部の実装密度に対してモジュール全体でみた場合の実装
密度は低くなるという欠点があった。Sealing is performed to isolate wiring, etc. from the outside and prevent metal corrosion. In the figure, 5 is a metal cap for sealing, and 42 alloy or Kovar is usually used. This cap 5 is soldered onto the metallization 2 applied on the circumference of the substrate surface using solder, ALLSn silver solder, or the like. FIG. 2 shows another conventional example, in which a metal flange 7 is used for sealing, holding a cooling body, or as a means for attaching the entire module. It is attached to the back side of the ceramic substrate 1. As can be seen in the figure, in the conventional example, the metallization to be brazed is located on the main plane of the wiring board. As a result, the chip mounting area is reduced in the example shown in Fig. 1, and the input/output pin area is reduced in the example shown in Fig. 2, and the external flange 7 prevents dense mounting on this hybrid ICf motherboard. . Therefore, the conventional example has a drawback that the packaging density of the entire module is lower than the packaging density of the chip mounting section.

したことを特徴とする。In order to achieve all of the above objects, the present invention is characterized in that metallization is applied not to the main plane of the wiring board, but to the end face, so that it can be used for brazing for sealing, etc., without reducing the density. do.
第３図に本発明の一実施例の断面図を示す。 FIG. 3 shows a sectional view of an embodiment of the present invention.

も濡れてフィレットを形成している。As shown in the figure, the sealing metallization 2 is applied to the end surface of the wiring board 1 and soldered to the metal cap 5 using a brazing material 6. An enlarged view of the soldered part is shown in Fig. 4. In this figure, the brazing material wets the soldered end face and also wets the metal cap 5, forming a fillet.

に比較して、ろう接面積が増し、かつ、基板１に対する
ろう材の濡れ角度を小さくできるため、ろう接の強度。FIG. 5 is an enlarged sectional view of another embodiment of the invention. Here, the metallization 2 is provided not only on the end face but also on the main plane in contact with the end face. As a result, compared to the one shown in FIG. 4, the soldering area is increased and the wetting angle of the brazing material with respect to the substrate 1 can be made smaller, thereby increasing the strength of the soldering.
信頼性の向上をはかることができる。Reliability can be improved.

ズ２Ｆｉ、第８図に示すように基板１の通常四辺にそっ
て等巾で形成される。FIGS. 6 and 7 each show an example in which metallization 2 is applied only to one periphery of the main plane. Incidentally, the metallization 2Fi around these is generally formed with the same width along the four sides of the substrate 1, as shown in FIG.
このように、本実施例では、ろう接のための主たる部分

比は、（１１０／１００）２＝１．２１ 、すなわち２
１％も大きくなる。In this way, in this embodiment, since the main part for soldering is the end face of the board, a large area of the main plane of the board is not taken up for the soldering part, and as a result, the size can be reduced compared to the conventional one. It becomes possible. For example, if a 10cm square board is made louder by 5M width for brazing, the area ratio is (110/100)2=1.21, that is, 2
It will increase by 1%.
これに対し、基板の（例えば５Ｍ厚の）端面を利用する

従来例より小型になる効果は、基板の製造歩留り、材料
コストにも有利となる。On the other hand, if the end face of the board (for example, 5M thick) is used, the size of the wiring board does not change at all. Furthermore, the effect of making the substrate smaller than the conventional example is advantageous in terms of manufacturing yield and material cost of the substrate.

同様の効果を有する。The above embodiment describes the case where the sealing cap is brazed directly to the board, but it is also possible to attach a sealing O-ring, a cooling structure, or a flange for mounting a module. Also when brazing
Has a similar effect.

減、製造歩留向上に寄与することができる。As described above, according to the present invention, since the end face of the substrate is effectively utilized, the size of the substrate can be reduced compared to the conventional method. Therefore, it is possible to contribute to an effective increase in packaging density, a reduction in substrate material costs, and an improvement in manufacturing yield.
