Chifukwa chiyani Mabedi a Precision Granite Amayimitsidwa mu Makina Okhomerera a PCB?

 

Pakupanga makina osindikizira (PCB), kulondola ndikofunikira. Chimodzi mwazinthu zazikulu zomwe zimakhudza kulondola ndi bedi la granite lomwe limagwiritsidwa ntchito pamakina akukhomera a PCB. Dongosolo loyimitsidwa lazingwe za granitezi limagwira ntchito yofunika kwambiri pakuwongolera magwiridwe antchito komanso kulondola kwa makina.

Granite imadziwika chifukwa cha kukhazikika kwake komanso kusasunthika, zomwe zimapangitsa kuti ikhale chinthu choyenera kugwiritsa ntchito molondola. Pamene mabedi a granite atayimitsidwa mu makina okhomerera a PCB, amasiyanitsidwa ndi kugwedezeka ndi kusokonezeka kwakunja komwe kungakhudze nkhonya. Dongosolo loyimitsidwali limalola kuti granite ikhalebe yosalala komanso yolondola, zomwe ndizofunikira kwambiri kuti zibowo za nkhonya zigwirizane bwino ndi kapangidwe ka dera.

Kuonjezera apo, kuyimitsidwa kwa bedi la granite kumathandiza kuchepetsa zotsatira za kuwonjezereka kwa kutentha. Pamene kutentha kumasinthasintha panthawi yosindikizira, zinthuzo zimatha kukulirakulira kapena kuphatikizika, zomwe zimapangitsa kuti pasakhale kusamvana. Poyimitsa bedi la granite, opanga amatha kuchepetsa kutenthedwa kumeneku, kuonetsetsa kuti bedi limakhala lokhazikika komanso kusunga masitampu olondola.

Ubwino winanso wofunikira wa bedi loyimitsidwa la granite ndikutha kutengera mantha. Pa ntchito yosindikiza, makinawo amawonekera ku mphamvu zosiyanasiyana zomwe zingayambitse kugwedezeka. Bedi la granite loyimitsidwa limagwira ntchito ngati njira yonyowetsa, kutengera izi ndikuletsa kufalikira kuzinthu zamakina. Izi sikuti zimangowonjezera moyo wautumiki wa zida, komanso zimakulitsa mtundu wa ma PCB osindikizidwa.

Mwachidule, kuyimitsidwa kwa mabedi olondola a granite m'makina okhomerera a PCB ndichinthu chofunikira kwambiri chopangira kuwongolera kulondola, kukhazikika komanso kukhazikika. Polekanitsa granite kuchokera ku kugwedezeka ndi kusinthasintha kwa kutentha, opanga amatha kukwaniritsa zolondola kwambiri pakupanga kwa PCB, pamapeto pake kuwongolera magwiridwe antchito a zida zamagetsi. Pomwe kufunikira kwa ma PCB apamwamba kwambiri kukupitilira kukula, kufunikira kwa njira yopangira izi sikunganenedwe.
