Ib tug soldering hlau yuav tsum tau solder thiab disassemble Cheebtsam.
Vuam demolition ntawm kev npaj ua ntej
1, tshem tawm cov txheej txheej oxide, ntxiv rau txheej oxide yog txhawm rau txhawm rau vuam lub taub hau ntawm lub taub hau tuaj yeem yooj yim dipped rau hauv cov hlau, hauv kev siv cov hlau soldering ua ntej, tuaj yeem siv riam los yog cov ntaub ntawv los maj mam tshem tawm. oxide txheej ntawm lub taub hau ntawm cov hlau soldering, oxide txheej scraped tawm yuav nthuav tawm cov hlau luster.
2, flux ua. Tom qab tshem tawm cov txheej txheem oxidation ntawm lub taub hau ntawm lub taub hau, cov hlau soldering yog siv los ua kom cov hlau taub hau kub, thiab tom qab ntawd cov hlau taub hau tau dipped hauv rosin (hluav taws xobcov khw muag khoom, tsis txhob mus tom khw), koj yuav pom lub taub hau ntawm cov hlau soldering ntawm rosin vapor tawm. (Cov neeg mob obsessive-compulsive tuaj yeem siv lub ntsej muag los sim ntsuas qhov ntsuas kub, thaum kuv tseem yog menyuam yaus, txhua zaus kuv txiv ntawm cov hlau soldering chaw taws teeb tswj Circuit Court boards, kuv xav sim haus luam yeeb qhov kub ntawm lub taub hau soldering)
Lub luag hauj lwm ntawm rosin yog los tiv thaiv oxidation ntawm lub taub hau hlau soldering ntawm qhov kub thiab txias, thiab txhim khu lub fluidity ntawm lub solder, kom vuam yog yooj yim dua.
3, kab txaij. Thaum lub taub hau hlau yog dipped nyob rau hauv rosin kom ncav cuag qhov kub txaus, muaj rosin vapor tawm ntawm lub taub hau ntawm cov hlau soldering, thiab lub taub hau ntawm cov hlau soldering yog coated nrog solder.
Rau lub taub hau ntawm lub taub hau dai tin cov txiaj ntsig yog los tiv thaiv lub taub hau ntawm lub taub hau tsis oxidized, thiab ua kom lub taub hau ntawm lub taub hau yooj yim rau vuam cov khoom, ib zaug lub taub hau hlau "hluav taws kub hnyiab", uas yog, lub taub hau hlau soldering kub yog. High soldering hlau taub hau ntawm lub solder evaporates, lub taub hau soldering hlau yog hlawv dub oxidation, vuam Cheebtsam yog heev yooj yim mus nqa tawm, lub sij hawm no koj yuav tsum tau khawb tawm oxidised txheej thiab ces dai tin thiaj li siv tau. Yog li ntawd, thaum lub soldering hlau tsis siv rau ib ntev lub sij hawm, koj yuav tsum tau unplug lub hwj chim mov los mus tiv thaiv lub soldering hlau "hlawv tuag".
4, vuam ntawm cov khoom
Soldering Cheebtsam, ua ntej ntawm tag nrho cov, yuav tsum tau soldered Cheebtsam ntawm cov pins ntawm lub oxide txheej maj mam muab tshem tawm, thiab ces electrify lub soldering hlau, tshav kub dipped nyob rau hauv rosin, thaum lub soldering hlau taub hau kub txaus, lub soldering hlau taub hau ntawm lub kaum sab xis. ntawm 45 degree nias nyob rau hauv lub rooj tsavxwm luam ntawv yuav tsum tau soldered Cheebtsam ntawm ib sab ntawm tus pins ntawm cov ntawv ci tooj liab, thiab tom qab ntawd yuav yog cov hlau nplaum kov lub taub hau hlau, cov hlau nplaum melted rau hauv daim ntawv ua kua, nws yuav ntws ncig cov pins. ntawm cov khoom, lub sijhawm no yuav yog lub taub hau ntawm cov hlau txav mus! Thaum lub sij hawm no, lub taub hau hlau soldering yuav raug tshem tawm, lub solder txias yuav tiv thaiv pins thiab luam tawm Circuit Court board tooj liab ntawv ci welded ua ke.
Cov khoom siv soldering thaum lub vuam hlau txuas nrog lub rooj tsav xwm luam tawm thiab cov khoom siv tsis ntev dhau los, kom tsis txhob ua rau cov khoom siv hluav taws xob thiab cov khoom puas ntsoog, cov txheej txheem vuam yuav tsum ua kom tiav li ntawm 1.5 ~ 4s, vuam yuav tsum muaj cov pob qij txha du thiab uniform faib ntawm solder.
5, Disassembly ntawm cov khoom
Nyob rau hauv lub dismantling ntawm lub Cheebtsam ntawm lub luam Circuit Court board, lub soldering hlau nrog lub ntsis ntawm lub soldering hlau mus cuag cov tivthaiv pins ntawm lub vuam taw tes, yuav tsum tau soldered nyob rau hauv lub vuam point ntawm lub solder melted, nyob rau hauv lwm yam sab ntawm lub Circuit Court. lub rooj tsavxwm yuav yog cov khoom siv pins rub tawm, thiab tom qab ntawd welded tib txoj kev nyob rau hauv lwm tus pin. Txoj kev no yog yooj yim heev rau disassemble Cheebtsam nrog tsawg dua 3 pins, tab sis disassembling Cheebtsam nrog ntau tshaj 4 pins (xws li, integrated circuits) yog nyuaj dua.
Niaj hnub no, lub pob ntawm kev sib xyaw ua ke yog qhov muag heev, zoo nkauj zoo li tus poj niam me me, koj xav tau qhov twg?
Kev tshem tawm ntau tshaj 4 tus pins ntawm cov khoom siv tuaj yeem siv los nqus cov tin soldering hlau, tuaj yeem siv nrog cov hlau zoo tib yam nrog kev pab los ntawm stainless hlau hollow casing los yog koob txhaj koob tshuaj tivthaiv (kev lag luam hluav taws xob muaj, rab koob los ua ib qho tuaj yeem ua tau. be) dismantle.
Multi-pin Cheebtsam disassembly txoj kev qhia nyob rau hauv daim duab hauv qab no, nrog rau lub taub hau soldering hlau hu rau lub Cheebtsam ntawm ib tug pin soldering point, thaum tus taw ntawm lub soldering point ntawm lub solder melting, yuav yog qhov tsim nyog loj ntawm lub koob txhaj tshuaj nyob rau hauv tus pin. thiab tig, kom cov pins tivthaiv thiab cov ntawv luam tawm Circuit Court board solder tooj liab foil tshem tawm ntawm lub rooj tsavxwm Circuit Court, thiab tom qab ntawd tshem tawm lub taub hau hlau, thiab rub tawm lub koob txhaj tshuaj, kom cov khoom siv pins nrog cov ntawv ci tooj liab ntawm cov ntawv luam tawm. Circuit board detached los ntawm, thiab ces tib yam Tib txoj kev los ua rau lwm tus pins ntawm cov tivthaiv thiab cov luam Circuit Court board tooj liab foil detached, thiab thaum kawg cov tivthaiv yuav raug rub los ntawm lub Circuit Court board.
