Description
This application is a divisional application of the patent application with application number 201610129907.7.
The technical field is as follows:
the invention relates to a test tool of a chip, in particular to a BGA packaging test socket.
Background art:
semiconductor components are processed through a series of packaging processes into semiconductor chip packages. A finished semiconductor chip package that is subjected to an electrical inspection process before being provided to a customer; in the electrical inspection process, the electrical characteristics of the semiconductor chip package are inspected using the test socket. Here, the test socket is a device that electrically connects the direct loop of each semiconductor element to the test instrument.
The pressurized package test socket in the prior art is composed of an upper cover, a side support piece, a lower chassis, a fixing screw, a fixing disc, a pressurizing disc and a socket pin. In actual operation, first, the fixing plate fixed with the socket needle is connected with the lower chassis through the fixing screw. Side supports that secure the package from the sides are also connected to the lower chassis. The package is placed over the lower tray through between the side supports. And applying pressure to the package to make the socket pins of the socket contact with the package balls, and then covering the pressure plate and the cover.
In the actual engineering, the pressure type packaging test socket with the structure applies pressure to the pressure plate in order to enable the packaging to be in contact with the socket needle; since this process is a manual operation, a certain amount of pressure cannot be applied to the pressure plate. Therefore, the pressure of the pressure plate cannot be uniformly transmitted to the entire seal. In addition, in order to make the package and the socket pin contact more firmly, an excessive pressure is applied, and thus a problem of relatively large abrasion of the socket pin arises. Therefore, as the time of use of the pressure type package test socket having the above-described structure increases, the contact state gradually deteriorates due to abrasion and uneven pressure of the contact between the socket and the package, and thus the probability of defective test increases. In addition, the use of a seam for fixing the cover or a flip-chip measure for applying pressure, and thus the process of opening/closing the cover during testing, makes the use of the pressurized package test socket inconvenient, and the time loss generated at this time increases the test cost.
In order to solve the above technical problem, the invention patent application with application number CN200410053915.5 discloses a decompression type package test socket, which is composed of the following components: the socket comprises a supporting component for fixing a package, a plurality of socket pins contacted with the package, a supporting component for fixing the socket pins, and a pressure reducing device for reducing the pressure between the socket pins and the package to the external pressure of the package test socket. In particular, the pressure reducing device further comprises the following components: a tube inserted into a space between the socket needles; and the power device provides power to enable the internal air to flow out through the pipeline. Due to the structure, the invention utilizes the difference between the internal air pressure and the external air pressure of the test socket to ensure that the package is more stably contacted with the test socket needle, thereby improving the efficiency of the package test socket.
In the prior art, on the basis of the scheme, the extensible pressing device is additionally arranged on the package, so that the size of a gap between the package and the side wall of the square frame can be ignored, and the gap can be properly increased to facilitate a worker to take and place the BGA package, so that the efficiency of package testing is improved. However, the problem of the scheme is that the actuation of the pressing device is achieved by adjusting the operation columns one by a worker, so that the work of the worker is increased, and the improvement of the efficiency of the packaging test is not facilitated.
