Problems solved by technology

[0003] The MCH co-fired ceramic heating substrate and its preparation method are electric heating elements independently developed by the inventor. Because there is no temperature adjustment control device, the phenomenon of burning out components or auxiliary devices often occurs due to excessive temperature in production and application, and the product performance is extremely high. unstable

Embodiment 1

[0020] Such as figure 1 , 2 , 3, the constant temperature fired ceramic heating substrate and the preparation method thereof according to the present invention are characterized in that: the constant temperature co-fired ceramic heating substrate comprises two or three laminated ceramic substrates 5, 6 or 7, 5, 6. The ceramic substrates 7, 5, and 6 are carriers, and the laminated layer is packaged with a resistance heating circuit board 2 printed with resistance paste;

[0021] The laminated layer of the ceramic heating substrates 5 and 7 is packaged with a constant temperature resistance plate 3 printed with a constant temperature resistance paste; the two ends of the resistance heating circuit board 2 are respectively welded with silver and copper sheets 8, and the silver and copper sheets at one end are Metal leads 1 are directly brazed on 8; metal leads 4 are brazed on the silver copper sheet 8 at the other end, and constant temperature resistance plates 3 are connected b...

Embodiment 2

[0022] Embodiment two: if figure 1 , 4 , as shown, ( Figure 4 The ceramic substrate 5 is not shown in the figure), the ceramic substrate 5 or 6 is used as the carrier, and the resistance heating circuit board 2 and the constant temperature resistance board 3 are printed on one side of the carrier, and the two ends of the resistance heating circuit board 2 are respectively connected to the silver copper sheet 8 Among them, the silver-copper sheet 8 at one end is directly welded with a metal lead 1, and the metal lead 4 welded on the silver-copper sheet 8 at the other end is connected to the two ends of the constant temperature resistance plate 3, and the ceramic substrate 6 and the ceramic substrate 5 are stacked. Press-packed resistance heating wire version 2, constant temperature resistance version 3.

[0023] Of course, the above-mentioned embodiment is a preferred solution, if one end of the resistance heating circuit board 2 printed on the carrier is welded with silver ...

Abstract

The invention discloses a constant-temperature co-fired ceramic heating base plate and a preparation method thereof. The constant-temperature co-fired ceramic heating base plate comprises two or three layers of laminated ceramic base plates (5), (6) or (7), (5), (6); the ceramic base plates (7), (5), (6) are taken as carriers, a resistor heating circuit board (2) printed with resistor slurry is packaged in the laminated layers; a constant-temperature resistor board (3) printed with constant-temperature resistor slurry is packaged in the laminated layers of the ceramic heating base plates (5), (7); and sliver copper sheets (8) are welded on both ends of the resistor heating circuit board (2). The purpose of the invention is to provide the constant-temperature co-fired ceramic heating base plate with rapid warming, high thermal efficiency, energy saving, uniform heating, long service life and low power attenuation and the preparation method thereof. Particularly due to addition of a temperature control component and insulating layers, the ceramic heating base plate has the function of automatic control of heating temperature.

Description
