Soldering kev nrog 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 hluav taws xob mus rau hauv lub zog hluav taws xob kom sov 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. Feem ntau, 20W sab hauv cua sov hluav taws xob soldering hlau yog txaus rau vuam ntawm transistors thiab kev sib txuas hauv hluav taws xob cov khoom siv hluav taws xob. 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 lub Circuit Court yog soldered, lub sij hawm yuav tsum tsis txhob ntev heev los yog luv luv. Yog hais tias lub sij hawm ntev dhau lawm, nws yuav yooj yim puas, thiab yog tias lub sij hawm luv luv, lub solder yuav tsis muaj peev xwm yaj tag nrho, 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 cov solder muaj kev cuam tshuam zoo rau cov khoom zoo. Cov feem ntau siv yog rosin solder xov hlau, tab sis cov subdivisions kuj yog heev tshwj xeeb. Ntawm lawv, cov xov hlau nyiaj hlau uas tsis sib xyaw nrog dej yog cov qib siab tshaj plaws.
Nws tseem tsim nyog hais txog cov khoom siv hluav taws xob, uas yog qhov ua tau 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 solder absorber tuaj yeem pab koj tshem tawm ntau dhau ntawm cov khoom siv hluav taws xob. Tsis tas li ntawd, tin absorber muaj txiaj ntsig zoo thaum tshem tawm cov khoom siv sib txuas nrog ntau tus pin. 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 ua tau ua ntej formal welding. Nyob rau hauv cov ntaub ntawv ntawm multi-strand xov hlau, lawv yuav tsum tau twisted ua ke tom qab polishing, thiab ces tinned.
Tom qab kev kho mob ua ntej vuam ua tiav, vuam tuaj yeem ua tiav:
(1) Tuav hluav taws xob soldering hlau ntawm sab tes xis. Siv rab koob-qhov ntswg pliers lossis tweezers nrog koj sab tes laug los tuav cov khoom lossis cov xov hlau. Ua ntej soldering, hluav taws xob soldering hlau yuav tsum tau preheated tag nrho. Tin yuav tsum tau noj rau ntawm cov hniav saum npoo ntawm lub taub hau ntawm lub taub hau, uas yog, ib qho nyiaj ntawm cov solder yuav tsum tau coj tuaj.
(2) Muab cov hniav ntawm cov hlau taub hau rau ntawm qhov sib koom ua ke. Lub tshuab hluav taws xob hluav taws xob yog nyob ntawm kaum ntawm 60 degree rau lub dav hlau kab rov tav. Txhawm rau kom yooj yim rau kev khiav ntawm molten tin los ntawm qhov kawg ntawm cov hlau soldering mus rau qhov sib koom ua ke. Lub sij hawm lub taub hau hlau nyob ntawm qhov sib koom ua ke yog tswj tsis pub dhau 2 mus rau 3 vib nas this.
(3) Nqa lub taub hau ntawm cov hlau soldering. Sab laug tes tseem tuav cov khoom. Sab laug tes tsuas yog tso tawm tom qab lub tin ntawm lub solder sib koom yog txias thiab solidified.
(4) Tig cov hlau lead nrog tweezers kom paub meej tias nws tsis xoob, thiab tom qab ntawd siv cov pliers txiav tawm cov hlau lead ntau dhau.
