Problems solved by technology

But when the gold finger 14 grayscale variation on the substrate 12 is large (such as Figure 1A and Figure 1B circled place), the grayscale sampled when the device detects the conductive film layer 16 will be different from the image sampling grayscale value set in the device
Therefore, the conductive film layer 16 is attached normally, but the equipment gives an alarm of poor attachment;

Embodiment Construction

[0027] see Figure 2A , Figure 2B and Figure 2C , is a flow chart of a preferred embodiment of the present invention and a side view and a top view of attaching a conductive film to a substrate. As shown in the figure, according to the detection method for attaching a conductive film of the present invention, a substrate 22 is first provided (step S1), a gold finger 24 is arranged above the substrate 22, and a conductive film layer 26 is arranged on the gold finger 24; after that, Use a light source 27 to illuminate the side of the substrate 22 (step S2); then, use an image sensor 28 to receive the reflected light of the conductive film layer 26 to generate a grayscale image (step S3); then, use a software to calculate the grayscale image to obtain a thickness (step S4). Finally, determine the size of the thickness to determine whether the conductive thin film layer 26 is wrongly attached (step S5). When the thickness is less than the first threshold value, that is, the ...

Abstract

The invention supplies a measure method of attach conductive film, the method includes: supplying one plaque, upper the plaque there is a gold finger with a conductive film layer; using a light sourceexposure the side face; using a image sensor receive the reflected light of conductive film layer and produce a gray level image; using a software compete the gray level image to find the thickness orlength; and judging the size of thickness or length, judge the conductive film layer error while the thickness less then the first threshold number or the length less then the second threshold number . More accurate detection of conductive film layer attaches errors in order to reduce error detection in the case.

Description

technical field [0001] The invention relates to a detection method, in particular to a detection method for attaching a conductive film. Background technique [0002] Anisotropic Conductive Film (ACF) is a film containing metal particles in a thermosetting or thermoplastic resin adhesive. Its main function is only to provide electrical conduction in the vertical direction of the two bonding objects, and in the horizontal direction. It has the effect of insulation, and has the characteristics of bonding and conduction. It is a connection material with up and down conduction and left and right non-conduction. It can be used for high-density lead connection between display panels and circuit boards. At present, the circuit board of the display is mostly attached with an anisotropic conductive adhesive film. In the prior art, the anisotropic conductive adhesive film attachment detection method is that the equipment personnel use a photo-charge coupled device (CCD) sensor to dir...
