Ukurikije inzira, stencil ya pcb irashobora kugabanywamo ibyiciro bikurikira:

1. Solder paste stencil: Nkuko izina ribigaragaza, ikoreshwa mugukaraba paste. Shushanya umwobo mugice cyicyuma gihuye nudupapuro twibibaho bya pcb. Noneho koresha paste paste kugirango ushire ku kibaho cya PCB unyuze kuri stencil. Mugihe cyo gucapa ibicuruzwa byagurishijwe, shyira paste yuwagurishije hejuru yigitereko, mugihe ikibaho cyumuzunguruko gishyirwa munsi yigitereko, hanyuma ukoreshe icyuma gisakara kugirango ushireho paste yagurishijwe neza kumyobo ya stencil (paste yuwagurishijwe azakurwa muri icyuma gishashe. Shira ibice bya SMD, hanyuma kugurisha kugurisha birashobora gukorwa kimwe, kandi ibice byacometse bigurishwa intoki.

2. Ikaramu itukura ya pulasitike: Gufungura byafunguwe hagati yimyenda ibiri yibigize ukurikije ubunini n'ubwoko bw'igice. Koresha gutanga (gutanga ni ugukoresha umwuka wugarijwe kugirango werekane kole itukura kuri substrate ukoresheje umutwe wihariye utanga) kugirango werekane kole itukura ku kibaho cya PCB unyuze mucyuma. Noneho shyira akamenyetso kubigize, hanyuma nyuma yibigize bifatanye neza na PCB, ucomekeshe ucomeka hanyuma unyure hamwe kugurisha hamwe.

3. Ikirangantego cyibiri: Iyo PCB ikeneye kozwa hamwe na paste yagurishijwe hamwe na kole itukura, noneho hagomba gukoreshwa ikaramu yuburyo bubiri. Ikirangantego cyibice bibiri kigizwe na stencil ebyiri, imwe isanzwe ya laser hamwe na stencil imwe. Nigute ushobora kumenya niba wakoresha stencil ikandagiye cyangwa kole itukura kuri paste? Banza wumve niba woza mbere yo kugurisha paste cyangwa kugurisha umutuku. Niba paste yuwagurishijwe ashyizwe mubikorwa mbere, hanyuma umugurisha wa paste wacurujwe ukorwa muburyo busanzwe bwa lazeri, hanyuma ikariso itukura ikozwe muburyo bwo gukandagira. Niba glue itukura ikoreshejwe mbere, noneho ikariso itukura ikozwe muburyo busanzwe bwa lazeri, hanyuma umugurisha paste ikozwe mububiko.
