Rigid-flex board and mobile terminal

Abstract

The invention relates to a rigid-flex board and a mobile terminal. The rigid-flex board comprises a flexible substrate layer and a copper foil layer, wherein the copper foil layer is laminated on the flexible substrate layer and is provided with a test point and a via hole, the via hole is arranged on one side of the test point and is separated from the test point, the rigid-flex board also comprises a connection wire, and the two ends of the connection wire are separately connected with the test point and the via hole. In the rigid-flex board and the mobile terminal, the via hole and the test point are arranged at intervals and are connected by the connection wire, thus, signal connection between the test point and the via hole is achieved. When a test device is used for testing, the situation that the via hole is penetrated by a top needle of the test device to cause disconnection between the via hole and the connection wire can be prevented due to no via hole formed in the test point, and the normal running of test is ensured; and moreover, the via hole is not formed in the test point, the situation that the top needle of the test device is sunken into the via hole to cause that the test cannot be completed can be prevented, and the normal running of the test is further ensured.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a rigid-flex board and a mobile terminal. Background technique [0002] Rigid-flex boards are more and more widely used because they have the properties of both soft boards and rigid boards. Therefore, it is an essential process to detect the functional circuits on the rigid-flex board after it is produced. At present, when performing functional tests on rigid-flex boards, test production fixtures are usually used for testing. The test production jig is usually equipped with a thimble, which is used to push against the pad of the test point, and then the other end of the thimble is connected to the test equipment to check the working condition of the functional circuit on the soft-hard combination board. [0003] However, using the above method, since the thimble is a thing with a sharp point, when testing, the center of the test point is provided with a via hole; The t...

Problems solved by technology

[0003] However, using the above method, since the thimble is a thing with a sharp point, when testing, the center of the test point is provided with a via hole; The top penetration breaks the connection between the wiring in the via hole and the via hole, resulting in an open circuit on the circuit on the flexible and rigid board, and the test cannot be completed

In addition, since a via hole is opened at the center of the test point, the thimble is easily trapped in the via hole during the test, resulting in poor contact, and the accuracy of the test cannot be guaranteed.
