Abstract

PURPOSE:To effectively perform electric welding by providing a projection on the outer peripheral edge of a metal frame provided at the peripheral edge of a ceramic board. CONSTITUTION:A projection 10a is formed at the outer peripheral edge of a metal frame 10 brazed to the peripheral edge of a ceramic board 3 as a package member. A roller electrode 7 is pressed to a contacting portion of the projection 10a with a metal cap 1 while rotating the electrode 7, and a current is supplied to between the electrodes. Since Joule heat is generated almost at the contact of the projection 10a, even if the current is less, sufficient brazing strength can be obtained. Thus, a welding of good current efficiency can be performed.

C. Is the ceramic having a metal frame 2 soldered with a brazing material etc. a base plate 3 and a metal cap 1? prepare. After adhering the ten-layer chip 4 to the recess of the ceramic substrate 6 and making electrical connection with the external lead 6 using the bonding wire 5, the metal cap 1 is placed on the all-metal frame 2. Then, while both are pressed together from above with a pair of roller electrodes 7, a full wave of current is applied between the electrodes, and the Joule heat generated is used to weld. This hermetic sealing has the advantage that the semiconductor chip 4 is not heated during welding.

In the above-mentioned welding method, a large amount of current flows to the cap other than the welded part, and the current efficiency is not good, so accidents of poor bath coal often occur. In order to prevent this, if a large amount of water is passed through the cap, problems such as discoloration of the cap due to overheating will occur. The range of current conditions that would normally achieve complete hermetic sealing was narrow, and it was difficult to set the conditions while taking into account variations in the material and shape of the package.

If the cap is made thinner, the proportion of the current component in the cap's full wave will be reduced, and the contact flow can be made smaller. The cap is deformed. The deformation not only causes the product to look defective, but also causes defects in which the characters are not stamped properly.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram for explaining one embodiment. As a package member, a metal frame 10 is soldered to the periphery of the ceramic substrate 3.Protrusions 10a are provided on the outer periphery as shown in the figure.
It has f.

All sealing work is carried out as before. While rotating, the roller electrode 7' is pressed against the entire contact area between the protrusion 10a and the metal cap 1, and a current is passed between the electrodes. Most of the Joule heat is generated at the contact 7 of the protrusion 10a! ! Therefore, sufficient soldering strength can be obtained even with a small current.

Next, as a second example, a case will be described in which the structure of the electrode is changed. As shown in FIG. 2, the t-pole 11 on the trill side
A contacts the metal frame 10 from above, and the other electrode 11B contacts the metal frame 10 from the side. The current from the electrode 11A passes through the periphery of the Daishu cag 1,
Flows through the protrusion 10a of o and 1. to the pole 11B.This four-electrode structure has the advantage that the entire outer circumference can be brought into contact with the bath at the same time, which reduces the working time, compared to the case of the conventional rotating RL pole.
Also, the current flowing through the metal cap 1 is exactly the protrusion 10aiC.
The cap thickness Vi does not affect the current efficiency because the current flows only in the bath contact area. Therefore, the thickness of the cap can be set to a desired thickness with full consideration of mechanical strength.

As explained above, in the package of the present invention, current is concentrated on the protruding part of the metal frame provided at the periphery of the ceramic base and welding is performed at this part, so welding can be performed with high current efficiency. . Therefore, is the current efficiency as low as in the past? In order to cover this, the current value is increased to avoid the accident of overheating and discoloration of the Sea C cap.
