Problems solved by technology

[0003] The purpose of the present invention is to provide a vacuum heating table, which has the advantages of creating a vacuum environment during heating, thereby reducing heat loss and increasing heating efficiency, and solves the problem that the current heating table cannot create a vacuum environment when heating workpieces. As a result, there are more heat losses during heating, wasting energy, and the heating efficiency is low, and the heating takes a long time.

Abstract

The invention discloses a vacuum heating bench. The bench comprises a shell, a cover plate, a touch screen and a heating plate. A cushion block is fixed to a surface of a bottom end of the shell. A touch screen is embedded in the surface of one side of the shell. An indicating lamp and a knob switch are embedded in one side, located on the touch screen, of the surface of the shell. A fan is fixedto a side end surface of one side of the shell. A heating plate is embedded in the surface of a top of the shell. A rubber pad is attached to an outer side of the heating plate. A first side plate anda second side plate are welded to positions, located on one side of the heating plate, of an upper surface of the shell. The cover plate is rotatably installed above the shell through the first sideplate and the second side plate, a clamping groove is arranged in the surface of the bottom end of the cover plate, and the size of the clamping groove is matched with the size of the rubber pad. Thebench has an advantage that a vacuum environment can be created during heating so that heat losses are reduced, and heating efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of heating tables, in particular to a vacuum heating table. Background technique [0002] Microwave hybrid integrated circuits are developing towards high performance, high reliability, miniaturization, high uniformity and low cost, and put forward high requirements for chip welding technology. When interconnecting chips, components, etc. with carriers (such as substrates, shells, etc.), the main implementation methods are conductive adhesive bonding and eutectic welding. For high-end microwave frequencies or high microwave power, eutectic welding has the advantages of small resistivity, small thermal conductivity, small thermal resistance, low microwave loss, and high reliability. It is impossible to create a vacuum environment during heating, resulting in a large heat loss during heating, wasting energy, and the heating efficiency is low, and the heating takes a long time.
