Soldering thiab disassembly ntawm cov khoom yuav tsum tau ib tug soldering hlau.
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, siv cov hlau soldering ua ntej, tuaj yeem siv rab riam los yog cov ntaub ntawv los maj mam tshem tawm. oxidized txheej ntawm lub taub hau hlau soldering, oxide txheej scraped tawm yuav nthuav tawm cov hlau luster.
2, flux ua. Xws li b daim duab, lub taub hau hlau taub hau oxidized txheej tshem tawm, mus rau cov hlau soldering energized kom lub taub hau hlau yog kub, thiab tom qab ntawd lub taub hau hlau soldering dipped nyob rau hauv rosin (lub khw muag khoom hluav taws xob, tsis txhob mus tom khw), yuav pom lub taub hau 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 soldering hlau ntawm lub rooj tsav xwm tswj chaw taws teeb, 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 ntawm lub taub hau ntawm qhov kub thiab txias, thiab txhim khu lub fluidity ntawm lub solder, kom lub vuam yog yooj yim dua mus nqa tawm.
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 hlau tsis muaj 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 ntawm lub taub hau kub yog. High soldering hlau taub hau ntawm lub solder evaporated, lub taub hau hlau soldering tau hlawv dub oxidation, vuam Cheebtsam yog heev nyuaj rau nqa tawm, lub sij hawm no koj yuav tsum tau khawb tawm oxidized 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 oxidized txheej maj mam muab scraped tawm, thiab ces mus rau lub soldering hlau energized, rhuab thiab ces dipped nyob rau hauv rosin, thaum lub soldering hlau taub hau kub yog txaus, 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 ib sab ntawm cov pins ntawm cov khoom ntawm cov ntawv ci tooj liab, thiab tom qab ntawd yuav yog cov hlau xaim hu rau lub taub hau ntawm lub taub hau, solder hlau melted rau hauv daim ntawv ua kua, nws yuav ntws ncig lub pins ntawm cov tivthaiv, lub sijhawm no yuav yog lub taub hau ntawm cov hlau kom txav mus deb! Thaum lub sij hawm no, tshem tawm lub taub hau hlau soldering, solder txias yuav tiv thaiv pins thiab luam Circuit Court board tooj liab ntawv ci welded ua ke.
Soldering Cheebtsam thaum lub soldering hlau ntsis tiv tauj nrog lub Circuit Court board thiab cov khoom tsis ntev dhau lawm, thiaj li tsis mus ua puas lub Circuit Court board thiab cov khoom, cov txheej txheem soldering yuav tsum tau ua kom tiav nyob rau hauv 1.5 ~ 4s, soldering yuav tsum tau ntawm cov solder pob qij txha du. thiab uniform faib ntawm solder. (laus tsav tsheb coj kuv)
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 soldering point, yuav tsum tau soldered nyob rau hauv lub soldering 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 yam li lwm tus pin. Hom kev disassembly ntawm cov nram qab no 3 pins ntawm cov khoom yog yooj yim heev, tab sis disassembly ntau tshaj 4 pins ntawm cov khoom (xws li integrated circuits) yog nyuaj dua.
