Soldering chaw nres tsheb tswv yim - yuav ua li cas yog hais tias muaj ib tug luv luv Circuit Court nyob rau hauv txhuas solder paste soldering?
Ib, yog vim li cas rau luv luv Circuit Court nyob rau hauv cov hlau lead solder paste soldering:
Thawj qhov uas yuav tsum tau xav txog yog seb puas muaj cov seem seem ntawm PCB, yog li ua ntej txiav txim siab seb puas muaj cov dej xau thaum siv cov khoom siv nrog cov hmoov txhuas muab tshuaj.
Tom qab lub rooj tsavxwm PCB raug laum thiab soldered, seb puas yuav ntxuav nws, yog tias muaj dej xau, nws yuav tshwm sim los ntawm ntau yam.
1. Yog hais tias lub rooj tsavxwm PCB puas lawm, nws twb tau luv luv. Hais txog qhov no, qhov kev xeem ua ntej tuaj yeem ua tiav ua ntej siv lub rooj tsavxwm PCB.
2. Nws tsis huv. Tsis tas li ntawd, txawm hais tias tus neeg saib xyuas siv yuav ua rau corrosion los yog muaj residues kuj yuav tsum tau qhia meej.
Qhov kev ncua deb ntawm cov pob qij txha ntawm lub PCB pawg thawj coj saib yuav tsum tsis txhob nyob ze, thiab lub zog zaus ntawm cov pob qij txha kuj yog ib qho tseem ceeb uas yuav tsum tau txiav txim siab txog kev xau.
Thaum cov pob qij txha raug kaw los yog lub zog ntau zaus ntawm cov pob qij txha yog siab heev, txhawm rau kom tau txais cov txiaj ntsig zoo tshaj plaws, nws raug nquahu kom siv cov hlau tsis muaj hlau lead lossis rosin core solder hlau, thiab ntxuav nws tom qab soldering.
Cov dej xau tuaj yeem cuam tshuam nrog kev rwb thaiv tsev ntawm cov khoom siv nws tus kheej. Qhov me me ntawm rwb thaiv tsev tsis kam ntawm cov khoom siv, qhov ntau dua qhov muaj peev xwm ntawm to. Lub rwb thaiv tsev tsis kam ntawm ntau hom txhuas solder paste sib txawv nrog tus neeg sawv cev ua haujlwm.
Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv cov khoom zoo, nquag siv lead ua solder paste. Jiajinyuan leaded solder paste tso cai rau koj siv nws nrog kev ntseeg siab.
Ob, leaded solder paste nce kev ua tau zoo tsom xam
Nyob rau hauv lub ntsej muag ntawm leaded solder paste, soldering yog ib qho ntawm cov qauv los ntsuas nws qhov zoo. Cov nyhuv soldering zoo tuaj yeem ua rau kev ua haujlwm zoo thiab cov tsos tom qab soldering zoo heev, thaum cov nyhuv tsis zoo yuav ua rau cov txiaj ntsig tsis zoo. Yog li ntawd, rau cov hmoov txhuas txhuas, cov tin nce toj cov nyhuv yog qhov tseem ceeb los ntsuas nws qhov zoo.
Txawm hais tias cov tshuaj txhuam hniav nce lub tin yog qhov zoo lossis tsis zoo, peb tuaj yeem txheeb xyuas nws los ntawm cov ntsiab lus hauv qab no:
1. Lub tshuab luam ntawv zoo ntawm cov khoom siv hluav taws xob uas tsis tau ua tiav los ntawm lub tshuab hluav taws xob rau lub sijhawm ntev yuav raug cuam tshuam, los yog qhov zoo ntawm cov tshuaj nplaum tau raug degraded vim lub sij hawm cia ntev, los yog tej zaum yuav tshwm sim los ntawm qhov tsis txaus. tin leakage vim qhov qhib nyias ntawm stencil.
2. Txheeb xyuas qhov kub thiab txias. Yog hais tias qhov kub thiab txias ncav cuag qhov siab tshaj plaws, cov khoom yog oxidized.
3. Los ntawm ob qho tib si ntawm cov khoom siv tsis zoo, qhov ua tau yog oxidation lossis noo noo, thiab nws tseem yuav tsum tau xyuas seb qhov kub ntawm lub cub tawg puas tau hloov.
4. Qhov laj thawj tseem ceeb yog tias lub cuab yeej yog oxidized, thiab qhov thib ob yog qhov kev ua haujlwm flux raug txo vim yog cov khoom siv solder tas sij hawm, yog li qhov chaw uas cov khoom siv tau zoo yog tam sim no soldered. Sim ib lub kaus poom tshiab uas tsis tas yuav siv tshuaj txhuam ua ntej.
5. Ua ntej xyuas seb cov khoom siv raw yog oxidized, los yog vim tias qhov kub thiab lub sijhawm melting tsis txaus.
