Assembly process for IGBT (insulated gate bipolar transistor)

Abstract

The invention discloses an assembly process for an IGBT (insulated gate bipolar transistor). During the assembly process, a plurality of working position points are set, a working position device region is arranged in each corresponding working position point, and several inspectors are assigned. The assembly process for the IGBT comprises the following steps of: (1) setting a working position 1 where insulating silicone grease is coated; (2) setting a working position 2 where the IGBT and a radiator are pre-fastened; (3) setting a working position 3 where the radiator is fastened; (4) setting a working position 4 where heating resistors are assembled in the preset positions; (5) setting a working position 5 where a driving circuit board is fixed; (6) setting a working position 6 where the modular internal wiring of the component formed in the step (5) is completed; and after the above steps are completed in order, delivering the semi-finished products to a storage region. The process improves quality control and increases work efficiency.

Description

technical field [0001] The invention relates to the field of processing high-precision devices such as electronic components, in particular to an IGBT assembly process flow. Background technique [0002] At present, the production method of high-precision devices such as IGBT is to use one person to operate multiple tasks, which is likely to cause irregular assembly actions, and the assembled products cannot reach the professional level, which affects product quality. There is no professional working platform for the existing operations. Due to the radiator and IGBT has very strict requirements on surface flatness, so if there is no professional working platform, the surface of components will be damaged, resulting in the performance of components being affected, and the existing working method does not have proper protection in transportation Measures, such as the weight of the radiator is still quite large, but there is no suitable means of transportation, the workers carr...

[0002] At present, the production method of high-precision devices such as IGBT is to use one person to operate multiple tasks, which is likely to cause irregular assembly actions, and the assembled products cannot reach the professional level, which affects product quality. There is no professional working platform for the existing operations. Due to the radiator and IGBT has very strict requirements on surface flatness, so if there is no professional working platform, the surface of components will be damaged, resulting in the performance of components being affected, and the existing working method does not have proper protection in transportation Measures, such as the weight of the radiator is still quite large, but there is no suitable means of transportation, the workers carry the radiator or IGBT with bare hands, once an accident occurs, the components will be damaged, and the cost of the IGBT is very high, once it is damaged, it cannot be used , will cause considerable economic loss
