Ufakelo olululo lwamacandelo e-elektroniki kwi-PCB lubalulekile ekunciphiseni iziphene zokuthengisela. Xa kulungiselelwa izixhobo ze-elektroniki, gwema iindawo ezinexabiso eliphezulu lokuphambuka kunye noxinzelelo oluphezulu lwangaphakathi. Ukusabalalisa amacandelo ngokulinganayo, ngakumbi abo bane-conductivity ephezulu ye-thermal. Kuphephe ukusebenzisa ii-PCB ezinkulu kakhulu ukuthintela ukwanda kunye nokuncipha. Ihlwempu uyilo loyilo lwePCB inokuchaphazela ukwenziwa kunye nokuthembeka kwePCB. Abaqulunqi abaninzi, abajolise ekwandiseni ukusetyenziswa kwendawo yebhodi yesekethe, babeka amacandelo kufutshane nemida ngokusemandleni. Lo mkhuba unokudala imingeni ebalulekileyo yokuvelisa kunye nendibano ye-PCBA, nokuba indibano ye-solder ingenzeki.
Impembelelo yoYilo lweCandelo loMda:
I-1.I-Board Edge Milling: Izixhobo ezibekwe kufutshane kakhulu kumphetho webhodi zinokuthi zenziwe ngeepads zazo ngexesha lokubunjwa. Ngokuqhelekileyo, umgama we-pad-to-edge kufuneka ube mkhulu kune-0.2mm. Ngaphandle koko, iipads kumacandelo eedge ebhodini zinokucolwa, okwenza ukuba indibano elandelayo ingenzeki.
2. Ibhodi yebhodi ye-V-CUT: Ukuba ibhodi yebhodi yi-V-CUT, amacandelo kufuneka abekwe ngakumbi kude nomda, njengoko i-V-CUT blade idlula phakathi kwebhodi. Ngokuqhelekileyo, amacandelo kufuneka abe ngaphezu kwe-0.4mm kude nomda we-V-CUT; ngaphandle koko, i-V-CUT blade inokonakalisa iipads, ukwenza i-soldering ingenzeki.
3. Ukuphazamiseka kweCandelo: Xa amacandelo abekwe kufuphi kakhulu nomphetho, anokuphazamisa ukusebenza kwezixhobo zokuhlanganisa ngokuzenzekelayo, ezifana ne-wave soldering okanye i-reflow soldering machines.
4. Ukonakaliswa kweZixhobo kwiiNgxelo: Ukusondela kwamacandelo kumgca, amandla amakhulu okuphazamisa izixhobo zendibano. Ngokomzekelo, ii-capacitors ezinkulu ze-electrolytic kufuneka zibekwe phambili ukusuka kumda ngenxa yokuphakama kwazo.
5. Umonakalo wecandelo Ngexesha lokwahlula kwePhaneli: Emva kokuba indibano yemveliso igqityiwe, iipaneli kufuneka zihlulwe. Amalungu abekwe kufutshane kakhulu kumphetho angonakala ngexesha lokwahlula. Lo monakalo unokuba ngamaxesha athile, wenze kube nzima ukuwubona kunye nokusombulula ingxaki.
