Yuav ua li cas tuav ib tug soldering hlau
(1) Yuav tuav tus cwj mem li cas. Haum rau lub teeb yuag hlau xws li 30W sab hauv cua sov. Nws lub taub hau hlau yog ncaj nraim, thiab lub taub hau kawg tau muab tso rau hauv ib qho bevel lossis conical zoo, uas yog tsim rau cov ntaub qhwv nrog ib qho chaw me me.
(2), Kev siv lub nrig. Nws yog tsim rau high-power soldering hlau. Peb feem ntau tsis siv high-power soldering irons rau hluav taws xob ntau lawm (tsis qhia ntawm no).
Muaj ntau txoj hauv kev ntawm soldering ua rau ntawm PCB.
Muaj ob hom kev luam tawm Circuit Board: ib sab thiab ob sab. Qhov los ntawm qhov ntawm nws feem ntau tsis yog-metallized, tab sis txhawm rau ua kom cov khoom sib txuas ntawm lub rooj tsav xwm Circuit Court kom ruaj khov thiab ntseeg tau, feem ntau ntawm cov qhov ntawm cov ntawv luam tawm Circuit Board ntawm cov khoom siv hluav taws xob tam sim no metallized. Txoj kev ntawm soldering cov leads ntawm lub rooj tsavxwm ib leeg-ib sab:
(1) Ncaj nraim ntawm lub taub hau txiav. Cov hlau lead mus dhau ntawm qhov ncaj qha. Thaum soldering, ua kom tsim nyog tus nqi ntawm molten solder tusyees nyob ib ncig ntawm lub tin-stained txhuas hlau saum lub ncoo los ua lub khob hliav qab. Tom qab nws txias thiab solidifies, txiav tawm cov hlau lead ntau dhau. (saib blackboard rau txoj kev tshwj xeeb)
(2), faus ncaj qha. Cov hlau lead los ntawm lub qhov tsuas yog raug rau qhov ntev uas tsim nyog, thiab cov molten solder faus cov hlau lead hauv qhov sib koom ua ke. Hom kev sib koom tes no yog kwv yees li hemispherical. Txawm hais tias nws yog qhov zoo nkauj, tshwj xeeb yuav tsum tau them nyiaj rau kev tiv thaiv tsis muaj tseeb.
Tiv thaiv kev vuam tsis zoo
Soldering yog ib qho txuj ci tseem ceeb uas cov kws tshaj lij xov tooj cua yuav tsum paub, thiab nws yuav siv sij hawm ntau los xyaum ua nws.
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. Cov hlau nplaum yuav tsum tau tinned ua ntej siv. Txoj kev tshwj xeeb yog: cua sov cov hlau soldering, thiab thaum lub solder yuav yaj, thov flux, thiab ces thov solder tusyees ntawm lub soldering hlau taub, kom lub soldering hlau taub yuav sib npaug zos coated 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 maj mam muab los ntawm cov hlau lead ntawm cov tivthaiv thiab tawm lub solder sib koom.
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.
