8 Umaleko ENIG FR4 Half Hole PCB

Emva kokuba iPCB yenziwe kumngxunya wesiqingatha, umaleko wetin ubekwe emphethweni womngxuma nge-electroplating.Umaleko we-tin usetyenziswa njengomaleko okhuselayo wokwandisa ukuxhathisa kokukrazula kwaye uthintele ngokupheleleyo umaleko wobhedu ukuba uwe eludongeni lomngxuma.Ngoko ke, isizukulwana sokungcola kwinkqubo yokuvelisa ibhodi yesekethe eprintiweyo iyancitshiswa, kwaye umthwalo wokucoca nawo uyancitshiswa, ukwenzela ukuba kuphuculwe umgangatho wePCB egqityiweyo.

Emva kokuba ukuveliswa kwe-PCB ye-half-hole eqhelekileyo kugqityiwe, kuya kubakho iitshiphusi zobhedu kumacala omabini e-half-hole, kwaye iitshiphusi zobhedu ziya kubandakanyeka kwicala langaphakathi lomngxuma wesiqingatha.Umngxuma isiqingatha isetyenziswa njengomntwana PCB, indima umngxuma isiqingatha kwinkqubo PCBA, uya kuthatha isiqingatha umntwana PCB, ngokunika isiqingatha umngxuma yokuzaliswa inkonkxa ukwenza isiqingatha master ipleyiti welded kwibhodi enkulu. , kunye nesiqingatha somngxuma kunye ne-copper scrap, iya kuchaphazela ngokuthe ngqo i-tin, ichaphazela i-welding ngokuqinileyo yephepha kwi-motherboard, kwaye ichaphazela imbonakalo kunye nokusetyenziswa komsebenzi wonke womatshini.

Umphezulu wesiqingatha somngxuma unikwe umaleko wesinyithi, kwaye ukuhlangana kwesiqingatha somngxuma kunye nomphetho womzimba ngokulandelelana kubonelelwa ngesikhewu, kwaye umphezulu wesikhewu yinqwelomoya okanye umphezulu wesikhewu yi-gap. indibaniselwano yendiza kunye nomphezulu womphezulu.Ngokunyusa umsantsa kuzo zombini iziphelo zomngxuma wesiqingatha, iitshiphusi zobhedu ekudibaneni komngxuma wesiqingatha kunye nomphetho womzimba ziyasuswa ukuze zenze iPCB egudileyo, ngokufanelekileyo ukuthintela iitshiphusi zobhedu ezihlala kumngxuma wesiqingatha, ziqinisekisa umgangatho we-PCB. I-PCB, kunye ne-welding ethembekileyo kunye nomgangatho wembonakalo ye-PCB kwinkqubo ye-PCBA, kunye nokuqinisekisa ukusebenza komatshini wonke emva kwendibano elandelayo.
