低温焊;
Eutectic furnace is a special equipment based on the eutectic principle, packaging chip according to different eutectic technological requirements of welding alloy materials under a vacuum or inert gas protection environment.
共晶炉就是基于共晶原理开发的专用设备,在真空或惰性保护气体环境中按照不同焊接合金材料的共晶工艺要求,完成芯片的封装。
Application of eutectic point left movement theory in development of new type cast iron welding electrodes
共晶点左移理论在研制新型铸铁焊条时的应用
The low melting-point eutectic films crack under the welding tensile stress caused by thermal expansion and contraction of magnesium alloy. The formation mechanism of liquefied cracks is similar to crystallization cracks.
液化裂纹的产生机理与焊缝结晶裂纹相似,即同样是在低熔点的液态薄膜的形成和焊接拉应力作用下产生。
