Because the lead-in wire pitch of the CQFP packaging part of 0.635mm, 0.5mm is very little, its lead-in wire is elongated " one " font; In order to ensure packaging part in the course of processing indeformable, be designed to tape insulation and connect the structure of muscle, surrounding design has the insulating frame of anchor leg. Requirement according to technique of integrated circuit packaging, ic package should carry out ageing test, will carry out ageing test and be accomplished by special socket. CQFP packaging part muscle, pitch≤0.8mm is connected for tape insulation, the problem such as processing and fabricating difficulty, test reliability not easily guarantee is there is with current ageing test jack, in order to ensure that tape insulation connects the product quality of the CQFP packaging part of muscle and the reliability of test, it is necessary to the ageing test jack of design specialized.
Summary of the invention
It is an object of the invention to provide a kind of ageing test jack with the floating bracket placing package leads; connect the construction features of muscle, pitch≤0.8mm CQFP packaging part and the actual demand of ageing test thereof meeting tape insulation; the structural design of this invention is easy to the placement of packaging part, location, and can tamper seal piece installing go between well in process of the test.
To achieve these goals, present invention employs following technical scheme:
The CQFP packaging part ageing test jack with floating bracket of the present invention, including cover plate and installing plate, cover plate is provided with rotating shaft mechanism with the side of installing plate and is connected so that socket capable of being rotated is opened; Opposite side is provided with fastening hook mechanism, and socket can be made to close;Contact chip is placed in the groove of installing plate, and position and quantity are corresponding with the lead-in wire of packaging part; It is characterized in that, the installing plate in socket is arranged over floating bracket to place packaging part.
The position of described floating bracket is corresponding with the lead-in wire of packaging part, for the ease of processing, quantitative design is female contact sheet (package leads) total quantity 1/4th of the groove that the square hole being placed into contact with end on floating bracket and placement can be gone between, one socket will assemble four identical floating brackets, surround square frame-shaped; The two ends of every floating bracket are provided with barb buckle, are passed down through hook hole corresponding on installing plate, and floating bracket can move up and down along hook hole; Being provided with spring between floating bracket and installing plate, it is simple to contact chip contact jaw and floating bracket move up and down, meet the needs of contact chip elastic deformation, after ensureing socket Guan Bi, contact chip can give the pressure that package leads is enough.
Inboard above floating bracket is provided with several grooves, corresponding with the lead-in wire of packaging part, and every lead-in wire is placed in groove; It is corresponding with the lead-in wire of packaging part that outside above floating bracket is provided with several square holes, each square hole size is all higher than the size of contact chip contact jaw, the contact jaw of contact chip is arranged in the square hole of floating bracket, after floating bracket fits down into position, the contact jaw of contact chip should be higher than that floating bracket, contacts with package leads.
When cover plate and installing plate Guan Bi, cover plate will be pressed under packaging part and floating bracket, and the package leads being positioned in groove contacts with the contact chip through floating bracket square hole, can give, by the elastic reaction of contact jaw, the pressure that package leads is enough.
The structure of the present invention has the following advantages and beneficial effect: has floating bracket to be easy to user by design and places packaging part, what this invention adopted is flip-shell (or gland-type) ZIF structure, this structure is convenient and swift in use, do not need specific purpose tool, simultaneously because devise floating bracket can well protect again IC-components, and it is easy to quick insertion and the feature extracted is very important in ageing is tested, locating slot in floating bracket can ensure that the reliable location of package leads, the contact jaw of each contact chip can be isolated by square hole in floating bracket equably, and increase creep age distance, ensure the insulating properties of product. this invention can be used for tape insulation and connects the ageing test of muscle, pitch≤0.8mm CQFP packaging part. by using checking, the performance indications of this product meet instructions for use.
