Icyuma cya PCBirashobora kugabanywa muburyo bukurikira ukurikije inzira:

1. Solder paste stencil: Nkuko izina ribigaragaza, ikoreshwa mugukoresha paste.Shushanya umwobo mu gice cyicyuma gihuye nudupapuro ku kibaho cya PCB.Noneho koresha paste paste kugirango ucapishe ku kibaho cya PCB unyuze kuri stencil.Mugihe ucapisha ibicuruzwa byagurishijwe, shyira paste yo kugurisha hejuru yikibaho, hanyuma ushire ikibaho cyumuzingi munsi yikibaho.Noneho koresha scraper kugirango usibe paste yuwagurishije neza hejuru yumwobo wa stencil (paste yuwagurishije izasohokera muri stencil iyo ikubiswe) itemba kuri mesh hanyuma utwikire ikibaho cyumuzunguruko).Ongeraho ibice bya SMD hanyuma ubigaragaze hamwe, kandi ibice byacometseho intoki.

2. Icyuma gitukura cya pulasitike itukura: Umwobo wafunguwe hagati yimyenda ibiri yibigize ukurikije ubunini n'ubwoko bw'igice.Koresha gutanga (gutanga ni ugukoresha umwuka wugarije kugirango werekane kole itukura kuri substrate ukoresheje umutwe wihariye wo gutanga) kugirango ushire kole itukura ku kibaho cya PCB unyuze mucyuma.Noneho shyira ibice, hanyuma nyuma yibigize bifatanye neza na PCB, shyira mubice byacometse hanyuma unyuze kugurisha.

3. Ikirangantego cyibikorwa bibiri: Mugihe ikibaho cya PCB gikeneye gusiga irangi hamwe na paste yagurishijwe hamwe na kole itukura, noneho hagomba gukoreshwa ikaramu yuburyo bubiri.Inzira ebyiri zikoreshwa mubyuma bigizwe nicyuma bibiri, icyuma gisanzwe cya laser nicyuma kimwe cyicyuma.Nigute ushobora kumenya niba wakoresha urwego rwurwego rwo kugurisha paste cyangwa urwego rwurwego rwa kole itukura?Banza wumve niba ugomba gushira paste kugurisha cyangwa glue itukura mbere.Niba uwagurishije paste yambere abanza gukoreshwa, noneho ikariso yumugurisha izakorwa muburyo busanzwe bwa laser, hanyuma ikariso itukura ikorwe ikorwe murwego.Niba ubanze ushyireho kole itukura, hanyuma ikariso itukura izakorwa muburyo busanzwe bwa lazeri, hanyuma uwagurishije paste yerekana ibicuruzwa azakorwamo urwego.
