Malinga ndi ndondomekoyi, pcb stencil ikhoza kugawidwa m'magulu awa:

1. Stencil ya solder: Monga momwe dzinalo likusonyezera, imagwiritsidwa ntchito kupaka phala la solder.Dulani mabowo muchitsulo chomwe chimagwirizana ndi mapepala a pcb board.Kenako gwiritsani ntchito solder phala kuti mupititse ku bolodi la PCB kudzera pa stencil.Mukasindikiza phala la solder, gwiritsani ntchito phala la solder pamwamba pa stencil, pamene bolodi la dera limayikidwa pansi pa stencil, ndiyeno gwiritsani ntchito chopukutira kuti muphwanye phala la solder mofanana pamabowo a stencil (phala la solder lidzafinyidwa kuchokera ku zitsulo mauna kutsika pansi mauna ndi kuphimba bolodi dera).Matani zigawo za SMD, ndi reflow soldering ikhoza kuchitidwa mofanana, ndipo zigawo za plug-in zimagulitsidwa pamanja.

2. Stencil ya pulasitiki yofiira: Kutsegula kumatsegulidwa pakati pa mapepala awiri a chigawocho malinga ndi kukula ndi mtundu wa gawolo.Gwiritsani ntchito kugawa (kutulutsa ndiko kugwiritsa ntchito mpweya woponderezedwa kuloza guluu wofiira ku gawo lapansi kudzera pamutu wapadera woperekera) kuti muloze guluu wofiira ku bolodi la PCB kudzera muukonde wachitsulo.Ndiye chizindikiro zigawo zikuluzikulu, ndipo pambuyo zigawo mwamphamvu Ufumuyo PCB, pulagi mu zigawo pulagi-mu ndi kudutsa yoweyula soldering pamodzi.

3. Stencil yapawiri: Pamene PCB ikufunika kupakidwa ndi solder phala ndi guluu wofiira, ndiye kuti stencil yapawiri iyenera kugwiritsidwa ntchito.Cholembera chapawiri chimapangidwa ndi zolembera ziwiri, cholembera cha laser wamba ndi chopondapo chimodzi.Kodi mungadziwe bwanji ngati mugwiritse ntchito stencil kapena guluu wofiira pa phala la solder?Choyamba mvetsetsani ngati mutsuke phala la solder kapena guluu wofiira poyamba.Ngati phala la solder likugwiritsidwa ntchito poyamba, ndiye kuti cholembera cha solder chimapangidwa kukhala cholembera wamba cha laser, ndipo cholembera chofiira chimapangidwa kukhala chopondapo.Ngati guluu wofiira agwiritsidwa ntchito poyamba, ndiye kuti stencil yofiira imapangidwa kukhala stencil wamba wa laser, ndipo solder pastencil imapangidwa kukhala chopondapo.
