  First, the ceramic heating element features:
 
  High temperature ceramic heat for baking (MCH) is directly on AL2O3 alumina ceramic green printed resistor paste after, at a high temperature of about 1600 ℃ for baking, and then by a new generation of electrode leads after treatment, the production of low temperature heating element. is the second alloy heating wire, and a new generation after the PTC heating elements are widely used in daily life, industrial and agricultural technology, telecommunications, health care, environmental protection and many other fields and other low-temperature heating needs. In terms of household electric appliances: such as a small warm air from warming, hair dryer, dryer, heater, air phones, dryers, electric plywood, electric irons, electric irons, straight hair, curly perm, electronic thermos in the electronics industry-specific terms such as small crystal devices thermostat;, cabinet, electric cooker, Commode ceramic heaters, water heaters, etc; in industries such as industrial drying technology equipment, electric bonding, a water heater, oil and acid-base liquid trough; in health care, such as infrared physiotherapy, intravenous fluid heater and so on.
 
  Second, the background information:
 
  With the advent of the era of integration of various electronic devices, electronic machine for circuit miniaturization, high density, versatility, reliability, speed and power of a higher demand because co-fired ceramic substrate able to meet many of the requirements for electronic machine circuit, so in recent years has been widely used. Co-fired ceramic substrate can be divided into high-temperature co-fired ceramic (HTCC) substrate and a low temperature co-fired ceramic (LTCC) substrate two kinds. High-temperature co-fired ceramic LTCC compared with high mechanical strength, high wiring density, chemical stability, high thermal coefficient and low cost materials, higher thermal stability requirements, require less volatile gas temperature, require higher heat sealing and packaging areas, has been more widely used. HTCC ceramic heat primarily to replace now the most widely used alloy wire heating element and the PTC heating element and its components. The existence of high-temperature alloy wire heating element is easily oxidized, short life, there is fire safe, low thermal efficiency, uneven heating and other shortcomings; PTC heating element and the heating temperature is generally only about 200 ℃, the heating temperature is higher than 120 ℃ of the commonly used four lead oxide, which are due to the large genus of leaded products being eliminated.
