Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of substrate production and detection, in particular to an impedance detection device. Background Art
[0002] With the continuous development of display technologies, including flexible displays, display technologies have received increasing attention, providing people with richer interactive experiences. However, since the substrates of flexible displays are generally made of PI materials or PET (polyethylene terephthalate) materials, when bonding the substrate to the FPC and thermally pressing the COF to the FPC, compared with glass substrates, this material has poor stability, a larger coefficient of expansion, and is more likely to have a large amount of deformation.
[0003] Therefore, during the bonding process, the alignment difficulty increases, resulting in deformation of the gold fingers under pressure and misalignment of the bonding, reducing the effective bonding area of the gold finger lines. This further causes short circuits or open circuits in the bonding area, and there may also be a risk of excessive misalignment of the gold fingers in the bonding area between the FPC circuit board and the substrate or the COF, greatly reducing the stability of its electrical performance and ultimately resulting in a very low yield of the final product.
[0004] Therefore, to avoid the above situations, after bonding, the misalignment detection of the COF and FPC bonding and the impedance detection of the substrate and FPC will be performed simultaneously to determine the conductivity status. In the prior art, the detection equipment generally only has an impedance detection function, is not compatible with misalignment detection, and has low detection efficiency, affecting the detection accuracy and production efficiency.
