Xyoo tsis ntev los no, laser ua thev naus laus zis tau nrov npe, thiab ntau thiab ntau qhov kev lag luam tau xaiv laser kev ua haujlwm nyob rau hauv cov txheej txheem ntawm kev tsim kho, uas muab cov tshuab laser ua qhov chaw dav dav rau kev txhim kho thiab ntau dua tshiab thiab tshawb nrhiav. Ntawm lawv, laser solder paste welding yog lwm yam tshiab ntawm cov txheej txheem hauv thaj teb ntawm laser vuam tshuab. Zichen solder paste automatic laser soldering tshuab yog vuam tshuab uas siv cov tshuab hluav taws xob semiconductor laser ua cov khoom siv cua sov los ua kom kub siab tshwj xeeb ham muab tshuaj rau laser vuam. Nws muaj vuam nrawm nrawm, vuam vuam zoo zoo, ob peb vuam kev tsis sib haum, thiab lub siab vuam ruaj khov. Nws tuaj yeem siv dav hauv tsheb tsheb Electronics kev lag luam, semiconductor kev lag luam thiab cov neeg siv khoom siv hluav taws xob kev lag luam, xws li kev sib txuas lus kho qhov muag, lub koob yees duab ccm modules, tsheb kho hluav taws xob, FPC mos cov laug cam, cov txuas txuas, cov khoom siv hluav taws xob thiab lwm yam khoom hauv cov txheej txheem vuam.
Vim kev txhim kho tsis tu ncua ntawm miniaturization nyob rau hauv lub tsheb hluav taws xob, cov khoom siv hluav taws xob, thiab cov xov tooj ntawm cov neeg siv khoom siv hluav taws xob kev lag luam, cov pob qij txha me me, qhov siab ua kom muaj zog, thiab qhov chaw muaj cua sov me nyob ib puag ncig cov ntsiab lus kev xav tau. Lub tshuab hluav taws xob ib txwm siv hlau tsis yog yooj yim rau kev khiav lag luam xwb, tab sis kuj siv lub tshuab vuam vuam tsis zoo muaj qhov ua haujlwm tsis zoo, qis dua kev ua haujlwm tsis muaj zog, kev ua haujlwm tsis zoo ntawm lub nplhaib weld thiab qhov txuas welded, thiab nws yooj yim ua rau" desoldering" , yog li nws yog qhov nyuaj kom tau raws li qhov yuav tsum tau ua.
Lub precision tsis siv neeg laser soldering tshuab yog ib hom ntawm laser vuam cov khoom uas sib txuas lub siab lub zog laser nqaj mus rau hauv hluav taws xob kho qhov muag, thiab tom qab kev sib kis ntev, nws yog collimated mus rau hauv lub teeb thaum uas tig mus los ntawm lub collimator, thiab tom qab ntawd tsom mus rau qhov chaw ua haujlwm rau vuam. Rau cov seem uas nyuaj rau kis tau los ntawm vuam, hloov tau yooj yim tsis txuas mus cuag vuam yog siv, uas muaj kev hloov pauv ntau dua.
Laser soldering txheej txheem
Cov kev tshawb fawb hauv domestic ntawm laser technology feem ntau tsom rau vuam ceev, laser fais fab, defocusing nqi, laser pulse waveform thiab tiv thaiv cov roj ntws thiab lwm yam kev ntsuas ntawm txhua txoj kev vuam, thiab kev tshawb fawb ntxiv txog cov khoom kho tshuab, microstructure evolution thiab kev cai ntawm welded pob qij txha. Qhov kev tshawb fawb nyob hauv. Laser solder paste vuam yog qhov tshwj xeeb laser vuam tshuab uas sib txuas cov laser ua kom muaj cua sov nrog cov tsoos tiaj tiaj vuam. Txoj ntsiab cai ua haujlwm ntawm laser solder paste soldering yog: siv cov kab hluav taws xob rau qee qhov yaj kom cov tshuaj pleev rau ntawm lub workpiece kom ua rau soldered, thiab tom qab ntawd cov ham muab tshuaj npog cov workpiece ncoo thiab txias ua kom zoo nkauj thiab puag ncig kev sib koom tes. Vim tias lub cheeb tsam melting yog qhov nqaim, vuam tsis xws luag xws li shrinkage thiab roj cav tau zam.
Laser soldering kho kho tsis zoo
Laser soldering siv dav, tab sis cov txheej txheem vuam feem ntau nrog vuam tsis xws luag xws li cov kab nrib pleev, vuam pores thiab spatter. Txoj kev tshawb fawb tau ua tiav ntawm nws hauv tsev thiab txawv teb chaws. Lawv siv oscillation, txuas ntxiv, mem tes thiab lwm txoj hauv kev los ua ke nrog laser vuam. Thaum kawm txog txoj ntsiab cai, lawv kuj tseem ceeb qhov tseem ceeb rau kev sib xyaw nrog cov khoom siv khoom lag luam thiab nquag siv cov khoom tshiab los txhawb lawv tus kheej kev tshawb fawb. Kev tshawb fawb muaj kev ua haujlwm siab.
