Ib tug soldering hlau yog yuav tsum tau rau soldering thiab disassembling Cheebtsam.
1. Tshem tawm ntawm txheej oxide. Lub hom phiaj ntawm kev tshem tawm cov oxide txheej yog ua kom yooj yim rau cov hlau taub hau kom dipped rau hauv solder thaum vuam. Ua ntej siv cov hlau nplaum, koj tuaj yeem siv rab riam los yog cov ntaub ntawv los maj mam tshem tawm cov oxide txheej ntawm lub taub hau hlau. Tom qab txheej txheej oxide raug tshem tawm, cov hlau yuav raug nthuav tawm. luster.
2. Dip hauv flux. Raws li pom nyob rau hauv daim duab b, tom qab cov oxide txheej ntawm lub soldering hlau taub raug tshem tawm, energize lub soldering hlau kom sov lub ntsis, thiab ces dipped lub taub hau nyob rau hauv rosin. Koj yuav pom rosin vapor emitting los ntawm lub ntsis. Lub luag haujlwm ntawm rosin yog los tiv thaiv cov hlau nplaum los ntawm oxidizing ntawm qhov kub thiab txias thiab txhim khu lub fluidity ntawm cov solder, ua rau vuam yooj yim dua.
3. Dai tin. Thaum lub taub hau hlau yog dipped nyob rau hauv rosin thiab ncav cuag ib tug txaus kub, rosin vapor yuav tshwm sim los ntawm lub soldering hlau taub. Siv lub taub hau ntawm lub taub hau ntawm lub taub hau thiab siv ib txheej ntawm cov hlua rau lub taub hau ntawm lub taub hau.
Qhov kom zoo dua ntawm dai tin ntawm lub taub hau hlau yog los tiv thaiv cov hlau nplaum ntawm oxidation thiab ua kom yooj yim rau vuam cov khoom. Thaum lub taub hau hlau yog "hlawv", uas yog, qhov kub ntawm lub taub hau ntawm lub taub hau yog siab dhau, lub taub hau ntawm lub taub hau ntawm lub taub hau yog evaporates, thiab cov hlau taub hau yog kub hnyiab dub thiab oxidized, nws yuav nyuaj rau solder. cov khoom. Lub sijhawm no, txheej oxide yuav tsum tau muab tshem tawm thiab tom qab ntawd tinned ua ntej siv. Yog li ntawd, thaum lub soldering hlau tsis siv rau lub sij hawm ntev, lub hwj chim mov yuav tsum tau unplugged los tiv thaiv lub soldering hlau los ntawm "kub tawm".
4. Vuam ntawm cov khoom
Thaum welding Cheebtsam, ua ntej maj mam muab tshem tawm cov oxide txheej ntawm cov pins ntawm lub Cheebtsam yuav tsum tau welded, ces energize lub soldering hlau, poob rau hauv rosin tom qab cua sov, thiab thaum lub kub ntawm lub soldering hlau taub yog txaus, tig lub soldering hlau. lub kaum sab xis ntawm 45 degree. Nias nws ntawm cov ntawv ci tooj liab ntawm ib sab ntawm cov pins ntawm cov khoom siv los ua rau ntawm lub rooj tsav xwm luam tawm, thiab tom qab ntawd kov lub taub hau hlau. Cov hlau nplaum melts thiab dhau los ua kua, uas yuav ntws los ntawm cov khoom siv pins. Thaum lub sij hawm no, txav lub taub hau ntawm cov hlau. Thaum lub solder qhib, cov khoom siv pins thiab cov ntawv ci tooj liab ntawm lub rooj tsav xwm luam tawm yog welded ua ke.
Thaum vuam Cheebtsam, lub taub hau hlau yuav tsum tsis txhob nyob rau hauv kev sib cuag nrog lub Circuit Court board thiab cov khoom rau ntev heev kom tsis txhob muaj kev puas tsuaj rau lub Circuit Court board thiab cov khoom. Cov txheej txheem vuam yuav tsum ua kom tiav hauv 1.5 mus rau 4 vib nas this. Thaum lub sij hawm welding, cov pob qij txha yuav tsum du thiab cov solder yog sib npaug.
5. Disassembly ntawm cov khoom
Thaum disassembling cov khoom ntawm lub rooj tsav xwm luam tawm, siv lub taub hau hlau los kov cov pob qij txha ntawm cov khoom siv pins. Tom qab lub solder ntawm lub solder pob qij txha melts, rub tawm cov tivthaiv pins ntawm lwm sab ntawm lub Circuit Court board. , thiab ces siv tib txoj kev los solder lwm tus pin. Txoj kev no yog yooj yim heev rau disassemble cov khoom uas muaj tsawg dua 3 pins, tab sis nws yog ib qho nyuaj rau disassemble Cheebtsam nrog ntau tshaj 4 pins (xws li integrated circuits).
