Description
Technical field
This utility model is related to a kind of both sides pin package burning chip test station structure, belongs to burning chip equipment skill
Art field.
Background technology
When chip of the pin positioned at plastic-sealed body two ends carries out burning or test in automatization or semi-automatic board, it is logical
Cross golden finger or acupuncture needle is contacted with chip pin, realize the connection of chip and cd-rom recorder, so that burning test is carried out to chip.
Traditional die burning test station structure makes golden finger bending and chip both sides pin order by pressing golden finger
Contact.The problem that this structure is present is that golden finger is difficult to ensure that uniform force when pressing to pin both sides, if burning test rail
Road produces leaky as pin discontinuity causes pin easily to touch track using during metal material；And use non-gold
Category insulant, is all difficult to keep because frequently making work, the mechanical strength of track and life-span.Meanwhile, it is to ensure burning test
Quality, traditional station structure are higher to the requirement on machining accuracy of track, cause production cost high, and track be also limited to it is right
The burning test of the both sides pin package chip of different size thickness.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of both sides pin package chip burns
Record test station structure, simple structure ensure that both sides pin uniform force.
According to this utility model provide technical scheme, the both sides pin package burning chip test station structure, its
It is characterized in that：Including pan feeding track, the base pressure bar that can make rise and fall action is arranged in pan feeding rail base, directly over base pressure bar
Be chip in pan feeding track enters discharge position；Overhead gage is set above the pan feeding track, multiple leading in overhead gage, is worn
Bar, guide rod are slidably matched with overhead gage, and the top of guide rod arranges limited cap, and spring is arranged between limited cap and overhead gage；Institute
State.
Further, it is provided for blocking the chip baffle plate of chip on front side of the base pressure bar.
Further, the plurality of guide rod is centrosymmetric setting with the center of base pressure bar.
This utility model pan feeding track bottom be arranged installation base pressure bar, by base pressure bar drive chip on move and with gold
Finger is contacted, and can fundamentally avoid the generation of metal material track leaky caused by chip pin unbalance stress；This
Utility model is also by being symmetrical arranged spring retainer bar on the upside of overhead gage, it is ensured that chip be with transposing contact golden finger in level,
Uniform force when chip pin can be made to press to golden finger, both benign contacts improve the burning detection quality of chip；This reality
The thickness specification of the machining accuracy and chip of track is not limited to new structure, simple structure can largely reduce life
Produce cost.

Specific embodiment
With reference to concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to 4：The both sides pin package burning chip test station structure include limited cap 1, guide rod 2,
Spring 3, overhead gage 4, golden finger 5, chip 6, base pressure bar 7, chip baffle plate 8, pan feeding track 9 etc..
As shown in FIG. 1 to 3, both sides pin package burning chip test station structure described in the utility model, including entering
Material track 9, is arranged installation base pressure bar 7 in 9 bottom of pan feeding track, is the entering in pan feeding track 9 of chip 6 directly over base pressure bar 7
Discharge position；Overhead gage 4 is set above the pan feeding track 9, and the left-right and front-back of overhead gage 4 wears guide rod 2 respectively, guide rod 2 with
Overhead gage 4 is slidably matched, and the top of guide rod 2 arranges limited cap 1, and spring 3 is arranged between limited cap 1 and overhead gage 4；In the core
Golden finger 5 is respectively provided with above the both sides of piece 6；It is provided for blocking the chip baffle plate 8 of chip 6 in the front side of the base pressure bar 7.
Operation principle of the present utility model：Chip 6 is slipped to the golden finger 5 of pan feeding track 9 by chip by pan feeding track
Baffle plate 8 is blocked, and is then moved on base pressure bar 7, is made 6 upper surface of chip be close to overhead gage 4（As shown in Figure 4）, when chip 6 and overhead gage
After 4 contacts, move in the continuation of base pressure bar 7, chip 6 and overhead gage 4 is moved on the whole, be now placed in the spring 3 on the upside of overhead gage 4 and open
Begin to compress, make 4 upper surface of overhead gage be subject to 3 pressure of uniform spring, so that moving in 4 holding level of chip 6 and overhead gage straight
To chip 6 both sides pin contact with golden finger 5 after stop the upper mobile of base pressure bar 7 and make, now, pin is with golden finger 5
Smoothly connect, start burning test job.
This utility model pan feeding track bottom be arranged installation base pressure bar, by base pressure bar drive chip on move and with gold
Finger is contacted, and can fundamentally avoid the generation of metal material track leaky caused by chip pin unbalance stress；This
Utility model is also by being symmetrical arranged spring retainer bar on the upside of overhead gage, it is ensured that chip be with transposing contact golden finger in level,
Uniform force when chip pin can be made to press to golden finger, both benign contacts improve the burning detection quality of chip；This reality
The thickness specification of the machining accuracy and chip of track is not limited to new structure, simple structure can largely reduce life
Produce cost.
