Description

Technical Field

[0001] This utility model relates to the field of LTCC filter terminal electrode preparation technology, and in particular to a manual terminal silver jig for LTCC multi-pin electrodes. Background Technology

[0002] LTCC filters are radio frequency filters based on low-temperature co-fired ceramic (LTCC) technology. They feature high-frequency performance, miniaturization, and integration, and are widely used in communication equipment. LTCC filters are made by fabricating multilayer green ceramic tapes from ceramic powder, using processes such as laser drilling and conductor printing to form a three-dimensional circuit structure, integrating passive components such as inductors and capacitors. The fabrication of the terminal electrodes of LTCC filters involves conductor paste printing, via filling, and sintering processes.

[0003] During the development and manufacturing phase of LTCC filters, design requirements necessitate variations in product size and terminal electrodes, all of which are multi-pin electrode designs. To measure electrical properties and confirm performance, significant costs must be incurred in manufacturing various fixtures for the development phase, consuming considerable production time. Furthermore, due to equipment limitations, most products in the development phase can only be manufactured by manually brushing the terminal electrodes, resulting in cumbersome production operations, lengthy individual electrode fabrication times, and significant variations in terminal electrode dimensions, potentially causing continuity issues and impacting functional quality.

[0004] Therefore, a manual silver-end fixture for LTCC multi-pin electrodes is needed to overcome the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a manual end-silvering fixture for multi-pin electrodes in LTCC filters, which solves the problems of low efficiency and large size differences in end electrodes when using manual end-silvering during the development and manufacturing stage of LTCC filters.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A manual silver-end silvering fixture for LTCC multi-pin electrodes includes a base plate, an implantation plate with several implantation holes on the top of the base plate, a silver-end silvering plate with silver-end silvering grooves on the implantation plate, and silver-end silvering paste applied to the top of the silver-end silvering plate, which then passes through the silver-end silvering grooves and into the implantation holes of the implantation plate.

[0007] In this design, the end-silver groove restricts the downward flow of the end-silver paste, allowing it to solidify within the implantation hole after passing through the groove. The end-silver groove acts as a mold, enabling rapid end-silvering operations and high work efficiency. Due to the function of the end-silver groove, the size and appearance of the product's end electrodes are consistent. Furthermore, manual end-silvering fixtures can be designed for products of various sizes and with different pin positions, offering advantages such as simple structure, low cost, and wide applicability.

[0008] Furthermore, two limiting and pressing baffles are fixed to the top of the end silver plate, and the two limiting and pressing baffles are fixed to the two sides of the end silver plate respectively.

[0009] Furthermore, it also includes an end-scaling scraper, which is located between two limiting and pressing baffles and is perpendicular to the length direction of the two limiting and pressing baffles.

[0010] In this design, the silver finishing blade moves between two limiting and pressing baffles, ensuring that it covers the entire area of ​​the finishing plate in one pass, reducing the risk of misalignment of the printing position. Simultaneously, the two limiting and pressing baffles also prevent the silver finishing paste from flowing in the wrong direction, thus preventing it from flowing to the sides during the blade's movement.

[0011] Furthermore, four positioning pins are fixed at the four corners of the implantation plate, and the positioning pins penetrate the implantation plate; the base plate and the end plate are fixed at the bottom and top of the positioning pins, respectively.

[0012] Furthermore, four positioning holes are provided at the four corners of the base plate and the four corners of the end silver plate; the top of the positioning pin is fixed in the positioning hole of the end silver plate, and the bottom of the positioning pin is fixed in the positioning hole of the base plate.

[0013] In this design, positioning holes are provided on the base plate and end plate. During assembly, the positioning holes are simply aligned with the positioning pins, making installation simple and quick.

[0014] Furthermore, two positioning holes are provided at both ends of the two limiting and pressing baffles, and the top of the positioning pin passes through the positioning hole of the end silver plate and is fixed in the positioning hole of the limiting and pressing baffle.

