Description
Technical field：
The present invention relates to the testing tool of chip, in particular to a kind of BGA package test jack.
Background technology：
Semiconductor element is processed to semiconductor die package by a series of encapsulation engineerings.The semiconductor core machined
Piece encapsulates, and to pass through electric checking engineering before providing to user；In above-mentioned electric checking engineering, test jack inspection is utilized
The electrical characteristic of semiconductor die package.Herein, test jack is that the direct loop of each semiconductor element is electrically connected
Device on to tester.
Adding pressure type packaging and testing socket of the prior art is by upper lid, lateral support, low bottom-disc, fixed screw, fixation
Disk, pressurization disk, socket pin composition.During practical operation, first, the fixed disk for being fixed with socket pin passes through fixed screw and low bottom-disc
It is connected.The lateral support that encapsulation is fixed from side is also connected with low bottom-disc.By the way that between above-mentioned lateral support, encapsulation is put
Above to low bottom-disc.Apply pressure to above-mentioned encapsulation, the socket pin and encapsulation ball for making above-mentioned socket are in contact, and then cover pressurization
Disk and lid.
Adding pressure type packaging and testing socket with said structure is in Practical Project, in order to allow encapsulation and socket pin to connect
Touch, apply pressure to pressurization disk；Because the engineering is manual operation, therefore apply a certain size pressure without normal direction pressurization disk.
Therefore, the problem of pressure of pressurization disk can be caused can not to be equably communicated to sealing on the whole, occurs.In addition, in order that above-mentioned envelope
Dress and socket pin are more securely contacted, and often apply excessive pressure, therefore socket pin can be caused to wear away the problem of bigger
Occur.Therefore, the adding pressure type packaging and testing socket with said structure is with the growth of usage time, due to socket and encapsulation
The abrasion of indirection point and uneven pressure, above-mentioned contact state gradually degenerate, therefore test bad probability and constantly increase.Separately
Outside, in order to apply seam or upside-down mounting measure of the pressure using fixed lid, thus in testing ON/OFF lid process, make
The use of adding pressure type packaging and testing socket becomes not very convenient, and this caused time loss also add test fee
With.
In order to solve the above-mentioned technical problem, Application No. CN200410053915.5 application for a patent for invention discloses one kind
Voltage reducing packaged test socket, it is made up of following part：The support member of fixed encapsulation, the majority contacted with above-mentioned encapsulation
Individual socket pin, fixed above-mentioned socket pin support member, the pressure between above-mentioned socket pin and encapsulation be reduced to above-mentioned encapsulation surveyed
Try the decompressor of socket external pressure.Particularly, following part is also included in above-mentioned decompressor：Pipeline, it is inserted into
In space between above-mentioned socket pin；Power set, there is provided power makes inner air be flowed out by pipeline to outside.Due to above-mentioned
Structure, the invention utilize the difference of the inside and outside air pressure of above-mentioned test jack, make the contact of above-mentioned packaging and testing socket pin more
Add stable, the efficiency of above-mentioned packaging and testing socket is improved with this.
The content of the invention：
Technical problem solved by the invention：Voltage reducing packaged test socket of the prior art, socket pin and encapsulation
Between space must be confined space, the pressure between socket pin and encapsulation could be less than above-mentioned packaging and testing socket by decompressor
External pressure, this just needs the contact between the madial wall of the side wall and socket encapsulated to be in close contact, in this way, to encapsulation and inserting
Cooperation between seat requires too high, is unfavorable for effective progress of packaging and testing, is also unfavorable for the raising of packaging and testing efficiency.
