Abstract
The invention discloses a computer test chip installation method. A top fixed plate is fixed on a test base; a gap plate is fixed on the top fixed plate; a test plate is located by a pin, the front end is fixed on the gap plate through a screw, and the rear end is fixed on the top fixed plate through a screw; a socket is located on the test plate through a pin; a resin block is located on the test plate through a pin, and is fixed on the test plate through screws; and the socket is fixed on the resin block through screws. The computer test chip installation method has the advantage that the installation accuracy is improved, the installation speed and difficulty are greatly reduced, the stability of test is guaranteed, and the service life of a gold pin in the socket is greatly increased.
Description
Technical field
The present invention relates to a kind of chip mounting method.
Background technology
Existing computer testing chip, its test board is contained on gapplate with screw, socket has accurate location with alignment pin and test board, fixedly to be screwed on gapplate, because be greater than the external diameter of screw through the hole of screw, need the absolute centering in center, installation difficulty is larger, contact acupuncture needle is easy to be subjected to displacement in installation process, affects measuring accuracy.
Summary of the invention
Goal of the invention: for the problems referred to above, the object of this invention is to provide a kind of installation method of computer testing chip, solve the orientation problem of test board and gapplate, and the fixation problem of socket.
Technical scheme: a kind of installation method of computer testing chip, top fixed head is fixed in testing base, gapplate is fixed on the fixed head of top, test board is located by pin, and it is upper that front end is screwed in gapplate, and rear end is screwed on the fixed head of top, socket is positioned on test board by pin, resin mass is positioned on test board by pin, is screwed on test board, and socket is screwed on resin mass.
Test board and top fixed head are the bearing pin location with 4k6, and the fit tolerance of test board and bearing pin is 4H7/k6.
Beneficial effect: compared with prior art, advantage of the present invention is that installation accuracy improves, and installation rate and difficulty reduce greatly, have ensured the stability of test, and greatly increase the service life of socket the inside acupuncture needle.
Detailed description of the invention
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present invention.
Existing test board and test bench locating mounting method are: on test board, hole size is 3.6 circular troughs, coordinate with M3 screw, and M3 screw external diameter is 3, thus test board transversely maximum have 2mm displacement, longitudinally going up maximum has 0.6mm displacement; Gapplate can not accurately locate, and socket just can not accurately locate.
Test board of the present invention and test bench locating mounting method are: top fixed head is fixed in testing base, gapplate is fixed on the fixed head of top, test board is located by pin, front end is screwed on gapplate, rear end is screwed on the fixed head of top, and socket is positioned on test board by pin, and resin mass is positioned on test board by pin, be screwed on test board, socket is screwed on resin mass.
Test board and top fixed head are the bearing pin location with 4k6, and the fit tolerance of test board and bearing pin is 4H7/k6, and tolerance range is:
Maximal clearance Smax=Dmax-dmin=0.012-0.001=0.011
Minimum clearance Smin=Dmin-dmax=0-0.009=-0.009
Fit tolerance Tf=Smax-Smin=0.011+0.009=0.02
The fit tolerance of Socket and bearing pin is 1.588H7/k6, and tolerance is close to zero.
The fit tolerance of test board and resin mass is 1.5H7/k6, and tolerance is close to zero.
The allowance control of test bench socket, within 0.02 scope, meets Production requirement.
The location of test board of the present invention is by original 2mm, within tapering to 0.02mm, do not consider the position error of pcb plate, the positional precision of socket has been controlled within 0.01mm scope, installation difficulty also greatly reduces, often fill a test board and all will adjust the centering of test board by original, and then adjust the centering of socket, till now if dress screw just can.
Claims (2)
1. the installation method of a computer testing chip, it is characterized in that: top fixed head is fixed in testing base, gapplate is fixed on the fixed head of top, test board is located by pin, and it is upper that front end is screwed in gapplate, and rear end is screwed on the fixed head of top, socket is positioned on test board by pin, resin mass is positioned on test board by pin, is screwed on test board, and socket is screwed on resin mass.
2. the installation method of a kind of computer testing chip according to claim 1, is characterized in that: test board and top fixed head are the bearing pin location with 4k6, and the fit tolerance of test board and bearing pin is 4H7/k6.
