Sei michina yekuboora PCB ichida mabhesi egranite eZHHIMG®?

Munyaya yekuchera nePCB nemazvo, ZHHIMG® granite base ndiyo nzira inonyanya kufarirwa panzvimbo pesimbi nekuda kwezvakanaka zvayo zvina:
1. Chimiro chakagadzikana: Kuramba kwakanaka kwazvo kuchinjika
Granite nhema ine density ye3100kg/m³ inosarudzwa. Makristaro emuchicherwa emukati akaomarara uye kushushikana kwemukati kwechisikigo kuri pedyo ne zero. Kana tichienzanisa nedambudziko rekutsvedza kwemafuremu esimbi ari pasi pemitoro yenguva refu, mafuremu egranite anogona kudzvinyirira pamusoro pe90% yekushanduka, zvichiita kuti mudziyo wekuboorera urambe wakarurama we ±1μm kwenguva yakareba.
2. Kushanda zvakanaka kwekunyudzwa kwemvura: Kururama kwekuchera kunovandudzwa ka3
Kukweshana kwezvicherwa zvegranite mukati kunoita kuti damping ive yechisikigo, iyo inogona kutora 90% yesimba rekudengenyeka panguva yekuboorwa (zvigadziko zvesimbi zvinongotora 30%) chete. Kuyerwa chaiko kwemugadziri wePCB kunoratidza kuti mushure mekuisa chigadziko chegranite, kuomarara kwemadziro e0.1mm micro-hole kwakadzikira kubva paRa1.6μm kuenda kuRa0.5μm, uye hupenyu hwebasa re drill bit hwakawedzerwa kaviri.
Tatu. Kugadzikana kwakasimba kwekupisa: Simba remusiyano wekupisa rinoderedzwa
Chiyero chekuwedzera kwekupisa i5.5×10⁻⁶/℃ chete (11.5×10⁻⁶/℃ yesimbi). Kana tembiricha yekushanda kwemidziyo ichiwedzera ne10℃, kushanduka kwekupisa kwechigadziko chegranite kunenge kuri pasi pe5μm, nepo chigadziko chesimbi chichigona kusvika 12μm, zvichidzivirira nzvimbo yegomba kunokonzerwa nekuwedzera kwekupisa uye kudzikira.
Iv. Kunyatsogadzirisa: Inovimbiswa nemazinga emazinga e nanometer
Inogadziriswa nemuchina wekukuya weCNC une mativi mashanu, uye hurefu hwayo hunodzorwa mukati me ±0.5μm/m, uye inotsigira nzvimbo dzeT dzakagadzirwa, maburi ane shinda nezvimwe zvivakwa zvakaoma. Imwe nyaya inobva kufekitori yemichina yekuboorera inoratidza kuti kurongeka kwenzvimbo yegomba rekuisa kwechigadziko chemuchina wegranite kunosvika ±0.01mm, iyo iri pamusoro pe50% pane yechigadziko chemuchina wesimbi, zvichideredza zvakanyanya nguva yekuiswa kwemuchina.

Zvakanakira mutengo nezvakatipoteredza: Kunyangwe mutengo wekutanga wakakwira ne15%, hupenyu hwebasa hunodarika makore gumi (makore mashanu chete emafuremu esimbi), uye hazvidi kugadziriswa. Kuburitswa kwekabhoni mukuchera nekugadzira granite kwakaderera ne40% pane kuri mukugadzirwa kwesimbi, izvo zvinoenderana nemaitiro ekugadzira zvinhu zvakasvibira.
