Soldering chaw nres tsheb nrog lawv tus kheej txhais tes

Thaum lub sij hawm kho, nti, motherboard, lub computer yog tsim nyog los siv ib tug soldering hlau. Tab sis nws tsis yog ib txwm yooj yim rau siv, vim hais tias nws sai sai overheats, muaj yog tsis muaj tau mus kho cov kub. Thiab ces koj xav tau ib tug mobile advanced rework chaw nres tsheb. Nws txhais tes nyob ib ncig ntawm nws kawm los mus tsim craftsmen.

Ib tug kev xaiv - tsim ib tug soldering chaw nres tsheb uas yog muab tso rau hauv lub hwj huam mov (ntau precisely, nws lub cev) los ntawm soldering, nyob rau qhov luaj li cas ntawm yim caum rau tsib caug-tsib thiab rau caum-tsib millimeters, uas yuav tsum tau kev cob cog rua thereto EPSN qub. Yuav kom ua tau ib lub soldering chaw nres tsheb yuav tsum mus kis tau cov kuj mus soldering rhaub resistive sensor thiab ib qho ntxiv npoo plev 1.6 millimeters.

Nyob rau hauv EPSN kos thermocouple multimeter los ntawm Tuam Tshoj. Lub xws board yuav tau qhov luaj li cas thiab plaub caug-peb mus rau peb caug-peb millimeters. Portable cov soldering chaw nres tsheb, nrog lawv txhais tes sib sau, ceeb toom txog npaj los siv soldering inscriptions rau ntawm cov zaub. Tom qab lub community launch xws muaj xws li ACC thiab nyeem cov inputs ntawm PC0, PC1 voltage theem. Nyob rau hauv cov ntaub ntawv uas, yog hais tias nws yog sib npaug zos rau cov mov voltage, thiaj li tsis muaj soldering, thiab ib tug inscription «yuam kev», qhov yuam kev yog qhia yog tso tawm.

Thaum lub voltage ntawm ib qho ntawm nws cov inputs yog tsawg tshaj li 4.5 volts, ces nws yog tau xaiv ib tug soldering hlau los yog ib tug resistive los yog ib tug thermocouple. Ntxiv mus, rau txhua yuav siv cov nyees khawm yuav tau kho cov kub. Cov zaub qhia tau hais tias cov blinking dot uas qhia uas ntawm lub pab kiag li lawm yog xaiv. Fais fab soldering hlau yuav tswj tau los ntawm PWM tes taws los piav VT1 tseem ceeb.

Thaum mus soldering chaw nres tsheb nrog lawv txhais tes, koj yuav ua li cas tsis muaj tus ntxiv transistors, vim hais tias thaum ib tug tam sim no ntawm 2 ma yog tau ib tug mob siab heev thiab ci ntsa iab. Cathodes ncaj qha kev cob cog rua rau lub maub los ports. LED nyias nyob ntawm tej yuav tsum solder lub rooj tsavxwm thiab txhim kho lub rear sab los ntawm txoj kev kub yaj nplaum.

Yuav kom haum raws li cov nyees khawm thiab cov zaub yuav tau ua kom qhov nyob rau hauv pem hauv ntej vaj huam sib luag. Daim duab pane nyob rau hauv daim iav duab luam tawm nyob rau cov pob tshab zaj duab xis, ib tug dawb muab tshuaj txhuam-tog nplaum kab xev los ntawm cov toner qauv txiav ncig ncig thiab ces glued mus rau vaj tse nyob. Rau qhov yooj yim ntawm cov nyees khawm yog zoo los lo rau lub vaj huam sib luag los ntawm txoj kev kub yaj nplaum.

Rau lub installation ua hauj lwm, them ntau dua, xws li cov motherboard los yog PC laptop, haum infrared soldering chaw nres tsheb, nrog lawv tus kheej ob txhais tes kom nws, dhau lawm, yog heev tiag tiag. Rau soldering nto mounted luam Circuit Court board thiab nws cov Cheebtsam (e.g., BGA) fits yog huab cua kub los yog infrared tawg.

Tus ntaus ntawv muaj ib tug tswj tsev, nyob rau hauv ib tug nyias muaj nyias ib vaj tse nyob. Nws muaj ob tug tso cua sov thiab fixtures rau cov laug cam. Txoj hauj lwm ntawm lub sab sauv yuav raug hloov nyob rau ib taag nqi. Qab rhaub muab tshav kub lub caij rau hluav taws xob hwj chim nyob rau hauv kilowatts ntawm ob thiab ib lub cheeb ntawm ob puas thiab nees nkaum millimeters. Upper rhaub - plaub tubular halogen lub teeb. Txhua yam ntawm lawv - 150 watts. Yog li, lub soldering chaw nres tsheb, nrog lawv txhais tes ua ke, ua ib tug tiav lawm saib.

Ib tug kos yuav tau ua los ntawm ib daim hlab ntawm lub matrix tshuab luam ntawv. Tus so ntawm lub ntsiab lus - kuj borrowed los ntawm cov laus computer cov khoom. Qhov taw qhia ua hauj lwm pab ob-kab kua siv lead ua module thiab ib tug. Es tsis txhob mem tes transformers yog zoo dua siv semistors thiab dab. Nws yuav tsum tau nco ntsoov hais tias hais tias lawv yog energized nyob rau ntawm lawv installation yuav tsum tau ceev faj li semistors. Nyob rau hauv tas li ntawd mus rau cov tsim nyog Cheebtsam yuav tsum tau rau soldering chaw nres tsheb fais fab mov uas nws muab tam sim no los ntawm ob raws, ib tug keyboard, zaub, buzzer thiab ntes zero.

Yog hais tias koj tsim soldering chaw nres tsheb nrog lawv txhais tes, thiab nws yog ib qho tseem ceeb kom paub tias ib co ntawm cov kev cai ntawm kev ua hauj lwm nrog nws muaj kev ruaj ntseg. Piv txwv li, peb yuav tsis tso cai rau halogen lub teeb tau tsuas nrog roj. Yog li ntawd, lawv yuav tsum tau ua tib zoo ntxuav nrog acetone los yog roj av, thiab ua ntej koj pib hnav tiv thaiv looj tsom iav dub.
