Typical microwave assemblies include tens or even hundreds of chips, wherein expensive and complex-function chips, such as modulator chips, sensor chips, etc., are packaged in a gel box, so as to prevent the chips from being damaged due to collision, affecting the performance of the chips, and even causing scrap. The gel box has certain viscosity, and the chip in the gel box cannot be directly picked up by the manual dispensing chip mounter, so that the chip in the gel box is clamped into the carrying box by using tweezers before manual mounting, and then mounting is carried out, so that damage such as chip edge breakage and the like is easily caused in the chip clamping process, and particularly, the edge breakage is easily caused on thin and fragile chips such as gallium arsenide and the like, and the production cost is increased.
Therefore, chinese patent publication No. CN111132539A discloses a tool and a method for nondestructively mounting a chip in a gel box by using a manual dispensing chip mounter, the tool includes an objective table, a vacuum adsorption table located at one corner of the objective table, and a support table located at the bottom surface of the objective table, wherein the vacuum adsorption table has a threaded through pipe penetrating through the objective table and extending to the back surface of the objective table, and the vacuum adsorption table is used for adsorbing the gel box. The gel box is fixed through the vacuum adsorption platform, the gel layer is arranged on the objective table to fix a product to be pasted, then a chip in the gel box is picked up by using a manual dispensing chip mounter, and the chip is pasted on the product to be pasted.
However, since the ring groove on the vacuum adsorption platform is not communicated with the central through hole, only the central through hole really plays a role when the gel box is adsorbed, the adsorption force on the gel box is small, and the gel box is not effectively fixed and is easy to displace; in addition, the object stage is provided with a gel layer, and dust is easily adsorbed on the gel layer, which is not beneficial to keeping the surface of the object stage clean.
