Abstract

The invention relates to a method for checking and accepting a substrate online testing tool. The method comprises that: a plurality of gauge pins are glued into a groove of an upper plate or a lower plate of the tool, and the height of the gauge pins is 0.2 millimeter lower than the depth of the groove; a piece of sensing paper is arranged on a standard substrate; and when the upper plate and the lower plate of the tool are pressed in, whether a testing needle can bend the substrate by more than 0.2 millimeter is judged by whether impressions of the gauge pins are left on the sensing paper. The check and acceptance method can accurately detect whether the pressure of the testing needle can bend the substrate by more than 0.2 millimeter so as to prevent unqualified substrate online testing tools from flowing into a testing production line and causing damage of substrates or making test results have deviation.

Description

The acceptance method of substrate on-line test tool

Technical field

The present invention relates to a kind of test acceptance method, especially relate to the acceptance method of a kind of substrate on-line performance or functional test tool, be mainly used in when checking and accepting new substrate on-line test tool, judge its substrate that when test, whether can bend.

Background technology

When being used for substrate on-line test, substrate on-line test tool compresses substrate, because on the surface of substrate components and parts are arranged, the upper plate of measurement jig or lower plate are provided with the groove of dodging components and parts, when the upper plate of measurement jig and lower plate are pushed down substrate, because the pressure of testing needle, substrate may bend at the groove of upper plate or lower plate, and when curved substrate surpasses 0.2 millimeter, just may cause substrate damage or make test result produce deviation.At present, checking and accepting according to the following steps usually for new tool:

1. the upper plate and the lower plate of new tool are pushed down standard substrate;

2. whether the mode validation criteria substrate with range estimation is crooked.Above-mentioned acceptance method only can detect the new tool that causes the standard substrate degree of crook bigger, for the new tool that causes the standard substrate bending near 0.2 millimeter, be difficult to confirm, cause defective tool to flow into production line, thereby cause substrate damage or make test result produce deviation with the mode of range estimation.

Whether the applicant has carried out research and has improved at above-mentioned problem, and a kind of substrate on-line test tool acceptance method is provided, can accurately detect substrate on-line test tool and can cause curved substrate to surpass 0.2 millimeter.

Summary of the invention

In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:

A kind of acceptance method of substrate on-line test tool may further comprise the steps:

Step 1. is selected corresponding amount post, low 0.2 millimeter of the degree of depth of the aspect ratio groove of this amount post according to the degree of depth of substrate on-line test tool upper plate or lower plate groove;

Step 2. is selected and the identical induction paper of standard substrate size;

Step 3. determines amount post placement location and quantity according to the position of substrate on-line test tool upper plate or lower plate groove and size, and will measure post and be bonded at substrate on-line test tool upper plate or lower plate with bonding agent

Step 4. is respectively installed to substrate on-line test tool upper plate and lower plate on the last anchor clamps and platform of testing apparatus;

Step 5. is placed on standard substrate on the substrate on-line test tool lower plate, and places induction paper on standard substrate;

Step 6. starts testing apparatus, and substrate on-line test tool upper plate and lower plate are pressed together;

Step 7. starts testing apparatus once more, lift the substrate on-line test tool upper plate, take out induction paper, as respond to and have the position of place's corresponding amount post that impression is arranged on the paper, judge that then this substrate on-line test tool is defective, as the position of responding to corresponding amount post on the paper do not have impression, and then this substrate on-line test tool of decidable is qualified.

Technique effect of the present invention is:

The acceptance method of a kind of substrate on-line test tool disclosed in this invention, whether the pressure that can accurately detect testing needle can cause the bending of substrate to exceed 0.2 millimeter, avoids underproof substrate on-line test tool to flow into the test production line and causes substrate damage or make test result produce deviation.

Embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.

As shown in Figure 1, 2, a kind of substrate on-line test tool, its upper plate 1 is provided with the groove 6 of dodging components and parts, and the degree of depth of groove 6 is A, does not have groove on the lower plate 2.Follow these steps to check and accept this substrate on-line test tool:

Step 1. is selected corresponding amount post according to the degree of depth A of substrate on-line test tool upper plate groove, low 0.2 millimeter of the degree of depth A of the aspect ratio groove of this amount post B.

Step 2. is selected and the identical induction paper 5 of standard substrate 3 sizes, standard substrate 3 is the benchmark whether test base on-line testing tool can cause curved substrate, its surfacing and do not have thrust, it is 0.02 millimeter that its flatness requires, and what the induction paper 5 in the present embodiment used is the 4LWC FILM/4LW A FILM induction paper of FUJIFILM brand.

Step 3. is determined placing 6 amount posts 4 (respectively placing 3 amount posts 4 in the groove 6 of upper plate 1 both sides) as the position among Fig. 2 according to the position and the size of substrate on-line test tool upper plate 1 groove 6, and will measure groove 6 places that post 4 usefulness bonding agents are bonded at the substrate on-line test tool upper plate.The placement location of amount post 4 and quantity can be determined according to the position and the size of substrate on-line test tool upper plate or lower plate groove.

Step 4. is respectively installed to substrate on-line test tool upper plate 1 and lower plate 2 on the last anchor clamps 7 and platform 8 of testing apparatus.

Step 5. is placed on standard substrate 3 on the substrate on-line test tool lower plate 2, and places induction paper 5 on standard substrate 3.

Step 6. starts testing apparatus, substrate on-line test tool upper plate 1 and lower plate 2 are pressed together, this moment, testing needle 9 was pressed on the standard substrate 3, it is crooked that the pressure of testing needle 9 may cause standard substrate 3 to produce at groove 6 places, if crooked above 0.2 millimeter, crooked standard substrate 3 amount of pressing to posts 4, thus stay impression in the position of induction paper 5 respective amount posts 4, be no more than 0.2 millimeter as bending, the position of then responding to paper 5 respective amount posts 4 does not have impression.

Step 7. starts testing apparatus once more, lift substrate on-line test tool upper plate 1, take out induction paper 5, as respond to and have the position of place's corresponding amount post that impression is arranged on the paper 5, judge that then this substrate on-line test tool is defective, as the position of responding to the corresponding amount post on the paper do not have impression, and then this substrate on-line test tool of decidable is qualified.

Above-mentioned acceptance method is equally applicable to all examinations of reeded substrate on-line test tool of fluted or upper and lower plate on the lower plate.
