Kodi ma electromagnetic shielding amatha bwanji pazigawo za granite mu makina obowola ndi mphero a PCB, ndipo kodi zimathandizira kuchepetsa kusokoneza kwamagetsi?

Makina obowola a PCB ndi mphero amagwiritsidwa ntchito kwambiri pamakampani opanga zamagetsi.Amapangidwa kuti azibowola ndi mphero matabwa osindikizira dera (PCBs) ndi mwatsatanetsatane mkulu ndi liwiro.Komabe, makinawa amatha kupanga ma electromagnetic interference (EMI) panthawi yogwira ntchito, zomwe zingakhudze magwiridwe antchito amagetsi omwe ali pafupi.Kuti achepetse vutoli, opanga ambiri akuphatikiza zigawo za granite mumakina awo obowola ndi mphero a PCB.

Granite ndi chinthu chongochitika mwachilengedwe, chokhala ndi kachulukidwe kwambiri chomwe chili ndi zida zabwino kwambiri zotchingira ma elekitiroma.Amagwiritsidwa ntchito nthawi zambiri pomanga makina apamwamba kwambiri a audiophile speaker ndi makina a MRI.Makhalidwe a granite amapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pomanga makina obowola ndi mphero a PCB.Zikaphatikizidwa m'makinawa, zigawo za granite zimatha kuchepetsa kwambiri EMI ndi zotsatira zake pazida zamagetsi zapafupi.

EMI imachitika pamene minda yamagetsi imapangidwa ndi zida zamagetsi.Minda imeneyi ingayambitse kusokoneza zipangizo zina zamagetsi, zomwe zimapangitsa kuti zikhale zovuta kapena zolephera.Ndi kuchulukirachulukira kwa makina apakompyuta, kufunikira koteteza kwa EMI kogwira mtima kukukulirakulira.Kugwiritsa ntchito zida za granite pobowola PCB ndi makina amphero kungapereke chitetezo ichi.

Granite ndi insulator yabwino kwambiri ndipo siyendetsa magetsi.EMI ikapangidwa mu makina obowola a PCB ndi mphero, imatha kutengeka ndi zida za granite.Mphamvu yotengedwa imatayidwa ngati kutentha, kuchepetsa milingo yonse ya EMI.Izi ndizofunikira popanga ma PCB chifukwa kuchuluka kwa EMI kumatha kupangitsa kuti ma board asokonekera.Kugwiritsa ntchito zigawo za granite mu PCB kubowola ndi makina mphero kungachepetse chiopsezo cha matabwa opanda pake chifukwa cha EMI.

Komanso, granite ndi yolimba kwambiri komanso yosagwira ntchito komanso kung'ambika.Lili ndi coefficient yotsika yowonjezera kutentha, zomwe zikutanthauza kuti imatha kupirira kutentha kwambiri popanda kugwedezeka kapena kusweka.Zinthuzi zimapangitsa zigawo za granite kukhala zabwino kuti zigwiritsidwe ntchito m'malo ovuta a PCB pobowola ndi makina opangira mphero.Kukhazikika kwa zigawo za granite kumatsimikizira kuti makinawo azigwira ntchito bwino kwa zaka zambiri, kuchepetsa ndalama zosamalira komanso nthawi yopuma.

Pomaliza, kugwiritsa ntchito zida za granite pamakina obowola ndi mphero a PCB ndi njira yabwino yochepetsera milingo ya EMI ndi chiopsezo cha matabwa opanda pake.Kutetezedwa kwa granite kumapangitsa kukhala chinthu choyenera kugwiritsidwa ntchito popanga makinawa.Kukhalitsa komanso kukana kuvala ndi kung'ambika kumapangitsa zigawo za granite kukhala chisankho chabwino kwambiri pazovuta zogwirira ntchito za PCB pobowola ndi makina ophera.Opanga omwe amaphatikiza zida za granite m'makina awo amatha kuonetsetsa kuti makasitomala awo amalandira makina olimba komanso odalirika omwe amagwira ntchito bwino.
