Abstract

PURPOSE:To obtain a circuit module which does not induce pattern burn-out due to stress in assembly, etc., by providing a pattern which is to related to a signal line at a flexible printed-circuit board and that which is hot related to the signal line at a printed-circuit board of a circuit module opposing it, and then soldering the patterns. CONSTITUTION:Corresponding signal lines of signal line patterns 3 are soldered on a printed-circuit board 1 and a flexible circuit board 2. Further, patterns 4 which are not related to the signal line are also soldered. The patterns which are not related to the signal line are located at an inside from a part which is exposed form a protection film 5 of the signal line pattern 3. When the flexible printed-circuit board 2 is soldered onto the printed-circuit board 1, soldering of the signal line pattern is made at an inside from the printed-circuit board end face as compared with soldering of a pattern which is not related to the signal line. Therefore, if a stress is applied in a direction for releasing the flexible printed-circuit board 2 from the printed-circuit board 1, stress is applied to a part to be soldered of the pattern 4 which is not related to the signal line and no stress is applied to the part to be soldered of the signal line pattern 3.

[Problem to be Solved by the Invention] In the conventional circuit module having a flexible board for connection with another circuit board, only the signal line pattern is soldered, so it is difficult to connect and assemble it to another circuit board. At times, stress is applied to the soldered portion, causing pattern breakage. SUMMARY OF THE INVENTION An object of the present invention is to solve this problem and provide a circuit module that does not cause pattern disconnection even under stress during assembly.

[Embodiment] A perspective view of an embodiment according to the present invention is shown in FIG. 1. 1 is a circuit board, 2 is a lexical board, 5 is a signal line pattern, 4
is a pattern unrelated to signal lines. For the signal line patterns 6 on the circuit board 1 and the flexible board 2, corresponding signal lines are soldered to each other. Furthermore, patterns 4 unrelated to the signal lines on the circuit board 1 and the flexible board 2 are also soldered. FIG. 2 is a plan view of the flexible board soldering portion of the circuit board 1. FIG. The end surface of the pattern 4, which has no relation to the signal line, is closer to the outer edge than the signal line pattern 5. Further, FIG. 3 is a plan view of the circuit board soldering portion of the flexible board 20. 5 is a protective film. The pattern 4 unrelated to the signal line is located inside the portion of the signal line pattern 3 exposed from the protective film 5. When this flexible board 2 is soldered to the circuit board 1, the soldering of the signal line pattern is inside the end surface of the circuit board compared to the soldering of the pattern unrelated to the signal line. Therefore, when stress is applied in the direction of peeling off the flexible board 2 from the circuit board 1, stress is applied to the soldered portion of the pattern 40, which is unrelated to the signal line, and the signal line pattern 5
0 No stress is applied to the soldered part. In this way, stress is applied only to the soldered portions of the pattern 4 that are unrelated to the signal line, and stress is not applied to the soldered portions of the signal line pattern 60, so that the problem of pattern breakage does not occur. Further, the increase in cost due to providing a pattern unrelated to the signal line and soldering that pattern is small (and the large effect that pattern disconnection does not occur can be obtained).
