Umklamo we-PCB ojwayelekile awudluli ku-10a, ikakhulukazi e-elekthronikhi yasendlini nalowo wabathengi, imvamisa ukusebenza okuqhubekayo kokusebenza kwe-PCB akudluli ku-2A.

Kodwa-ke, eminye imikhiqizo yenzelwe i-Worwer Wiring, kanye namanje aqhubekayo angafinyelela cishe ngo-80a. Uma ubheka amanje wamanje futhi ushiye umugqa wohlelo lonke, okuqhubekayo kwamanje kwentambo yamandla kufanele akwazi ukubekezelela ngaphezu kwe-100a.

Ngemuva kwalokho umbuzo uwukuthi, Hlobo luni lwe-PCB olungamelana ne-100A yamanje?

Indlela 1: Isakhiwo ku-PCB

Ukuthola amandla okudlula okuphezulu kwe-PCB, okokuqala siqala ngesakhiwo se-PCB. Thatha i-PCB ebheke kabili njengesibonelo. Lolu hlobo lwebhodi yesifunda luvame ukuba nesakhiwo esinezingqimba ezintathu: isikhumba sethusi, ipuleti, nesikhumba sethusi. Isikhumba se-Copper yindlela lapho okwenziwa khona namanje kanye nesiginali ku-PCB Pass.

Ngokolwazi lwe-physics yesikole esiphakathi, singazi ukuthi ukumelana kwento kuhlobene nento ebonakalayo, indawo yesigaba sesigaba nobude. Kusukela kugijime lethu lamanje esikhunjeni sethusi, ukumelana kuyalungiswa. Indawo ephambanisa nesigaba ingabhekwa njengobukhulu besikhumba sethusi, okuwubukhulu bethusi ezikhethweni zokucubungula i-PCB.

Imvamisa ubukhulu bethusi buvezwa ku-OZ, ukushuba kwethusi ka-1 oz kungu-35 um, 2 oz uneminyaka engama-70, njalonjalo. Lapho-ke ingaphethwa kalula ukuthi lapho ikhona manje idluliswa kwi-PCB, i-wiring kufanele ibe mfushane futhi ibe mfushane, futhi ubukhulu bokuqina kwe-PCB, okungcono.

Empeleni, ebunjiniyela, asikho isilinganiso esiqinile sobude be-wiring. Imvamisa esetshenziswa ku-Engineering: Ubukhulu be-Copper / Ukushisa okuphezulu / ububanzi be-wire, lezi zinkomba ezintathu ukukala umthamo wokuphatha we-PCB.
