Embodiment 1
[0030] figure 1 It is a structural schematic diagram of the ceramic heater supporting base in Example 1 of the present invention.
[0031] Such as figure 1 As shown, this embodiment provides a ceramic heater support base, the surface of the ceramic heater support base is formed with a first region 1 and a second region 2; the roughness of the first region 1 is greater than that of the second region 2 . A conductive material layer is disposed on the first region 1 .
[0032] The roughness of the first region 1 is large, and the conductive material layer deposited on the first region 1 is not easy to fall off, and the roughness of the second region 2 is small, and the conductive material layer deposited on the second region 2 is easy to fall off. In this embodiment, the fine control of the surface roughness of the first area 1 and the second area 2 of the ceramic heater support base is carried out. After the conductive material layer is deposited on the surface of the ceramic ...
Embodiment 2
[0044] figure 2 It is a structural schematic diagram of the ceramic heater of Example 2 of the present invention.
[0045] Such as figure 2 As shown, the ceramic heater of this embodiment includes the ceramic heater supporting base of Embodiment 1, and further includes a conductive material layer and an insulating layer arranged in sequence; the conductive material layer covers the first region 1 .
[0046] With the insulating layer protection resistor, it can be used stably even in a high-temperature heating process near 1500°C, and even in a heating process that rapidly raises and lowers the temperature at a rate of 100°C / min or more.
[0047] Wherein, the first area 1 protrudes from the second area 2 .
[0048] Specifically, the conductive material layer is made of pyrolytic graphite. The thickness of the conductive material layer is preferably 10-300 μm, more preferably 30-150 μm. When energized, the conductive material layer generates heat to heat the object to be hea...
Embodiment 3
[0051] image 3 It is a structural schematic diagram of the ceramic heater of Example 3 of the present invention.
[0052] Such as image 3 As shown, the difference between the ceramic heater of this embodiment and Embodiment 2 is that the second region 2 of this embodiment protrudes from the first region 1 .
[0053] The present invention aims to protect a ceramic heater support base and a ceramic heater, by finely controlling the surface roughness of the first area and the second area of the ceramic heater support base, when a conductive material layer is deposited on the ceramic heater support After being on the surface of the substrate, the conductive material on the conductive area is closely attached to the first area, and the conductive material on the insulating area can fall off naturally or be removed by a simple tool such as a knife. The operation is simple, the pattern is beautiful, and the edge of the conductive material layer Neat, without layers, so that the...
