Ceramic substrate casting production line is not a common term or process flow. Ceramic substrates typically refer to ceramic basic materials used in the fields of electronics, optoelectronics, and semiconductors, used in the manufacturing of circuits, sensors, and other electronic components.
The manufacturing of ceramic substrates typically involves the following process steps:
Raw material preparation: Select suitable ceramic materials, such as alumina (Al2O3), silicon nitride (Si3N4), or zirconia (ZrO2). The raw materials need to be screened, mixed, and ground to obtain a uniform ceramic paste.
Casting: Pour the porcelain slurry into the feeding groove of the casting machine, and evenly cast the porcelain slurry onto the casting strip through the roller or scraper of the casting machine. Tape casting is usually made of heat-resistant metal materials, such as molybdenum (Mo) or tungsten (W).
Forming: Use a mold or roller to shape the ceramic slurry on the tape, forming the required shape and size of the ceramic substrate.
Drying: Properly dry the formed ceramic substrate to remove moisture.
Sintering: Place the dried ceramic substrate into a high-temperature kiln for sintering to achieve the required mechanical properties and chemical stability. The sintering temperature and time are controlled according to the characteristics and requirements of the ceramic material.
Post processing: Process, trim, and polish the sintered ceramic substrate to obtain the final product.
The production process and technical advantages of ceramic substrates are similar to those of general ceramic products. Ceramic substrates have excellent insulation performance, high-temperature resistance, and chemical stability, making them suitable for fields such as high-frequency electronic devices, sensors, and microelectronics technology.
However, there are also some process difficulties in the manufacturing of ceramic substrates, such as controlling the uniformity of the ceramic slurry, controlling the temperature and thickness during the casting process, and addressing shrinkage and deformation during the sintering process. These difficulties need to be solved through precise process parameter control and optimization to obtain high-quality ceramic substrates.
