**Raw Material Mixing** General-purpose ceramic products create a liquid slurry through a crushing and mixing process of the obtained raw materials. For custom products, we produce the desired slurry according to the specified formulation (recipe). **Green Sheet Coating** The slurry created in the mixing process is thinly coated onto PET film using a coating machine. After that, a sheet-like "green sheet" is created by pre-drying it with warm air.

【Green Sheet Coating】 A slurry produced through the mixing process is thinly coated onto PET film using a coating machine. After that, a sheet-like "green sheet" is created by pre-drying it with warm air. 【Mold Press Processing】 The green sheet is precisely punched into the required size using a mold.
-
【Mold Press Processing】 The green sheet is punched out to the required size using a precision mold. 【Continuous Firing Process】 The green sheets, which have been separated through mold press processing, are fired in a continuous firing furnace to become ceramic substrates. The green sheets contain organic materials such as binders, but these organic materials are removed during the debinding process prior to the final firing.
-
【Circuit Printing Process】 The printed material is patterned onto the completed ceramic substrate using the screen printing method. The printing material is not limited to electrode paste for circuit wiring; multilayer printing combined with insulating layers is also possible.
