Vuam thiab disassembly ntawm cov khoom yuav tsum tau siv cov hluav taws xob soldering hlau
Kev npaj ua haujlwm ua ntej vuam thiab dismantling
1. Txhawm rau tshem tawm cov txheej txheem oxide, nws yog ib qho tsim nyog yuav tau yooj yim dipped lub taub hau soldering rau hauv lub solder thaum vuam. Ua ntej siv hluav taws xob soldering hlau, koj tuaj yeem maj mam tshem tawm cov oxide txheej ntawm lub taub hau ntawm lub taub hau nrog rab riam me me los yog cov ntaub ntawv. Tom qab scraping tawm ntawm oxide txheej, nws yuav nthuav tawm ib tug hlau luster.
2. Dip nyob rau hauv soldering flux. Raws li pom hauv daim duab B, tom qab tshem tawm cov oxide txheej ntawm lub taub hau hlau, siv hluav taws xob rau cov hlau nplaum kom sov. Tom qab ntawd, txhuam lub taub hau hlau rau hauv rosin (muaj nyob rau hauv kev lag luam hluav taws xob, tsis txhob mus rau cov khw muag zaub), thiab koj yuav pom rosin vapor tawm ntawm lub taub hau hlau.
3. Dai tin. Thaum lub taub hau hlau yog dipped hauv rosin kom ncav cuag qhov kub txaus, rosin vapor yuav tawm los ntawm cov hlau taub hau. Siv cov solder rau ntawm qhov kawg ntawm lub taub hau ntawm lub taub hau thiab ib txheej ntawm solder ntawm lub ntsis.
Qhov kom zoo dua ntawm dai tin rau ntawm lub taub hau hlau yog los tiv thaiv lub taub hau hlau los ntawm oxidation thiab ua kom yooj yim rau cov khoom siv. Thaum lub taub hau hlau "kub tawm", uas yog, yog tias qhov kub thiab txias ntawm lub taub hau ntawm lub taub hau yog siab dhau, lub taub hau ntawm lub taub hau ntawm lub taub hau yuav evaporate, thiab lub taub hau hlau yuav raug hlawv dub thiab oxidized, ua rau nws nyuaj. rau solder Cheebtsam. Hauv qhov no, txheej txheej oxide yuav tsum tau muab tshem tawm ua ntej dai tin ua ntej siv. Yog li ntawd, thaum lub soldering hlau tsis siv rau lub sij hawm ntev, lub hwj chim yuav tsum tau unplugged los tiv thaiv lub soldering hlau los ntawm burning tawm.
4. Vuam ntawm cov khoom
Thaum soldering Cheebtsam, ua ntej maj mam muab tshem tawm cov oxide txheej ntawm cov pins ntawm lub Cheebtsam yuav tsum tau soldered, ces siv hluav taws xob rau cov hlau soldering, sov nws li, thiab poob rau hauv rosin. Thaum qhov kub ntawm lub taub hau hlau soldering txaus, nias lub taub hau ntawm lub taub hau ntawm lub kaum sab xis ntawm 45 degree ntawm cov ntawv ci tooj liab ntawm ib sab ntawm cov pins ntawm cov khoom kom raug soldered ntawm lub rooj tsav xwm luam tawm. Tom qab ntawd, hu rau cov hlau nplaum nrog lub taub hau hlau, thiab cov hlau nplaum yuav yaj mus rau hauv cov kua hauv lub xeev uas yuav ntws ncig cov pins ntawm cov khoom. Lub sijhawm no, txav lub taub hau ntawm lub taub hau mus, thiab cov hlau nplaum yuav txias kom welding cov pins ntawm cov khoom mus rau cov ntawv ci tooj liab ntawm cov ntawv luam tawm.
5. Disassembly ntawm cov khoom
Thaum disassembling Cheebtsam ntawm lub rooj tsavxwm luam tawm, siv lub hau ntawm lub tshuab hluav taws xob los tiv tauj cov khoom sib txuas ntawm cov khoom siv tus pin. Tom qab lub solder ntawm lub solder sib koom ua ke melts, rub tawm cov tivthaiv tus pin nyob rau sab ntawm lub Circuit Court board, thiab ces solder rau lwm tus pin siv tib txoj kev. Txoj kev no yog qhov yooj yim rau kev tshem tawm cov khoom siv nrog tsawg dua 3 tus pins, tab sis nws yog qhov nyuaj rau disassemble cov khoom nrog ntau tshaj 4 tus pins (xws li kev sib xyaw ua ke).
