Description

Technical Field

[0001] The utility model relates to the technical field of water break test, and particularly relates to a device for water film test of copper clad laminates. Background Art

[0002] In the production process of printed circuit boards, it is necessary to conduct a water break test on the copper clad laminate that has been brushed, polished and dried to evaluate the surface roughness of the copper clad laminate. That is, before the dry film process, a water film test needs to be carried out on each board, and manual inspection is required. After the copper clad laminate is immersed in water and taken out, it is placed at an angle of 45°. If the water film can remain unbroken for more than 15 seconds, it means that the grinding of the board is qualified. However, if it is unqualified, the test needs to be repeated, and the inspection process needs to be verified repeatedly, which is rather troublesome. Moreover, the existing test environment for water film test fails to be consistent during the test, resulting in low accuracy of the test results.

[0003] Therefore, this application proposes a technical solution to solve the above problems. Content of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a device for water film test of copper clad laminates, which can improve the accuracy of test results. At the same time, it can also reduce the labor intensity of technicians, and has a simple and practical structure.

[0005] A device for water film test of copper clad laminates according to an embodiment of the utility model includes:

[0006] A support frame, which is composed of a first support, a second support and a third support connected end to end. The first support and the second support are arranged at an angle of 45°. A support part is provided on the side of the first support away from the second support, and the support part is used to place the plate to be detected.

[0007] A humidifying mechanism, including a spray head, which can provide a water mist covering the support frame to provide an environmental humidity meeting the test requirements for the plate to be detected.

[0008] An apparatus for testing the water film on copper-clad laminates according to an embodiment of this utility model has at least the following beneficial effects: A nozzle sprays water mist, placing the support frame in an environment with a certain humidity. The copper-clad laminate to be tested is then placed on the support frame. Specifically, the bottom of the copper-clad laminate to be tested rests against the support, and the surface rests against the first bracket, ensuring the board is stable and will not slip. The formation of the water film on the surface of the board is then observed. After the nozzle continuously sprays for a period of time, such as 15 seconds, a uniform water film is observed on the surface of the board. Once the water film forms on the board surface, the tester simultaneously observes and records whether the board exhibits water breakage and the changes in the water film during a specific time period (e.g., 15 seconds). If the water film on the board surface breaks during the test time, the board is considered unqualified; if the water film does not break during the test time, the board is considered qualified. At the same time, while the nozzle forms a water film on the surface of the board, it can also provide a certain humidity testing environment for the board, ensuring that the testing environment for boards of the same model is the same, thus ensuring the consistency of the test results.

If the terms "first" and "second" are used, they are merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figure 1 This utility model provides an apparatus for water film testing of copper-clad laminates, including a support frame, which consists of a first bracket 100, a second bracket 200, and a third bracket 300 connected end to end. The first bracket 100 and the second bracket 200 are set at a 45° angle. A support part is provided on the side of the first bracket 100 away from the second bracket 200, and the support part is used to place the board to be tested. A humidification mechanism includes a nozzle 400, which can provide water mist to cover the support frame and provide the board to be tested with an environmental humidity that meets the testing requirements.

[0034] The nozzle 400 sprays water mist, creating a humid environment for the support frame. The copper-clad laminate to be tested is then placed on the support frame, specifically with its bottom resting against the support and its surface against the first bracket 100, ensuring stability and preventing slippage. The formation of a water film on the surface of the laminate is then observed. After the nozzle 400 sprays continuously for a period of time, such as 15 seconds, a uniform water film is observed on the surface of the laminate. Once the water film forms, the tester simultaneously observes and records whether any water fracturing occurs and records the changes in the water film over a specific time period (e.g., 15 seconds). If the water film on the surface of the laminate breaks during the test, the laminate is considered unqualified; if the water film does not break during the test, the laminate is considered qualified. At the same time, the nozzle 400 can form a water film on the surface of the board while providing a certain humidity testing environment for the board, ensuring that the testing environment of boards of the same model is the same, so as to ensure the consistency of test results.

[0035] According to some embodiments of this application, two support frames are arranged side by side, which can improve the support stability of the plate.

[0036] According to some embodiments of this application, a support rod 110 is provided at one end of a bracket near the second bracket 200. One end of the support rod 110 is fixedly connected to the first bracket 100, and the other end extends toward the end away from the first bracket 100. The support rod 110 is a support part.

[0037] According to some embodiments of this application, a support frame is disposed within a receiving pool 500, which is filled with a test solution. Furthermore, the liquid level in the receiving pool 500 is maintained below the support to prevent the solution from soaking into the surface of the plate and affecting the test results, thus ensuring the accuracy of the test.

[0038] Furthermore, the humidification mechanism also includes a water supply assembly, which comprises a pump 600 and a connecting pipe 700. The pump 600 is disposed within the receiving tank 500, and one end of the connecting pipe 700 is connected to the water outlet of the pump 600. A nozzle 400 is connected to the water outlet of the connecting pipe 700. Specifically, the connecting pipe 700 is perpendicular to the receiving tank 500, and the nozzle 400 is disposed above the support frame via the connecting pipe 700. Optionally, the connecting pipe 700 is a telescopic pipe, allowing the nozzle 400 to be moved away from or closer to the support frame. By changing the distance between the nozzle 400 and the support frame, it is ensured that the water mist can uniformly cover the test plate. The pump 600 delivers the solution in the receiving tank 500 to the nozzle 400, while a portion of the water mist sprayed by the nozzle 400 can flow back into the receiving tank 500 for recycling.

[0039] Preferably, the nozzle 400 is a high-pressure fine water mist nozzle 400, which improves the uniformity and fineness of the water mist.

[0040] Preferably, the first bracket 100, the second bracket 200, and the third bracket 300 are all made of stainless steel.

[0041] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
