Description

Technical Field

[0001] This utility model relates to the field of experimental technology for preparing stripping fluid, and in particular to a placement device for testing stripping fluid. Background Technology

[0002] During the development of the stripping solution, to verify its stripping effect on photoresist under different formulations, tests were conducted by immersing a substrate coated with photoresist into a beaker containing the stripping solution and performing the stripping operation using a water bath. After heating for a period of time, the substrate was removed, and the stripping effect was observed. This method of testing has the following problems: First, it is inconvenient to place and remove the substrate, which is usually done by tweezers. Removing the substrate can easily damage the photoresist layer, potentially leading to misjudgments of the stripping effect. Utility Model Content

[0003] This invention provides a placement device for testing peeling fluid, which overcomes the shortcomings of the prior art and solves the problem of inconvenient placement and removal of the substrate for testing peeling effect, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A placement device for testing stripping fluid includes a glass jar, the upper end of which is covered with a lid. The lid has a vent hole, which facilitates the absorption and treatment of volatile substances and avoids pollution of the test environment.

[0006] The cover has a pair of concave heads, with insert plates inserted into the lower ends of the vertical sections of the concave heads. Each pair of insert plates on the same side has a lower extension plate formed on its inner side. A vertical groove is formed on the lower extension plate, and an inner protrusion plate is mounted to the lower end of the lower extension plate via screws. A connecting shaft is located on the inner end of the inner protrusion plate, and a pair of rotating protrusion plates are rotatably mounted on the connecting shaft. A lower strip is located at the upper end of the rotating protrusion plate, and an elongated hole is formed on the lower strip. A pair of lower extension screws are threaded through both ends of the elongated hole, and an upper nut is threaded onto the lower extension screw. The upper end of the upper nut acts on the lower wall of the lower strip. A fixing block is welded to the upper end of the lower extension screw, and a placement groove is formed on the upper and inner ends of the fixing block. The placement groove limits the lower end of the substrate, facilitating the insertion and removal of the substrate. The lower extension plate is rotatably mounted on the lower strip to facilitate substrate placement.

[0007] Furthermore, the lower wall of the lid is provided with an inner insert ring, which passes through the glass jar body. The inner insert ring improves the sealing effect after the lid is closed.

[0008] Further, the upper ends of the lower batten are provided with upper convex plates extending upward, the outer wall of the upper convex plate is fixed with a compression spring, the outer end of the compression spring acts on the inner wall of the lower extension plate, the elastic force generated by the compression spring facilitates the outward rotation of the lower extension plate, and when the lower extension plate is in the vertical state, the stability of the connection between the lower extension plate and the concave head is ensured due to the pressure generated by the compression spring.

[0009] Further, in order to lock the vertical state of the lower extension plate and limit the upper end of the base plate, a concave pressing plate is movably arranged between the lower extension plates, the two ends of the concave pressing plate are provided with pull rods, the inner end of the pull rod is provided with an end cap, the inner end of the pull rod is sleeved with a spring, the spring is located on the inner side of the horizontal section of the concave pressing plate, the pull rod is arranged in the vertical slot, the outer end of the pull rod is provided with an outer pull block, the outer pull block is located on the outer side of the lower extension plate, the two ends of the outer pull block are fixed with a hinge screw through threads, a concave top piece is rotatably arranged on the hinge screw, the inner end of the concave top piece abuts against the outer wall of the lower extension plate, and the outer end of the concave top piece is welded with a holding handle.

[0010] Further, in order to facilitate the rotation of the concave top piece, the inner end of the concave top piece is in an arc structure.

[0011] The above technical scheme has the following advantages:

[0012] The base plate can be fixed in a vertical state during the test of the stripping effect of the stripping liquid, so that the stripping operation is facilitated, and the base plate is connected to the cover body, so that the placing and taking out operations of the base plate are facilitated.

The lower batten 34 is provided with a long hole 35, and a pair of downward screws are arranged at both ends of the long hole 35. The downward screws are threadedly connected with an upper nut 36, and the upper end of the upper nut 36 acts on the lower wall of the lower batten 34. The upper end of the downward screw is welded with a fixed block 37, and the upper end and inner side end of the fixed block 37 are open-shapedly formed with a placement slot.

[0022] In the application of the embodiment, the operator inserts the lower end of the substrate into the placement slot, then rotates the two downward plates 31 upward to make the downward plates 31 vertical, then inserts the insert plate 300 on one side of the upper end of the downward plate 31 into the concave head 3, and then inserts the insert plate 300 on the other side of the downward plate 31 into the concave head 3 after the insert plate 300 on the other side is located behind the concave head 3. After the downward plate 31 and the concave head 3 are connected, the operator immerses the substrate into the stripping liquid pre-filled in the glass jar body 1, and then detects the photoresist stripping effect by water bath heating.

[0023] In some optional embodiments, the operator can adjust the position of the fixed block 37 according to the size of the substrate, and then fix the position of the fixed block 37 by tightening the upper nut 36 after adjustment. After fixing, the substrate can be placed in the placement slot.

[0026] When the substrate is placed in the placing groove and the downward extending plates 31 are rotated to the vertical posture, the operator inserts the pull rods into the vertical grooves 30 of the downward extending plates 31, then moves the recessed pressing plate 39 downward, and makes the lower wall of the recessed pressing plate 39 act on the upper end of the substrate, then rotates the recessed pressing plate 46, when the recessed pressing plate 46 is rotated, the inner side end thereof will act on the outer wall of the downward extending plate 31, and in the process of rotation, the pull rod 41 moves outward, at the same time, the spring 43 is compressed, until the recessed pressing plate 46 is in the horizontal state, at this time, not only the vertical posture of the downward extending plate 31 can be ensured, but also the substrate can be fixed.
