Uyilo oluqhelekileyo lwe-PCB lwangoku aludluli kwi-10A, ngakumbi kwi-elektroniki yasekhaya nakubathengi, ngokuqhelekileyo ukusebenza okuqhubekayo kwi-PCB akudluli kwi-2A.

Nangona kunjalo, ezinye iimveliso zenzelwe i-wiring yamandla, kwaye ikhoyo ngoku eqhubekayo inokufikelela malunga ne-80A.Ukuqwalasela umbane okhawulezayo kunye nokushiya umda wenkqubo yonke, umbane oqhubekayo we-wiring yamandla kufuneka ukwazi ukumelana ne-100A.

Emva koko umbuzo ngulo, luhlobo luni lwePCB olunokumelana ne-100A yangoku?

Indlela yoku-1: Uyilo kwiPCB

Ukuqonda isakhono sangoku se-PCB, siqale siqale ngesakhiwo sePCB.Thatha i-PCB enemigangatho emibini njengomzekelo.Olu hlobo lwebhodi yesekethe ngokuqhelekileyo lunesakhiwo esinemigangatho emithathu: ulusu lobhedu, ipleyiti, kunye nesikhumba sobhedu.Ulusu lobhedu yindlela apho i-current kunye nesignali kwi-PCB idlula.

Ngokolwazi lwefiziksi yesikolo esiphakathi, sinokwazi ukuba ukuchasana kwento kuhambelana nezinto eziphathekayo, indawo enqamlezileyo, kunye nobude.Ekubeni i-current yethu isebenza kwi-copper skin, i-resistivity imisiwe.Ummandla onqamlezileyo unokuthathwa njengobunzima besikhumba sobhedu, obunzima bobhedu kwiinketho zokusetyenzwa kwePCB.

Ngokuqhelekileyo ubukhulu bobhedu bubonakaliswa kwi-OZ, ubukhulu bobhedu be-1 OZ yi-35 um, i-2 OZ yi-70 um, njalo njalo.Emva koko kunokugqitywa ngokulula ukuba xa umsinga omkhulu uza kugqithiswa kwi-PCB, i-wiring kufuneka ibe mfutshane kwaye ibe nkulu, kwaye ubukhulu be-copper ye-PCB, bungcono.

Ngokwenyani, kubunjineli, akukho mgangatho ungqongqo wobude bocingo.Idla ngokusetyenziswa kubunjineli: ubukhulu bobhedu / ukunyuka kweqondo lobushushu / idiameter yocingo, ezi zalathisi zintathu ukulinganisa umthamo wangoku webhodi yePCB.
