5G filter will have a large-scale development in the next five years. According to relevant data, there will be nearly 20 billion market demand in the next five years. Dielectric filter occupies a quarter of the whole market, up to tens of billions. At present, the production of ceramic dielectric filter is still in the primary stage, and major manufacturers strive to improve the technological process and enhance the production capacity.RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
In 5G era, the traditional metal cavity filter can not achieve the system compatibility problem of high suppression, while the ceramic dielectric cavity can solve these problems. The microwave dielectric ceramic filter is an important solution for 5G in the future.RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
The performance of ceramic dielectric filter is determined by the ceramic powder formula and production process. It is necessary to control the process as much as possible to produce ceramic materials with less impurities, fewer defects and even distribution of grains.RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
The production process of ceramic dielectric filter is as follows:RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
1. Ingredients: set the proportion of various raw materials according to the formula;RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
2. Mixing: in the mixing workshop, weigh the ingredients with a balance, pour them into a designated container and put them into the mixer, and add different proportions of deionized water according to different formulas;RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
3. Drying: send the mixed materials to the drying oven for drying;RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
4. Pre burning: the dried materials are put into the low temperature tunnel furnace for pre burning (the pre burning temperature is controlled at 1100-1200 ℃)RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
5. Spray granulation: after precalcined materials are crushed lightly, polyvinyl alcohol (binder) is added to spray and granulate in full closed spray granulation, so that the material forms very uniform particles.RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
6. Dry pressing: dry pressing the granulated powder with a moldRRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
7. CNC processing: depending on the product structure, add CNC process to products that can not be formed in one time, and press them;RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
8. Discharging and firing: the materials after dry pressing are sintered into porcelain by electric heating at 1600-1700 ℃;RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
9. Double sided grinding: green soft sand and water are used to grind the sintered blank to the exact size of the blank;RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
10. Surface metallization: the surface metallization is carried out by using silver slurry dropping hole, screen printing silver and burning silver after silver dipping;RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
After surface metallization, it can be debugged by CNC according to product performance requirementsRRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
11. Laser electrode: the metallized embryo is processed by laser, and the silver is burned off by laser source;RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
12. Machining electrode: the metallized embryo parts are processed by numerical control drilling machine, and the silver layer of electrode is removed by grinding with drill;RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
13. Cleaning and drying: clean and dry the embryo parts with qualified electrode;RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
14. Assembly: the dried products are SMT welded, reflow welded with solder paste, manually welded and divided into plates;RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
15. FM test: final FM test or laser automatic debugging through network analysis.RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
16. Product identification and shielding: identify and shield qualified products (paste bar code and shielding film)RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
17. Final test: conduct final testRRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
18. Packaging: finally, the barcode scanning and packaging are carried out.RRFMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
