Kev paub txias
Dab tsi yog xim ntawm lub rooj tsavxwm PCB, raws li lub npe qhia, thaum tau txais lub rooj tsavxwm PCB, qhov yooj yim tshaj plaws kom pom cov xim ntawm cov roj ntawm lub rooj tsavxwm, uas yog, peb feem ntau xa mus rau cov xim ntawm lub rooj tsavxwm PCB, cov xim sib txawv. yog ntsuab, xiav, liab thiab dub thiab lwm yam.Cov nram qab no Xiaobian qhia lawv txoj kev nkag siab ntawm cov xim sib txawv.
- 1, tus cwj mem ntsuab yog nyob deb ntawm qhov siv dav tshaj plaws, qhov kev tshwm sim ntev tshaj plaws hauv keeb kwm, thiab hauv kev ua lag luam tam sim no kuj yog qhov pheej yig tshaj, yog li ntsuab siv los ntawm ntau tus neeg tsim khoom raws li cov xim tseem ceeb ntawm lawv cov khoom.
- 2, nyob rau hauv ib txwm muaj xwm txheej, tag nrho cov khoom PCB pawg thawj coj saib nyob rau hauv cov txheej txheem ntau lawm yog mus los ntawm lub rooj tsavxwm thiab SMT txheej txheem, nyob rau hauv lub rooj tsavxwm, muaj ntau yam txheej txheem yuav tsum mus los ntawm lub teeb daj chav tsev, vim hais tias cov nyhuv ntawm ntsuab nyob rau hauv lub daj. Lub teeb chav tsev zoo dua li lwm cov xim, tab sis qhov no tsis yog qhov laj thawj tseem ceeb.Thaum SMT vuam Cheebtsam, PCB mus rau lub solder muab tshuaj txhuam thiab muab tshuaj txhuam thiab qhov kawg AOI check teeb txheej txheem, cov txheej txheem no yog kawm kho qhov muag calibration, ntsuab keeb kwm yav dhau xim ntawm lub ntsuas ntsuas cov nyhuv yog zoo dua.
- 3.Cov xim PCB feem ntau yog xim liab, daj, ntsuab, xiav thiab dub.Txawm li cas los xij, vim yog cov txheej txheem tsim khoom thiab lwm yam teeb meem, cov txheej txheem tshuaj xyuas zoo ntawm ntau cov kab tseem yuav tsum tau tso siab rau cov neeg ua haujlwm kom pom thiab txheeb xyuas nrog lub qhov muag liab qab (qhov tseeb, feem ntau ntawm kev siv rab koob siv tshuab tam sim no).Nyob rau hauv cov ntaub ntawv ntawm lub teeb muaj zog, lub qhov muag ntsia rau ntawm lub rooj tsavxwm, uas yog ib tug heev qub Liu txoj kev ua hauj lwm, kuj hais lus, ntsuab yog qhov tsawg tshaj plaws teeb meem rau lub qhov muag, yog li feem ntau manufacturers ntawm lub khw yog siv ntsuab PCB.
- 4, lub hauv paus ntsiab lus ntawm xiav thiab dub yog tias lawv tau tov nrog cobalt thiab carbon teeb, nrog rau qee yam hluav taws xob conductivity, nyob rau hauv cov ntaub ntawv ntawm lub hwj chim yuav muaj teeb meem luv luv Circuit Court, thiab ntsuab PCB yog ib puag ncig tus phooj ywg, thaum siv nyob rau hauv. qhov kub thiab txias ib puag ncig, feem ntau yuav tsis tso cov pa phem.
- Thiab tseem muaj qee tus neeg tsim khoom lag luam hauv khw yuav siv lub rooj tsavxwm dub PCB, qhov laj thawj tseem ceeb uas Xiaobian ntseeg tias muaj ob qho laj thawj: ua ntej, nws zoo li high-end, thiab lub rooj tsavxwm dub tsis yooj yim pom cov xaim. , uas coj ib qho teeb meem rau lub tshuab luam ntawv.Dab tsi Xiaobian tau kawm yog tias feem ntau ntawm cov embedded boards ntawm Android yog tam sim no dub PCBS.
- 5, txog los ntawm nruab nrab thiab lig lub sij hawm ntawm lub xyoo pua xeem, kev lag luam tau pib them sai sai rau cov xim ntawm PCB board, feem ntau vim hais tias ntau high-end board hom thawj-kab manufacturers tau txais ntsuab PCB board xim tsim, yog li ntawd. tib neeg maj mam xav tias PCB xim ntsuab yuav tsum yog high-end.
