Tsev A, Qifeng Park, Lilang, Nanwan,X-RAY cov cuab yeej tshuaj xyuas ua haujlwm li cas?
Nrog rau kev txhim kho txuas ntxiv ntawm cov cuab yeej siv hluav taws xob, SMT thev naus laus zis tau dhau los ua neeg nyiam, qhov loj ntawm ib leeg-chip microcomputer nti tau txais me me thiab me me, thiab tus pin txoj hauj lwm ntawm ib-chip microcomputer nti kuj maj mam nce, tshwj xeeb tshaj yog cov BGA ib leeg-chip microcomputer nti. Txij li thaum BGA MCU nti tsis tau muab faib raws li cov qauv tsim tab sis tau muab faib rau hauv qab ntawm MCU nti, nws yog qhov tsis yooj yim sua kom txiav txim siab qhov zoo ntawm cov pob qij txha raws li kev tshuaj xyuas cov khoom siv dag zog, yog li nws yuav tsum tau sim raws li rau ICT thiab txawm ua haujlwm. Yog li ntawd, X-ray tshuaj xyuas tshuab yog ntau thiab ntau dav siv nyob rau hauv SMT post-reflow tshuaj xyuas. Nws tuaj yeem tsis tsuas yog ntsuas cov pob qij txha zoo nkaus xwb tab sis kuj kuaj xyuas thiab kho qhov tsis raug raws sijhawm.
Txhua qhov kev lag luam muaj qee qhov kev pab cuam. Hauv kev lag luam hluav taws xob, X-RAY cov cuab yeej kuaj xyuas yog ib qho ntawm lawv.
X-ray cov cuab yeej kuaj xyuas ua haujlwm li cas.
1. Ua ntej, X-RAY ntaus ntawv tsuas yog siv lub zog nkag ntawm X-rays. X-rays muaj luv wavelengths thiab siab zog. Thaum teeb meem irradiates ib yam khoom, nws tsuas yog nqus ib feem me me ntawm X-rays, thiab feem ntau ntawm lub zog ntawm X-rays yuav dhau los ntawm qhov khoob ntawm cov teeb meem atoms, uas qhia tias muaj zog nkag mus.
2. Cov khoom siv x-ray tuaj yeem kuaj xyuas qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv x-ray thiab qhov ntom ntom ntawm cov ntaub ntawv, thiab tuaj yeem paub qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv. Txoj kev no, yog tias cov khoom kuaj pom muaj cov thicknesses sib txawv, cov duab hloov pauv, sib txawv X-ray nqus thiab cov duab sib txawv, cov duab dub thiab dawb sib txawv yuav raug tsim.
3. tuaj yeem siv rau IGBT semiconductor kuaj, BGA nti kuaj, LED lub teeb bar kuaj, PCB liab qab board kuaj, lithium roj teeb kuaj, thiab tsis muaj kev puas tsuaj ntawm txhuas castings.
4. luv luv, siv lub microfocus x-ray ntaus ntawv uas tsis muaj kev cuam tshuam los ntawm cov duab zoo fluoroscopic, uas yog tom qab ntawd hloov mus rau lub teeb liab uas tau txais los ntawm lub tiaj tiaj tus ntes. Tag nrho cov haujlwm ntawm kev khiav hauj lwm software tuaj yeem ua tiav nrog tus nas, uas yooj yim siv. Cov txheej txheem kev ua haujlwm siab x-ray tuaj yeem kuaj pom qhov tsis xws luag mus txog 5 microns, qee cov khoom siv x-ray tuaj yeem kuaj pom qhov tsis xws luag hauv qab 2.5 microns, lub kaw lus tuaj yeem nthuav tawm 1000 zaug, thiab cov khoom tuaj yeem tig tau. X-ray cov cuab yeej tuaj yeem kuaj tau manually lossis txiav, thiab cov ntaub ntawv tshawb pom tuaj yeem raug tsim tawm.
