Problems solved by technology

[0002] The existing vertical flying probe testing machine can only test PCB boards with a certain thickness and rigidity, and cannot accurately test PCB boards that are relatively thin and soft, thin and easy to fold, or the measuring point is close to the edge of the board, and the direct measurement is caused by the shaking of the PCB board. Or poor fixture splints will lead to missing tests and false test points. Only one-sided measurement can make the conductivity between the layer hole walls impossible to measure and inefficient, and it is impossible to make accurate judgments on product quality.

Embodiment Construction

[0020] The present invention will be further elaborated below in conjunction with accompanying drawing, please refer to figure 1 .

[0021] A kind of PCB sheet vertical flying probe test support frame, it is characterized in that: comprise support frame body 1, described support frame body is located on PCB board surface, is provided with for probe to pass through support frame body and The through hole 2 contacted by the pad or via hole on the PCB; the number of the through hole is the same as the total number of the pad and the via on the PCB; the length of the through hole is greater than the length of the through hole, and the length of the through hole The width is greater than the width of the through hole; the material of the support frame body is FR-4 insulating material.

[0022] The manufacturing method of support frame body of the present invention is:

[0023] a. Measure the PCB size to obtain the length and width data of the PCB; then take the entire FR-4 insula...

Abstract

The invention relates to a PCB thin board vertical flying probe test bracing frame. The PCB thin board vertical flying probe test bracing frame comprises a bracing frame body, wherein the bracing frame body is arranged on a PCB surface, and the bracing frame is provided with through holes enabling probes penetrating through the bracing frame body to contact with a welding pad on a PCB or passage openings. Through the additionally-equipped PCB thin board vertical flying probe test bracing frame, the thin board is supported and is prevented from shaking, test points at a back surface can be further exposed, dual-surface simultaneous detection is realized, test accuracy is improved, a test yield is improved, and an electric measurement operation board loss rate can be reduced; the bracing effect of the bracing frame is excellent, dual-surface measurement and full-measurement-point measurement of 0.05-0.10mm thin boards are realized, measurement reliability is improved, and PCB flying probe test efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of industrial automation, in particular to a PCB sheet vertical flying probe test support frame. Background technique [0002] The existing vertical flying probe testing machine can only test PCB boards with a certain thickness and rigidity, and cannot accurately test PCB boards that are relatively thin and soft, thin and easy to fold, or the measuring point is close to the edge of the board, and the direct measurement is caused by the shaking of the PCB board. Or poor fixture splints will lead to missing tests and false test points. Only one-sided measurement can make the conductivity between the layer hole walls impossible to measure and inefficient, and it is impossible to make accurate judgments on product quality. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a PCB sheet vertical flying probe test support frame. [0004] The technical scheme that ...
