Cov txheej txheem kev tshawb nrhiav pom ntawm PCB board yog raws li hauv qab no:
1, PCB pawg thawj coj saib xyuas kev pom
Siv lub iav magnifying lossis calibrated microscope, tus neeg teb xov tooj qhov kev tshuaj xyuas qhov muag yog txoj kev tshuaj ntsuam xyuas feem ntau los txiav txim seb lub rooj tsav xwm puas haum thiab thaum twg yuav tsum tau kho cov haujlwm. Nws cov txiaj ntsig tseem ceeb yog tus nqi qis dua thiab tsis muaj qhov kev sim ntsuas, thaum nws qhov tsis zoo tseem ceeb yog tib neeg kev ua yuam kev, tus nqi siab ntev, kev kuaj xyuas tsis tu ncua, cov ntaub ntawv khaws cov teeb meem, thiab lwm yam. Tam sim no, vim qhov nce hauv PCB ntau lawm, txo qis. ntawm cov xaim sib nrug thiab cov khoom ntim ntawm PCB, txoj kev no tau dhau los ua ntau thiab tsis zoo.
2, PCB board kuaj online
Los ntawm kev tshawb nrhiav cov khoom siv hluav taws xob kom paub txog qhov kev tsim khoom tsis raug thiab kuaj cov analog, digital thiab cov teeb liab sib xyaw kom ntseeg tau tias lawv ua tau raws li cov lus qhia tshwj xeeb, muaj ntau txoj hauv kev xws li rab koob txaj tester thiab rab koob ya davhlau tester. Cov txiaj ntsig tseem ceeb yog cov nqi ntsuas qis rau ib lub rooj tsavxwm, muaj zog digital thiab kev ua haujlwm muaj peev xwm ua tau zoo, ceev thiab meej luv luv thiab qhib Circuit Court kuaj, programming firmware, siab tsis zoo thiab yooj yim ntawm programming. Lub ntsiab qhov tsis zoo yog qhov yuav tsum tau kuaj lub clamp, lub programming thiab debugging lub sij hawm, tus nqi ntawm kev ua lub fixture yog siab, thiab qhov nyuaj ntawm kev siv yog loj.
3, PCB board ua haujlwm kuaj
Kev ntsuas kev ua haujlwm yog siv cov cuab yeej ntsuas tshwj xeeb hauv nruab nrab theem thiab kawg ntawm cov kab ntau lawm kom ua tiav cov kev sim ua haujlwm ntawm lub rooj tsav xwm Circuit Court kom paub meej tias qhov zoo ntawm lub rooj tsav xwm hauv Circuit Court. Kev ntsuas kev ua haujlwm tuaj yeem hais tau tias yog qhov kev xeem tsis siv neeg ua ntej tshaj plaws, uas yog raws li lub rooj tsav xwm tshwj xeeb lossis ib chav tsev tshwj xeeb thiab tuaj yeem ua tiav los ntawm ntau yam khoom siv. Muaj ntau hom kev xeem cov khoom kawg, cov qauv khoom siv tshiab kawg, thiab kev sib tw ua ke. Kev ntsuas kev ua haujlwm feem ntau tsis muab cov ntaub ntawv sib sib zog nqus xws li tus pin thiab qib kev kuaj mob rau cov txheej txheem hloov kho, thiab yuav tsum muaj cov cuab yeej tshwj xeeb thiab cov txheej txheem kuaj tshwj xeeb. Kev sau cov txheej txheem kev sim ua haujlwm yog qhov nyuaj thiab yog li tsis haum rau feem ntau cov kab ntau lawm.
4, tsis siv neeg kho qhov muag pom
Kuj tseem hu ua kev tshuaj xyuas tsis siv neeg pom, yog raws li lub hauv paus ntsiab lus kho qhov muag, kev siv cov duab tsom xam, khoos phis tawj thiab kev tswj hwm tsis siv neeg thiab lwm yam thev naus laus zis, cov teeb meem uas tau ntsib hauv kev tsim khoom rau kev tshawb nrhiav thiab kev ua haujlwm, yog ib txoj hauv kev tshiab kom paub meej txog kev tsim khoom tsis xws luag. AOI feem ntau yog siv ua ntej thiab tom qab reflow, ua ntej kev ntsuam xyuas hluav taws xob, txhawm rau txhim kho qhov kev lees paub thaum lub sij hawm kho hluav taws xob lossis kev sim ua haujlwm, thaum tus nqi kho qhov tsis xws luag qis dua tus nqi tom qab qhov kev xeem zaum kawg, feem ntau mus txog kaum zaug.
5, tsis siv neeg X-ray kuaj
Siv qhov sib txawv absorptivity ntawm cov khoom sib txawv rau X-ray, peb tuaj yeem pom los ntawm qhov chaw uas yuav tsum tau kuaj thiab pom qhov tsis xws luag. Nws yog tsuas yog siv los kuaj ultra-nplua suab thiab tsis zoo li cov choj hluav taws xob, thiab tseem tuaj yeem tshawb pom sab hauv cov khoom siv hauv ICCOn siv thev naus laus zis. Tam sim no nws yog tib txoj kev los ntsuas qhov vuam zoo ntawm lub pob kab sib chaws thiab cov khoom tiv thaiv tin. Qhov zoo tshaj plaws yog lub peev xwm los kuaj xyuas BGA vuam zoo thiab cov khoom sib txuas, tsis muaj nqi kho; Lub ntsiab tsis zoo yog qeeb ceev, siab tsis ua hauj lwm tus nqi, teeb meem nyob rau hauv kev soj ntsuam reworked solder pob qij txha, tus nqi siab, thiab ntev kev pab cuam lub sij hawm tsim kho, uas yog ib tug kuj tshiab nrhiav kom tau txoj kev thiab yuav tsum tau mus kawm ntxiv.
6, laser ntes system
Nws yog qhov kev txhim kho tshiab tshaj plaws hauv PCB kuaj tshuab. Nws siv lub laser beam los luam theej duab lub rooj tsavxwm, sau tag nrho cov ntaub ntawv ntsuas, thiab sib piv cov nqi ntsuas qhov tseeb nrog rau qhov preset tsim nyog txwv tus nqi. Cov tshuab no tau raug pov thawj ntawm cov phaj teeb, raug txiav txim siab rau kev sib dhos phaj kuaj, thiab ceev txaus rau cov kab ntau lawm. Cov zis tawm sai, tsis muaj qhov yuav tsum tau ua thiab qhov muag tsis pom kev nkag mus yog nws qhov txiaj ntsig tseem ceeb; Tus nqi pib siab, txij nkawm thiab siv cov teeb meem yog nws qhov tsis txaus.
7, kuaj qhov loj me
Qhov ntev ntawm qhov txoj hauj lwm, qhov ntev thiab qhov dav, thiab txoj hauj lwm degree yog ntsuas los ntawm cov cuab yeej ntsuas quadratic. Txij li thaum PCB yog ib yam khoom me me, nyias thiab mos, qhov kev ntsuas kev sib cuag yog ib qho yooj yim los tsim deformation, uas ua rau qhov ntsuas tsis raug, thiab cov cuab yeej ntsuas ob-dimensional tau dhau los ua qhov zoo tshaj plaws high-precision dimensional ntsuas ntsuas. Tom qab cov duab ntsuas ntsuas ntawm Sirui ntsuas yog programmed, nws tuaj yeem paub qhov ntsuas tsis siv neeg, uas tsis tsuas yog muaj qhov ntsuas qhov tseeb, tab sis kuj tseem txo qis lub sijhawm ntsuas thiab txhim kho qhov ntsuas ntsuas.
