Description

Technical Field

[0001] The utility model relates to the field of flexible circuit boards, and more specifically, to a high-flat pad tensile-resistant LED flexible continuous long board. Background Art

[0002] Flexible circuit boards are relatively soft. To ensure the flatness of the device pads before welding, high-precision devices need to be reinforced on the back. The general solution is to stick a layer of metal steel sheet or PI, FR4, and other reinforcing materials on the back of the pads. The thickness is generally 0.05-0.3mm to achieve the flatness of the pads.

[0003] If metal steel sheets or PI, FR4 and other reinforcement materials are used, they must be bonded together with thermosetting adhesive, which not only increases the cost, but also the adhesive is prone to failure, resulting in reinforcement peeling. The production and processing efficiency is also relatively low. The reinforcement is generally smaller than the product, has a specific area, and has certain precision requirements, so it can only be processed by equipment, and a large amount of equipment investment is required, which adds burden to the enterprise;

[0004] Traditional processes can only produce sheet materials. After pasting and reinforcement, they are handed over to customers to paste components and lamp beads, and then the customers connect them into 5-100 meters of finished products. When the sheet materials are connected to the board, the user will be unable to withstand bending during the installation process, and there is a risk of broken boards;

[0005] Therefore, in order to solve the above problems, a LED flexible continuous long board with high flat pad tensile strength is proposed. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a flexible continuous long LED board with high flat pad tensile strength to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-flat pad tensile resistance LED flexible continuous long board, including a flexible circuit board, characterized in that the interior of the flexible circuit board is composed of a top white film, a top copper foil, a PI layer, a bottom copper foil and a bottom white film, wherein the thickness of the PI layer is higher than that of the other layers, and a plurality of groups of pin holes are provided on the surface of the flexible circuit board, LED lamp beads and components can be arranged at the top of the pin holes, and the flexible circuit board can be processed 500 meters at a time.

[0008] Preferably, the flexible circuit board can be laid on the surface of the working platform, a card slot is provided on the top of the working platform, and a card block can be provided at the bottom of the flexible circuit board, and the card block is card-engaged with the card slot.

[0009] Technical effects and advantages of the utility model:

[0010] Compared with the prior art, the utility model combines the accuracy and flatness of the product pad, the thickness and performance of the reinforcement. The material of the flexible circuit board is composed of copper foil and PI layer. The utility model thickens the thickness of the PI layer, makes it reinforced, and integrates it with the copper foil material. There is no need to add reinforcement materials to strengthen it, which reduces the processing cost. At the same time, the production process of the utility model is continuous production, and long boards within 500 meters can be processed at a time. When the operator pastes components and LED lamp beads, the production can be automatically stopped, which improves the production efficiency. Moreover, because the 500-meter product is continuous and integrated, the tensile strength is very strong, and there is no risk of the user breaking the board during installation.
