Maxay qalabka qodista PCB u door bidaan saldhigyada granite ee ZHHIMG®?

Dhinaca qodista saxda ah ee PCB, saldhigga korantada ee ZHHIMG® wuxuu noqday beddelka la door bidayo saldhigga birta iyadoo ay ugu wacan tahay afarta faa'iidooyin ee aasaasiga ah:
1. Qaab dhismeed xasiloon: Iska caabin heersare ah oo ka dhan ah qallafsanaanta
Granite madow leh cufnaanta 3100kg/m³ ayaa la doortay. Kareemada macdanta gudaha waa cufan iyo walbahaarka gudaha ee dabiiciga ah wuxuu ku dhow yahay eber. Marka la barbar dhigo dhibaatada silbashada shafka ah ee looxyada birta ee ka hooseeya culeysyada muddada dheer, muraayadaha granite waxay xakameyn karaan in ka badan 90% qallafsanaanta, iyaga oo hubinaya in aaladda qodista ay ilaaliso saxnaanta meelaynta ± 1μm muddo dheer.
2. Hufnaanta nuugista gariirka sare: Saxnaanta qodista waxaa la hagaajiyay 3 jeer
Khilaafaadka macdanta gudaha ee granite wuxuu sameeyaa qoyaan dabiici ah, kaas oo nuugi kara 90% tamarta gariirka inta lagu jiro habka qodista (saldhigyada birta waxay nuugi karaan 30%). Cabbirka dhabta ah ee soo saaraha PCB-ga ayaa muujinaya in ka dib markii la rakibo saldhigga granite, qallafsanaanta gidaarka 0.1mm ee dalool-yar oo ka soo dhacay Ra1.6μm ilaa Ra0.5μm, iyo nolosha adeegga qashin-qubka ayaa la kordhiyay laba jeer.
Saddex. Deganaanshaha kulaylka xooggan: Saamaynta kala duwanaanshaha heerkulka waa la yareeyaa
Isku-dhafka ballaarinta kulaylka waa 5.5 × 10⁻⁶ / ℃ (11.5 × 10⁻⁶ / ℃ birta). Marka heerkulka hawlgalka joogtada ah ee qalabku kor u kaco by 10 ℃, qallafsanaanta kulaylka saldhigga granite ka yar yahay 5μm, halka in saldhigga birta gaari karo 12μm, wax ku ool ah oo ka fogaanaya booska godka offset ay sababtay ballaarinta kulaylka iyo foosha.
Iv. Xaqiijinta Habaynta: Waxaa lagu dammaanad qaaday heerarka nanometer-ka
Waxaa lagu farsameeyaa mashiinka wax lagu shiidi karo shan dhidib CNC ah, iyadoo flatness gacanta ku ± 0.5μm / m gudahood, oo ay taageertaa T-slots caadadii, godadka dunta iyo dhismayaasha kale ee adag. Kiis ka yimid warshadda qalabka qodista qaarkood ayaa muujinaysa in saxnaanta booska godka rakibaadda ee saldhigga mashiinka granite uu gaaro ± 0.01mm, taas oo 50% ka sarreysa kan saldhigga mashiinka birta, taasoo si weyn u yareyneysa waqtiga qalabka.

Qiimaha iyo faa'iidooyinka deegaanka: Inkasta oo qiimaha bilowga ahi uu ka sarreeyo 15%, nolosha adeeggu waxay ka badan tahay 10 sano (kaliya 5 sano oo loogu talagalay xirmooyinka birta), uma baahna dayactir. Sii daynta kaarboon ee macdanta iyo farsamaynta granite ayaa 40% ka hooseeya kuwa ku jira birta dhalaalaysa, taas oo la socota isbeddelka wax soo saarka cagaaran.
