Double-sided etching device and etching process for metal radiating fin

Abstract

The invention relates to the technical field of etching, in particular to a double-sided etching device for a metal cooling fin and an etching process applied to the double-sided etching device. The turnover mechanism comprises a machine body, a first clamping mechanism, a first turnover mechanism, a second clamping mechanism and a second turnover mechanism, the first clamping mechanism, the first turnover mechanism, the second clamping mechanism and the second turnover mechanism are arranged on the machine body, the first clamping mechanism and the second clamping mechanism are used for clamping the two sides of the metal cooling fin correspondingly, and the first turnover mechanism is used for driving the first clamping mechanism to turn over; the second turnover mechanism is used for driving the second clamping mechanism to turn over. The first clamping mechanism and the second clamping mechanism are used for clamping the two ends of the metal cooling fin correspondingly, after one face of the metal cooling fin is etched, the first overturning mechanism and the second overturning mechanism are used for driving the first clamping mechanism and the second clamping mechanism to overturn at the same time correspondingly, and then the metal cooling fin can be overturned; therefore, the other side of the metal radiating fin is etched.

Description

technical field [0001] The invention relates to the technical field of etching, in particular to a double-sided etching device and an etching process for a metal heat sink. Background technique [0002] Metal heat sinks are widely used in high power density and integrated electronic devices to reduce the heat accumulation of heating components and prolong the working life of the devices. At present, the metal heat sink can be used as the shell of the phase change heat transfer device, and the high-wetting performance liquid absorbing core is encapsulated inside. After sealing and vacuuming the working medium, it becomes an efficient phase change heat transfer device with good thermal conductivity. The metal heat sink can also be used as a common heat sink, and microarray columns are etched on the upper and lower surfaces of the metal heat sink to increase the specific surface area of ​​the metal heat sink, thereby improving the heat dissipation efficiency of the metal heat s...
