Yuav ua li cas siv hluav taws xob soldering hlau hauv hluav taws xob xyaum
Raws li kev ntim khoom ntawm cov khoom siv hluav taws xob tau hloov kho sai thiab nrawm dua, cov khoom ntawm lub rooj tsav xwm hauv Circuit Court tau tsawg dua thiab ntom ntom, cov pins tau thinner, thiab lub rooj tsav xwm hauv Circuit Court tau me dua thiab me dua. Ntxiv mus, ib tug loj tus naj npawb ntawm nto mount Cheebtsam, flip chips thiab lwm yam Cheebtsam yog siv nyob rau hauv lub Circuit Court board, uas tsis muaj qhov tshwj xeeb qhia tau hais tias kev lag luam hluav taws xob tau tsim los ntawm miniaturization thiab miniaturization, thiab qhov nyuaj ntawm phau ntawv soldering kuj tau nce raws li. Kev ceev faj yuav ua rau cov khoom puas tsuaj, lossis ua rau cov vuam tsis zoo, yog li cov neeg ua haujlwm yuav tsum muaj kev nkag siab txog cov txheej txheem vuam, txheej txheem vuam, txoj kev vuam, kev ntsuam xyuas vuam zoo, thiab lub hauv paus hauv hluav taws xob.
1 soldering cuab yeej
Lub tshuab hluav taws xob soldering hlau yog cov cuab yeej siv feem ntau hauv kev vuam, thiab ib feem loj ntawm seb qhov vuam puas zoo nyob ntawm seb nws zoo npaum li cas. Feem ntau hais lus, qhov loj dua lub zog ntawm cov hluav taws xob soldering hlau, qhov kub ntau dua, thiab qhov kub ntawm cov hlau soldering ntau dua. Piv txwv li, peb siv 20W sab hauv cua sov hom (30 ~ 40W sab nraud cua sov hom) hluav taws xob soldering hlau rau kho vajtse transformation. Yog tias lub zog siab dhau lawm, nws yooj yim rau hlawv cov khoom. Feem ntau, qhov sib txuas kub ntawm diodes thiab triodes yuav puas yog tias qhov kub siab tshaj 200 degree.
Muaj ob hom hluav taws xob soldering hlau uas nquag siv tam sim no: hom cua sov sab nraud thiab hom cua sov sab hauv. Cov cua sov sab hauv hom hluav taws xob soldering hlau muaj kev ua haujlwm siab thermal thiab ceev cua kub ceev. Lub hwj chim ntawm sab nraud kub soldering hlau yog siab dua, thiab txoj kev siv yog tib yam, tab sis muaj ntau yam accessories rau lub sab hauv kub soldering hlau nyob rau hauv lub lag luam, yog li nws yog pom zoo kom siv lub internal tshav kub soldering hlau.
Ib qho yooj yim hluav taws xob soldering hlau yuav tsum tau coated nrog ib txheej ntawm solder ntawm lub ntsis ntawm cov hlau soldering ua ntej siv. Txoj kev tshwj xeeb yog: ua ntej xa cov taub ntawm cov hlau nplaum rau hauv cov duab uas xav tau, tom qab ntawd txuas cov khoom siv hluav taws xob, thaum qhov kub ntawm qhov taub ntawm cov hlau soldering nce mus rau qhov chaw uas cov tin tuaj yeem yaj tau, thov cov rosin ntawm lub taub. ntawm cov hlau soldering, thiab ces thov ib txheej ntawm solder kom txog rau thaum lub ntug ntawm lub ntsis ntawm lub soldering hlau Nws yuav siv tau los ntawm dai ib txheej ntawm tin rau ntawm lub ntsej muag.
2 Vuam txoj kev
Muaj ob yam tseem ceeb ntawm cov khoom nyob rau tam sim no Circuit Court boards, ib tug yog nyob rau hauv-line pin Cheebtsam, thiab lwm yam yog thaj Cheebtsam. Cov hauv qab no yuav tham tshwj xeeb txog txoj kev vuam ntawm txhua hom kev tivthaiv raws li ob hom ntawm cov khoom no.
3 Soldering lub sij hawm thiab qhov kub thiab txias
1) Qhov ntsuas kub yog txiav txim siab los ntawm kev siv tiag tiag. Nws yog qhov tsim nyog tshaj plaws rau solder point rau 1 ~ 4 vib nas this, thiab qhov siab tshaj plaws yog tsis ntau tshaj 8 vib nas this. Feem ntau saib qhov ntxeev ntawm cov hlau soldering. Thaum nws hloov ntshav, qhov kub thiab txias yog siab dhau.
2) Feem ntau, rau cov khoom siv hluav taws xob hauv-kab, teeb tsa qhov ntsuas kub ntawm lub taub hau rau (350 ~ 370 degrees); rau saum npoo mount cov ntaub ntawv (SMT), teem lub sij hawm kub ntawm lub soldering hlau taub rau (330 ~ 350 degrees), feem ntau lub melting point ntawm solder ntxiv 100 degrees.
3) Rau cov ntaub ntawv tshwj xeeb, qhov kub ntawm cov hlau soldering yuav tsum tau teem tshwj xeeb. LCD connectors, thiab lwm yam yuav tsum tau siv nyiaj-muaj tin xov hlau, thiab qhov kub thiab txias yog feem ntau ntawm 290 degrees thiab 310 degrees.
4) Solder loj tiv thaiv taw, qhov kub yuav tsum tsis txhob siab tshaj 380 degrees, tab sis koj tuaj yeem ua kom lub zog ntawm cov hlau soldering.
Tus nqi.
