Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of MiP product production, in particular to a fixture for cutting glass-based MiP products. Background Art
[0002] MiP (micro in package) products are a new type of application of Micro LED display products. Specifically, a group of micro LED RGB chips are encapsulated into a relatively independent unit, and then the unit is transferred to a display control module to form a high-definition display product with a micron-level dot pitch. Specifically, several groups of Micro LED RGB chips are welded to a substrate with corresponding pads through mass transfer and welding technologies, and then the substrate is encapsulated. After the encapsulation is completed, the whole board is cut into independent units with a group of RGB chips as one lamp bead. The substrates used are generally BT substrates or glass substrates. Since the manufacturing precision of glass substrates is much better than that of BT boards, glass substrates have technical advantages when making products with relatively smaller pitch due to their higher precision requirements.
[0003] The existing cutting method is to paste the substrate encapsulated with Micro LED chips on a high-temperature tape. The glue used for the high-temperature tape is usually UV-reducing glue; then it is pasted on another layer of blue film, and the blue film is pasted on a circular enamel plate. The enamel plate is placed on the vacuum platform of the cutting machine and sucked tightly. It is cut by programming. The cutting depth is just enough to cut through the substrate to make it an independent unit. The cut glass-based material to be cut and the attached tape are taken down together. The specific operation is to irradiate it with UV light to reduce the viscosity and then peel off the glass-based material to be cut. However, the cut glass-based material to be cut is closely pasted on the tape one by one. During the peeling process, the glass-based part of the glass-based material to be cut will be broken or cracked due to external force, affecting the product yield and even the product quality.
