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 chip packaging 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 chip packaging.Herein, test jack is that the direct circuit of each semiconductor element is electrically connected
Device on to test equipment.
Adding pressure type packaging and testing socket of the prior art is by upper cover, lateral support, low bottom-disc, fixed screw, fixation
Disk, pressurization disk, socket needle composition.During practical operation, first, the fixation disk for being fixed with socket needle 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 needle 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 above structure is in Practical Project, in order to which encapsulation and socket needle is allowed to connect
It touches, applies pressure to pressurization disk；Since the engineering is manual operation, no normal direction pressurization disk applies a certain size pressure.
Therefore, the problem of causing the pressure of pressurization disk that can not equably be passed to sealing on the whole, occurs.In addition, in order to make above-mentioned envelope
Dress and socket needle more securely contact, and often apply excessive pressure, therefore socket needle can be caused to wear away the problem of bigger
Occur.Therefore, the adding pressure type packaging and testing socket with above structure is with the growth of usage time, due to socket and encapsulation
The abrasion of indirection point and non-uniform pressure, above-mentioned contact state gradually degenerate, therefore test bad probability and constantly increase.Separately
Outside, in order to apply pressure using the fixed seam of lid or upside-down mounting measure, thus in testing ON/OFF lid process, make
The use of adding pressure type packaging and testing socket becomes not very convenient, and the time loss at this moment generated also adds test fee
With.
In order to solve the above-mentioned technical problem, application No. is the applications for a patent for invention of CN200410053915.5 to disclose one kind
Voltage reducing packaged test socket is made of following component：The support member of fixed encapsulation, the majority contacted with above-mentioned encapsulation
Pressure between above-mentioned socket needle and encapsulation is reduced to above-mentioned encapsulation survey by a socket needle, the support member of fixed above-mentioned socket needle
Try the decompressor of socket external pressure.Particularly, following component is further included in above-mentioned decompressor：Pipeline is inserted into
In space between above-mentioned socket needle；Power plant, providing power makes inner air pass through pipeline to outside outflow.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 needle more
Add stable, the efficiency of above-mentioned packaging and testing socket is improved with this.
In the prior art, the hold-down devices of receipts formula can be stretched by increasing in encapsulation on the basis of said program, so as to
The gap size between encapsulation and the side wall of square box can be ignored, it is possible to appropriate to increase this gap to facilitate staff
BGA package is picked and placeed, to improve the efficiency of packaging and testing.But the start of this protocol questions, i.e. hold-down devices passes through work
Personnel adjust operation post to reach one by one, and this adds increased the work of staff, are unfavorable for the raising of the efficiency of packaging and testing.
