Cov lus qhia rau kev siv yooj yim ntawm hluav taws xob soldering hlau
Cov hluav taws xob soldering hlau yog cov cuab yeej siv feem ntau hauv kev siv hluav taws xob vuam. Nws txoj haujlwm yog hloov hluav taws xob rau hauv hluav taws xob hluav taws xob rau hluav taws xob thiab vuam qhov taw tes. Ib feem loj ntawm nws txoj kev vam meej nyob ntawm seb nws tswj tau zoo npaum li cas. Yog li ntawd, los ntawm ib qho kev pom, hluav taws xob soldering hlau Kev siv nws nyob ntawm kev nkag siab ntawm cov txheej txheem.
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. Lub 20W sab hauv cua sov hom hluav taws xob soldering hlau yog txaus rau cov transistors thiab cov khoom siv hluav taws xob sib xyaw ua ke. Yog tias lub hwj chim siab dhau lawm, nws yog qhov yooj yim los hlawv cov khoom, vim tias qhov kub thiab txias ntawm diodes thiab triodes yuav hlawv yog tias qhov kub siab tshaj 200 degrees. Txawm li cas los xij, hauv kev tsim cov khoom siv hluav taws xob feem ntau yog siv rau kev sib txuas, lub zog ntawm cov hluav taws xob soldering hlau yuav tsum siab dua, thiab lub zog ntawm cov hluav taws xob soldering hlau tuaj yeem xaiv los ntawm 35W-45W, lossis siab dua.
Nws yog ib nqi sau cia hais tias thaum welding lub Circuit Court, lub sij hawm yuav tsum tsis txhob ntev los yog luv heev. Yog hais tias lub sij hawm ntev heev, nws yuav yooj yim puas, tab sis yog lub sij hawm luv luv, lub solder yuav tsis muaj peev xwm yaj tag, ua rau cov pob qij txha tsis sib xws thiab cov khoom cuav. Rau lub sijhawm tsim nyog tshaj plaws yuav tsum ua kom tiav hauv 1.5s ~ 4s.
Solder yog cov hlau fusible, thiab feem ntau siv yog feem ntau solder hlau. Lub luag haujlwm ntawm solder yog los txuas cov khoom sib txuas nrog cov ntsiab lus sib txuas ntawm lub rooj tsav xwm luam tawm, thiab kev xaiv ntawm solder muaj kev cuam tshuam zoo rau cov khoom zoo. Tam sim no qhov feem ntau siv yog rosin solder hlau, tab sis nws kuj yog tshwj xeeb tshaj yog hais txog cov subdivision. Ntawm lawv, cov nyiaj solder hlau uas yog tiag tiag tsis tov nrog dej yog ntawm chav kawm thawj cov khoom.
Nws tseem tsim nyog hais txog lub tshuab nqus tsev, uas yog qhov zoo rau cov novices. Nws yog ib qho yooj yim kom tau solder nyob txhua qhov chaw thaum siv cov hlau soldering thawj zaug. Lub tshuab nqus tsev tuaj yeem pab koj pov tseg cov khoom siv ntau dhau ntawm lub rooj tsav xwm hauv Circuit Court. Tsis tas li ntawd, lub tshuab nqus tsev nqus tau zoo heev thaum tshem tawm cov khoom siv ntau tus pin sib xyaw ua ke. Nws tuaj yeem nqus tau tag nrho cov pob qij txha, tab sis nws yog qhov tsis tsim nyog rau cov neeg uas txawj siv cov hlau soldering. Nws tuaj yeem hloov kho nws txoj haujlwm nrog cov hlau soldering. Cov khoom siv tau yooj yim tshem tawm los ntawm melting tawm cov pob qij txha.
Ua ntej soldering, kev kho mob ua ntej yuav tsum tau ua ntawm cov khoom siv pins lossis cov khoom siv ntawm lub rooj sib tham. Tshem tawm cov oxide txheej ntawm qhov sib txuas - ib rab riam tuaj yeem ua los ntawm cov saw hlau tawg kom khawb tawm cov oxide txheej ntawm cov hlau lead kom nthuav tawm cov hlau ci ntawm cov hlau lead. Lub rooj tsav xwm luam tawm tuaj yeem polished nrog cov ntaub nplaum zoo, thiab tom qab ntawd coated nrog ib txheej ntawm rosin cawv tov. Cheebtsam tinning - tinning ntawm scraped leads. Tom qab dipping cov hlau lead hauv cov tshuaj rosin cawv, nias lub hau ntawm cov hlau kub kub nrog cov tin ntawm cov hlau lead thiab tig cov hlau lead. Cov txhuas tuaj yeem sib npaug plated nrog ib txheej nyias ntawm tin. Ua ntej cov hlau yog welded, lub rwb thaiv tsev sheath yuav tsum tau tev tawm, thiab tom qab ntawd cov saum toj no ob txoj kev kho yuav tsum tau ua ua ntej formal welding. Nyob rau hauv cov ntaub ntawv ntawm multi-strand nyob ntawm tej, lawv yuav tsum tau twisted ua ke tom qab polishing, thiab ces tinned.
