Zotsatira za Zigawo za Granite pa Kuwongolera Ubwino wa PCB.

 

Mu dziko lomwe likusintha nthawi zonse popanga zinthu zamagetsi, kuwongolera bwino kwa ma printed circuit board (PCBs) ndikofunikira kwambiri. Chinthu chimodzi chomwe nthawi zambiri chimayiwalika chomwe chimakhudza kwambiri ubwino wa PCB ndikugwiritsa ntchito zigawo za granite popanga zinthu. Granite, yomwe imadziwika kuti ndi yolimba komanso yokhazikika, imagwira ntchito yofunika kwambiri pakuwonetsetsa kuti PCB ikupanga zinthu molondola komanso molondola.

Zigawo za granite, monga matebulo owunikira ndi ma jig, zimapereka malo okhazikika komanso athyathyathya omwe ndi ofunikira kwambiri pakulumikizana ndi kusonkhana kwa ma PCB. Kapangidwe kake ka granite, kuphatikizapo kukana kwake kutentha ndi kugwedezeka, kumathandizira kuti pakhale malo opangira zinthu okhazikika. Kukhazikika kumeneku ndikofunikira kuti pakhale kulekerera kolimba komwe kumafunika pazida zamakono zamagetsi, chifukwa ngakhale kusintha pang'ono kungayambitse mavuto pakugwira ntchito kapena kulephera kwa zinthu.

Kuphatikiza apo, kugwiritsa ntchito granite poyang'anira khalidwe kumawongolera kulondola kwa miyeso yomwe imatengedwa panthawi yowunikira. Zipangizo zoyezera zolondola kwambiri, zikayikidwa pamwamba pa granite, zimachepetsa zolakwika zomwe zimachitika chifukwa cha kusakhazikika kwa pamwamba. Izi zimapangitsa kuti pakhale deta yodalirika kwambiri, zomwe zimathandiza opanga kuzindikira zolakwika kumayambiriro kwa nthawi yopangira ndikugwiritsa ntchito njira zowongolera munthawi yake.

Kuphatikiza apo, zigawo za granite ndizosavuta kuyeretsa ndi kusamalira, zomwe ndizofunikira kwambiri popanga zinthu komwe zinthu zodetsa zingakhudze ubwino wa PCB. Chikhalidwe cha granite chopanda mabowo chimalepheretsa kuyamwa kwa fumbi ndi mankhwala, kuonetsetsa kuti pamwamba pake pamakhalabe pabwino komanso kuti pakhale kupanga kwabwino kwambiri.

Pomaliza, mphamvu ya zigawo za granite pakuwongolera khalidwe la PCB siingapeputsidwe. Mwa kupereka malo okhazikika, olondola komanso oyera opangira ndikuwunika, granite imagwira ntchito yofunika kwambiri pakukweza mtundu wonse wa ma PCB. Pamene kufunikira kwa zinthu zamagetsi zamagetsi zogwira ntchito bwino kukupitilira kukula, kuyika ndalama mu mayankho opangidwa ndi granite ndikofunikira kwa opanga omwe akufuna kusunga mwayi wopikisana ndikuwonetsetsa kuti zinthuzo ndi zodalirika.
