I. Mitundu yosindikizira ya stencil
1. Makina osindikizira a Stencil
Makina osindikizira pamanja ndi njira yosavuta komanso yotsika mtengo yosindikizira.Kuyika kwa PCB ndikuchotsa kumachitika pamanja, squeegee imatha kugwiritsidwa ntchito pamanja kapena kumangirizidwa pamakina, ndipo ntchito yosindikiza imachitika pamanja.PCB ndi zitsulo mbale parallelism mayikidwe kapena m'mphepete mwa bolodi kuonetsetsa udindo zimadalira luso woyendetsa, kotero PCB aliyense kusindikizidwa, magawo kusindikiza adzafunika kusintha ndi kusintha.
2. Makina osindikizira a semi-automatic
Makina osindikizira a semi-automatic panopa ndi omwe amagwiritsidwa ntchito kwambiri pa makina osindikizira, ali ofanana kwambiri ndi makina osindikizira amanja, kuika ndi kuchotsa ma PCB kumadalirabe ntchito yamanja, kusiyana kwakukulu ndi makina osindikizira ndi chitukuko cha mutu wosindikizira, iwo. amatha kuwongolera liwiro losindikiza, kuthamanga kwa squeegee, ngodya ya squeegee, mtunda wosindikizira ndi phula losalumikizana, mabowo a zida kapena m'mphepete mwa PCB akugwiritsidwabe ntchito kuyika, pomwe dongosolo lachitsulo lachitsulo lothandizira ogwira ntchito Kumaliza bwino kwa PCB ndi kusintha kwazitsulo zachitsulo. .
3. Makina osindikizira athunthu
Phala la solder limasindikizidwa pamapepala a zigawo zomwe zili pa bolodi loyambira, koma masiku ano kukula kwa zigawo zomwe zimayikidwa pamwamba zikucheperachepera, kotero kuti mapangidwe a board base board ndi ochepa komanso abwino.Chifukwa chake, kulondola komanso luso la kusindikiza kwa solder paste kuyenera kusinthidwa kwambiri.Masiku ano, ambiri opanga zinthu zamagetsi amagwiritsa ntchito makina osindikizira a solder phala kuti apange zinthu za SMT, ndipo kuyika kwa PCB kumachitika ndi lamba wonyamulira m'mphepete, ndi magawo azinthu monga liwiro la squeegee, kuthamanga kwa squeegee, kutalika kwa kusindikiza, ndi osalumikizana nawo mayendedwe onse akhoza programmable.
Kuyika kwa PCB kumachitika pogwiritsa ntchito mabowo oyika kapena m'mphepete mwa bolodi, ndipo zida zina zimatha kugwiritsa ntchito machitidwe a masomphenya kuti agwirizane ndi PCB ndi mbale yachitsulo, yomwe imachotsa zolakwika zomwe zimayambitsidwa ndi kuyika m'mphepete pogwiritsa ntchito machitidwe owoneka bwino, ndikupanga malo osavuta, ndi chitsimikiziro choyika pamanja chosinthidwa ndi kachitidwe ka masomphenya.Makina osindikizira atsopano a solder paste ali ndi magalasi apakanema kuti aziwunika momwe makina amasindikizira ndikuwongolera nthawi iliyonse.
II.Kukonza chosindikizira cha stencil
Chotsani squeegee, gwiritsani ntchito pepala lopukuta lapadera loviikidwa mu ethanol ya anhydrous, pukutani squeegee, kenaka muyike pamutu wosindikizira kapena mumalandira mu nduna ya zida.
Kuyeretsa stencil, pali njira ziwiri.
Njira 1: Kutsuka makina ochapira.Kutsuka zida ndi template, kuyeretsa kwenikweni ndikwabwino kwambiri.
Njira 2:Kuyeretsa pamanja.
Gwiritsani ntchito pepala lopukuta lapadera kuti mugwiritse ntchito ethanol ya anhydrous, phala la solder lidzayeretsedwa, ngati kutsekedwa kwa dzenje kutayikira, kupezeka ndi mswachi wofewa, musabaya ndi singano yolimba.
Gwiritsani ntchito mfuti yoponderezedwa kuti muwombere zotsalira mu dzenje lotayirira la template.
Ikani template pamakina odzaza phala, apo ayi mulandire mu kabati ya zida.
