Vuam tshuab yog ib qho kev txawj ntse uas tseem ceeb heev rau kev tsim cov khoom siv hluav taws xob. Qee lub peev xwm, uas yog ib feem ntawm cov txheej txheem vuam ua tiav ntawm 10- tus cwj pwm hauv paus ntawm vuam - "ib qho kev sib tsoo, ob lub plating, peb qhov kev sim, plaub vuam, thiab tsib qhov kev soj ntsuam" - yog qhov tsim nyog rau kev siv phau ntawv soldering nrog hluav taws xob hlau.
1. Ib chais
Ua ntej vuam, qhov saum npoo ntawm cov khoom hlau yuav tsum tau muab ntxuav kom huv raws li qhia hauv daim duab 3. Tom qab ntawd, siv riam, txhuam hniav, roj, lossis cov xim pleev xim, koj txhuam tawm cov oxide txheej los ntawm qhov chaw vuam kom txog rau thaum cov hlau tshiab. yog nthuav tawm. Ua ntej soldering, lub rooj tsavxwm hauv tsev yuav tsum tau maj mam polished nrog cov ntawv xuab zeb zoo los yog daim ntawv ntub dej. Txawm hais tias "scraping" yog ib kauj ruam tseem ceeb los lav qhov zoo ntawm vuam, cov pib tshiab qee zaum hla nws. Nws yuav tsum raug pom tias qee cov khoom siv lead ua muaj nyiaj, kub, lossis tinned plating rau lawv. Tsis tas yuav txhuam nws yog tias tsis muaj oxidation lossis tev tawm.Koj tuaj yeem siv cov roj hmab ntxhib los tshem tawm cov av ntawm qhov chaw. Rau kev kos duab nrog cov nplaum loj loj, cov nplaum nplaum nplaum yog qhov kev xaiv zoo tshaj plaws. Tom qab tshem tawm cov txheej plating, nws yuav nyuaj rau cov phaj kub-plated siv lead ua triode tus pin leads, thiab lwm yam nrog tin. Txawm li cas los xij ntawm "scraping" yog siv, nco ntsoov tig cov pins tivthaiv tsis tu ncua kom huv si tag nrho cov ncig.
2. Ob lub plating
Lub Cheebtsam uas yuav tsum tau welded yuav tsum tau plated, raws li qhia nyob rau hauv daim duab 4. Nrog ib tug hluav taws xob soldering hlau, ib tug me me txheej ntawm tin yuav tsum tau muab tso rau kom tiv thaiv lub nto los ntawm re-oxidizing tom qab "scraping" welding qhov chaw ntawm lub tivthaiv pins, hlau taub hau, thiab lwm yam. Qhov no yuav ua rau kom cov khoom muaj peev xwm ua tau zoo. poj niam deev. Lub plated solder txheej yuav tsum nyias thiab homogeneous, yog li ntawd yuav tsum tsis txhob muaj ntau ntau tin ntawm lub soldering hlau taub thaum twg los tau.Siv tweezers los yog koob-qhov ntswg pliers rau clamp lub hauv paus ntawm cov hlau lead pins ntawm cov khoom xws li transistors thiab siv lead ua. diodes uas ntshai ntawm tshav kub thiaj li yuav pab tau thaum tshav kub kub dissipation ua ntej tin plating. Tining Cheebtsam yog cov txheej txheem tseem ceeb hauv kev siv tshuab vuam uas yuav tsum tau ua tib zoo kom tsis txhob muaj kev phom sij zais xws li vuam cuav thiab vuam cuav.
3. Peb qhov kev xeem.
Lub hom phiaj ntawm qhov kev xeem yog los tshuaj xyuas cov tinned Cheebtsam kom pom tias lawv puas yog lap welded (luv circuited), scorched, los yog lwm yam puas los ntawm qhov kub ntawm cov hluav taws xob soldering hlau. Siv lub multimeter, nws yog ib qho tseem ceeb rau kev ntsuam xyuas qhov kev cia siab ntawm capacitors, transistors, integrated circuits, thiab lwm yam khoom; cov uas pom tias muaj kev puas tsuaj los yog puas yuav tsum tsis txhob rov siv dua.
3. Peb vuam
Thaum tsim nyog, soldering entails txuas cov khoom mus rau lub rooj tsav xwm luam tawm los yog qhov chaw npaj tom qab lawv tau dhau qhov kev xeem "test". Nco ntsoov paub txog qhov kub thiab txias lub sij hawm ntawm cov hluav taws xob soldering hlau thaum soldering. Lub tin saum npoo yuav muaj burr-zoo li tails, yuav tsis du, los yog txawm zoo li tofu slag yog tias qhov kub thiab txias tsis dhau thiab lub sij hawm faib luv luv. Qhov tsis muaj flux tuaj yeem raug liam. Tseem muaj qee qhov flux ntawm cov solder thiab hlau tom qab tag nrho evaporation. Tom qab txias, lub flux (rosin) uas tuav lub solder thiab hlau nto ua ke yog adherent thiab yog yooj yim sib cais.Qhov no yog hu ua fake soldering.
5. Kos tsib.
Kev tshuaj xyuas lub hom phiaj yog txhawm rau ntsuas lub voj voog qhov vuam zoo. Nyob rau hauv cov kev sib txuas ntawm solder, yuav tsum tsis txhob muaj cov vuam cuav, vuam virtual, qhib circuits, los yog luv luv Circuit Court, tshwj xeeb tshaj yog yog hais tias tus pins ntawm polar Cheebtsam xws li electrolytic capacitors thiab transistors raug welded. Cov xim thiab gloss ntawm qhov sib koom ua ke, qhov sib txawv ntawm qhov sib txawv, thiab qhov ntau ntawm cov khoom siv tuaj yeem siv los ntsuas qhov zoo ntawm vuam. Nrog zoo soldering, lub solder kev twb kev txuas muaj ib tug tshwj xeeb dazzling dawb ci uas yog ib qho yooj yim kom paub txog ib nrais muag. Ntawm qhov tod tes, nrog tsis zoo soldering, xim thiab luster ntawm lub solder yog stained, los yog saum npoo yog uneven.
