Definitions
- This invention concerns improvements relating to electric heating
- Ceramics material substrates are also known. Such thick film heating
- the low power density of the lower power track means that it cannot
- this object can be achieved by a
- thick film heating element having a multi-layered construction with different
- intermediate layer would only have to withstand 250N, perhaps with a high
- the intermediate insulating layer can be
- the reduced thickness of the intermediate layer will also be acceptance.
- the reduced thickness of the intermediate layer will also be acceptance.
- the various firing operations may be combined by firing multiple layers at
- the additional track(s) may include other features, such as an
- Patent Application No. for example, and tappings from either track
- underlying track could be made through holes in the intermediate insulating layer, and access to the tracks for bimetal or other sensors can also be similarly provided.
- Figures 1A to IE illustrate various steps in the manufacture of an exemplary thick film heating element embodying the present invention
- Figure 2 is a perspective cross-sectional view of a thick film heating
- Figure 1A illustrates the provision of a
- the dielectric layer 1 on one surface of a stainless steel substrate 2.
- material can for example consist of a glass, ceramics or glass ceramics
- Figure IB shows the provision of a main
- printing step employing electrically conductive ink followed by a firing step.
- Figure 1C illustrates the provision of an intermediate electrically
- second window opening 8 exposes a portion of the main heater track 3 for
- the terminal parts 5, 6, 14 and 15 are provided with low resistance silver
- the heating element tracks 3, 9 turn back upon themselves so as to avoid the
