Qhov kub hloov pauv ntawm cov hlau soldering thiab cov sib koom ua ke
4.1 Qhov zoo tshaj plaws vuam tej yam kev mob
Lub xeev vuam zoo tshaj plaws yog tias lub zog hluav taws xob ntawm cov hluav taws xob soldering hlau yog tas li thiab tsis hloov vim qhov kev hloov pauv hauv lub ntiaj teb sab nraud. Cov txheej txheem vuam tuaj yeem ua tiav los ntawm kev tswj lub sijhawm vuam raws li lub peev xwm kub ntawm cov khoom yuav tsum tau welded.
Piv txwv tias 63Sn / 37Pb solder hlau raug xaiv, nws cov ntsiab lus melting yog 183 degree, qhov zoo tshaj plaws vuam kub yog 223 degree, thiab vuam ua tiav tom qab 2 s txog 5 s, qhov zoo tshaj plaws tshav kub zog hloov pauv nkhaus ntawm cov vuam sib koom ua ke thaum vuam. txheej txheem.
Thaum qhov kub ntawm cov hlau soldering tas li ntawm 223 degree, lub sij hawm yuav tsum tau rau qhov kub ntawm cov khoom yuav tsum tau soldered kom sawv los ntawm qhov kub thiab txias ntawm 25 degree mus rau 223 degree yog hais txog lub tshav kub ntawm cov khoom yuav tsum tau soldered. Thaum lub peev xwm kub ntawm cov khoom yuav tsum tau welded yog me me, qhov kub thiab txias nce sai heev. Thaum tshav kub muaj peev xwm ntawm cov khoom yuav tsum tau welded yog loj, qhov kub nce tus nqi qeeb. Yog li ntawd, hauv kev ua haujlwm tiag tiag, raws li qhov loj ntawm cov pob qij txha, qhov sib txawv ntawm cov lus qhia ntawm cov hlau yuav tsum raug xaiv thiab qhov kub ntawm cov hlau yuav tsum tau hloov kho kom tau txais cov txiaj ntsig zoo.
4. 2 Cov ntaub ntawv ntawm cov hlau soldering
Muaj kwv yees li peb hom hluav taws xob soldering hlau niaj hnub no:
(1) Ordinary electric soldering irons cia siab rau qhov loj ntawm qhov kev tiv thaiv kom tau txais qhov ntsuas kub tsis tu ncua, tsis muaj kev tswj hwm qhov kub thiab txias, thiab qhov ntsuas kub tsis zoo;
(2) Qhov kub thiab txias tsis tu ncua hluav taws xob soldering hlau, qhov tso zis kub yog tswj los ntawm qhov kub thiab txias, qhov kub thiab txias stability yog qhov zoo, qhov tsim tau ruaj khov thiab tsis tuaj yeem hloov kho;
(3) Qhov kub thiab txias-kho tau hluav taws xob soldering hlau muaj cov yam ntxwv ntawm qhov kub thiab txias hluav taws xob soldering hlau, thiab tuaj yeem kho qhov tso zis kub raws li qhov xav tau. Nyob rau tib lub sijhawm, nws tuaj yeem kuaj xyuas tias qhov ntsuas kub tau ua raws li qhov tseeb ntawm qhov ntsuas kub ntawm lub taub hau. Txawm li cas los xij, hauv kev siv tiag tiag, tsis muaj ib qho ntawm cov khoom siv hluav taws xob uas twb muaj lawm tuaj yeem ncav cuag qhov kub thiab txias. Feem ntau, qhov zoo ntawm soldering yog ua kom ntseeg tau los ntawm kev ua kom lub zog los yog kub ntawm cov hluav taws xob soldering hlau, uas feem ntau hu ua qhov kub ntawm qhov hluav taws xob soldering hlau rau vuam. Piv txwv li: xaiv 63Sn / 37Pb solder hlau, nws cov ntsiab lus melting yog 183 degree, qhov zoo tshaj plaws vuam kub yog 223 degree, nce qhov kub ntawm cov hluav taws xob soldering hlau kom siab tshaj qhov zoo tshaj vuam kub rau vuam, xws li 260 degree ,
280 degree thiab 320 degree thiab lwm yam.
