Okwangoku, kwishishini lokulungisa imveliso, Ibhodi PCB ibaluleke njengenye yezinto eziphambili ze-elektroniki. Okwangoku, ibhodi ye-PCB ineentlobo ezahlukeneyo, ezinjengebhodi ephezulu yePCB, ibhodi yokufudumeza imicrowave kunye nezinye iintlobo zebhodi eprintiweyo yePCB esele yenze igama elithile kwintengiso yentengiso. Abavelisi bePCB baneendlela ezikhethekileyo zokuqhubekeka zeentlobo ezahlukeneyo zeebhodi zePCB. Kodwa ngokubanzi, imveliso yebhodi ye-PCB kunye nokulungiswa kufuneka kuthathelwe ingqalelo amanqanaba amabini okanye amathathu.

1. Cinga ngokukhethwa kweplate

Isitshixo sebhodi ye-PCB singahlulahlulwa sibe yimveliso yemichiza ekrwada kunye nezinto ezingaphiliyo ezibonakalayo, iindidi ezimbini, into nganye eluhlaza ihlala inezibonelelo zayo ezizodwa. Ke ngoko, uhlobo olucacileyo lweplate luthathela ingqalelo iipropathi zedizeli, iintlobo zefoyile yobhedu, ukutyeba kwesiseko somjelo, kunye neempawu zemveliso kunye nokulungiswa. Phakathi kwabo, ubukhulu bomhlaba wefoyile wobhedu yeyona meko iphambili yokwenzakalisa iimpawu zebhodi eprintiweyo yePCB. Ngokubanzi, ukujiya kwesinyibilikisi, ukulungiselela inkqubo yokudibanisa efanelekileyo kunye nokuphucula ipatheni yokuchaneka okuphezulu kunezibonelelo.

2. Thatha ingqalelo inkqubo yokumisela inkqubo

Imeko-bume yendalo yemveliso yebhodi ye-PCB kunye nomsebenzi wokuqhubekeka kwinqanaba elibaluleke kakhulu, kwaye ulawulo lobushushu obusebenzayo kunye nokufuma komoya zizinto ezibalulekileyo. Ukuba utshintsho lobushushu olusebenzayo lucace gca, kunokubangela ukuba umngxunya ojikelezayo kwipleyiti uqhekeke. Ukuba ukufuma okuhambelana nomoya kukhulu kakhulu, ukuveliswa kwamandla enyukliya kunengozi embi kwiipleyiti ezinesakhono esomeleleyo sokubhabha, ikakhulu kuboniswe kwinqanaba lokusebenza kwele dielectric. Ke ngoko, kuyimfuneko ukugcina imilinganiselo yendalo yokumodareyitha kwimveliso yebhodi ye-PCB kunye nemveliso.

3. Cinga ngokukhethwa kwenkqubo yemveliso

Ukuveliswa kwe-PCB kulula kakhulu ukuhlangabezana nokwenzakala kwezinto ezahlukeneyo, inamba yemveliso kunye nenqubo yokuqhubekeka, itekhnoloji yokulungisa umngxunya, isisombululo sokwaleka komphezulu kunye nezinye iinkqubo zemveliso ziya kukhokelela ekwenzakaleni komgangatho webhodi ye-PCB. Ke ngoko, kuthathelwa ingqalelo imeko yendalo yale nkqubo yokuvelisa, imveliso yebhodi ye-PCB kunye nokulungiswa kuhlanganiswe neempawu zoomatshini bokuvelisa kunye nezixhobo, inokuhlengahlengiswa ngokuhambelana nohlobo lwebhodi ye-PCB kunye neemfuno zemveliso kunye nokulungiswa.

Ukusuka ekhohlo nasekunene, ukhetho lwebhodi yePCB, ukumiselwa kwenkqubo yemveliso kunye nokukhethwa kwenkqubo yemveliso kufuneka kuthathelwe ingqalelo kwimveliso nakwinkqubo yebhodi yePCB. Ukongeza, izinto zokwakha zebhodi ye-PCB kunye nendlela yokuvula yinqanaba ekufuneka likhethwe ngononophelo, elinxulumana ngokusondeleyo nokubengezela kweplate yeemveliso ezigqityiweyo zebhodi yokuprinta yokupakisha yesekethe yamandla.
