Description
Technical field
The present invention relates to integrated circuit field of tool, specifically a kind of four limit pin circuitry provisions for disengagement.
Background technology
Known, circuit module is that the interconnection that a kind of microcircuit module or microcircuit and discrete device are formed is combined, and this assembly is for realizing one or more electronic circuit functions and Design and manufacture; The circuit module of four limit pins, refers to four limits of the pin of circuit module in module.Four limit pins of circuit module are generally be welded on buck plate, once circuit module breaks down or lost efficacy, need circuit module to disassemble from buck plate to carry out analyzing or reprocessing.
Circuit module dismounting do over again generally adopt heat gun, repair workstation heats circuit, take out circuit module after making four side weld points fusings, or take out circuit module after adopting solder sucker to carry out detin process to each solder joint.Use heat gun heating dismounting, because heat gun discharge area is less, blowout hot blast area is little, cannot realize heating to four limit pins of circuit module simultaneously, dismounting difficulty.Repair workstation heats, that module whole is heated, some modular circuit sizes are larger, circuit thermal capacity is large, when module four limit pin melts soldering tin, the solder joint of the Surface Mount soldering components and parts in modular circuit also melts, and at this moment dismantles modular circuit, easily occurs Surface Mount soldering component shift in modular circuit or comes off.Adopt solder sucker to carry out detin process to each solder joint, need butt welding point heating for multiple times, easily occur Pad off.Therefore, the dismounting yield rate of circuit is extremely low.
Summary of the invention
The object of the present invention is to provide a kind of four limit pin circuitry provisions for disengagement, can be heated four limit pins of circuit by this device simultaneously, conveniently remove four limit pin circuitry, drastically increase the yield rate of circuit tear-down.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of four limit pin circuitry provisions for disengagement, comprise hot blast outer cover and the hot blast inner cover be located in hot blast outer cover, the open top of hot blast outer cover is rectangular or square, and the bottom of hot blast outer cover is provided with connecting hole; Hot blast inner cover bottom lock, open top is rectangular or square; The quadrangle hot-air mouth corresponding with circuit module four limit pin is formed between hot blast outer cover with hot blast inner cover; Hot blast outer cover is fixedly connected with by joint pin with hot blast inner cover; Described provision for disengagement also comprises branch sleeve, and one end of branch sleeve is fixedly connected with hot blast outer cover by connecting hole, and the air outlet of the other end and heat gun socket-connects.
Further, described hot blast inner cover is the infundibulate of bottom lock.
Further, described branch sleeve periphery is provided with the larynx hoop for being fastenedly connected.
The invention has the beneficial effects as follows, heated by the four limit pins of quadrangle hot-air mouth to circuit formed between hot blast outer cover and hot blast inner cover, conveniently disconnect circuit, drastically increases the yield rate of circuit tear-down simultaneously.
