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 through a series of encapsulation engineering.The semiconductor die package machined, will through electric checking engineering before being provided to user; In above-mentioned electric checking engineering, test jack is utilized to check the electrical specification of semiconductor die package.Here, test jack is the device direct loop electrical resistance of each semiconductor element be connected on testing tool.
Adding pressure type packaging and testing socket of the prior art is made up of upper cover, lateral support, low bottom-disc, fixed screw, shaft collar, pressurization disk, socket pin.During practical operation, first, the shaft collar being fixed with socket pin is connected with low bottom-disc by fixed screw.The lateral support of fixing encapsulation is also connected with low bottom-disc from the side.Between above-mentioned lateral support, encapsulation is put into above low bottom-disc.Apply pressure to above-mentioned encapsulation, the socket pin of above-mentioned socket and encapsulation ball are contacted, then covers pressurization disk and lid.
The adding pressure type packaging and testing socket with said structure, when Practical Project, in order to allow encapsulation and socket pin contact, applies pressure to pressurization disk; Because this project is manual operation, a certain size pressure therefore cannot be applied to pressurization disk.Therefore, the pressure of pressurization disk can be caused cannot to be communicated to sealing problem on the whole equably occur.In addition, in order to make above-mentioned encapsulation contact more securely with socket pin, often apply excessive pressure, the problem that socket pin wear resistance ratio therefore can be caused larger occurs.Therefore, have the growth of adding pressure type packaging and testing socket along with service time of said structure, due to abrasion and the uneven pressure of the indirection point of socket and encapsulation, above-mentioned contact state degenerates gradually, therefore tests bad probability and constantly increases.In addition, use seam or the upside-down mounting measure of fixed cover to apply pressure, in therefore testing, the process of ON/OFF lid, make the use of adding pressure type packaging and testing socket become not very convenient, and the time loss at this moment produced also add testing expense.
In order to solve the problems of the technologies described above, application number is that the application for a patent for invention of CN200410053915.5 discloses a kind of voltage reducing packaged test socket, is made up of following parts: the majority socket pin that the support component of fixing encapsulation contact with above-mentioned encapsulation, the support component fixing above-mentioned socket pin, above-mentioned socket pin and the pressure between encapsulating are reduced to the reliever of above-mentioned packaging and testing socket external pressure.Particularly, also comprise following parts in above-mentioned reliever: pipeline, be inserted in the space between above-mentioned socket pin; Propulsion system, provide power that inner air is externally flowed out by pipeline.Due to said structure, this invention utilizes the difference of the inside and outside air pressure of above-mentioned test jack, makes the contact of above-mentioned packaging and testing socket pin more stable, improves the efficiency of above-mentioned packaging and testing socket with this.
Summary of the invention:
Technical matters solved by the invention: voltage reducing packaged test socket of the prior art, space between socket pin and encapsulation must be confined space, reliever could by the pressure between socket pin and encapsulation lower than above-mentioned packaging and testing socket external pressure, this just needs the contact between the sidewall of encapsulation and the madial wall of socket to be close contact, so, require too high to encapsulation with coordinating between socket, be unfavorable for effectively carrying out of packaging and testing, be also unfavorable for the raising of packaging and testing efficiency.
