Embodiment 1
[0011] Use a specially designed capacitor alignment machine to load the chamfered and cleaned capacitors on the special jig for skilled personnel to expose the length of the sealed end, and then send them into the oven, bake them at 85°C for about 20 minutes, and then install them. to the vacuum coating chamber. The vacuum coating chamber is a magnetically controlled field and is located in a purification workshop. The degree of purification of the purification workshop is more than 10,000 grades, and the frequency of the magnetic control field is 1200 ± 200 Hz. Turn on the rough vacuum pump, and when the vacuum reaches 10Pa, turn on the fine pump cryopump until the vacuum reaches 5×10 -3 After Pa, the magnetron sputtering coating system was turned on for electrode-capped sputtering. The alloy target is a nickel-chromium alloy, Ni:Cr=80:20, the sputtering temperature is 50°C, and the sputtering time is set for 15 minutes. The electrode film thickness of the obtained product ...

[0013] Use a specially designed capacitor alignment machine to load the chamfered and cleaned capacitors on the special jig for skilled personnel to expose the length of the sealed end, and then send them into the oven. After baking at 85°C for about 25 minutes, install them. to the vacuum coating chamber. The vacuum coating chamber is a magnetically controlled field and is located in a purification workshop. The degree of purification of the purification workshop is more than 10,000 grades, and the frequency of the magnetic control field is 1200 ± 200 Hz. Turn on the rough vacuum pump, and when the vacuum reaches 10Pa, turn on the fine pump cryopump until the vacuum reaches 5×10 -3 After Pa, the magnetron sputtering coating system was turned on for electrode-capped sputtering. The alloy target is a nickel-chromium alloy, Ni:Cr=75:25, the sputtering temperature is 70°C, and the sputtering time is set to 18 minutes. The resulting product has uniform electrode film thickness, ...

[0015] Use a specially designed capacitor arrangement machine to load the chamfered and cleaned capacitors on the special jig for skilled personnel to expose the length of the sealed end, and then send them into the oven, bake them at 85°C for about 28 minutes, and then install them. to the vacuum coating chamber. The vacuum coating chamber is a magnetically controlled field and is located in a purification workshop. The degree of purification of the purification workshop is more than 10,000 grades, and the frequency of the magnetic control field is 1200 ± 200 Hz. Turn on the rough vacuum pump, and when the vacuum reaches 10Pa, turn on the fine pump cryopump until the vacuum reaches 3×10 -3 After Pa, the magnetron sputtering coating system was turned on for electrode-capped sputtering. The alloy target is a nickel-chromium alloy, Ni:Cr=82:18, the sputtering temperature is 90°C, and the sputtering time is set for 12 minutes. The resulting product has uniform electrode film th...
