Flexibility testing method for flexible panels

Abstract

The invention discloses a flexibility testing method for a flexible panel. The flexibility testing method comprises the following steps: producing a to-be-tested sample, namely cutting the flexible panel, and bonding the two opposite sides of the cut flexible panels, so as to obtain the to-be-tested sample; producing an auxiliary testing device, wherein the auxiliary testing device comprises a first auxiliary testing piece and a second auxiliary testing piece which are oppositely arranged, and a height-variable testing channel is formed between the first auxiliary testing piece and the second auxiliary testing piece and is used for accommodating the to-be-tested sample; assembling the auxiliary testing device with a universal material testing machine, namely mounting the center of the auxiliary testing device in a sensing region of a sensor of the universal material testing machine; and testing, namely pushing the to-be-tested sample into the sensing region along the testing channel, so as to test the flexibility of the flexible panel. According to the flexibility testing method for the flexible panel, the auxiliary testing piece and the universal material testing machine are combined for use by virtue of simple operation, so that the testing efficiency is greatly improved; meanwhile, the operation errors such as sample fixation are avoided, and acquired data are stable and accurate.

Description

technical field [0001] The invention relates to the field of softness testing, in particular to a softness testing method for flexible plates. Background technique [0002] With the continuous development of electronic products in the direction of multi-functionality, miniaturization, light weight, and high performance, the requirements for the installation of flexible printed circuit boards (FPC) or rigid-flexible printed circuit boards are increasing. The installation is developing in the direction of three-dimensional 360-degree or even rotating installation. [0003] The key to three-dimensional 360-degree installation of FPC or rigid-flexible printed circuit boards is to ensure the softness of flexible sheets such as FPC, rigid-flexible printed circuit boards, or the substrates of the two, and most of the existing methods for testing the softness of flexible sheets It is only based on the touch, and only a small part is characterized by the resilience index. The specif...

Problems solved by technology

[0004] This method has the following disadvantages: ①It is necessary to fix the flexible plate to be tested on the fixture, which is complicated to operate and low in test efficiency; ②Fixed with screws, it is easy to install the flexible plate to be tested crookedly, the operation error is large, and the accuracy cannot be guaranteed; ③Resilience It is difficult to connect the test device with the material universal testing machine; ④ It is impossible to obtain the accurate correspondence between the softness and bending resistance of the flexible sheet, and cannot provide strong data support for the customer's three-dimensional 360-degree installation
