[0053] The outer side of the process circular hole is provided with a chamfer to ensure that the metal diaphragm 3 can be processed evenly.

[0054] The overall structure of the first material tray 1 and the second material tray 2 is made of non-metallic materials to avoid interference from metal sensitivity, and high-performance engineering plastics or rubber materials are preferably used, such as PEEK (polyetheretherketone), PI (polyimide), PPS (polyphenylene sulfide) and fluororubber.

[0055] The metal diaphragm 3 is used as a sensor wafer and is made of 1Cr18Ni9Ti. Figure 6 and Figure 7 As shown, the metal diaphragm 3 is cylindrical as a whole, with one end closed and the other end open, and the open section of the metal diaphragm 3 is bent outward to form a blocking end.

[0056] The overall height L of the metal diaphragm 3 is not greater than 5 mm, the outer diameter d1 of the cylindrical portion is 0.5 mm to 1 mm smaller than the aperture of the process circular hole 103, and the outer diameter D of the blocking end is 0.5 mm to 1 mm larger than the aperture of the process circular hole 103, so that the metal diaphragm 3 can pass through the process circular hole 103 and be clamped between the first material tray 1 and the second material tray 2.

[0059] Specifically, the basket frame assembly includes a basket hanging plate 7, a connecting plate 8, a basket support rod 9 and a basket baffle 10;

[0060] One side of the upper end of the connecting plate 8 is vertically fixedly connected to the basket hanging plate 7, and the basket hanging plate 7 is provided with a hanging part connected to an external device, such as a screw, a hook, a clamp and the like.

[0061] At least two basket support rods 9 vertically pass through the lower end of the connecting plate 8, and the two ends of the basket support rods 9 are respectively connected to a basket baffle 10, so that a space for carrying the material tray assembly is formed between the basket support rods 9, the connecting plate 8 and the basket baffle 10, and the material tray assembly can be tilted and placed between the connecting plate 8 and the basket baffle 10.

[0062] Long holes 16 are provided along the longitudinal direction of the connecting plate 8, and reinforcing rods 14 are inserted into the long holes 15.

[0064] The tray fixing block 11 is fan-shaped and can press the upper end of the tray assembly onto the connecting plate 8 to prevent it from turning outward, thereby avoiding problems such as rotation and shaking of the tray assembly during the process.

[0065] The fixed block stop shaft 13 can limit the rotation range of the tray fixed block 11.

[0066] A fastening screw 16 is also provided on the side of the connecting plate 8 for locking the fixing block shaft 12 to prevent it from rotating or loosening.

[0067] The basket frame assembly, the fixing assembly and the tray assembly are all made of high-performance engineering plastics or rubber materials.

High-performance engineering plastics or rubber materials are preferred, such as PEEK (polyetheretherketone), PI (polyimide), PPS (polyphenylene sulfide) and fluororubber.

[0069] In this embodiment, the metal diaphragm 3 is made of 1Cr18Ni9Ti, the outer diameter D of the blocking end is 9.5mm, and the outer diameter d1 of the cylindrical part is 8mm. Multiple metal diaphragms 3 are installed on the first tray 1 manually or by an external automatic device, and the positions of the first tray 1 and the second tray 2 are aligned by the positioning pin 6, and the fixing pin 5 is locked; the fixed tray assembly is placed tangentially on the basket support rod 9, one side is close to the connecting plate 8, and the tray fixing block 11 is rotated so that the tray fixing block 11 completely locks the tray assembly. The entire basket device is connected to an external manipulator, and subsequent wet etching, development, degumming and other processes are carried out through an electronic control system.

[0070] In another embodiment, the tray assembly can be replaced with a standard 6-inch wafer, which is fixed on the basket frame assembly after clamping and installation, and subsequent wet etching, development, degumming and other processes can be performed.

[0071] This embodiment utilizes the metal ductility of the diaphragm workpiece and improves it into a circular diaphragm with a rib for easy positioning. At the same time, a tray assembly is used to initially fix it, and spacing pins and positioning pins are added to ensure the clamping gap and stability. The two tray assemblies can be processed simultaneously to achieve large-scale workpiece processing, which can greatly increase production efficiency and ensure the stability of the finished workpiece. At the same time, the basket assembly is compatible with standard 6-inch wafer fixing, which can achieve more process options and multi-type product production.

[0072] This application solves the problem of process surface obstruction during the wet processing of metal diaphragms to a certain extent, while meeting the requirements of multi-workpiece processing and compatibility, ensuring that the metal diaphragm is firmly placed in place, greatly reducing the difficulty for operators and improving production efficiency.

[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
