Description

Four-spliced in-line chip test fixture

Technical Field

The utility model relates to a chip test technical field specifically is a four pieces together in line chip test fixture.

Background

Chip production requires hundreds of processes, and errors in any one step can cause device failure, so chip detection becomes more and more important, and the adoption of good chip testing equipment and a good chip testing method is the key for improving the chip manufacturing level. Common chip detection tool can only detect one or two chips generally once, and detection efficiency is low, and the chip does not have overvoltage protection placing the in-process moreover, and the excessive pressure often appears and leads to the chip to be crushed wounded, crush, causes very big waste.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a four piece together in line chip test fixture to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a four pieces together and arrange chip test fixture in line, includes the base, the upper portion of base is equipped with the chip groove, first response groove, second response groove have been seted up respectively in the middle of the front and back both sides in chip groove, first response groove, chip groove, second response groove are linear arrangement and run through on the base from beginning to end, the degree of depth in first response groove and the degree of depth inequality in second response groove.

Further preferably, the base is connected to the test machine table through a gasket and a screw.

Preferably, the chip grooves are formed by four same structures which are uniformly arranged on the base in a straight line, and each chip groove is correspondingly provided with an induction groove.

Further preferably, the base is provided with first pins, the first pins are designed in a circular truncated cone step shape, and the first pins are four parts arranged on the base.

Further preferably, the bottom of the middle of the chip groove is provided with a through hole which is connected with a tester.

Further preferably, the bottom of the base is provided with four second pins which are respectively arranged at four corners of the base.

Advantageous effects

The utility model discloses a four piece together in line chip test fixture through first pin guide location, can guarantee that the chip places accurately, can not appear crushing, and four chip grooves can be tested four chips simultaneously, and chip test efficiency is high, and this tool simple structure, the production of being convenient for.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Examples

As shown in fig. 1-2, a four-spliced in-line chip testing jig comprises a base 1, wherein a chip groove 4 is formed in the upper portion of the base 1, a first induction groove 2 and a second induction groove 3 are respectively formed in the middle of the front side and the rear side of the chip groove 4, the first induction groove 2, the chip groove 4 and the second induction groove 3 are linearly arranged and penetrate through the base 1 from front to rear, and the depth of the first induction groove 2 is not equal to that of the second induction groove 3.

Preferably, first response groove 2 and the 3 degree of depth of second response groove vary, form the dislocation connection, and be connected with the inductor, the inductor can be based on sensing chip slot 4 on the chip position and make the contrast, judge whether the chip is placed in place, whether crooked appears, can sense simultaneously whether there is the chip in the chip slot 4.

Preferably, the base 1 is connected to the testing machine through a gasket 6 and a screw 7, and the base 1 is fixed through two screws 7.

Preferably, chip groove 4 is that four looks isostructures are sharp align to grid on base 1, and every chip groove 4 all corresponds and is equipped with the response groove, can test four chips simultaneously, improves detection efficiency.

Preferably, be equipped with first pin 5 on the base 1, first pin 5 adopts the design of round platform class type, first pin 5 is four to divide and locates on the base 1, can prevent that transmission structure from putting into or taking out the chip from chip groove 4 the time, and the too big chip that weighs wounded of down distance, and first pin 5 plays the effect of location simultaneously, and the guide transmission structure accuracy is placed the chip.

Preferably, the middle bottom of the chip slot 4 is provided with a through hole, and the through hole is connected with a tester.

Preferably, the bottom of the base 1 is provided with four second pins 8, which are respectively arranged at four corners of the base 1 to achieve a positioning effect on the base 1.

The four corners of the chip groove 4 are provided with abdicating holes to prevent the chip from being damaged when the chip is put into or taken out of the chip groove 4.

The utility model discloses a chip test fixture places the chip in chip groove 4 through transmission structure and detects, is equipped with the response groove on the base 1, guarantees that the chip places the accuracy, and first pin 5 plays the protection to the chip simultaneously, and four chips can be placed simultaneously in four chip grooves 4 and test, and efficiency of software testing is high.
