Flexible circuit board touch screen substrate testing device

Abstract

The invention relates to the technical field of circuit board testing, in particular to a flexible circuit board touch screen substrate testing device. The device comprises an operation table, and a fixing structure is arranged on the top side of the operation table; a reset structure is connected between the fixing structure and the operation table; an observation structure is arranged on the inner side of the operation table; an amplification structure is mounted on the top side of the operation table; and a contact structure is mounted on one side of the operation table. A flat cable is pressed and flattened on the table top through the fixing structure, so that testing personnel can conveniently conduct testing. The pressed and fixed state of the flat cable can be kept through the reset structure, and meanwhile, an anti-skid pressing wheel can be rapidly lifted up to take out the flat cable. The bottom side of the to-be-tested flat cable is observed in real time through the observation structure, and a tester can conveniently obtain more comprehensive circuit information. The surface of the flat cable with fine and dense circuit distribution is observed through the amplification structure, and a specific point at one end of the flat cable is continuously connected through the contact structure, so that the test work is further facilitated.

Description

technical field [0001] The invention relates to the technical field of circuit board testing, in particular to a flexible circuit board touch screen substrate testing device. Background technique [0002] A flexible circuit board, also known as a "soft board", is a printed circuit made of a flexible insulating substrate. Flexible circuits provide excellent electrical performance to meet the design needs of smaller and higher density installations, and also help reduce assembly steps and enhance reliability. Flexible circuit boards are the only solution to meet the miniaturization and mobility requirements of electronic products. It can be bent, wound, and folded freely, and can withstand millions of times of dynamic bending without damaging the wires. It can be arbitrarily arranged according to the spatial layout requirements, and can be moved and stretched arbitrarily in three-dimensional space, so as to achieve the integration of component assembly and wire connection.

[0003] However, because most of the cables used in the touch screen are long strips, and there are usually a large number of circuits printed on it, it is inconvenient for testers to observe during the test. At the same time, due to the softness of the flexible circuit board, the circuit board will Flattening is usually required during the process, which further increases the difficulty of detection
