Stencil Stencil ndi njira yoyika phala la solder pamapadi
PCB imakhazikitsa maulumikizidwe amagetsi.
Imapindula ndi chinthu chimodzi, phala la solder lopangidwa ndi zitsulo za solder ndi flux.
Zida ndi zida zomwe zimagwiritsidwa ntchito panthawiyi ndi ma stencil a laser, phala la solder ndi osindikiza a solder paste.
Kuti mukwaniritse chophatikizira chabwino cha solder, voliyumu yolondola ya solder paste iyenera kusindikizidwa, zigawozo ziyenera kuyikidwa pamapadi olondola, phala la solder liyenera kunyowa bwino pa bolodi, liyeneranso kukhala loyera mokwanira kuti SMT stencil. kusindikiza.
Pogwiritsa ntchito ukadaulo wa laser stencil, mutha kupanga zolembera zolimba pamitengo, plexiglass, polypropylene kapena makatoni oponderezedwa ambiri opopera, kutengera zosowa zanu.
Kuti muthe kugulitsa zigawo za SMD pa bolodi la dera, payenera kukhala laibulale yokwanira ya solder.
Nkhope zomaliza pama board ozungulira, monga HAL, nthawi zambiri sizokwanira.
Chifukwa chake, phala la solder limagwiritsidwa ntchito pamapadi a zigawo za SMD.
Phala limagwiritsidwa ntchito pogwiritsa ntchito stencil yachitsulo ya laser.Izi nthawi zambiri zimatchedwa template ya SMD kapena template.
Sungani zida za SMD kuti zisagwe pa bolodi
Panthawi yowotcherera, amagwiridwa ndi zomatira.
Zomatira zitha kugwiritsidwanso ntchito pogwiritsa ntchito template yachitsulo chodulidwa ndi laser.
