Stencil Stencil ke mokhoa oa ho beha solder pente holim'a liphahlo
PCB e theha likhokahano tsa motlakase.
E finyelloa ka thepa e le 'ngoe, pente ea solder e nang le tšepe ea solder le flux.
Thepa le lisebelisoa tse sebelisoang mothating ona ke li-stencil tsa laser, paste ea solder le liprinta tsa solder paste.
Ho kopana le motsoako o motle oa solder, molumo o nepahetseng oa solder paste o hloka ho hatisoa, likaroloana li lokela ho behoa ka liphaepheng tse nepahetseng, pente ea solder e hloka ho koloba hantle holim'a boto, hape e lokela ho hloeka ka ho lekaneng bakeng sa stencil ea SMT. khatiso.
U sebelisa theknoloji ea laser stencil, u ka etsa li-stencil tse tšoarellang holim'a lehong, plexiglass, polypropylene kapa khateboto e hatisitsoeng bakeng sa li-sprays tse ngata, ho latela litlhoko tsa hau.
Ho khona ho solder likarolo tsa SMD ka boto ea potoloho, ho tlameha ho ba le laeborari e lekaneng ea solder.
Lifahleho tsa ho qetela libotong tsa potoloho, joalo ka HAL, hangata ha lia lekana.
Ka hona, pente ea solder e sebelisoa ho liphahlo tsa likarolo tsa SMD.
Peista e sebelisoa ho sebelisoa stencil ea tšepe ea laser cut.Hangata sena se bitsoa template kapa template ea SMD.
Boloka likarolo tsa SMD hore li se ke tsa thella botong
Nakong ea ts'ebetso ea welding, li ts'oaroa ka sekhomaretsi.
Sekhomaretsi se ka boela sa sebelisoa ho sebelisoa template ea tšepe ea laser-cut.
