を形成する例えばＡｌ１線等のワイヤーを示している。Conventional technology and its problems In recent years, the demand for electronic devices to be smaller, lighter, faster, and more reliable has increased significantly.In order to satisfy these demands, for example, alumina ceramic plates have been The so-called thick film wiring board method is used to give a specific circuit function by repeatedly printing, drying, and baking conductive paste and insulating paste, and laminating them, or by repeatedly laminating conductive paste and insulating paste in a dry state on a green sheet. After that, we use the so-called printed laminated metallized ceramic substrate method to give specific circuit functions by co-firing in a reducing atmosphere furnace, or we form through holes in the green sheet by punching a mold, and then apply conductive paste on top of it. It is formed by the so-called sheet lamination method, etc., which prints, dries, stacks multiple green sheets, pressurizes them, and then simultaneously fires them in a reducing atmosphere furnace to give them a specific circuit function. A so-called multi-chip packaging technology is being developed in which multiple chip components such as IC chips are mounted on a wiring board and the whole is hermetically sealed.The external structure of such a multi-chip package is as follows.
As shown in FIG. 1, a high-density wiring board 1-1 and a base 1-2 such as a cap are supported and fixed on the wiring board 1-1 by, for example, soldering or welding 4 in order to hermetically seal the whole. , and input/output terminals 1-3 formed on the periphery of the wiring board 1-1 by, for example, soldering or silver brazing. In the figure, 1-4 shows an IC chip which is an electronic functional element, 1-5id also shows a capacitor chip, and l-6 shows the connection between the IC chip 1-5 and the wiring board l-1. A wire, for example an Al1 wire, is shown forming the electrical connection.

成すすべも無かった。Here, 2-1 indicates a wiring board for a multi-chip package, and 2-2 indicates a base such as a hermetic sealing cap. However, in this method, only one system to be formed is incorporated. There is no problem if the planar area of the base such as the casing is large enough to mount a plurality of the multi-chip packages (Fig. 1), but if the planar area of the base such as the casing is If there is only an area that is approximately the same as the planar area of a multi-chip package (Figure 1), it is extremely difficult to mount multiple multi-chip packages within a base such as a casing9.

得るであろう。Embodiment of the Invention An embodiment of the present invention will be described below with reference to the drawings. 3rd IQ ((a) top view, (b) side view) shows the structure of the multi-chip package according to the present invention, 3-1 is a mountain: chip components such as IC chips that are reserved functional elements are The wiring board 3-2 to be supported and fixed is placed on the wiring board 3-1 in order to hermetically seal the entire chip components.
・Additional methods such as soldering or welding:
1z is shown for a base such as a cap. 3-3 indicates an input/output terminal formed outward parallel to the chip component mounting surface of the multi-chip cage by a method such as soldering or silver soldering. The cloth plate 3-4 is formed at at least two places (four places in the figure) on the wiring board 3-1 around the base body 3-2, such as a cap formed for airtight sealing according to the present invention. It shows a through hole. FIG. 4 ((a) is a plan view, (b) is a side view) shows a resin block made of, for example, Teflon, which has some elasticity so as not to damage the wiring board 3-1 according to the present invention. A through hole 4-1, which is approximately the same size as the through hole 3-4 formed at the periphery of the wiring board 3-1, is formed in the resin block such as Teflon. FIG. 5 shows a multi-chip package (third chip package) according to the present invention.
FIG. 4 is a side view showing a mounting method in which the device shown in FIG. That is, at least two or more through holes are provided in the periphery of the multi-chip package between each of the first multi-chip package to the N-th multi-chip package and between the N-th multi-chip package and the housing. Align the through hole 4-1 of the resin block 5-5 made of Teflon or the like with the position where the resin block 3-4 exists, and insert the resin block 5-5 made of Teflon or the like (Fig. 4),
Insert a rigid rod 5-6 made of metal or the like that allows light to pass through these through holes and the plurality of 3-4 and 4-1, and attach the tip of the rod 5-6 to a base such as a casing by screwing or other methods. By supporting and fixing to 5-7, it became possible to efficiently mount the first to Nth multi-chip packages. 5-1 is a wiring board of the multi-chip package, 5-2 is a base such as a cap formed for airtight sealing, and 5-3 is an input/output terminal of the multi-chip package. Reference numeral 5-8 indicates a bolt in which the tip of the rigid rod made of metal or the like is screwed, for example, with a bolt. Here, the method for forming electrical connections between the input/output terminals 5-3 of each of the first to Nth multi-chip packages is to simply solder metal wires etc. without causing short-circuit accidents. However, for example, through holes may be provided in advance in a flexible wiring board (flexible printed wiring board) at the positions where the input/output terminals 5-3 of each multi-chip package exist, and each predetermined input/output terminal 5-3, and insert the sinterable wiring board (flexible printed wiring board) into the input/output terminal 5-3 of the multi-chip package.
If the multi-chip package is supported and fixed by a method such as soldering and electrical connection is formed, electrical connection between the input and output terminals 5-3 of each multi-chip package can be formed more easily and with high reliability.
