Embodiment Construction

[0015] Below in conjunction with the accompanying drawings and examples, the specific implementation of the present invention will be further described in detail, the following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0016] A multi-channel FPC test device of the present invention includes a Sensor test device, a three-in-one IMU_FPC test device, a Light&Proximity_FPC test device and a MICFPC test device, and the Sensor test device is used to expand three or more test interfaces to achieve high efficiency The three-in-one IMU_FPC test device checks whether the FPC is installed properly through initialization. The Light&Proximity_FPC test device automatically detects whether the FPC is a good product. The MICFPC test device tests the FPC through the MIC drive circuit and the indicator circuit. It supports multiple It can detect various FPCs with different functions, and the detection of different styles of FPCs...

Abstract

The invention relates to the technical field of multi-path FPC testing devices, in particular to a multi-path FPC testing device which is easy to operate, accurate and clear in testing result and capable of rapidly and accurately judging defective product problem points. Not only can multi-channel FPCs of the same style be tested at the same time, but also multi-channel detection of FPCs with different functions can be supported at the same time. And the detection of different styles of FPCs is mutually independent, so that the detection personnel can conveniently and quickly detect whether the produced FPCs are good products or not only by performing different test operations on the different FPCs, and the problem points of defective products can also be quickly and accurately positioned.

Description

technical field [0001] The invention relates to the technical field of a multi-channel FPC testing device, in particular to a hardware circuit design for basic function inspection and defective point judgment of FPCs containing functional modules such as Sensor and MIC. Background technique [0002] With the development of electronic equipment, the functions of products are becoming more and more complex, but the structural space of products is getting smaller and smaller, and the layout area of ​​motherboards is also getting smaller and smaller. Moreover, many devices, such as IMU, Light Sensor, Proximity Sensor, MIC and other devices have special requirements on the placement, direction and EMI performance of components, so the demand for various FPC boards is constantly increasing. However, due to the miniaturization of component packages, the process requirements for FPC production equipment are also getting higher and higher. How to efficiently mass produce is a proble...
