Yuav ua li cas solder Cheebtsam nrog ib tug soldering hlau:
Pre-weld kev kho mob
1. Tshem tawm cov oxide txheej ntawm qhov vuam
Ib rab riam tuaj yeem ua los ntawm cov hniav tawg. Tshem tawm cov oxide txheej ntawm cov hlau ua kom nthuav tawm cov hlau nplaum 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.
2. Cov khoom siv tin plating
Tin on 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 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.
2. Vuam zoo
Thaum welding, nws yog ib qho tsim nyog los xyuas kom meej tias txhua qhov sib koom ua ke yog ruaj khov thiab sib cuag zoo. Los xyuas kom meej qhov zoo ntawm vuam.
Lub tin taw tes yuav tsum ci, du tsis muaj burrs, thiab tus nqi ntawm cov tin yuav tsum yog nruab nrab. Tin thiab solder yog nrees fused. Yuav tsum tsis muaj kev vuam cuav thiab vuam cuav.
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.
