Crystal oscillator inowanzo shandiswa zvewachi maseketi, iro rinonyanya kuita kupa mareferenzi frequency kumifananidzo yemakadhi, makadhi enetiweki, mamaboard uye zvimwe zvikamu zvezvinhu, zvinonyanya kushandiswa mumidziyo yeruzivo, zviteshi zvefoni, smart wear, Internet yezvinhu uye mimwe minda. Iko kushanda kwakajairika kwemaseketi emagetsi kunoenderana neyakajairika, yakagadzikana "wachi chiratidzo", pasi peyakajairika mashandiro ezvinhu, iko kunyatso kurongeka kweyakajairika kristaro frequency inogona kusvika makumi mashanu pamiriyoni.
Chinhu chikuru chinoshanda chequartz kristaro, ine hexagonal conical crystal ine kemikari yakagadzirwa nesilicon dioxide (SiO2).
Quartz ndiyo yakasvibirira yemasonator nekuda kweayo piezoelectric mhedzisiro yezvakanaka (mehendi simba → magetsi), inverse (magetsi → mehendi simba). Kana kumanikidzwa kuchishandiswa pamwe chete nemiseve kana michina yematehwe ematehwe equartz kuti ashandise mafafura, iwo mairi maviri akataridzika kune aya matemo anogadzira magetsi, chiitiko chinozivikanwa seyakajeka piezoelectric mhedzisiro. Kana munda wemagetsi ukaiswa panzvimbo mbiri dzekiristaro yekristaro, wafer inotambanudza kana kumanikidza yakanangana neiyo shaft uye meiki axis, chiitiko chinozivikanwa seyemanikidziro ekugadzirisa. Zvichienderana nehunhu uhwu, kana iyo quartz kristaro ikaiswa mune imwe nzvimbo yemagetsi inoshanduka, iro vhoriyamu rekristaro rinomanikidzwa nguva nenguva kana kutambanudzwa, richiumba iko kwekudengenyeka kwekristaro. Kana kuwanda kwenzvimbo yekuchinjanisa kwakaenzana neyakajairika maonesheni resonance yenguva yewafer, mextial vibration amplitude yewafer ndiyo hombe, zvichikonzera ruzha.
Mukugadzirwa, mana maitirwo esiringi yakanamirwa pamoto, Tuning, kubatana uye kuyedzwa kunowedzeredzwa mune yekutsiva mamiriro sezasi.
Sirivha yakadhinda muchina
Mukuita kwekugadzira quartz yekristaro yezvinhu, maviri-mativi sirivheri yakanamirwa panodiwa nechekare substrate kuti iumbe mairi-mativi electrode. Kwemakore mashoma apfuura, yakakwira vhoriyamu nemashini esirivheri inogadzirwa nemapasuru ekuparadzira. Nekuda kwehunhu uye simba rekushandisa zvinodiwa, turbomolecular pombi inoshandiswa zvishoma nezvishoma kutsiva pombi dzekuparadzira muindasitiri.
Tuning muchina
Ion etching nzira inogamuchirwa kugadzirisa kukora kwecheka pamusoro electrode, kuitira kuti kristaro resonator frequency isvike kune yakatarwa oscillation frequency. Iyo midziyo yakashongedzwa nekaviri yekufambisa chikepe inowanikwa ye1280 yekristaro oscillation zvinhu, zvekushanda kweye-chaiyo-nguva yekutarisa yekristaro oscillation frequency, inogona kubata makumi matanhatu neshanu yekristaro vibration zvinhu panguva imwe chete. Iyo yekutsiva kamuri yemuchina-wekugadzirisa mushini yakakamurwa mukamuri yekugadzirira uye yakanaka-yekugadzirisa kamuri. Kana iyo michina ikavhurwa, iyo yekuvharisa dhigirii yekugadzirira kamuri ichadzikiswa kubva mudenga kumanikidza kuenda kune gumi nePa, iyo yekutsvaira degree yeakanaka-kugadzirisa mukamuri inozopedzisira yaderedzwa kusvika 10-3 kusvika 10-4 Pa. Kazhinji, Pamu mamorekuru anoshandiswa kugadzira iyo yakakwira vacuum mune yakanaka-Tuning kamuri.
Welding muchina
Maitiro ekusimbisa ndeyekuvhara chifukidziro chepamusoro nechigadziko kuti uone kuti chiyero chekukwegura kwechigadzirwa chinosangana nezvinodiwa. Iko kusingasviki kristaro inogona kuzadzwa zvakananga neitrogen gasi kuti isimbiswe, nepo inoshanda kristal inoda kuwedzerwa vibration chip isati yaiswa chisimbiso. Mune iyo yekuvhara annealing maitiro chikamu chemushini wekuisa chisimbiso, yakakwira vacuum inowanikwa nekushandisa mamorekuru pombi.
Mumakore achangopfuura, nekukurumidza kuvandudzwa kwenzvimbo dzekudzika dzakadai se5G, zvemagetsi zvemagetsi uye zviteshi zvefoni, indasitiri yekristaro yakaunza mikana mitsva. Sevhoriyamu indasitiri mhinduro nyanzvi, KYKY ine hupfumi hwechiitiko mumunda wekristaro oscillator, yakapa yakazara yakazara vhoriyamu yezvigadzirwa zvemuchina uye zvakagadziriswa mhinduro. Mune ramangwana, KYKY ichaenderera ichichera zvakadzika muzvikamu zveindasitiri, inonamira kupa vatengi zvigadzirwa zvemhando yepamusoro nemasevhisi.
