Zinthu za granite zatchuka kwambiri pakupanga ndi kupanga makina obowola ndi mphero a PCB.Izi ndichifukwa choti amatha kupirira kutentha kwakukulu komwe kumapangidwa panthawi yopanga makina popanda kutaya kukhulupirika kwawo.Kugwiritsa ntchito zinthu za granite pamakina obowola ndi mphero a PCB kumawonjezera kulondola, kulondola komanso kuthamanga kwa njira zomwe zimapangitsa kuti pakhale zinthu zapamwamba kwambiri.
Kusiyanasiyana kwa kutentha kwa zinthu za granite zomwe zimagwiritsidwa ntchito pobowola PCB ndi makina amphero zimadalira zinthu zingapo.Zinthu izi zikuphatikizapo mtundu wa granite womwe umagwiritsidwa ntchito, makulidwe a chinthu cha granite, kuthamanga kapena mphero, ndi kuya ndi kukula kwa dzenje lomwe likupangidwa.
Kawirikawiri, granite imakhala ndi coefficient yotsika yowonjezera kutentha, zomwe zikutanthauza kuti idzakana kusinthika ndi kuwonongeka chifukwa cha kutentha kwakukulu.Kuonjezera apo, granite imakhala ndi mphamvu yotentha kwambiri, yomwe imalola kuti itenge kutentha ndi kusunga kutentha kosasinthasintha.Izi zimapangitsa kukhala mfundo yabwino ntchito PCB pobowola ndi makina mphero, kumene kutentha kwambiri kwaiye pa ndondomeko Machining.
Zinthu zambiri za granite zomwe zimagwiritsidwa ntchito pobowola PCB ndi makina ophera zimakhala ndi kutentha kwapakati pa 20 ℃ mpaka 80 ℃.Komabe, mitundu iyi imatha kusiyanasiyana malinga ndi mtundu wa granite womwe umagwiritsidwa ntchito.Mwachitsanzo, granite yakuda, yomwe imakhala ndi mphamvu yotentha kwambiri, imatha kupirira kutentha kwambiri poyerekeza ndi mithunzi yopepuka ya granite.
Kuphatikiza pa kusiyanasiyana kwa kutentha, makulidwe a chinthu cha granite ndichinthu chofunikiranso kuganizira.Zinthu zazikuluzikulu za granite zimatha kuyamwa kutentha ndikusunga kutentha kokhazikika panthawi yopanga makina.Izi zimatsimikizira kuti kulondola ndi kulondola kwa makina obowola ndi mphero a PCB kumasungidwa ngakhale atagwiritsidwa ntchito nthawi yayitali.
Liwiro la kubowola kapena mphero ndilofunikanso kuganizira pogwiritsa ntchito zinthu za granite mu PCB pobowola ndi makina ophera.Kuthamanga kwambiri pobowola kapena mphero kumapangitsa kutentha kwambiri, komwe kungayambitse kuwonongeka kwa chinthu cha granite.Chifukwa chake, ndikofunikira kuwongolera liwiro la makina kuti muwonetsetse kuti kusiyanasiyana kwa kutentha kwa chinthu cha granite kumasungidwa.
Pomaliza, kugwiritsa ntchito zinthu za granite kwasintha kwambiri pobowola ndi mphero ya PCB.Zimakhala zolimba ndipo zimatha kupirira kutentha kwambiri popanda kuwonongeka.Kusiyanasiyana kwa kutentha kwa zinthu za granite zomwe zimagwiritsidwa ntchito pobowola PCB ndi makina amphero zili pakati pa 20 ℃ mpaka 80 ℃, kutengera makulidwe ndi mtundu wa granite womwe umagwiritsidwa ntchito.Ndichidziwitsochi, mainjiniya ndi akatswiri amatha kusankha chinthu choyenera cha granite pamakina awo obowola ndi mphero a PCB kuti akwaniritse bwino ntchito yawo ndikukwaniritsa zomaliza zapamwamba.
