Isiqingatha somngxuma owenziwe ngesinyithi sithetha ukuba emva komngxuma wokubhobhoza (i-drill, i-gong groove), emva koko i-2 igrunjiwe kwaye imile, kwaye ekugqibeleni isiqingatha somngxuma owenziwe ngesinyithi (groove) sigcinwa.Ukuze ulawule ukuveliswa kweebhodi zetsimbi ezinesiqingatha, abavelisi bebhodi yesekethe badla ngokuthatha amanyathelo athile ngenxa yeengxaki zenkqubo ekudibaneni kweemingxuma ezinesiqingatha ezinentsimbi kunye nemingxuma engaxutywanga.


IiPCBs ezinesiqingatha somngxuma ezinentsimbi zinezicelo ezimbalwa kumashishini ahlukeneyo kuneePCB.Umngxuma onesiqingatha esinesinyithi kulula ukukhupha ubhedu oluzikayo emngxunyeni xa kugaywa, ngoko ke izinga le-scrap kumzi-mveliso webhodi yesekethe liphezulu kakhulu.


Yintoni i ibhodi yesekethe enesiqingatha umngxuma-metalized ingaba?

Ibhodi yesekethe enesiqingatha somngxuma
Inkqubo yokuveliswa kolu hlobo lwebhodi icutshungulwa ngokwenkqubo elandelayo: ukugaya (ukugaya, i-gong groove-plate plating--Image yokukhanya yangaphandle--Pattern plating-Drying--Semi-hole processing--Ukususwa kwefilimu, etching, kunye nokususwa kwetoti--Ezinye iinkqubo--Milo


Le imingxunya isiqingatha metallized ezithile ziphathwa ngale ndlela ilandelayo: zonke metallized isiqingatha-umngxuma PCB imingxunya kufuneka yombiwe kwipatheni emva yokucwenga, kwaye phambi etching, yokomba umngxuma ekudibaneni kweziphelo zombini umngxuma isiqingatha.

1) Isebe lobunjineli lenza inkqubo ye-MI ngokwenkqubo,
2) Intsimbi yesiqingatha-umngxuma isiqingatha sesibini esichithwe kwi-drilling ngexesha lokuqala lokugaya (okanye i-gong), emva kokuba umfanekiso ufakwe, nangaphambi kokutshiza.Kufuneka kuthathelwe ingqalelo ukuba ubhedu luya kubonakaliswa xa i-gong groove yenziwe, kwaye i-drilled half-hole kufuneka ihanjiswe kwiyunithi.
3) Umngxuma wasekunene (umngxuma okwisiqingatha somngxuma): a.Gqibezela ukugaya kuqala, emva koko ujike ibhodi (okanye ulwalathiso lwesibuko);yomba umngxuma wasekhohlo.b.Injongo kukunciphisa ukutsalwa kobhedu lomngxuma kwisiqingatha somngxuma nge-drill, okubangela ukungabikho kobhedu lomngxuma.
4) Ubungakanani bombhobho wokugrumba isiqingatha somngxuma buxhomekeke kwisithuba somgca wecontour.
5) Zoba ifilimu ye-mask ye-solder, sebenzisa i-gong njengendawo yokumisa kwaye uvule ifestile ukunyusa unyango.
