Yintoni i-electromagnetic shielding performance yamacandelo egranite kwi-PCB yokomba kunye nomatshini wokungqusha, kwaye ngaba iyanceda ukunciphisa ukuphazamiseka kombane?

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 e-granite anokunciphisa kakhulu i-EMI kunye nemiphumo yayo 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 izakhi ze-granite zibe lolona khetho lufanelekileyo kwiindawo ezisebenzayo ze-PCB zokomba kunye noomatshini bokugaya. Abavelisi ababandakanya amacandelo e-granite koomatshini babo banokuqinisekisa ukuba abathengi babo bafumana oomatshini abazinzileyo nabathembekileyo abasebenza ngokufanelekileyo.
