Disclosure of Invention
In order to solve the technical problems, the invention provides a DO-214 shearing force testing method, which changes a tensile force test into a shearing force test in a mode of testing the pushing of a poking piece and can effectively improve the testing precision and the testing efficiency.
The invention is realized by the following technical scheme.
The invention provides a DO-214 shear force testing method, which comprises the following steps:
A. clamping: a plurality of products to be tested packaged by DO-214 are arranged in a frame clamp;
B. pushing: pushing the frame fixture with the products to be tested to the test plectrum, so that at least one product to be tested on the frame fixture is aligned to the test plectrum;
C. pulling and cutting: the test shifting piece is shifted towards the direction of the product to be tested which is aligned with the test shifting piece, so that the test shifting piece pushes the upper part of the product to be tested to test;
D. repeating: and C, returning to the step B until all the products to be tested on the frame fixture are pushed by the test shifting piece.
And the products to be detected are assembled in a line on the frame clamp.
The products to be measured on the frame fixture are on the same straight line.
The product to be tested packaged by the DO-214 is a tube core of a DO-214 patch component.
The frame clamp is arranged on the test base and pushed.
The testing base is provided with a sliding groove, and the frame fixture is arranged in the sliding groove.
And in the step B, the product to be tested close to one end of the frame fixture is aligned to the test shifting piece, and the test shifting pieces are sequentially aligned one by one in the repeated process of the step D.
The products to be tested are arranged in the frame fixture, and the products to be tested are independently fixed and do not interfere with each other.
The invention has the beneficial effects that: by dividing the frame, the interaction force among other products can be effectively avoided when the data of one product is tested, so that the test data is more accurate; the product data are measured in sequence by adopting a mode of moving the frames left and right to load the boxes, so that the traditional complicated test method is solved, each frame can be finished in one go, and the operation is more convenient; it is suitable for all types of shear force testers.

Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
The basic operation principle of the invention is shown in fig. 1, and the specific operation comprises the following steps:
A. clamping: a plurality of products to be tested 1 packaged by DO-214 are arranged in a frame clamp 3;
B. pushing: pushing the frame fixture 3 with the product 1 to be tested to the test plectrum 2, so that at least one product 1 to be tested on the frame fixture 3 is aligned to the test plectrum 2;
C. pulling and cutting: the test shifting piece 2 is shifted towards the direction of the product 1 to be tested which is aligned with the test shifting piece 2, so that the test shifting piece 2 pushes the upper part of the product 1 to be tested to test;
D. repeating: and returning to the step B until all the products 1 to be tested on the frame fixture 3 are pushed by the test poking piece 2.
As shown in fig. 2, the products 1 to be tested are assembled in a line on the frame fixture 3, the products 1 to be tested on the frame fixture 3 are in the same line, and the products 1 to be tested are independently fixed without interference.
The product 1 to be tested packaged by the DO-214 is a die of a DO-214 patch component, typically a DO-214 patch diode die.
