Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, in particular to a spraying device for an anti-oxidation layer of a ceramic substrate. Background Art

[0002] Ceramic substrate refers to a special process board in which copper foil is directly bonded to the surface (single or double sides) of alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate at high temperature. The ultra-thin composite substrate has excellent electrical insulation performance, high thermal conductivity, excellent soft solderability and high adhesion strength, and can be etched with various patterns like PCB boards, and has a large current carrying capacity. Therefore, ceramic substrates have become the basic materials for high-power power electronic circuit structure technology and interconnection technology.

[0003] In order to improve the spraying effect, the current traditional ceramic substrate anti-oxidation layer spraying device will stir the spraying material evenly to avoid the situation where the spraying material is precipitated and causes poor spraying. However, its stirring mechanism is generally relatively simple, which easily causes a retention layer of the spraying material during the stirring process, which will still affect the effect of some spraying. For this reason, we propose a ceramic substrate anti-oxidation layer spraying device to solve the above-mentioned problems. Utility Model Content

At the same time, two symmetrical air blowing mechanisms are distributed before and after the spraying of the ceramic substrate. The air blowing mechanism located before the spraying of the ceramic substrate can clean the dust on the ceramic substrate, thereby improving the spraying effect of the device. The air blowing mechanism located after the spraying plays a role in improving the drying efficiency of the paint, avoiding damage to the undried coating during the subsequent transfer of the ceramic substrate, thereby improving the success rate of the final processing.
