1. Iphedi eklanyelwe kufanele ikwazi ukuhlangabezana nezidingo zikasayizi zobude, ububanzi nesikhala sephinikhodi yedivayisi eqondiwe.
Kufanele kuqashelwe ngokukhethekile: iphutha lobukhulu elikhiqizwe iphinikhodi yedivayisi ngokwayo kufanele inakwe ekwakhiweni - ikakhulukazi amadivayisi anembile futhi anemininingwane kanye nezixhumi.

Uma kungenjalo, kungase kuholele kumaqoqo ahlukene ohlobo olufanayo lwamadivayisi, ngezinye izikhathi isivuno sokucubungula i-welding siphezulu, ngezinye izikhathi izinkinga ezinkulu zekhwalithi yokukhiqiza zenzeka!

Ngakho-ke, idizayini ehambisanayo yephedi (efanelekile futhi evamile eklanyweni kasayizi wephedi yedivayisi yabakhiqizi abaningi) ibaluleke kakhulu!

Mayelana naleli phuzu, izidingo ezilula nezindlela zokuhlola yilezi:

Beka idivaysi eqondiwe kuphedi yebhodi le-PCB ukuze uyibone, uma iphinikhodi ngayinye yocingo isendaweni yephedi ehambisanayo.

Ukwakhiwa kwephakheji yale pad ngokuyisisekelo akuyona inkinga enkulu.Ngokuphambene, uma ezinye izikhonkwane zingekho ku-pad, akukuhle.

2. Iphedi eklanyelwe kufanele ibe nophawu olusobala oluqondisayo, okungcono kube uphawu lwe-polarity olutholakala emhlabeni wonke futhi oluhlukaniseka kalula.Uma kungenjalo, lapho lingekho isampula le-PCBA elifanelekayo lereferensi, uma inkampani yangaphandle (ifekthri ye-SMT noma ukukhishwa kwangasese) yenza inqubo yokushisela, izothambekela ekuhlehliseni i-polarity kanye nokushisela okungalungile!

3. Iphedi eklanyelwe kufanele ikwazi ukuhlangabezana nemingcele yokucubungula, izidingo kanye nobuciko befekthri ethile yesekethe ye-PCB ngokwayo.

Isibonelo, usayizi womugqa wephedi, isikhala somugqa, ubude bezinhlamvu nobubanzi obungaklanywa, njll. Uma usayizi we-PCB mkhulu, kunconywa ukuthi uklame ngokuvumelana nenqubo yefekthri ye-PCB edumile nevamile emakethe, ukuze lapho umphakeli we-PCB eshintshwa ngenxa yekhwalithi noma izinkinga zokubambisana kwebhizinisi, bambalwa kakhulu abakhiqizi be-PCB ongakhetha kubo futhi neshejuli yokukhiqiza ibambezelekile.
