NOVELTY - The utility model claims a temperature difference control uniform glue developing heating unit, comprising a soaking plate body; the soaking plate body is divided into a tray upper surface plate, a graphene uniform temperature layer, an insulating heat conducting clapboard, an interlayer heating circuit and a bottom insulating pressing plate; the upper surface plate of the tray, a graphene uniform temperature layer, an insulating heat conducting clapboard; the interlayer heating circuit and the bottom insulating pressing plate are orderly set from top to bottom; the surface of the upper surface plate of the tray is a wafer heating surface; the surface of the upper surface plate of the tray upper surface is fixed high precision a temperature sensor. The temperature difference controls the uniform glue developing and heating unit to obviously improve the uniform heating effect of the hot disc.
