Nws yog cov cuab yeej rau desoldering (ntau ceg) cov khoom siv hluav taws xob nrog 3 lossis ntau dua tus pin. Txoj kev xav tom qab txoj haujlwm no yooj yim heev. Cov tshuaj yaj yaj yaj hauv cov thawv cua sov ua kom sov tag nrho cov neeg sib txuas ntawm cov khoom siv hluav taws xob tso ua ke nrog PCB ntawm cov cuab yeej no. Txhua yam koj yuav tsum tau ua yog tshem tawm cov khoom siv los ntawm PCB nrog cov yas los yog nrog tus txhuam hniav. Yog li nrog cov cuab yeej no koj tuaj yeem yooj yim desolder 25 tus pin LPT txuas los ntawm 2 sab PCB. Thawj tsab xov xwm ntawm kuv lub xaib ntawm no
Kauj Ruam 1: Tau Xaiv
Ua ntej pom qee cov tin tau, zoo li qhov no los ntawm daim duab.
Kauj Ruam 2: Npaj Tau
Tom qab ntawd txiav hauv qab ntawm lub peev xwm. Tom qab ntawd nws yuav siv los ua lub thawv rau yaj yaj. 1-2cm yog qhov siab txaus rau ntim.
Kauj Ruam 3: Kev Tsim Kho Cov Cua Kub
Rau lub rhaub dej koj xav tau lub rhaub hlau (NiCr). Feem ntau caled "cekas" los ntawm "nichrome". Yog tias koj tsis muaj, siv qee qhov los ntawm lub rhaub qub hauv lub tshuab ziab khaub ncaws lossis cua sov, thiab cua tawm 1m ntawm xaim. Ntsuas kev tiv thaiv vim tias koj yuav xav tau cov ntaub ntawv no tom qab kev tsim kho. Ua ntej suav koj yuav tsum muaj 2 qhov ntxiv. Lub zog thiab qhov hluav taws xob ntawm lub rhaub. Lub zog ntawm kuv lub rhaub dej yog 100W, kev pom zoo tsis mus rau hauv qab qhov ntawd vim tias nws siv sijhawm ntev heev rau yaj yaj tom qab fais fab tuag. Qhov hluav taws xob yuav tsum tau yoog raws lub zog siv uas koj yuav siv. Kuv muaj chav kuaj hluav taws xob los ntawm kev tswj hwm los ntawm 0-35V thiab kuv tau xaiv 30V rau qhov hluav taws xob ntawm kuv lub rhaub. Muab xam: U = 30 V P = 100 W rt = 28, 6 Ohm/m (tsis kam rau ib lub meter) Rt =? (tsis kam ntawm lub rhaub) Rt = U2 / P = 302 /100 = 900 /100 = 9 Ohma Ntev ntawm lub rhaub hluav taws xob L = Rt / rt = 9 /28, 6 = 0, 3m Yog tias koj tsis xav los suav qhov ntsuas thiab koj muaj lub zog siv hluav taws xob nrog kev tswj hwm, tsuas yog siv daim hlau, txuas nws mus rau lub zog hluav taws xob thiab nce qhov hluav taws xob kom txog thaum xaim (lub rhaub dej) tau txais lub teeb liab. Txoj kev no tuaj yeem siv rau kev tshuaj xyuas qhov ntsuas tsis tau. Hauv daim duab yog kuv lub rhaub dej. Coiled ntawm 3mm laum borer thiab txuas mus rau qhov ntev xav tau.
Kauj Ruam 4: Rho Rho Tawm
Lub rhaub dej tiav yuav tsum tau cais tawm ntawm cov tsev hlau. Kuv tau siv cov khoom siv hluav taws xob tshem tawm los ntawm lub tshuab ua kom sov ci ci qub. Yog tias koj tsis muaj cov rwb thaiv tsev yuav lawv hauv khw kho cov khoom siv hauv chav ua noj.
Kauj Ruam 5: Tau Txuas
Tau los ntawm kev pib ntawm cov ntawv yuav tsum tau txuas nrog lub tsev, rau lub hom phiaj tseem ceeb yog drilled los ntawm nruab nrab thiab PCB spacer tau txuas nrog tuaj yeem nrog cov ntsia hlau. Ntsia hlau yooj yim nrog ob peb txiv ntoo tuaj yeem siv tau.
Kauj Ruam 6: Rhaub Rho Tawm
Lub rhaub dej tau teeb tsa hauv lub qhov.
Kauj Ruam 7: Rhaub Rho Tawm
Lub rhaub dej tau nias kom tuaj yeem ua cov hniav nyiaj hniav kub los ntawm PC kiv cua.
Kauj Ruam 8: Cuam Tshuam
Cov ntsia hlau nrog cov txiv ntoo tau siv rau "ob txhais ceg" ntawm lub cuab yeej, thiab cov khoom siv sib txuas ua ke tau txuas los tuav lub qhov hluav taws xob.
Kauj ruam 9: Thawj Khiav
Cov cuab yeej desoldering txuas nrog lub zog xa khoom, thiab kev sib tsoo ntawm qhov sib txuas tau yaj hauv lub peev xwm.
Kauj ruam 10: Cov cuab yeej siv
Ntawm cov duab tom ntej desoldering txheej txheem tau qhia ib qib zuj zus.
Kauj ruam 11:
Cov vis dis aus luv luv ntawm cov cuab yeej siv: Video 1 640x480, 18.7MBVideo 2 320x240, 18MBVideo 3 320x240, 19MB

Desoldering | Cov Txheej Txheem Txhim Kho: Qee lub sij hawm thaum koj tab tom siv, koj tsuas yog xav tshem qee qhov. Kuv tab tom yuav qhia ob peb txoj hauv kev rau kev tshem tawm cov khoom uas tau txuas rau lub rooj tsav xwm hauv Circuit. Rau txhua txoj hauv kev no ib feem koj tab tom sim tshem tawm yuav ua kom sov, yog li ceev faj yog tias koj
Kev Tsim Qauv Duab Duab/Duab Duab Duab: 4 Kauj Ruam
Kev Tsim Qauv Duab Duab/Duab Duab Duab: Nyob zoo txhua tus, Hauv qhov kev qhia no, Kuv yuav qhia koj cov txheej txheem ntawm yuav ua li cas thiaj tsim 3D qauv siv cov duab digital. Cov txheej txheem hu ua Photogrammetry, tseem hu ua Image-Based Modeling (IBM). Tshwj xeeb, hom txheej txheem no tau siv los rov ua dua
