Abstract

The invention discloses a continuous vacuum welding furnace which comprises a working chamber, a feed inlet and a discharge outlet. Four vacuum cavity components are sequentially arranged inside the working chamber side by side and are respectively provided with independent temperature regulation and control systems, transmission systems, measurement systems and regulation and control systems; and a preheating area, a welding area, a precooling area and a cooling area which are four independent systems are formed inside the vacuum welding furnace, so that different processing procedures including a preheating stage, a heating stage, a precooling stage and a cooling stage can be respectively carried out. The invention further discloses an application method for the vacuum welding furnace. The continuous vacuum welding furnace and the application method have the advantages that the heating procedure and the cooling procedure can be carried out without interfering with each other under a vacuum or protective atmosphere condition, repeated temperature rise and temperature drop are omitted, accordingly, the welding time and power consumption can be saved, and the work efficiency and the welding quality can be improved.

Description

technical field [0001] The invention relates to a welding device and a welding method thereof, in particular to a continuous vacuum welding furnace and a welding method thereof. Background technique [0002] As electronic component packages shrink in size and power levels increase, the need for void-free soldering arises. Since welding in a low-oxygen or oxygen-free environment can reduce the generation of voids in the welding process and improve the quality of welding, people have always hoped that the welding process can be carried out in a low-oxygen or oxygen-free environment. However, most of the current welding furnaces are welded in the atmospheric environment, the generation of voids cannot be controlled, and the quality of welding is not high. [0003] In addition, for the vacuum welding furnace in the prior art, the whole process of welding is generally realized in one cavity space. Each soldering job needs to be heated from room temperature to soldering temperat...
