Cov cuab yeej siv rau phau ntawv soldering ntawm SMD Cheebtsam
1. Hluav taws xob soldering hlau
Tes soldering Cheebtsam, qhov no yog qhov tseem ceeb. Ntawm no, peb pom zoo kom ib tug nrog ib tug sharper ntsis, vim hais tias thaum soldering ib tug nti nrog ntom pins, nws muaj peev xwm raug thiab yooj yim solder ib los yog ob peb pins.
2. Hlau hlau
Ib tug zoo solder hlau kuj tseem ceeb heev rau SMD vuam. Yog tias muaj kev tso cai, siv cov hlau nyias nyias raws li qhov ua tau thaum soldering SMD Cheebtsam, kom nws yooj yim los tswj tus nqi ntawm cov tin, yog li tsis tas yuav nkim cov teeb meem ntawm soldering thiab absorbing tin.
3. Tweezers
Lub luag haujlwm tseem ceeb ntawm tweezers yog kom yooj yim khaws thiab tso cov khoom SMD. Piv txwv li, thaum soldering SMD resistors, tweezers tuaj yeem siv los clamp cov resistors thiab muab tso rau ntawm lub rooj tsav xwm Circuit Court rau vuam. Tweezers yuav tsum tau taw tes thiab tiaj tus kom yooj yim tuav cov khoom. Tsis tas li ntawd, rau qee cov chips uas yuav tsum tau muaj kev tiv thaiv los ntawm hluav taws xob zoo li qub, yuav tsum muaj cov tweezers anti-static.
4. Tin suction daim kab xev
Thaum soldering SMD Cheebtsam, nws yog ib qho yooj yim kom muaj ntau tin.
Tshwj xeeb tshaj yog thaum soldering ntom multi-pin SMD chips, nws yog ib qho yooj yim los ua ob tus pins uas nyob ib sab los yog ntau tus pins ntawm cov nti kom luv luv los ntawm solder. Lub sijhawm no, cov khoom siv tin suction yog tsis muaj txiaj ntsig, thiab cov hlua khi hlua khi yuav tsum tau siv rau lub sijhawm no.
Solder strips tuaj yeem yuav los ntawm cov chaw muag khoom muag. Yog tias koj tsis muaj lawv, koj tuaj yeem hloov lawv nrog tooj liab hauv cov xov hlau, uas yuav piav qhia tom qab.
5. Rosin
Rosin yog cov feem ntau siv flux nyob rau hauv soldering, vim hais tias nws muaj peev xwm precipitate oxides nyob rau hauv lub solder, tiv thaiv lub solder los ntawm oxidized, thiab ua kom lub fluidity ntawm lub solder. Thaum soldering nyob rau hauv-kab Cheebtsam, yog hais tias lub Cheebtsam yog xeb, lawv yuav tsum tau muab pov tseg ua ntej, muab tso rau ntawm rosin thiab ironed nrog ib tug soldering hlau, thiab ces tinned. Thaum soldering SMD Cheebtsam, rosin kuj tseem siv tau los ua cov tin absorber nrog tooj liab hlau ntxiv rau cov flux.
6. Muab tshuaj txhuam
Thaum soldering nyuaj-rau-tin hlau thiab lwm yam khoom, solder paste tuaj yeem siv tau, uas tuaj yeem tshem tawm oxides ntawm cov hlau nto, uas yog corrosive.
Thaum soldering SMD Cheebtsam, qee zaum nws tuaj yeem siv los "noj" solder ua kom lub ntsej muag ci thiab ruaj khov.
7. rab phom kub
Lub phom cua kub yog ib qho cuab yeej siv cua kub cua tshuab los ntawm nws cov phom phom rau vuam thiab disassemble cov khoom. Cov txheej txheem yuav tsum tau ua rau nws siv yog qhov siab.
Cov phom cua kub tuaj yeem siv rau txhua yam ntawm kev tshem tawm lossis txhim kho cov khoom me me rau cov khoom loj ntawm kev sib xyaw ua ke. Nyob rau hauv lub sijhawm sib txawv, muaj qhov tshwj xeeb uas yuav tsum tau ua rau qhov ntsuas kub thiab cua ntim ntawm cov phom cua kub. Yog tias qhov ntsuas kub tsawg dhau, cov khoom yuav raug soldered. Yog tias qhov kub thiab txias heev, cov khoom siv thiab cov khoom siv hluav taws xob yuav raug puas tsuaj. Cov huab cua ntau dhau yuav tshuab cov khoom me me. Rau kev sib txuas zoo tib yam, tsis tas yuav muaj rab phom cua kub, thiab yuav tsis piav qhia hauv qab no.
8. Magnifying iav
Rau qee qhov SMD chips nrog tshwj xeeb me me thiab ntom pins, tom qab vuam, nws yog ib qho tsim nyog yuav tsum tau xyuas seb cov pins puas yog soldered ib txwm thiab seb puas muaj luv luv Circuit Court. Lub sijhawm no, nws yog ib qho nyuaj heev los siv tib neeg lub qhov muag, yog li siv lub iav magnifying, thiaj li yooj yim thiab ntseeg tau saib txhua qhov Soldering ntawm pins.
9. Cawv
Thaum siv rosin ua flux, nws yog ib qho yooj yim kom tso cov rosin ntau dhau ntawm lub rooj tsavxwm. Txhawm rau kom zoo nkauj, lub sijhawm no, koj tuaj yeem siv cawv paj rwb pob los ntxuav qhov chaw nrog cov rosin seem. Txhuam txhuam txhuam, kua nplaum, thiab lwm yam. Kuv yuav tsis nkag mus rau hauv cov ntsiab lus ntawm no, thiab cov phooj ywg uas muaj cov xwm txheej tuaj yeem nkag siab thiab siv nws hauv kev xyaum ua tes.
(Los ntawm sab laug mus rau sab xis, thawj kab yog: phom cua sov, tweezers, solder hlau. Qhov thib ob kab yog: hluav taws xob soldering hlau, rosin, tin suction daim kab xev)
