供するものである。The present invention has been made in consideration of the above-mentioned problems, and includes a band-shaped etching sheet in which punched patterns of lead frames, electronic components, etc. formed by etching are arranged on multiple sides, and a frame portion around the punched patterns is provided. The present invention provides a band-shaped etched sheet characterized by having a flexible portion. Furthermore, when etching a band-shaped metal sheet in a predetermined pattern to produce a band-shaped etched sheet having a punching pattern for multi-faceted lead frames, electronic components, etc., when etching the punching pattern, a frame surrounding the punching pattern is formed. The present invention provides a method for manufacturing a band-shaped etched sheet, characterized in that the frame portion is also etched, and a flexible portion is provided in the frame portion by the etching.

つぎに、本発明を第１図から第３図に示す実施例に基づ
いて詳細に説明する。In the present invention, by providing a flexible portion in the frame portion, the frame portion becomes soft, and when moving on the rollers, the punched pattern side does not undergo large deformation and the whole deforms in a continuous state. It becomes like this. Further, the frame portion is etched together with the etching of the punching pattern, so that the flexible portion is formed at the same time as the punching pattern. This will be explained in detail based on the following.
すなわち本発明においては、帯状エツチングシート３の
多面付された抜きパターン２周囲の枠部５に柔弱部６を
設け、前記枠部５の堅さを小さくして抜きパターン２と

グシート３が移動するとき、前記枠部５も同様に変形し
、抜きパターン２の枠部近傍側に大きな変形を生じさせ
ることがない。That is, in the present invention, a flexible portion 6 is provided in the frame portion 5 around the multi-faceted punching pattern 2 of the strip-shaped etching sheet 3, and the stiffness of the frame portion 5 is reduced to form a pattern similar to the punching pattern 2. The softness is such that the punched pattern 2 will not be deformed. Due to these, when the band-shaped etched sheet 3 moves on the roller 4 as shown in FIG. 2, the frame portion 5 is also deformed, and the side near the frame portion of the punching pattern 2 is not significantly deformed. .
そして柔弱部６を設けるに当たっては、抜きパターン２
を得るためのエツチングと同時に所定のエツチングによ

れる。When forming the soft portion 6, the punching pattern 2
It is formed by a predetermined etching at the same time as the etching to obtain the pattern, and can be obtained in the same process without using a separate process.
上記柔弱部６は、第１図に示すように、複数個の矩形状

る。As shown in FIG. 1, the flexible portion 6 may be configured by arranging a plurality of rectangular through holes 7, or may be formed as a slit-like through hole, a long hole, or a mesh cane. can also be configured,
Depending on the etching pattern, the cane can be made into an appropriate shape.

In the case of this thin part, it is possible to provide it by performing half etching from one side of the frame part, or to provide it by shifting its position from the front and back good sides.

Since the flexible part is provided, the frame part becomes flexible, so that the whole part deforms in a continuous state even when moving through the roller after etching.
Large deformation does not occur in the vicinity of the frame of the punched pattern, and the occurrence of defects can be easily suppressed.

ど、実用性にすぐれた効果を奏するものである。Furthermore, when etching a band-shaped metal sheet in a predetermined pattern to produce a band-shaped etched sheet having a punching pattern for multi-faceted lead frames, electronic components, etc., when etching the punching pattern, a frame surrounding the punching pattern is formed. Since the etching is also applied to the frame part and a soft part is formed in the frame part, there is no need for a separate process. This makes it possible to easily produce a useful strip-shaped etched sheet as described in item 1 without increasing costs, and has excellent practical effects.
