Chifukwa chiyani Mabedi a Precision Granite Amayikidwa mu Makina Opopera a PCB?

 

Pakupanga ma PCB, kulondola n'kofunika kwambiri. Chimodzi mwa zinthu zofunika kwambiri zomwe zimakhudza kulondola ndi bedi la granite lomwe limagwiritsidwa ntchito mu makina opunthira a PCB. Dongosolo loyimitsira lathes la granite ili limagwira ntchito yofunika kwambiri pakukweza magwiridwe antchito ndi kulondola kwa makina onse.

Granite imadziwika chifukwa cha kukhazikika kwake bwino komanso kulimba kwake, zomwe zimapangitsa kuti ikhale chinthu choyenera kugwiritsidwa ntchito molondola. Mabedi a granite akamangiriridwa mu makina obowola a PCB, amachotsedwa ku kugwedezeka ndi kusokonezeka kwakunja komwe kungakhudze njira yobowola. Dongosolo loyimitsali limalola granite kusunga kusalala kwake komanso kulondola kwa mawonekedwe ake, zomwe ndizofunikira kwambiri kuti mabowo obowola agwirizane bwino ndi kapangidwe ka dera.

Kuphatikiza apo, kuyimitsidwa kwa bedi la granite kumathandiza kuchepetsa zotsatira za kutentha. Pamene kutentha kumasintha panthawi yoponda, zinthuzo zimatha kukula kapena kuchepa, zomwe zimapangitsa kuti pakhale kusakhazikika bwino. Mwa kuyimitsidwa kwa bedi la granite, opanga amatha kuchepetsa kutentha kumeneku, kuonetsetsa kuti bedilo limakhala lokhazikika komanso kusunga kulondola kwa kuponda.

Ubwino wina waukulu wa bedi la granite lopachikidwa ndi kuthekera kwake kuyamwa kugwedezeka. Pa ntchito yopondaponda, makinawo amakumana ndi mphamvu zosiyanasiyana zomwe zingayambitse kugwedezeka. Bedi la granite lopachikidwa limagwira ntchito ngati njira yonyowetsa madzi, kunyamula kugundana kumeneku ndikuletsa kuti kusapitirire ku zigawo za makinawo. Izi sizimangowonjezera nthawi yogwira ntchito ya zidazo, komanso zimakweza ubwino wa ma PCB opachikidwapo.

Mwachidule, kuyimitsidwa kwa mabedi a granite olondola mu makina obowola a PCB ndi chinthu chofunikira kwambiri pakupanga kuti chiwongolere kulondola, kukhazikika, komanso kulimba. Mwa kupatula granite ku kugwedezeka ndi kusinthasintha kwa kutentha, opanga amatha kukwaniritsa kulondola kwakukulu pakupanga ma PCB, pamapeto pake kukonza magwiridwe antchito a zida zamagetsi. Pamene kufunikira kwa ma PCB apamwamba kukupitilira kukula, kufunika kwa njira yatsopano yopangira sikunganyalanyazidwe.
