Hauv cov kab mount technology (SMT) cov kab ntau lawm, kev xaiv ntawm lub qhov cub reflow ncaj qha txiav txim siab qhov zoo, kev tsim khoom, thiab kev ntseeg tau ntawm cov khoom. Tau ntsib nrog ntau yam ntawm qhov cub hom thiab kev teeb tsa ntawm kev ua lag luam, tuam txhab lag luam yuav tsum tau txiav txim siab txog kev tshawb fawb thiab tsim nyog raws li lawv tus kheej cov txheej txheem yuav tsum tau ua, ntsuas qhov zoo xws li cov txheej txheem cua sov, qhov kub thiab txias qauv, kev tswj huab cua, muaj peev xwm sib piv, thiab scalability. Qhov no ua kom ntseeg tau tias cov cuab yeej siv peev tsis tawm ntawm qhov sib txuam nrog cov kev xav tau tiag tiag thiab lav cov txheej txheem tsim khoom zoo thiab muaj zog.
Lub hauv paus tseem ceeb rau kev xaiv yog cov khoom ua cov yam ntxwv. Cov khoom sib txawv sib txawv ntawm qhov sib txawv ntawm qhov sib koom ua ke, qhov sib xyaw pob hom, qhov kub thiab txias, thiab kam rau ua rau qhov tsis xws luag. Piv txwv li, cov neeg siv khoom siv hluav taws xob feem ntau siv cov hlau lead- dawb solder thiab yog tus nqi- rhiab heev, yog li cov cua kub convection los yog ntau- cheeb tsam cua qhov cub tuaj yeem raug xaiv kom tau raws li cov qauv ntsuas kub thiab muaj peev xwm. Automotive electronics, kev kho mob hluav taws xob, thiab cov khoom siv tub rog, vim muaj kev ntseeg siab nruj, feem ntau yuav tsum muaj kev tiv thaiv nitrogen los tiv thaiv oxidation thiab tej zaum yuav tsum tau koom nrog lub tshuab nqus tsev reflow kom txo cov voids hauv cov pob qij txha. Rau cov khoom siv nrog cov pob loj hauv qab, xws li BGAs thiab CSPs, lub tshav kub tsis sib xws thiab qhov chaw txias txias yog qhov tseem ceeb tshwj xeeb. Nyob rau hauv rooj plaub no, hybrid infrared / cua kub multi-zone furnace muab lub qhov rais txheej txheem ruaj khov dua.
Kev xaiv cov cua sov txoj kev yog qhov tseem ceeb heev rau kev hloov hluav taws xob thiab kev sib txig sib luag. Cov hluav taws xob hluav taws xob hluav taws xob ua kom sov sai sai, haum rau cov qauv yooj yim thiab cov kab hloov pauv sai, tab sis cov nyhuv thaiv tuaj yeem ua rau qhov sib txawv ntawm qhov kub thiab txias. Cov cua kub convection furnaces, nrog rau lawv yuam kev, tuaj yeem ua tiav qhov kub thiab txias dua, hloov mus rau cov txheej txheem nyuaj thiab ntau - khoom hloov. Hybrid furnaces muab qhov zoo ntawm ob qho tib si, ua tiav qhov sib npaug ntawm cov cua kub ceev thiab tag nrho cov khoom sib xws, ua rau lawv haum rau siab - cov khoom kawg nrog cov txheej txheem nqaim. Qhov tsim nyog ntawm cov txheej txheem cua sov sib txawv yuav tsum raug soj ntsuam ua ke nrog cov khoom siv hluav taws xob faib hluav taws xob thiab lub rooj tsav xwm txheej txheem, thiab qhov rov ua dua ntawm qhov kub thiab txias profiles yuav tsum tau txheeb xyuas los ntawm kev sim.
