With recent miniaturization of the lead wire pitch and increase in the number of pins, the strength of the lead wire per wire is also reduced. As a result, for example, the lead wire is likely to be deformed at the time of transportation, and a countermeasure is required. The present invention relates to a technique for preventing such lead wire deformation.

Description of the Related Art Conventionally, in this type of package, as shown in FIG. 5, individual leads 11 (pins) extending in four directions from a main body 10 are independent from each other, and bending occurs for each single pin. was there. Therefore, for example, as shown in FIG. 6, it has been proposed that a rectangular support frame 13 be sandwiched between the peripheral edges of the frame and adhered to each other, and the support frame 13 is conveyed or tested for performance in this state. The frame also serves as a positioning guide during performance testing.

It is necessary to cut off the lead wire and to further bend the lead (note that in FIG. 7, only a part of the lead wire is enlarged). Further, in the performance test, the central part of each lead wire is not preferable because it becomes a connection part. This is because the contact becomes unstable in the method of bringing the contactor of the tester into contact with the central portion of the lead wire. Therefore, conventionally, preferably, the performance test is generally performed using the bottom surface of the end portion of the lead wire as the connection portion.

To provide. In order to achieve the above object, according to the present invention, in a semiconductor package having a package main body and a large number of lead wires extending from the package main body, a protective film covering the lead wires is attached to the end portions of the lead wires. The protective film is characterized in that it is formed of a material that is softened by the heat of the lead wire when it is joined by solder and is fused to the lead wire.

行なえば、ユーザサイドでの曲げ作業は不要である。According to the above construction, the lead wires are integrally joined by attaching a protective film on the upper surface of the end portions of the lead wires instead of the conventional support frame, so that they are subjected to mechanical shock or the like. Bending is less likely to occur, and the bottom surface of the end of the lead wire remains exposed, so it can be used as it is, for example, as a connection portion during a performance test. By forming the protective film with a material that is softened by heat, the protective film is melted by the solder melting heat when the lead wire is mounted on the printed board, and therefore, the work of removing the protective film is unnecessary. Also,
If the attachment of the protective film is performed after bending the lead wire (pin), the bending work on the user side is unnecessary.

The parts corresponding to those shown in FIG. 5 and subsequent figures explained above are given the same part numbers, and duplicate explanations thereof are omitted. In the present invention, preferably, the end portion bending process of the lead wire 11 required before shipping to the user is completed in advance as shown in FIG. After that, a protective film 15 having a shape as shown in FIG. 4 is adhered to the upper surface around the end of the bent lead wire 11 with an adhesive (not shown) or the like. The protective film 15 has a substantially rectangular shape in which a portion corresponding to the semiconductor package body 10 is hollowed out, and the shape thereof is appropriately determined according to the shapes of the semiconductor package body 10 and the lead wire 11.

い。The semiconductor package is finally mounted on the printed board 20 (FIG. 3), and at this time, the bottom surface of the lead wire 11 is soldered to the corresponding conductor pattern of the printed board 20. Therefore, the protective film 15 is formed of a material that is softened, melted, and evaporated by the heat during the soldering work. By doing so, the work of removing the protective film 15 from time to time becomes unnecessary. Further, if it is a material that melts even if it does not evaporate, it contributes as an adhesive and there is no functional difference from the conventional one.

7 can be provided. That is, by aligning the corresponding holes 18 formed in the semiconductor body 10 with the holes 17 of the protective film 15, the positions of the two can be surely aligned. When the protective film 15 does not have a specific directionality in relation to the semiconductor body 10, the alignment hole 17 is naturally unnecessary. Similarly, when it is necessary to specify the directionality with respect to the printed board 20 (FIG. 3), for example, a notch 21 (FIGS. 2 and 4) is provided at one corner of the protective film 15.
Positioning can be done easily by forming.
