I-PCB yokomba kunye noomatshini bokungqusha basetyenziswa kakhulu kushishino lwemveliso yombane.Zenzelwe ukubhola kunye neebhodi zesekethe eziprintiweyo (PCBs) ngokuchaneka okuphezulu kunye nesantya.Nangona kunjalo, aba matshini banokuvelisa ukuphazamiseka kwe-electromagnetic (EMI) ngexesha lokusebenza kwabo, okunokuchaphazela ukusebenza kwezixhobo zombane ezikufutshane.Ukunciphisa lo mba, abavelisi abaninzi babandakanya izinto zegranite kwi-PCB yabo yokomba kunye noomatshini bokusila.
Igranite yinto eyenzeka ngokwemvelo, enoxinano oluphezulu eneempawu ezibalaseleyo zokukhusela i-electromagnetic.Ihlala isetyenziselwa ukwakhiwa kweenkqubo eziphezulu ze-audiophile speaker kunye noomatshini be-MRI.Iipropati zegranite ziyenza ibe ngumgqatswa ofanelekileyo wokusetyenziswa kulwakhiwo lwePCB yokomba kunye noomatshini bokusila.Xa zidityanisiwe kwaba matshini, amacandelo egranite anokunciphisa kakhulu i-EMI kunye neziphumo zayo kwizixhobo zombane ezikufutshane.
I-EMI yenzeka xa amasimi ombane eveliswa zizixhobo zombane.Ezi nkalo zinokubangela ukuphazamiseka kwezinye izixhobo zombane, ezikhokelela kukungasebenzi kakuhle okanye ukusilela.Ngokuntsonkotha okwandayo kweenkqubo zombane, imfuno yokhuselo lwe-EMI esebenzayo iya ibaluleke kakhulu.Ukusetyenziswa kwezixhobo zegranite kwi-PCB yokomba kunye noomatshini bokugaya kunokubonelela ngesi sikhuselo.
I-Granite yi-insulator egqwesileyo kwaye ayiwubambi umbane.Xa i-EMI iveliswa kwi-PCB yokomba kunye nomatshini wokusila, inokufunxwa ngamacandelo egranite.Amandla afunxayo ke achithwa ngendlela yobushushu, ukunciphisa amanqanaba e-EMI ngokubanzi.Olu phawu lubalulekile kwinkqubo yokwenziwa kwee-PCBs kuba amanqanaba aphezulu e-EMI anokubangela iibhodi ezineziphene.Ukusetyenziswa kwamacandelo egranite kwi-PCB yokomba kunye noomatshini bokungqusha kunokunciphisa umngcipheko weebhodi ezineziphene ngenxa ye-EMI.
Ngaphezu koko, i-granite yomelele ngokumangalisayo kwaye iyamelana nokunxiba kunye nokukrazula.Ine-coefficient ephantsi yokwandiswa kwe-thermal, oku kuthetha ukuba inokumelana namaqondo okushisa agqithisileyo ngaphandle kokuphazamiseka okanye ukuqhekeka.Ezi mpawu zenza amacandelo egranite alungele ukusetyenziswa kwiindawo zokusebenza ezirhabaxa zePCB zokomba kunye noomatshini bokusila.Ukuqina kwamacandelo e-granite kuqinisekisa ukuba umatshini uya kusebenza ngokufanelekileyo iminyaka, ukunciphisa iindleko zokugcina kunye nexesha lokunciphisa.
Ukuqukumbela, ukusetyenziswa kwamacandelo e-granite kwi-PCB yokomba kunye noomatshini bokugaya yindlela esebenzayo yokunciphisa amanqanaba e-EMI kunye nomngcipheko weebhodi ezineziphene.Iimpawu zokukhusela i-granite zenza ukuba ibe yinto efanelekileyo yokusetyenziswa ekwakhiweni kwaba matshini.Ukuqina kunye nokuxhathisa ukunxiba kunye nokukrazula kwenza ukuba iinxalenye zegranite zibe lolona khetho lufanelekileyo kwiindawo ezisebenza nzima zePCB yokomba kunye noomatshini bokusila.Abavelisi ababandakanya amacandelo e-granite koomatshini babo banokuqinisekisa ukuba abathengi babo bafumana oomatshini abazinzileyo nabathembekileyo abasebenza ngokufanelekileyo.
