FAQ
Yintoni umahluko ophambili phakathi kokubalwa kwamaleko e-PCB okuqhelekileyo nokusebenzayo?
Ungayifumana inani leeleya eziqhelekileyo kumzobo wakho wokuqokelelana. Ikuxelela ukuba zingaphi iileya zobhedu ezikwibhodi yakho. Inani leeleya ezisebenzayo libala kuphela iileya ezithwala imiqondiso, amandla, okanye umhlaba. Iileya ezingezizo okanye ezingasetyenziswanga azibalwa njengezisebenzayo.
Kutheni kukho iileya ezingaqhelekanga kuyilo lwePCB?
Abavelisi bafaka iileya ezingezizo ezokwenyani ukuze ibhodi ihlale ilungelelene okanye incede ekufudumaleni. Ezi leya azithwali zimpawu okanye amandla. Uzifuna ukuze ufumane amandla, hayi ngenxa yezizathu zombane.
Ngaba ukubalwa kwamaleko aphezulu kunokuphucula ukusebenza kwePCB yam?
Ayizizo zonke iileya ezongezelelweyo ezinceda ibhodi yakho isebenze ngcono. Ziileya ezisebenzayo kuphela ezenza isekethe yakho isebenze kakuhle. Iileya ezingezizo ezincedayo azincedi ngemiqondiso okanye amandla. Kufuneka ugxile kwinto eyenziwa yileya nganye kuyilo lwakho.
Ndingajonga njani ukuba umaleko uyasebenza na kuyilo lwam?
Jonga uyilo lwePCB yakho. Ukuba umaleko uneempawu zesignali, iiplani zamandla, okanye iiplani zomhlaba, uyasebenza. Iilayini ezine-copper fill kuphela okanye ezingenayo i-routing azisebenzi.
Ngaba ndifanele ndixelele umenzi wam ukubala iileya ezisemgangathweni nezisebenzayo?
Ewe. Kufuneka usoloko unika umenzi wakho amanani omabini. Oku kuyabanceda bazi into oyifunayo kwaye kuthintele iimpazamo. Unxibelelwano oluhle lukunika iibhodi ezingcono.
