Yuav ua li cas txhawm rau txhim kho cov txiaj ntsig ntawm kev nplua-pitch CSP thiab lwm yam khoom siv?Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm vuam hom xws li cua kub vuam thiab IR vuam?Ntxiv rau yoj soldering, puas muaj lwm yam txheej txheem soldering rau PTH Cheebtsam?Yuav ua li cas xaiv qhov kub thiab txias thiab tsis kub solder paste?
Vuam yog txheej txheem tseem ceeb hauv kev sib dhos ntawm cov khoom siv hluav taws xob.Yog hais tias nws tsis zoo mastered, tsis tsuas yog ntau yam tsis ua hauj lwm ib ntus yuav tshwm sim, tab sis kuj lub neej ntawm cov pob qij txha yuav raug cuam tshuam ncaj qha.
Reflow soldering tshuab tsis yog tshiab hauv kev tsim hluav taws xob.Cov khoom ntawm ntau lub PCBA boards siv nyob rau hauv peb lub smartphones yog soldered rau lub rooj tsavxwm Circuit Court los ntawm cov txheej txheem no.SMT reflow soldering yog tsim los ntawm melting lub pre-tso solder nto Solder pob qij txha, ib txoj kev soldering uas tsis ntxiv ib qho ntxiv solder thaum lub sij hawm soldering txheej txheem.Los ntawm cov cua sov hauv cov khoom siv, cov cua los yog nitrogen yog rhuab mus rau qhov kub txaus thiab ces cua tshuab mus rau lub rooj tsavxwm Circuit Court uas cov khoom tau pasted, yog li ntawd ob lub Cheebtsam ntawm solder paste solder nyob rau sab yog melted thiab bonded rau. lub motherboard.Qhov kom zoo dua ntawm cov txheej txheem no yog qhov kub thiab txias yog yooj yim los tswj, oxidation yuav zam tau thaum lub sij hawm soldering txheej txheem, thiab cov nqi tsim khoom kuj yooj yim los tswj.
Reflow soldering tau dhau los ua cov txheej txheem tseem ceeb ntawm SMT.Feem ntau ntawm cov khoom ntawm peb lub xov tooj smartphones yog soldered rau lub rooj tsav xwm Circuit Court los ntawm cov txheej txheem no.Cov tshuaj tiv thaiv lub cev nyob rau hauv airflow kom ua tiav SMD vuam;Yog vim li cas vim li cas nws thiaj li hu ua "reflow soldering" yog vim hais tias cov roj circulates nyob rau hauv lub vuam tshuab los ua kom kub siab kom ua tiav lub hom phiaj ntawm vuam.
Reflow soldering cov cuab yeej yog cov cuab yeej tseem ceeb hauv kev sib dhos SMT.Kev sib koom ua ke zoo ntawm PCBA soldering nyob ntawm qhov ua tau zoo ntawm cov khoom siv reflow soldering thiab qhov chaw ntawm qhov kub thiab txias.
Lub tshuab reflow soldering tau ntsib ntau hom kev txhim kho, xws li phaj hluav taws xob cua sov, quartz infrared raj cua sov, infrared cua kub cua sov, yuam cua kub cua sov, yuam cua kub cua sov ntxiv rau nitrogen tiv thaiv, thiab lwm yam.
Kev txhim kho cov kev xav tau rau cov txheej txheem txias ntawm reflow soldering kuj txhawb kev txhim kho ntawm qhov chaw txias ntawm cov khoom siv reflow soldering.Qhov chaw txias txias yog qhov txias txias ntawm chav tsev kub, cua txias rau cov dej txias uas tsim los hloov kho kom tsis muaj hlau lead.
Vim yog kev txhim kho ntawm cov txheej txheem ntau lawm, cov khoom siv reflow soldering muaj cov kev xav tau ntau dua rau kev tswj qhov kub thiab txias, qhov ntsuas kub tsis sib xws hauv cheeb tsam kub, thiab kev sib kis ceev.Los ntawm thawj peb cheeb tsam kub, qhov sib txawv ntawm cov vuam tshuab xws li tsib qhov chaw kub, rau qhov kub thiab txias, xya qhov chaw kub, yim qhov kub thiab txias cheeb tsam tau tsim.
Vim yog qhov txuas txuas ntxiv ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob tau tshwm sim, thiab cov txheej txheem vuam ib txwm tsis tuaj yeem ua tau raws li qhov xav tau.Ua ntej tshaj plaws, cov txheej txheem reflow soldering yog siv nyob rau hauv kev sib dhos ntawm hybrid integrated circuits.Feem ntau ntawm cov khoom sib dhos thiab welded yog nti capacitors, nti inductors, mount transistors thiab diodes.Nrog rau kev txhim kho tag nrho SMT thev naus laus zis tau dhau los ua qhov zoo tshaj plaws, ntau yam ntawm cov khoom siv nti (SMC) thiab cov khoom siv mounting (SMD) tshwm sim, thiab cov txheej txheem reflow soldering tshuab thiab cov cuab yeej siv los ua ib feem ntawm cov tshuab mounting kuj tau tsim raws li, thiab nws daim ntawv thov tau dhau los ua ntau thiab dav.Nws tau raug siv nyob rau hauv yuav luag tag nrho cov khoom siv hluav taws xob, thiab reflow soldering thev naus laus zis kuj tau dhau los ua cov theem hauv qab no ntawm kev txhim kho cov khoom siv.
