Kev siv rosin (soldering hlau vuam)
Cov hlau soldering tsis kub lossis tsis kub dhau thaum nws ntsaws rau hauv
1) Txheeb xyuas seb qhov hluav taws xob hluav taws xob puas qis dua AC210V (qhov voltage ib txwm yuav tsum yog AC220V), yog tias qhov hluav taws xob tsawg dhau, nws yuav ua rau tsis txaus cua sov thiab teeb meem hauv kev sib txuas.
2) Lub taub hau hlau yog oxidized los yog qhov txuas ntawm lub hauv paus kawg ntawm cov hlau taub hau thiab cov phab ntsa sab hauv ntawm lub raj sab nraud yog oxidized.
Yuav ua li cas siv cov hlau soldering kom raug
1. Xaiv cov solder haum, tsis tshua muaj melting point solder hlau rau vuam cov khoom siv hluav taws xob yuav tsum tau xaiv.
2. Flux, siv 25 feem pua rosin yaj hauv 75 feem pua ntawm cawv (los ntawm qhov hnyav) raws li flux.
3. Lub tshuab hluav taws xob yuav tsum tau tinned ua ntej siv. Txoj kev tshwj xeeb yog: cua sov cov hluav taws xob soldering hlau, thiab thaum nws muaj peev xwm yaj lub solder, thov flux, thiab ces thov solder tusyees ntawm lub soldering hlau taub, thiaj li hais tias lub soldering hlau taub yuav tsum tau noj tusyees ib txheej ntawm tin.
4. Txoj kev soldering, polish lub ncoo thiab tivthaiv pins nrog zoo xuab zeb, thiab siv flux. Dip tus nqi tsim nyog ntawm solder nrog lub ntsis ntawm cov hlau soldering thiab kov lub solder sib koom. Tom qab lub solder ntawm lub solder sib koom yog kiag li melted thiab immersed nyob rau hauv cov khoom siv lead ua, lub soldering hlau taub yog maj mam muab tshem tawm ntawm lub solder sib koom ua ke raws li cov hlau lead ntawm cov khoom.
5. Lub sijhawm vuam yuav tsum tsis txhob ntev dhau, txwv tsis pub nws yog qhov yooj yim rau hlawv cov khoom. Yog tias tsim nyog, siv cov tweezers txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua kom sov.
6. Cov pob qij txha yuav tsum nyob rau hauv cov duab ntawm sine yoj peaks, qhov saum npoo yuav tsum ci thiab du, tsis muaj tin pos, thiab tus nqi ntawm cov tin yuav tsum nyob nruab nrab.
7. Tom qab lub soldering tiav lawm, siv cawv los ntxuav cov seem ntawm lub rooj tsavxwm Circuit Court kom tsis txhob muaj cov pa roj carbonized los ntawm kev cuam tshuam rau kev ua haujlwm ntawm lub voj voog.
8. Cov kev sib xyaw ua ke yuav tsum tau soldered kawg, thiab cov hluav taws xob soldering hlau yuav tsum muaj kev ntseeg siab hauv av, los yog siv cov hluav taws kub uas seem rau soldering tom qab fais fab tuag. Los yog siv lub qhov (socket) tshwj xeeb rau kev sib xyaw ua ke, thiab tom qab ntawd ntsaws cov kev sib txuas ua ke tom qab soldering lub qhov (socket).
9. Cov hluav taws xob soldering hlau yuav tsum tau muab tso rau ntawm cov hlau soldering.
Rosin yog siv los ua flux nyob rau hauv vuam thiab ua raws li ib tug flux.
Kev hais lus theoretical, lub melting point ntawm flux yog qis dua li ntawm solder, thiab nws qhov tshwj xeeb lub ntiajteb txawj nqus, viscosity, thiab nto nro yog me dua li ntawm solder. Yog li ntawd, thaum soldering, cov flux melts ua ntej, thiab sai sai ntws thiab npog cov saum npoo ntawm solder kom cais cov huab cua thiab tiv thaiv cov hlau nto. Oxidation, thiab tuaj yeem hnov mob nrog oxide zaj duab xis rau ntawm qhov chaw ntawm lub solder thiab cov hlau yuav tsum tau welded ntawm qhov kub thiab txias kom yaj nws thiab rov qab cov hlau ntshiab. Tsim nyog soldering tin pab kom solder tawm ib tug txaus siab solder sib koom ua ke zoo thiab tuav lub nto gloss ntawm cov pob qij txha.
Rosin yog cov feem ntau siv flux, nws yog nruab nrab thiab yuav tsis corrode Circuit Court Cheebtsam thiab soldering hlau tswv yim.
Yog tias nws yog lub rooj tsav xwm luam tawm tshiab, thov ib txheej ntawm rosin naj hoom rau saum npoo ntawm daim ntawv hlau ua ntej soldering. Yog hais tias nws yog ib lub rooj tsav xwm Circuit Court uas twb tau ua lawm, nws tuaj yeem ncaj qha soldered. Qhov tseeb, kev siv rosin nyob ntawm tus kheej tus cwj pwm. Qee tus neeg yuav poob qhov taub ntawm cov hlau nplaum hauv rosin txhua zaus lawv muab cov khoom siv; Dip ib co rosin rau saum. Kev siv cov rosin kuj yog ib qho yooj yim heev, tsuas yog qhib lub thawv rosin thiab poob lub zog ntawm cov hlau nplaum rau ntawm nws.
Yog tias cov tub ntxhais siv tau siv rau vuam, nws yog ib qho tsim nyog yuav tau ntxiv qee cov rosin; Yog hais tias rosin tin solder hlau yog siv (flux yog qhwv hauv cov tub ntxhais hlau), rosin tsis tas yuav tsum tau.
Txij li cov hlau nto yuav tsim ib txheej ntawm oxide zaj duab xis tom qab kev sib cuag nrog huab cua, qhov kub thiab txias, qhov hnyav dua qhov oxidation. Cov txheej txheem ntawm oxide zaj duab xis tiv thaiv cov kua nplaum los ntawm ntub cov hlau, ib yam li cov roj ntawm lub khob yuav tiv thaiv dej los ntawm ntub dej. Flux yog ib yam khoom tshwj xeeb uas siv los tshem tawm oxide zaj duab xis, tseem hu ua flux. Flux muaj peb txoj haujlwm:
1. Ntxiv rau oxide zaj duab xis. Lub essence yog hais tias cov tshuaj nyob rau hauv lub flux undergo ib tug txo cov tshuaj tiv thaiv kom tshem tawm cov oxide zaj duab xis, thiab cov tshuaj tiv thaiv cov khoom yuav raug tshem tawm slag, ntab rau saum npoo ntawm solder.
2. Tiv thaiv oxidation. Tom qab nws melts, nws ntab rau saum npoo ntawm lub solder, tsim ib txheej cais, yog li tiv thaiv oxidation ntawm soldering nto.
3. Txo qhov nro ntawm qhov chaw, ua kom cov dej ntws ntawm cov solder, thiab pab cov solder ntub cov vuam.
