General siv 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 los 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. Lub 20W sab hauv cua sov hluav taws xob soldering hlau yog txaus rau cov transistor dav dav thiab cov khoom siv hluav taws xob sib txuas ua ke. Yog hais tias lub hwj chim siab dhau lawm, nws yog ib qho yooj yim rau hlawv tawm cov khoom, vim hais tias qhov sib txuas kub ntawm diodes thiab triodes yuav hlawv tawm yog tias qhov kub ntawm qhov sib txuas siab tshaj 200 degree. 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 cov 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 tsavxwm. Tsis tas li ntawd, lub tshuab nqus tsev nqus tau zoo heev 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 tuaj yeem 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 tsavxwm. 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.
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.
Vuam zoo ----- Thaum vuam, nws yog ib qho tsim nyog los xyuas kom meej tias txhua qhov sib txuas yog ruaj khov thiab sib cuag zoo. Txhawm rau kom ntseeg tau qhov zoo ntawm vuam, nws cov yam ntxwv zoo ib yam yog qhov ci tin me ntsis, du thiab pos, thiab cov ntsiab lus tin nruab nrab. Lub tin thiab cov khoom yuav tsum tau welded yog ruaj khov, thiab yuav tsum tsis txhob muaj kev vuam cuav lossis cuav vuam. False soldering txhais tau hais tias tsuas yog ib qho me me ntawm cov tin yog welded ntawm qhov sib koom ua ke, ua rau muaj kev sib cuag tsis zoo thiab cuam tshuam rau thiab tawm. False welding txhais tau hais tias nws zoo li welded rau saum npoo, tab sis nws tsis yog welded. Qee zaum cov hlau lead tuaj yeem rub tawm los ntawm kev sib koom ua ke los ntawm kev rub tawm ntawm tes. Thaum soldering lub Circuit Court board, nco ntsoov tswj lub sij hawm. Yog tias nws ntev dhau lawm, lub rooj tsav xwm Circuit Court yuav raug hlawv, lossis daim ntawv tooj liab yuav poob. Thaum tshem cov khoom los ntawm lub rooj tsav xwm hauv Circuit Court, lo lub hau ntawm cov hluav taws xob soldering hlau rau ntawm qhov sib koom ua ke, thiab rub tawm cov khoom tom qab cov tin ntawm cov khoom sib koom ua ke.
Yuav hloov cov khoom siv li cas ------ Qhov tseeb, hloov cov khoom yuav tsis yooj yim dua. Nws tuaj yeem ua tau yooj yim nrog lub tshuab nqus tsev, thiab tag nrho cov solder ntawm cov khoom siv pins yuav raug nqus tawm. Nov yog qhov ua kom yuam kev me me rau koj. Tam sim no Circuit Court Feem ntau ntawm cov laug cam yog finely crafted, lub solder yog tsis tshua muaj siv, thiab nws yog ib qho nyuaj rau yaj, yog li nws yooj yim dua rau peb ntxiv ib co solder rau cov pins thiab ces siv lub solder absorber. Lwm txoj kev yog raws li tau hais los saum toj no, ncaj qha siv cov hluav taws xob soldering hlau kom yaj tawm ntawm lub solder, tab sis muaj ntau yam txaus ntshai nyob rau hauv txoj kev no, tsis tsuas yog yuav tsum tau ceev faj tias cov pob qij txha tsis yog melted kiag li, tab sis kuj yuav tsum ntshai. hlawv tawm cov khoom yog tias lawv nyob rau hauv kev sib cuag ntev heev. Txoj hauv kev yog siv cov tweezers los tuav cov khoom thiab rub tawm thaum kub siab. Thaum qhov kub nce mus txog, cov khoom yuav raug rub tawm, tab sis nco ntsoov tsis txhob siv lub zog ntau dhau, txwv tsis pub nws yuav muaj teeb meem yog tias tus pin tawg hauv lub solder. Ntawm chav kawm, rau kev nyab xeeb, nws yog qhov zoo dua los siv ob txoj hauv kev ua ke, vim tias qee zaum lub tshuab nqus tsev yog qhov nyuaj rau kev nqus huv vim tias cov khoom siv lub qhov (socket) me dhau. Tshav kub ntawm cov hlau soldering thiab tshem tawm nws. Vuam yeej tsis yog qhov txaus ntshai. Tej zaum nws yuav nyuaj rau cov neeg pib xyaum ua thawj zaug, tab sis nws yuav ua tau zoo dua yog tias koj xyaum ntau dua. Hauv luv luv, rau cov neeg txhawb siab uas nyiam kev sib koom tes, tsuav yog koj xyaum ntau, nws yuav yog lub sijhawm ua ntej koj paub qhov kev ua kom yuam kev.
