Iinjineli esele zisenza PCB Ubeko lweminyaka lushwankathele ezinye zeendawo eziphambili zenkxalabo, apho iluphu yamandla yindawo ekufanele ukuba iqwalaselwe. Ke, uyenza njani isekethe yaMandla kuyilo lwebhodi yePCB?

Okokuqala, ibhodi yamandla ibaluleke ngakumbi ukumelana nenxalenye yeluphu yamandla, kulwakhiwo kufuneka kuqala lwazi icandelo lamandla eempawu zesekethe, kwisekethe yamandla yahlulwe ikakhulu kwisiphaluka se-DI / DT kunye ne-DV / DT, hamba xa Ubeko lwemigca emibini alufani.

Kuba ixesha leyunithi yesekethe ye-DI / DT likhulu xa utshintsho langoku, eli candelo lesekethe kufuneka libe lincinci ngokusemandleni kumda wokujikeleza wesekethe yonke. Utshintsho lombane wesekethe ye-DV / DT kwixesha leyunithi liya kuba likhulu ngokulula, kulula ukubangela uphazamiseko lwangaphandle, ke isekethe kulusu lobhedu olungasasebenziyo ayinakubanzi kakhulu, ukuze kuhlangatyezwane nothotho lwangoku, ububanzi besikhumba sobhedu buncinci kunokwenzeka, indawo eyahlukileyo yokugquma indawo encinci kangangoko kunokwenzeka.

Okwesibini, indawo eqhuba emgceni kufuneka iqale iqwalasele indawo yeringi yonke yokuqhuba, incinci ngokusemandleni, ukuze uhlale kude nomthombo wokuphazamiseka, kwaye ukufutshane nendawo yokuqhuba.

Iimpawu zesampulu kufuneka zithintele ukuphazamiseka kweminye imiqondiso kangangoko kunokwenzeka. Ukuba kunokwenzeka, imiqondiso yesampulu inokusetyenziswa ngokungafaniyo kwisampulu kwaye inikwe inqwelomoya epheleleyo kumhlaba ohambelana nocingo.
