SMD ua ntej yuav tsum tau khawb ib txheej ntawm solder paste rau saum lub pcb ncoo, solder paste luam ntawv yuav tsum tau ua tom qab qhov zoo ntawm qhov kev xeem, kuaj lub npe ntawm lub tshuab yog hu ua spi (solder paste kuaj tshuab), lub ntsiab kev ntsuam xyuas ntawm solder paste luam ntawv seb puas muaj offset, rub lub hau, lub thickness thiab flatness, thiab lwm yam, vim hais tias qhov zoo ntawm solder paste luam ntawv ncaj qha cuam tshuam rau qhov zoo ntawm qhov zoo ntawm weld qab, kev lag luam weld yog vim li cas rau cov neeg pluag. ntau tshaj 60% ntawm cov teeb meem yog cov luam ntawv ntawm solder paste!Ua los ntawm ntau tshaj 60% ntawm qhov ua rau cov neeg pluag soldering nyob rau hauv kev lag luam yog cov teeb meem ntawm solder paste printing, txaus los ua pov thawj tias qhov tseem ceeb ntawm solder paste printing test.
Lub ntsiab lus ntawm SPI los ntawm tus nqi
Solder Paste Printing Inspection (SPI) thiab AOI kev ntsuam xyuas muaj tus nqi ncaj nraim, ncaj nraim los ntawm tus nqi los ntawm lo lus tuaj yeem nkag siab zoo, ncaj qha los ntawm qhov yuav tshwm sim, kuj tuaj yeem dhau los ua qhov kev vam meej, qhov siab dua qhov ncaj los ntawm tus nqi, cov khoom tsim tau ntau dua. thiab muaj peev xwm ntau lawm, yog tias qhov ncaj los ntawm tus nqi qis, nws txhais tau tias cov txheej txheem tsis ua haujlwm, cuam tshuam rau lub peev xwm ntawm kev ua haujlwm.
Qhov tseem ceeb ntawm kev ncaj ncees los ntawm kev tswj tus nqi
Ncaj nraim los ntawm tus nqi kuj qhia txog qhov kev vam meej, qhov siab dua qhov ncaj los ntawm tus nqi, qhov siab dua ntawm cov tshuab tsim khoom, qhov tshwm sim ntawm kev ncaj qha, thiab tsis tas li qhia qhov tsis zoo lossis tsis ncaj ncees lawm, ncaj qha los ntawm tus nqi siab, kev tsim khoom siab, muaj peev xwm siab, ncaj qha los ntawm tus nqi qis, tsis muaj kev siv tshuab ntau lawm, thiab yuav cuam tshuam rau kev tsim khoom thiab cov nqi siv sijhawm, tab sis kuj ua rau tus nqi ntawm cov neeg ua haujlwm ntau dua, cov nqi khoom siv rau kev saib xyuas.Yog li ntawd, qhov ncaj-los ntawm kev tswj tus nqi rau kev cog qoob loo tsis tsuas yog sawv cev rau qib ntawm kev tsim khoom zoo, tab sis kuj cuam tshuam rau kev tsim khoom ntawm lub Hoobkas.
Cov xwm txheej cuam tshuam spi los ntawm tus nqi
Solder Paste
Yog hais tias lub liquidity ntawm solder paste loj dhau lawm, nws yog ib qho yooj yim uas yuav ua rau lub solder paste hloov thiab vau nyob rau hauv lub ncoo, uas ua rau cov luam ntawv tsis zoo, peb yuav tsum tau siv lub solder paste kom tag nrho rov qab mus rau qhov kub thiab txias.
Squeegee
Squeegee siab, ceev, lub kaum sab xis yuav cuam tshuam tus nqi ntawm solder paste luam tawm ntawm lub pcb ncoo (thickness thiab flatness), yog hais tias lub thickness yog ntau dhau los yog tsawg heev, nws yuav ua rau luv luv Circuit Court los yog khoob soldering.
Stencil qhov luaj li cas thiab qhov smoothness ntawm lub qhov phab ntsa yuav cuam tshuam rau solder paste seepage, thiab yog hais tias lub stencil qhov phab ntsa muaj plaub hau, nws kuj yuav yooj yim ua rau solder paste residue.
