Nrog rau txoj kev loj hlob sai ntawm cov ntaub ntawv siv hluav taws xob niaj hnub no, kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob ntim cov ntaub ntawv tau tshwm sim nyob rau hauv qhov kawg, thiab cov ntim ntim tau nce siab dua, uas tau txhawb nqa kev loj hlob ntawm cov khoom siv hluav taws xob hauv kev coj ua ntau yam, kev ua haujlwm siab, kev ntseeg siab thiab tus nqi qis. Txog niaj hnub no, kev siv thev naus laus zis los ntawm qhov (THT) thiab nto mount thev naus laus zis (SMT) muaj ntau hauv kev tsim khoom siv hluav taws xob. Lawv tau siv dav hauv cov txheej txheem PCBA thiab muaj lawv tus kheej zoo lossis kev ua haujlwm.
Raws li cov khoom siv hluav taws xob sib txuas ua kom ntom ntom, qee qhov los ntawm lub qhov ntxig tsis tuaj yeem raug soldered siv ib txwm yoj soldering. Qhov tshwm sim ntawm kev xaiv laser soldering tshuab zoo nkaus li yog ib daim ntawv tshwj xeeb ntawm kev xaiv cov cuab yeej siv cuab yeej tsim los ua kom tau raws li txoj kev loj hlob ntawm kev sib txuas ntawm qhov sib txuas. Nws cov txheej txheem tuaj yeem siv los hloov cov yoj vuam, thiab tuaj yeem siv tus kheej Cov txheej txheem ntawm cov pob qij txha tau ua kom zoo kom ua tiav qhov zoo tshaj plaws vuam zoo.
Cov evolution ntawm cov txheej txheem soldering rau cov khoom ntawm lub qhov
Nyob rau hauv txoj kev loj hlob ntawm niaj hnub hluav taws xob vuam tshuab, nws tau ntsib ob lub keeb kwm kev hloov pauv:
Thawj lub sij hawm yog qhov kev hloov ntawm los ntawm qhov-lub qhov soldering tshuab rau nto mount soldering tshuab; lub sij hawm thib ob yog qhov kev hloov pauv uas peb tau ntsib los ntawm cov hlau lead soldering technology mus rau cov hlau lead-free soldering technology.
Lub evolution ntawm vuam tshuab ncaj qha coj ob yam:
Ua ntej, muaj tsawg dua thiab tsawg dua los ntawm lub qhov uas yuav tsum tau welded ntawm Circuit Court boards; Thib ob, cov khoom siv los ntawm lub qhov (tshwj xeeb tshaj yog qhov muaj peev xwm loj los yog cov khoom zoo-pitch) tau dhau los ua qhov nyuaj rau vuam, tshwj xeeb tshaj yog rau cov khoom tsis muaj hlau lead thiab cov khoom zoo. Cov khoom siv nrog kev ntseeg siab.
Cia peb saib cov kev cov nyom tshiab uas ntsib lub ntiaj teb kev lag luam hluav taws xob sib dhos:
Kev sib tw thoob ntiaj teb yuam cov tuam txhab coj cov khoom lag luam hauv lub sijhawm luv dua kom tau raws li cov kev hloov pauv ntawm cov neeg siv khoom; hloov raws caij nyoog nyob rau hauv cov khoom xav tau yuav tsum tau saj zawg zog manufacturing tswv yim; kev sib tw thoob ntiaj teb yuam cov tuam txhab tsim khoom los txhim kho qhov zoo ntawm qhov chaw ntawm Txo cov nqi khiav lag luam; txhuas-dawb ntau lawm yog cov qauv dav dav. Cov kev cov nyom saum toj no yog ib txwm muaj kev cuam tshuam los ntawm kev xaiv cov kev tsim khoom thiab cov khoom siv, uas tseem yog qhov laj thawj tseem ceeb vim li cas xaiv laser soldering tau tsim sai dua li lwm txoj kev vuam hauv xyoo tas los no; tau kawg, qhov tuaj txog ntawm lub sijhawm tsis muaj cov hmoov txhuas kuj txhawb nqa nws txoj kev loj hlob lwm qhov tseem ceeb.
Laser soldering tshuab yog ib qho ntawm cov cuab yeej siv hauv kev tsim ntau yam khoom siv hluav taws xob. Cov txheej txheem no suav nrog cov khoom siv hluav taws xob tshwj xeeb rau cov ntawv luam tawm hauv Circuit Court boards yam tsis muaj kev cuam tshuam rau lwm qhov chaw ntawm lub rooj tsav xwm Circuit Court, feem ntau cuam tshuam nrog lub rooj tsav xwm Circuit Court. Nws yog feem ntau ua tiav los ntawm peb txheej txheem ntawm ntub dej, diffusion thiab metallurgy. Lub solder maj mam diffuses mus rau lub ncoo hlau ntawm lub rooj tsavxwm Circuit Court, tsim ib tug hlau txheej ntawm kev sib cuag nto ntawm lub solder thiab lub ncoo hlau, thiaj li hais tias ob yog ruaj khov. Los ntawm cov khoom siv programming, xaiv vuam ua tiav rau txhua qhov sib koom ua ke.
Qhov zoo ntawm laser soldering tshuab hauv kev tsim hluav taws xob
1. Kev ua haujlwm tsis sib cuag, tsis muaj kev ntxhov siab, tsis muaj kuab paug;
2. Laser soldering yog zoo thiab sib xws, nrog tag nrho cov pob qij txha thiab tsis muaj tin hlaws dai;
3. Laser soldering yuav pab tau automation;
4. Cov cuab yeej siv hluav taws xob tsawg, yog kev txuag hluav taws xob thiab ib puag ncig tus phooj ywg, muaj tus nqi qis thiab tus nqi tu;
5. Tau tshaj cov ntaub ntawv loj dua thiab cov ntaub ntawv precision, qhov me me ntawm lub ncoo loj yog mus txog 60um, ua kom precision vuam yooj yim kom ua tiav;
6. Cov txheej txheem yog yooj yim thiab tuaj yeem ua tiav hauv ib qho kev lag luam vuam. Tsis tas yuav tshuaj tsuag / luam tawm flux thiab cov txheej txheem tu tom ntej.
