Wave soldering chaw tsim tshuaj paus Chengyuan yuav qhia rau koj tias yoj soldering muaj nyob rau ntau xyoo lawm, thiab raws li lub ntsiab txoj kev ntawm soldering Cheebtsam, nws tau ua lub luag haujlwm tseem ceeb hauv kev loj hlob ntawm kev siv PCB.
Muaj kev thawb loj heev los ua cov khoom siv hluav taws xob me me thiab ua haujlwm zoo dua, thiab PCB (lub plawv ntawm cov khoom siv no) ua rau qhov no ua tau.Cov qauv no kuj tau tsim cov txheej txheem tshiab soldering ua lwm txoj hauv kev yoj soldering.
Ua ntej Wave Soldering: PCB Assembly History
Soldering raws li cov txheej txheem ntawm kev koom nrog cov khoom hlau yog xav tias tau tshwm sim sai tom qab kev tshawb pom ntawm tin, uas tseem yog cov tseem ceeb hauv cov khoom siv niaj hnub no.Ntawm qhov tod tes, thawj PCB tau tshwm sim hauv xyoo pua 20th.German inventor Albert Hansen tuaj nrog lub tswv yim ntawm lub dav hlau multilayer;muaj xws li insulating txheej thiab ntawv ci conductors.Nws kuj tau piav qhia txog kev siv lub qhov hauv cov khoom siv, uas yog qhov tseem ceeb tib txoj kev siv niaj hnub no rau kev sib txuas ntawm lub qhov.
Thaum Ntiaj Teb Tsov Rog II, kev txhim kho ntawm cov khoom siv hluav taws xob thiab hluav taws xob tau tshwm sim thaum lub teb chaws nrhiav kev txhim kho kev sib txuas lus thiab qhov tseeb lossis qhov tseeb.Tus neeg tsim khoom ntawm PCB niaj hnub no, Paul Eisler, tau tsim cov txheej txheem hauv xyoo 1936 rau kev koom nrog cov ntawv ci tooj liab rau lub iav insulating substrate.Tom qab ntawd nws tau qhia yuav ua li cas sib sau xov tooj cua ntawm nws lub cuab yeej.Txawm hais tias nws cov laug cam siv xaim los txuas cov khoom sib txuas, cov txheej txheem qeeb, kev tsim ntau ntawm PCBs tsis tas yuav tsum tau ua thaum lub sijhawm.
Wave Welding to the Rescue
Xyoo 1947, lub transistor tau tsim los ntawm William Shockley, John Bardeen, thiab Walter Brattain ntawm Bell Laboratories hauv Murray Hill, New Jersey.Qhov no tau ua rau txo qhov loj ntawm cov khoom siv hluav taws xob, thiab kev txhim kho tom ntej hauv etching thiab lamination tau ua rau txoj hauv kev rau qib qib soldering.
Txij li thaum cov khoom siv hluav taws xob tseem nyob hauv qhov, nws yog qhov yooj yim tshaj los muab cov khoom siv rau tag nrho lub rooj tsavxwm ib zaug, tsis yog soldering lawv tus kheej nrog cov hlau soldering.Yog li, yoj soldering tau yug los los ntawm kev khiav tag nrho lub rooj tsavxwm dhau "nthwv dej" ntawm solder.
Niaj hnub no, yoj soldering yog ua los ntawm lub tshuab yoj soldering.Cov txheej txheem suav nrog cov kauj ruam hauv qab no:
1. Melting - Lub solder yog rhuab mus txog 200 ° C ces nws ntws yooj yim.
2. Kev Tu - Ntxuav cov khoom kom paub tseeb tias tsis muaj qhov cuam tshuam los tiv thaiv cov hlau los ntawm kev sib txuas.
3. Muab tso rau - Muab lub PCB kom zoo kom paub meej tias cov khoom siv mus txog txhua qhov ntawm lub rooj tsavxwm.
4. Daim ntawv thov - Solder yog siv rau lub rooj tsavxwm thiab tso cai rau ntws mus rau txhua qhov chaw.
Yav Tom Ntej ntawm Wave Soldering
Wave soldering yog ib zaug uas feem ntau siv cov txheej txheem soldering.Qhov no yog vim hais tias nws ceev yog zoo dua li phau ntawv soldering, yog li realizing lub automation ntawm PCB los ua ke.Cov txheej txheem yog tshwj xeeb tshaj yog zoo ntawm soldering ceev heev, zoo spaced los ntawm lub qhov.Raws li qhov kev thov rau cov PCBs me me ua rau kev siv ntau cov boards thiab cov khoom siv saum npoo av (SMDs), ntau cov txheej txheem soldering yuav tsum tau tsim.
Qhov no ua rau txoj kev xaiv soldering qhov twg cov kev sib txuas yog soldered tus kheej, xws li hauv tes soldering.Kev nce qib hauv cov neeg hlau uas tau nrawm dua thiab meej dua li kev tuav vuam tau ua kom muaj kev ua haujlwm ntawm txoj kev.
Wave soldering tseem yog cov txheej txheem ua tau zoo vim nws qhov nrawm thiab hloov tau mus rau cov qauv tsim PCB tshiab uas nyiam siv SMD.Selective yoj soldering tau tshwm sim, uas siv jetting, uas tso cai rau daim ntawv thov ntawm solder yuav tsum tau tswj thiab qhia tsuas yog rau cov chaw xaiv.Cov khoom siv los ntawm lub qhov tseem siv tau, thiab yoj soldering yeej yog cov txheej txheem ceev tshaj plaws kom sai sai soldering ntau ntawm cov khoom, thiab tej zaum yuav yog txoj kev zoo tshaj plaws, nyob ntawm koj tus qauv tsim.
Txawm hais tias daim ntawv thov ntawm lwm txoj kev soldering, xws li xaiv soldering, yog tsis tu ncua, yoj soldering tseem muaj qhov zoo uas ua rau nws muaj peev xwm xaiv tau rau PCB los ua ke.
