Description
Technical field
The present invention relates to semiconductor device packaging technique field, particularly relate to a kind of instrument carrying out when installing for IGBT module top cover and assisting.
Background technology
Insulated gate bipolar transistor (InsulatedGateBipolarTransistor, in full it is called for short IGBT) there is altofrequency, high voltage, big electric current, the performance characteristics that especially easily turns on and off, it it is the most representational product of the Power Electronic Technique third time revolution generally acknowledged in the world, so far having evolved to for the 6th generation, commercialization had evolved to for the 5th generation.At present, IGBT is widely used in all trades and professions of national economy.
IGBT module is mainly used in major loop inverter and all inverter circuits of converter, namely in DC/AC conversion.The novel power transistor being representative with IGBT module now is high-frequency power electronic circuit and the core switching components and parts controlling system, now being widely used to the fields such as electric locomotive, high voltage power transmission and transforming, electric automobile, servo controller, UPS, Switching Power Supply, power of chopping, market prospect is very good.
The semicon industry of China is for encapsulation the growing up gradually of IGBT module, but for the encapsulation of high-power IGBT module, only minority enterprise in the field of business knows core technology.The top cover of IGBT module and shell are outermost protections, and the level of its installation directly decides the service life of module, and the encapsulation for IGBT module seems extremely important.
At present, top cover shell mounting technique semiconductor applications at home about high-power IGBT modules such as 6500V still belongs to the blank stage, even if there is this technology in the manufacturer that part has the ability to be packaged, but also all as the trade secret of this enterprise, without disclosed data that can be for reference.
During IGBT module encapsulation, owing to indivedual top covers are likely to producing or producing miniature deformation in transportation, cause top cover after mounting and between shell gap excessive, the problem that ultimately forms Lou glue.Owing in normally producing, top cover deformation quantity in a pre-installation is smaller, it is impossible to the naked eye directly find out, so whether the gap only just can found out after mounting between top cover and shell is beyond the scope designed.The excessive touchstone making IGBT module finally not reach this operation in gap after top cover solidification, it is difficult to carry out follow-up work.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of instrument carrying out when installing for IGBT module top cover and assisting, during in order to overcome IGBT module to encapsulate, top cover miniature deformation causes that top cover and housing slot are excessive causes leakage glue, it is impossible to the problem reaching touchstone.
For achieving the above object, the present invention provides following technical scheme:
The auxiliary installation tool for head cover of IGBT module of the present invention, including base plate, vertically it is located at two groups of columns on described base plate and is respectively arranged on the first crossbeam on described column and second cross beam, described two groups of columns and base plate surround accommodation space, described first crossbeam be arranged in parallel with second cross beam and parallel with base plate, every first crossbeam is provided with at least two wing nut, the top of described wing nut connects second cross beam, drives second cross beam to move up and down along column by the turn of wing nut.
Preferably, every described first crossbeam is provided with two wing nuts.
In technique scheme, described parallel being located on described base plate of two groups of columns.
In technique scheme, the first crossbeam on described two groups of columns and base plate are equidistantly positioned.
In technique scheme, described base plate is provided with multiple locating dowel.
Preferably, described base plate is provided with six locating dowels.
