1. Nco ntsoov txhua tus saib xyuas qhov tshwm sim ua ntej tom qab tau txais lub rooj tsav xwm PCB liab qab kom pom seb puas muaj hluav taws xob luv luv, Circuit Court tawg thiab lwm yam teeb meem.Tom qab ntawd tau txais kev paub txog kev txhim kho schematic daim duab, thiab sib piv cov duab kos duab nrog PCB npo luam ntawv txheej kom tsis txhob muaj qhov sib txawv ntawm daim duab schematic thiab PCB.
2. Tom qab cov ntaub ntawv xav tau raureflow qhov cubyog npaj txhij, cov khoom yuav tsum tau muab cais.Tag nrho cov khoom tuaj yeem muab faib ua ntau pawg raws li lawv qhov ntau thiab tsawg rau qhov yooj yim ntawm kev vuam tom ntej.Daim ntawv teev cov khoom tiav yuav tsum tau luam tawm.Nyob rau hauv cov txheej txheem vuam, yog tias tsis muaj vuam tiav, hla tawm cov kev xaiv sib xws nrog tus cwj mem, txhawm rau pab txhawb kev ua haujlwm vuam tom ntej.
3. Ua ntejreflow soldering tshuab, siv esd ntsuas, xws li hnav lub nplhaib esd, tiv thaiv electrostatic puas rau cov khoom.Tom qab tag nrho cov khoom siv vuam tau npaj tiav, xyuas kom meej tias lub taub hau hlau yog huv si thiab huv si.Nws raug nquahu kom xaiv lub tiaj tiaj lub kaum sab xis rau qhov pib vuam.Thaum welding encapsulated Cheebtsam xws li 0603 hom, cov hlau soldering tuaj yeem hu tau zoo dua rau lub vuam ncoo, uas yooj yim rau vuam.Tau kawg, rau tus tswv, qhov no tsis yog teeb meem.
4. Thaum xaiv cov khoom siv rau vuam, vuam lawv nyob rau hauv kev txiav txim los ntawm qis mus rau siab thiab los ntawm me me mus rau loj.Txhawm rau kom tsis txhob muaj qhov vuam tsis yooj yim ntawm cov welded cov khoom loj dua rau cov khoom me me.Preferentially weld integrated circuit chips.
5. Ua ntej welding integrated circuit chips, xyuas kom meej tias cov chips tau muab tso rau hauv qhov tseeb.Rau lub nti npo luam ntawv txheej, cov duab plaub dav dav sawv cev rau qhov pib ntawm tus pin.Thaum vuam, ib tus pin ntawm cov nti yuav tsum tau kho ua ntej.Tom qab zoo-tuning txoj hauj lwm ntawm lub Cheebtsam, cov kab pheeb ces kaum ntawm cov nti yuav tsum tau kho kom cov Cheebtsam raug txuas mus rau txoj hauj lwm ua ntej welding.
6. Tsis muaj qhov zoo lossis tsis zoo electrode nyob rau hauv ceramic nti capacitors thiab regulator diodes nyob rau hauv voltage regulator circuits, tab sis nws yog tsim nyog los paub qhov zoo thiab tsis zoo electrode rau leds, tantalum capacitors thiab electrolytic capacitors.Rau cov capacitors thiab diode Cheebtsam, qhov kawg cim yuav tsum feem ntau tsis zoo.Nyob rau hauv pob ntawm SMT LED, muaj qhov zoo - qhov tsis zoo ntawm cov kev taw qhia ntawm lub teeb.Rau cov khoom siv encapsulated nrog silk screen txheeb xyuas ntawm diode Circuit Court daim duab, qhov tsis zoo diode huab yuav tsum muab tso rau ntawm qhov kawg ntawm txoj kab ntsug.
7. rau siv lead ua oscillator, passive siv lead ua oscillator feem ntau tsuas yog ob tus pins, thiab tsis muaj cov ntsiab lus zoo thiab tsis zoo.Lub active siv lead ua oscillator feem ntau muaj plaub tus pins.Ua tib zoo saib xyuas cov ntsiab lus ntawm txhua tus pin kom tsis txhob muaj qhov yuam kev welding.
8. Rau kev sib txuas ntawm cov khoom siv plug-in, xws li cov khoom siv hluav taws xob muaj feem cuam tshuam, tus pin ntawm lub cuab yeej tuaj yeem hloov kho ua ntej vuam.Tom qab cov khoom raug muab tso rau thiab kho, lub solder yog melted los ntawm cov hlau soldering nyob rau sab nraum qab thiab integrated rau pem hauv ntej los ntawm lub solder ncoo.Tsis txhob muab ntau solder, tab sis ua ntej cov khoom yuav tsum ruaj khov.
9. PCB tsim teeb meem pom thaum lub sij hawm vuam yuav tsum tau sau tseg nyob rau hauv lub sij hawm, xws li installation cuam tshuam, tsis raug pad loj tsim, tivthaiv ntim yuam kev, thiab lwm yam, rau kev txhim kho tom ntej.
10. Tom qab vuam, siv lub iav magnifying los xyuas cov pob qij txha thiab xyuas seb puas muaj cov vuam tsis xws luag lossis luv luv.
11. Tom qab ua tiav ntawm Circuit Board welding ua haujlwm, cawv thiab lwm yam tshuaj ntxuav tes yuav tsum tau siv los ntxuav qhov chaw ntawm lub rooj tsavxwm Circuit Court, tiv thaiv lub Circuit Court board nto txuas nrog hlau nti luv Circuit Court, tab sis kuj tuaj yeem ua rau lub rooj tsavxwm Circuit Court. huv thiab zoo nkauj dua.