X-ray thev naus laus zis tau hloov zuj zus los ntawm qhov chaw soj ntsuam 2D yav dhau los mus rau txoj kev tshuaj xyuas 3D tam sim no. Tus qub yog ib txoj kev ntsuas x-ray qhov tsis zoo, uas tuaj yeem tsim cov duab pom tseeb ntawm cov pob qij txha ntawm ib lub rooj tsavxwm, tab sis tam sim no feem ntau siv ob-sided reflow soldering board muaj qhov cuam tshuam tsis zoo, uas ua rau muaj kev sib tshooj ntawm cov khoom siv. pom cov duab ntawm ob lub pob qij txha, ua rau nws nyuaj rau kev paub qhov txawv. Txoj kev soj ntsuam tom kawg 3D siv cov txheej txheem txheej txheej, uas yog, tsom rau cov nqaj ntawm txhua txheej thiab ua kom pom cov duab sib thooj mus rau qhov siab ceev tig tau txais qhov chaw. Vim qhov kev sib hloov ntawm qhov chaw txais, cov duab ntawm qhov chaw sib tshuam yog qhov tseeb heev, cov duab ntawm lwm cov khaubncaws sab nraud povtseg raug tshem tawm, thiab kev tshuaj xyuas 3D tuaj yeem ua tus duab ntawm cov pob qij txha ntawm ob sab ntawm lub rooj tsavxwm.
3DX-duab tshav tshuab tuaj yeem tsis tsuas yog kuaj pom ob sab ntawm cov laug cam, tab sis kuj tseem pom tau ntau txheej duab cov duab ntawm cov pob qij txha tsis pom xws li BGA, uas yog, sab sauv, nruab nrab thiab qis daim duab ntawm BGA solder pob pob qij txha. Tsis tas li ntawd, txoj kev tseem tuaj yeem txheeb xyuas qhov los ntawm qhov ntawm PTH solder pob qij txha, thiab xyuas seb lub solder nyob rau hauv lub qhov yog txaus, uas zoo heev.
txhim kho kev sib txuas zoo ntawm cov pob qij txha.
Hloov ICT nrog X-ray.
Nrog rau kev nce ntawm cov txheej txheej ceev thiab qhov me me ntawm cov khoom siv, qhov chaw kuaj mob ICT tau txais me dua thiab me dua thaum tsim cov qauv txheej txheem. Thiab rau cov txheej txheem nyuaj, yog tias nws raug xa ncaj qha los ntawm SMT cov kab ntau lawm mus rau txoj haujlwm kuaj kev ua haujlwm, nws yuav tsis tsuas yog txo cov khoom tsim nyog tus nqi, tab sis kuj nce tus nqi ntawm kev kuaj xyuas qhov txhaum thiab kev saib xyuas ntawm lub rooj tsav xwm Circuit Court. Txawm hais tias kev xa khoom qeeb, hauv kev lag luam kev sib tw niaj hnub no, yog tias kev tshuaj xyuas ICT hloov los ntawm kev kuaj X-ray, qhov kev tsim khoom ntawm qhov kev sim ua haujlwm tuaj yeem lav tau. Tsis tas li ntawd, batch tshuaj xyuas siv X-ray hauv SMT ntau lawm tuaj yeem txo lossis txawm tias tshem tawm batch yuam kev.
Lub Scope ntawm kev siv lub X-RAY nrhiav kom tau ntaus ntawv.
1. Cov khoom siv kuaj X-RAY yog dav siv, thiab tuaj yeem siv rau hauv kev sim roj teeb lithium, ntim khoom semiconductor, automotive, circuit board assembly (PCBA) thiab lwm yam lag luam. Ntsuas txoj hauj lwm thiab cov duab ntawm cov khoom sab hauv tom qab ntim khoom, nrhiav cov teeb meem, paub meej tias cov khoom tsim nyog, thiab saib xyuas cov xwm txheej sab hauv.
2. Cov ntawv thov tshwj xeeb: feem ntau yog siv rau SMT.LED.BGA.CSP flip-chip tshuaj xyuas, semiconductor, ntim khoom, lithium roj teeb kev lag luam, cov khoom siv hluav taws xob, nws pib qhov chaw, kev lag luam photovoltaic, aluminium die-casting, molded plastics, ceramic khoom, lwm yam kev lag luam tshwj xeeb.