[0015] In this solution, the positioning pin design simultaneously positions the end silver plate and the limiting pressing baffle, resulting in high overall precision after assembly and more accurate alignment between the end silver groove and the implantation hole.

[0016] Furthermore, the implantation holes are rectangular in structure, and several implantation holes are arranged in a rectangular array; the end silver grooves are rectangular in structure, and a row of implantation holes corresponds directly below each end silver groove.

[0017] Furthermore, the implant plate and the silver end plate are made of stainless steel.

[0018] The beneficial effects of this utility model are: This utility model provides a manual silvering fixture for LTCC multi-pin electrodes. The implantation plate and silvering plate can be designed to meet various needs based on product size and electrode pin positions. During insertion, the positioning pin engages with the mold positioning hole, thus assembling the four main structures of the LTCC multi-pin electrode manual silvering fixture. The implantation plate and silvering plate are made of stainless steel, which improves the accuracy of implantation and silvering, and allows for easy cleaning after operation. The base plate and limiting pressure baffle are made of metal, providing counterweight to increase stability during manual silvering. The limiting pressure baffle also limits the use of the silvering scraper, reducing the risk of scraping position deviation. The entire LTCC multi-pin electrode manual silvering fixture has a simple structural design, is easy to operate, and can achieve mass production, thus improving product quality.

An end-silver plate 3 is mounted on the implantation plate 2, with end-silver grooves 8. Two limiting and pressing baffles 4 are fixed to the top of the end-silver plate 3, respectively fixed to both sides of the end-silver plate 3. An end-silver scraper 9 is located between the two limiting and pressing baffles 4 and perpendicular to their length direction. End-silver paste 10 is applied to the top of the end-silver plate 3. The end-silver scraper 9 pushes the paste 10 to flow, and the paste 10 passes through the end-silver grooves 8 and ends up in the implantation holes 7 of the implantation plate 2. The end-silver grooves 8 restrict the downward flow of the paste 10, allowing it to solidify inside the implantation holes 7 after passing through the grooves. The end-silver grooves 8 act as a mold, and this design enables rapid end-silvering, resulting in high work efficiency.

[0023] Two positioning holes 5 are provided at both ends of the two limiting and pressing baffles 4. The top of the positioning pin 6 passes through the positioning hole 5 of the end silver plate 3 and is fixed in the positioning hole 5 of the limiting and pressing baffle 4. Through the design of the positioning pin 6, the end silver plate 3 and the limiting and pressing baffle 4 are positioned simultaneously, resulting in high overall precision after assembly, and the end silver groove 8 and the implantation hole 7 are more accurately aligned.

[0024] The implantation hole 7 has a rectangular structure, and several implantation holes 7 are arranged in a rectangular array; the end silver groove 8 has a rectangular structure, and a row of implantation holes 7 is located directly below each end silver groove 8.

[0025] The implant plate 2 and the silver plate 3 are made of stainless steel.

[0026] The working principle of this embodiment is as follows: The implantation holes 7 on the implantation plate 2 are designed to be 4.5mm wide and 5.0mm long for product implantation. After implantation, the positioning pins 6 are positioned and assembled with the positioning holes 5 on the base plate 1. Then, the four positioning holes 5 on the end silver plate 3 are positioned and assembled with the four positioning pins 6 on the implantation plate 2. The end silver grooves 8 on the end silver plate 3 are designed to be 4.5mm wide, and the center of the end silver grooves 8 must be aligned with the center of the implantation holes 7 to achieve the end silver on the product and conform to the end silver design dimensions. There are two limiting and pressing baffles 4. The positioning holes 5 at the ends of the two limiting and pressing baffles 4 are matched with the positioning pins 6 on the implantation plate 2 to achieve the function of pressing the end silver plate 3 and implanting the steel plate, so as to make the end silver flat during the operation.

[0027] After the assembly is completed, place the silver end scraper 9 in the middle of the limiting and pressing baffle 4, and spread the silver end paste 10 on the silver end plate 3. Use the silver end groove 8 to apply the silver paste to the implant plate 2 product to complete the silver end action.
