Gas heater for chip drying

Abstract

The invention discloses a gas heater for chip drying. The gas heater for chip drying comprises a shell, a heating assembly and a gas flow channel assembly, wherein the shell is provided with a quartzglass tube, a quartz upper cover plate and a quartz bottom plate, the quartz upper cover plate and the quartz bottom plate are correspondingly connected to two axial end openings of the quartz glass tube in a sealing mode, and the quartz glass tube, the quartz upper cover plate and the quartz bottom plate are also enclosed together to form an accommodating cavity; the heating assembly is providedwith a carbon fiber heater built in the accommodating cavity and two wires correspondingly and electrically connected with the carbon fiber heater; the gas flow channel assembly is provided with a quartz gas tube and two gas connecting openings mounted in the outer wall of the quartz glass tube; the quartz gas tube is built in the accommodating cavity and also sleeves the carbon fiber heater, thequartz gas tube communicates with the accommodating cavity through a gas inlet of the quartz gas tube, one gas connecting opening communicates with the accommodating cavity, and the other gas connecting opening communicates with a gas outlet of the quartz gas tube. When a chip is dried by the gas heater, the situation that the chip is polluted is avoided, and thus the quality of the chip is ensured.

Description

technical field [0001] The invention relates to the technical field of chip processing, and specifically provides a gas heater for chip drying. Background technique [0002] At present, in the chip production industry, there are mainly two commonly used chip drying methods: ① Use high-speed centrifugation to dry the chip. ②Using the gas heating method to dry the chip, the specific drying method is: use the heat generated by the nickel-chromium heating wire to heat the gas and blow out the high-temperature gas, and the high-temperature gas will dry the chip. [0003] However, with the development of the chip industry, the diameter of the chip is getting bigger and bigger, and the thickness is getting thinner and thinner. The traditional drying method will cause damage to the chip. Although the high-temperature gas drying method can avoid the problem of chip damage, since the nickel-chromium heating wire is processed with metal, it will precipitate metal ions, thereby contami...

Problems solved by technology

The traditional drying method will cause damage to the chip. Although the high-temperature gas drying method can avoid the problem of chip damage, because the nickel-chromium heating wire is processed with metal, it will precipitate metal ions, thereby contaminating the chip.
