M'malo ovuta kwambiri (monga kutentha kwambiri, kutentha pang'ono, chinyezi chambiri), kodi magwiridwe antchito a granite mu PCB pobowola ndi makina amphero ndi okhazikika?

Kugwiritsa ntchito granite pamakina obowola ndi mphero a PCB kwatchuka kwambiri chifukwa cha kukhazikika kwake kwapamwamba, kukana kuvala kwambiri, komanso kuthekera kochepetsera kugwedezeka.Komabe, opanga ma PCB ambiri adzutsa nkhawa za momwe ma granite amagwirira ntchito m'malo ovuta kwambiri monga kutentha kwambiri, kutentha pang'ono, ndi chinyezi chambiri.

Mwamwayi, magwiridwe antchito a granite pamakina obowola ndi mphero a PCB ndi okhazikika ngakhale m'malo ovuta kwambiri.Choyamba, granite imagonjetsedwa kwambiri ndi kusintha kwa kutentha ndi kusinthasintha.Izi zili choncho chifukwa granite ndi mtundu wa mwala wachilengedwe womwe umapangidwa ndi kuzizira ndi kulimba kwa magma osungunuka.Chifukwa chake, imatha kupita kumadera otentha kwambiri osataya kukhazikika kwake kapena mawonekedwe ake.

Kuphatikiza apo, granite simakonda kukula kapena kutsika ndi kusintha kwa kutentha kapena chinyezi.Kuperewera kwa kukulitsa ndi kutsika kumeneku kumatsimikizira kuti zinthu za granite mu makina obowola ndi mphero a PCB zimakhalabe zokhazikika panthawi yogwira ntchito, komanso kuti makinawo amatulutsa zotsatira zolondola, zapamwamba kwambiri.

Kuonjezera apo, granite imagonjetsedwa kwambiri ndi dzimbiri, yomwe ndi mwayi wowonjezera pokhudzana ndi kusunga magwiridwe antchito a PCB pobowola ndi mphero m'malo a chinyezi chambiri.Kukaniza kwa granite kumachokera ku silika yake, yomwe imapangitsa kuti mwalawo ukhale wosagwirizana ndi ma acid ndi alkalis, motero kuonetsetsa kuti sichiwononga mosavuta.

Ubwino wina wogwiritsa ntchito granite pamakina obowola ndi mphero a PCB ndikutha kutsitsa kugwedezeka.Izi zimathandiza kuti makinawo azikhala okhazikika panthawi yogwira ntchito komanso kuti chobowola kapena chodula mphero sichimakumba mozama mu bolodi.

Ponseponse, kugwiritsa ntchito zinthu za granite pamakina obowola ndi mphero a PCB ndikulimbikitsidwa kwambiri.Ndi kukhazikika kwake kwapamwamba, kukana kuvala kwambiri, komanso kutha kutsitsa kugwedezeka, granite ndiye chinthu chabwino kwambiri chowonetsetsa kulondola komanso kulondola komwe kumafunikira panthawi yopanga ma board osindikizidwa.

Pomaliza, opanga PCB sayenera kuda nkhawa ndi magwiridwe antchito a granite m'malo ovuta kwambiri.Kutha kwa granite kukana kusintha kwa kutentha, chinyezi, ndi dzimbiri kumapangitsa kuti ikhale yokhazikika komanso yodalirika.Chotsatira chake, kugwiritsa ntchito granite mu PCB pobowola ndi mphero makina akulimbikitsidwa kwambiri, ndipo opanga akhoza kupuma mosavuta podziwa kuti ntchito makina awo adzakhala okhazikika ndi odalirika.
