 adjusts the current limiting value to about 15 amps with one conductor resistor 5. Therefore, even if the power transistor 3 having a large current is accidentally turned on at the same time, the current is limited by the conductor resistance 5, and the conductor resistance 5 is welded through the welding pad 15 and the two Ni wires 6 are welded. By doing so, the Ni wire 6 does not melt. At this time, the GND terminal 9 and the collector terminal 8 to which the two wires 6 are welded are wider terminals than usual. When the simultaneous ON is accidentally generated, a signal indicating that all the cylinders are ON is transmitted from the base terminal 10 through the Ni wire 6 to the HyIC substrate 4. The signal is transmitted through the aluminum wire 7 to switch the power transistor 3, and a large current flows from the collector terminal 8. 6 in FIG.
When all the cylinders are turned on, about 20 amps x 3 laminated body =
It has a capacity of 60 amperes, but since the conductor resistance 5 is current-limited and has only one, only a current of about 15 amperes, determined by the conductor resistance, flows in. As a result, the current value of the simultaneous ignition type igniter is greatly increased, and by supplying an ideal secondary voltage to the engine, it has excellent torque characteristics and output characteristics. It is possible to supply an engine with highly reliable and always stable sparks by achieving an improvement in consumption rate).
