Background technique

At present, with the development of electronic technology, the space of electronic components is getting smaller and smaller, and the connection density of electronic components is getting larger and larger, which makes it difficult for heat to dissipate, resulting in more and more heat accumulation in electronic products. In order to solve the heat dissipation problem of electronic products, it is often necessary to paste graphite composite films with high heat dissipation properties on the covers of electronic components that generate large amounts of heat. In the existing technology, the product is manually clamped and fixed on a special jig, and then a graphite composite film with high heat dissipation is attached, and the bottom film is peeled off. The existing fixture only positions the product and does not position and clamp the product and the composite film together, resulting in large errors and low precision in product film application, which directly affects the qualification rate of product production. Therefore, it is necessary to design a high-precision laminating jig with positioning guide.