Qhov kub thiab txias cheeb tsam configuration thiab structural form kuj muaj feem xyuam rau cov kev xaiv. Ntau- cheeb tsam tsim tuaj yeem muab faib ua preheating, tuav, reflow, thiab txias theem, muab qhov zoo -tuning qhov chaw rau complex profiles, thiab feem ntau pom nyob rau hauv nruab nrab - mus rau - siab - kawg cov kab ntau lawm; ib zaug -theem isothermal furnaces tsuas yog tsim nyog rau qis- cov khoom kawg nrog cov txheej txheem siab. Nyob rau hauv cov nqe lus ntawm lub cub tawg zoo, kab rov tav furnaces tau dhau los ua lub hauv paus vim lawv cov qauv paub tab thiab kev saib xyuas yooj yim, ua rau lawv tsim nyog rau loj -scale nruam ntau lawm. Vertical furnaces muaj cov hneev taw me me thiab tsim nyog rau cov txheej txheem tshwj xeeb nrog qhov chaw txwv lossis xav tau kev xa tawm ntsug, tab sis xav tau kev saib xyuas ntxiv rau board tiv thaiv -sway thiab qhov chaw raug. Hais txog kev muaj peev xwm, lub peev xwm theoretical yuav tsum raug xam raws li kev siv txoj hlua conveyor siv ceev, thaj tsam kub thiab lub zog cua sov, nrog cov npoo txaus los tiv thaiv kev hloov pauv yav tom ntej.
Cov txheej txheem tswj huab cua muaj feem cuam tshuam rau vuam zoo thiab cov nqi khiav lag luam. Lub tshuab cua sov muaj peev xwm pib qis thiab tsim nyog rau cov khoom siv dav dav; thaum nitrogen-cov chaw tiv thaiv ua rau kom cov pa roj thiab cov nqi kho cov pa tawm, lawv txhim kho qhov sib koom ua ke zoo thiab kev ntseeg siab, tshwj xeeb tshaj yog rau cov hlau lead- dawb solder thiab nplua - suab soldering. Cov tuam txhab lag luam yuav tsum ntsuas cov txiaj ntsig zoo tiv thaiv cov nqi khiav lag luam thiab ntsuas qhov rov qab los ntawm kev nqis peev rau kev tiv thaiv nitrogen nyob rau hauv ntev - ntau lawm.
Automation thiab kev tuav pov hwm yog lav rau kev tsim khoom tas mus li. Kev thauj khoom thiab tshem tawm tag nrho, kev ntsuas kub hauv online, thiab SPC kev txheeb xyuas cov haujlwm tuaj yeem txo cov kev cuam tshuam tib neeg thiab txhim kho cov txheej txheem kev ruaj ntseg; Modular cua sov chav tsev thiab ceev- tso tawm cov qauv tuaj yeem ua kom luv luv rau kev saib xyuas thiab txo qis peev txheej. Cov chaw tsim khoom tom qab- kev muag khoom muaj peev xwm, cov khoom seem ntawm lub voj voog, thiab kev txhawb nqa kev hloov kho software yuav tsum raug txiav txim siab kom ntseeg tau tias cov cuab yeej tseem nyob hauv qhov zoo thoob plaws hauv nws lub neej.
Feem ntau, xaiv qhov SMT reflow qhov cub tsis yog ib qho teeb meem ntawm kev sib piv cov khoom siv, tab sis nws yog ib qho kev sib koom ua ke raws li cov txheej txheem cov khoom thiab cov tswv yim tsim khoom. Tsuas yog los ntawm kev nkag siab zoo ntawm tus kheej cov kev xav tau, ntsuas qhov zoo thiab qhov tsis zoo ntawm ntau hom qhov cub, thiab xav txog kev nthuav dav yav tom ntej tuaj yeem xaiv cov khoom tsim nyog, ua kom cov txheej txheem ruaj khov thiab tswj tau, kev txhim kho tsis tu ncua ntawm cov khoom zoo, thiab tsim cov txheej txheem txheej txheem rau cov tuam txhab tsim hluav taws xob.
