Sei PCB yekuchera michina ichifarira ZHHIMG® mabhesi egranite?

Mumunda wePCB kudhirowa chaiko, ZHHIMG® granite base yave iyo inosarudzika kune imwe nheyo yesimbi nekuda kwezvayo zvina zvakakosha:
1. Chimiro chakagadzikana: Kunyanya kupikisa kune deformation
Granite nhema ine density ye3100kg/m³ inosarudzwa. Iyo yemukati yemaminerari makristasi ane dense uye echisikigo mukati kushushikana kuri pedyo ne zero. Kuenzaniswa nedambudziko rekutsvedza kwelatisi remafuremu esimbi pasi pemitoro yenguva refu, mafuremu egranite anogona kudzvanya pamusoro pe90% ye deformation, kuve nechokwadi chekuti mudziyo wekuchera unochengetedza kurongeka kwe ± 1μm kwenguva yakareba.
2. Yakakwira vibration absorption kunyatsoita: Kudhira chaiko kunovandudzwa ne3 nguva.
Iko mukati memaminerari friction yegranite inoumba daping yakasikwa, iyo inogona kutora 90% yesimba rekudengenyeka panguva yekuchera (mabhesi esimbi anogona kungotora 30%). Chiyero chaicho chemugadziri wePCB chinoratidza kuti mushure mekuisa chigadziko chegranite, kushata kwe0.1mm micro-gole madziro kwakadonha kubva kuRa1.6μm kuenda kuRa0.5μm, uye hupenyu hwesevhisi hwechibhorani hwakawedzerwa kaviri.
Tatu. Kugadzikana kwekushisa kwakasimba: Pesvedzero yekusiyana kwekushisa inoderedzwa
Iyo coefficient yekuwedzera kwekupisa ndeye 5.5 × 10⁻⁶/℃ (11.5 × 10⁻⁶/℃ yesimbi). Kana iyo inoenderera yekushanda tembiricha yemidziyo inokwira ne10 ℃, iyo yekupisa deformation yegireni gasi isingasviki 5μm, nepo iyo yesimbi base inogona kusvika 12μm, zvinobudirira kudzivirira gomba chinzvimbo chinokonzerwa nekuwedzera kwekupisa uye kuputika.
Iv. Kugadzirisa Kurongeka: Kunovimbiswa ne nanometer-level zviyero
Iyo inogadziriswa neshanu-axis CNC yekukuya muchina, ine flatness inodzorwa mukati me ± 0.5μm/m, uye inotsigira tsika T-slots, maburi ane shinda uye zvimwe zvakaomarara zvimiro. Mhosva inobva kune imwe fekitori yemidziyo yekuchera inoratidza kuti nzvimbo yekuisa gomba kurongeka kweiyo granite muchina base inosvika ± 0.01mm, iri 50% yakakwirira kupfuura iyo yesimbi muchina base, ichideredza zvakanyanya nguva yekumisikidzwa kwemidziyo.

Mutengo uye mabhenefiti ezvakatipoteredza: Kunyangwe mutengo wekutanga wakakwira 15%, hupenyu hwesevhisi hunodarika makore gumi (makore mashanu chete emafuremu esimbi), uye hazvidi gadziriso. Iyo kabhoni inobuda mumigodhi nekugadziriswa kwegranite yakaderera ne40% pane iyo iri musimbi yekunyungudutsa, izvo zvinoenderana nemaitiro ekugadzira girini.
