Description

FPC test equipment convenient to FPC board takes out

Technical Field

The invention relates to the technical field of FPC (flexible printed circuit) testing, in particular to FPC testing equipment convenient for taking out an FPC board.

Background

Flexible Printed Circuit, called FPC for short, also called Flexible Printed Circuit board, Flexible board, is a Printed Circuit board made of polyimide or polyester film as a base material, which has high reliability and excellent flexibility. The flexible printed circuit board can provide excellent electrical performance, can meet the design requirements of smaller and higher-density installation, is also beneficial to reducing assembly processes and enhancing reliability, can be freely bent, wound and folded, can be randomly arranged according to the space layout requirement, and can be freely moved and stretched in a three-dimensional space, so that the integration of component assembly and wire connection is achieved, and the flexible printed circuit board is widely applied to electronic products such as mobile phones, notebook computers, PDAs, digital cameras, LCMs and the like by the characteristics of high wiring density, light weight, thin thickness and the like.

In order to ensure that the quality of an electronic product using the FPC has absolute guarantee, the FPC is required to be subjected to performance test after the FPC is produced, the existing FPC testing equipment tests the FPC through a testing jig, a probe is arranged on a lower jig, the FPC is placed on the lower jig and is positioned through a pin during testing, the upper jig is made to descend to the position where the FPC needs to be tested, whether the testing is conducted or not is further tested, the testing result is displayed on a display screen, and a worker marks the FPC with poor testing result and selects the FPC.

However, in the prior art, the identification of the defective product is a manual identification, and since no label corresponding to the position displayed on the display screen is arranged on the FPC board, a certain response time is required when a worker searches for the corresponding position of the defective product, and then the worker manually holds the pen to fork the defective product at the corresponding position, so that the working efficiency of forking is low, the missing and the mistake are easy to occur, the test result of the product is influenced, and the defective product is leaked;

when the existing FPC testing equipment needs to test a large-size whole FPC board, the lower jig cannot support the whole FPC board due to the fact that the FPC material is soft, only a middle part of the FPC board can be tiled and droop around, the middle part of the FPC board can bulge upwards, a positioning hole in the FPC board is separated from a pin on the lower jig, and therefore the FPC board cannot be stably placed at a fixed position corresponding to a probe, and conduction testing effects are extremely influenced;

after the test is accomplished, the staff need lift a section distance with the FPC board, makes the locating hole on the FPC board break away from the pin on the tool down, just can take off the FPC board from the tool down, and the operation is inconvenient, and the staff pulls out FPC easily when the locating hole has not broken away from the pin completely yet, causes the damage to FPC.
