Kev paub thiab kev txawj ntse los tiv thaiv tsis zoo soldering nrog hluav taws xob soldering hlau
1. Xaiv cov solder tsim nyog. Nws raug nquahu kom siv cov ntsiab lus qis melting solder hlau rau vuam cov khoom siv hluav taws xob.
2. Flux, siv 25% rosin yaj hauv 75% cawv (qhov hnyav piv) raws li cov flux.
3. Cov hlau nplaum yuav tsum tau tinned ua ntej siv. Txoj kev: Kub lub hlau soldering. Thaum lub solder tsuas yog melted, thov flux, thiab ces siv lub solder tusyees ntawm lub soldering hlau taub kom lub soldering hlau taub yog tusyees coated. tin.
4. Vuam txoj kev: Polish lub ncoo thiab tivthaiv pins huv si nrog zoo sandpaper, thiab siv flux. Dip tus nqi tsim nyog ntawm solder nrog lub ntsis ntawm cov hlau soldering thiab kov nws mus rau qhov sib koom ua ke. Tom qab tag nrho cov solder ntawm lub solder sib koom ua ke melts thiab immerses cov hlau lead ntawm cov tivthaiv, maj mam nqa lub ntsis ntawm cov hlau soldering upwards raws cov hlau lead ntawm cov khoom thiab deb ntawm lub solder sib koom.
5. Lub sijhawm vuam yuav tsum tsis txhob ntev dhau, txwv tsis pub nws yuav yooj yim hlawv cov khoom. Koj tuaj yeem siv cov tweezers los tuav cov pins los pab kom cov cua sov.
6. Lub solder sib koom yuav tsum nyob rau hauv cov duab ntawm ib tug sinusoidal nthwv dej ncov, 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 flux seem ntawm lub rooj tsav xwm Circuit Court kom tsis txhob muaj cov pa roj carbonized los ntawm kev cuam tshuam rau kev ua haujlwm ntawm lub voj voog.
8. Thaum kawg, weld cov kev sib txuas ua ke kom ntseeg tau tias kev txhim khu kev qha ntawm cov hlau soldering, los yog siv cov hluav taws xob seem rau vuam tom qab fais fab tuag. Koj tuaj yeem siv lub qhov (socket) tshwj xeeb rau kev sib xyaw ua ke. Tom qab soldering lub qhov (socket), ntsaws lub integrated circuit nyob rau hauv.
9. Lub soldering hlau yuav tsum tau muab tso rau ntawm lub soldering hlau sawv thaum tsis siv.
Cov kauj ruam yooj yim ntawm vuam
1. Txhawm rau ua kom cov hlau nplaum sib txuas ua haujlwm zoo, ua ntej txhuam cov hlau nplaum nrog cov ntawv xuab zeb. Ceev faj kom tsis txhob hnav cov hlau nplaum ntau dhau, vim tias hnav ntau dhau tuaj yeem ua rau oxidation yooj yim.
2. Qhib lub tshuab hluav taws xob thiab ua kom sov. Thaum qhov kub thiab txias tuaj yeem yaj lub solder, thov cov flux mus rau lub taub hau ntawm lub taub hau, thiab tom qab ntawd siv lub solder sib npaug ntawm cov hlau taub hau.
3. Kov lub taub hau nrog cov hlua khi mus rau qhov taw tes. Thaum lub solder yog immersed nyob rau hauv lub soldering point, maj mam rub lub soldering hlau.
4. Tom qab welding tiav lawm, tua lub hwj chim ntawm cov hlau soldering thiab muab tso rau ntawm lub soldering hlau sawv. Ceev faj kom tsis txhob kub hnyiab los ntawm cov cua sov seem.
5. Cov dej ntws seem ntawm lub rooj tsav xwm hauv Circuit Court tuaj yeem ntxuav nrog cawv kom tsis txhob muaj cov pa roj carbonized los ntawm kev cuam tshuam rau kev ua haujlwm ntawm lub voj voog.
