Ukuqhutshwa kwendiza yamandla kudlala indima ebaluleke kakhulu ekwakhiweni kwe-PCB. Kumklamo ophelele wokwenziwa, ukucutshungulwa kokuphakelwa kwamandla kunganquma inani lempumelelo lama-30% – 50% wephrojekthi. Ngalesi sikhathi, sizokwethula izinto eziyisisekelo okufanele zicatshangelwe ekusetshenzisweni kwendiza yamandla ekwakhiweni kwe-PCB.
1. Uma kwenziwa ukucutshungulwa kwamandla, ukucatshangelwa kokuqala kufanele kube umthamo wayo wokuthwala wamanje, kufaka phakathi izinto ezimbili.
(a) Ukuthi ububanzi bolayini wamandla noma ububanzi beshidi lethusi banele. Ukuze ucabangele ububanzi bolayini wamandla, qala ngokuqonda ubukhulu bensimbi besendlalelo lapho ukucutshungulwa kwesiginali yamandla kutholakala khona. Ngaphansi kwenqubo ejwayelekile, ubukhulu bethusi besendlalelo sangaphandle (ungqimba ophezulu / phansi) we-PCB ngu-1oz (35um), futhi ubukhulu bethusi besendlalelo sangaphakathi buzoba yi-1oz noma i-0.5oz ngokuya ngesimo sangempela. Ngobukhulu be-1oz yethusi, ngaphansi kwezimo ezijwayelekile, i-20MIL ingathwala cishe i-1A yamanje; 0.5oz ukujiya kwethusi. Ngaphansi kwezimo ezijwayelekile, i-40mil ingathwala cishe i-1A yamanje.
(b) Ukuthi usayizi nenombolo yezimbobo kuyahlangabezana yini namandla okugeleza kwamandla wamanje ngesikhathi sokushintsha kwesendlalelo. Okokuqala, qonda ukugeleza komthamo owodwa ngembobo. Ngaphansi kwezimo ezijwayelekile, ukukhuphuka kwezinga lokushisa ngama-degree angama-10, angabhekiswa kuthebula elingezansi.
“Ithebula lokuqhathanisa ngobubanzi namandla okugeleza kwamandla” ithebula lokuqhathanisa ngobubanzi namandla okugeleza kwamandla
Kungabonakala etafuleni elingenhla ukuthi i-10mil eyodwa nge-single ingathwala i-1A yamanje. Ngakho-ke, ekwakhiweni, uma amandla kagesi engu-2A njengamanje, okungenani ama-vias ama-2 kufanele aboshwe lapho kusetshenziswa ama-10mil vias wokufaka imbobo. Ngokuvamile, lapho kudizayinwa, sizocubungula ukubhola izimbobo eziningi esiteshini samandla ukuze sigcine umkhawulo omncane.
2. Okwesibili, indlela yamandla kufanele ibhekwe. Ngokuqondile, lezi zici ezimbili ezilandelayo kufanele zibhekwe.
(a) Indlela yamandla kufanele ibe mfushane ngangokunokwenzeka. Uma yinde kakhulu, ukwehla kwamandla kagesi kuzoba kubi kakhulu. Ukwehla kwamandla kagesi ngokweqile kuzoholela ekuhlulekeni kwephrojekthi.
(b) Ukwahlukaniswa kwendiza kokuphakelwa kwamandla kuzogcinwa njalo ngangokunokwenzeka, futhi imicu emincane kanye nokwehlukaniswa okuyindilinga akuvunyelwe.
