M'malo otukuka (monga kutentha kwambiri, kutentha kochepa, kutentha kwambiri), ndikugwirira ntchito kwa granite element mu pcb kubowola ndi chingwe cha makina?

Kugwiritsa ntchito granite mu pcb kubowola kwa PCB ndi milinging kwakhala kotchuka chifukwa cha bata pake, kuvala kwamphamvu, komanso kuthekera kugwedezeka. Komabe, opanga ma PCB ambiri adzutsa nkhawa za magwiridwe antchito a granite mu malo ochulukirapo monga kutentha kwakukulu monga kutentha kwakukulu, kutentha kochepa, komanso chinyezi chachikulu.

Mwamwayi, magwiridwe antchito a granite zinthu mu PCB Kubowola ndi makina ocheperako kumakhala kokhazikika ngakhale m'malo otukuka kwambiri. Choyamba komanso choyambirira, granite amalephera kugwiritsa ntchito kutentha komanso kusinthasintha. Izi ndichifukwa choti granite ndi mtundu wa mwala wachilengedwe womwe umapangidwa ndi kuzizira ndi kulimbikitsa kwa magma. Zotsatira zake, zimatha kukhala ndi malo okwera kwambiri osataya chokhwima kapena mawonekedwe ake.

Kuphatikiza apo, Granite sakukula kuti achuluke kapena kuwongolera ndi kusintha kwa kutentha kapena chinyezi. Kuperewera kwakukulitsa kumeneku ndi contraction kumatsimikizira kuti zinthu za Gran mu Makina a PCB ndizokhazikika pakuchita opareshoni, ndipo makina amatulutsa zotsatira zabwino kwambiri.

Kuphatikiza apo, granite amalimbana kwambiri ndi kuchuluka kwake, komwe ndi mwayi wowonjezereka posunga magwiridwe antchito a PCB ndi makina ocheperako okhala ndi chinyezi chambiri. Kutsutsa kwa granite kumachokera ku zinthu zake za Silica, zomwe zimapangitsa kuti malume azitha kukhala acid ndi alkali, onetsetsani kuti siligwirizana mosavuta.

Ubwino wina wogwiritsa ntchito granite mu PCB kubowola ndi ma makina ocheperako ndi kuthekera kwake kugwedezeka. Izi zimathandizira kuonetsetsa kuti makinawo ndi okhazikika pakuchitapo kanthu ndipo kuti kubowola pang'ono kapena mipata sikukumba kwambiri mu bolodi.

Ponseponse, kugwiritsa ntchito zinthu za Granite ku PCB kubowoleza ndi milling kumalimbikitsa kwambiri. Ndi kukhazikika kwake kwakukulu, kuvala kwambiri kukana, komanso kuthekera kwa kugwedezeka kwa kugwedezeka, granite ndi chinthu chabwino kwambiri pakuwonetsetsa kuti pakupanga ma boloni a madera osindikizidwa.

Pomaliza, opanga PCB sayenera kuda nkhawa za magwiridwe antchito a granite m'malo otukuka. Aminite amatha kukana kutentha, chinyezi, ndi kututa zimapangitsa kukhala wokhazikika komanso wodalirika. Zotsatira zake, kugwiritsa ntchito makina okumba ma pcb ndi opanga kumalimbikitsa kwambiri, ndipo opanga amatha kupumula mosavuta kuti magwiridwe awo azikhala okhazikika komanso odalirika.
