Flying Probe Test thiab Test Jig yog ob txoj kev siv dav hauv kev ntsuam xyuas cov khoom siv hluav taws xob thiab cov ntawv luam tawm Circuit Board (PCBs). Txawm hais tias sib koom lub hom phiaj ntawm kev ua kom pom kev ua haujlwm zoo thiab kev ntseeg tau, cov txheej txheem no nthuav tawm cov yam ntxwv tshwj xeeb. Cia peb nkag siab txog qhov tsis sib xws ntawm Flying Probe Test thiab Test Jig ua ke!
Nkag siab txog Cov Txheej Txheem
Flying Probe Testing, tseem hu ua flying probe technology, encompasses ib tug automated txheej txheem tsim los tshuaj xyuas cov hluav taws xob sib txuas thiab kev ua tau zoo ntawm PCBs. Txoj kev no ntiav cov cuab yeej tshwj xeeb hu ua flying probe testers, featuring multimovable probes uas tsim kev sib cuag nrog PCB's circuitry los ntsuas ntau yam hluav taws xob tsis.
Ntawm qhov tod tes, Test Jig, lwm yam hu ua test fixture lossis test bed, sawv cev rau kev teeb tsa kho vajtse uas siv los kuaj PCBs lossis cov khoom siv hluav taws xob. Nws sawv ua ib txoj kev sim ntau dua thiab sib txawv piv rau Flying Probe Testing. Ib qho kev xeem jig suav nrog cov khoom sib txuas, cov khoom sib txuas, cov ntsiab lus xeem, thiab lwm yam khoom tseem ceeb rau kev sib txuas nrog PCB raug sim.
Lub hom phiaj thiab kev siv tau
Ob qhov Flying Probe Test thiab Test Jig ua qhov kev sim ua tau zoo rau cov pawg thawj coj saib xyuas. Txawm li cas los xij, lawv txoj kev siv yog nyob ntawm cov xwm txheej tshwj xeeb thiab cov kev xav tau. Cia peb tshawb txog lub hom phiaj thiab kev siv tau ntawm txhua tus:
Flying Probe Test: Txoj kev no pom nws cov niche hauv cov khoom ntim qis, kev ntsuas tus qauv, lossis qhov xwm txheej uas tus nqi thiab lub sijhawm cuam tshuam nrog kev tsim cov ntawv xeem jig tsis zoo. Nws muaj qhov zoo ntawm kev yoog raws thiab yoog raws, ua kom muaj ntau yam PCB tsim yam tsis tas yuav tsum muaj kev tsim kho thiab tsim khoom.
Kuaj Jig: Feem ntau ua haujlwm nyob rau hauv cov xwm txheej ntau lawm, Test Jig ci thaum qhov kev sim zoo ib yam thiab rov ua dua yog qhov tseem ceeb. Nws ua pov thawj tsim nyog thaum txhua lub rooj tsavxwm xav tau qhov tseeb thiab kev ntsuas raws li cov kev xav tau tshwj xeeb. Test Jig xav tau kev nqis peev ua ntej hauv kev tsim thiab kev tsim kho ntawm qhov kev sim siab.
Qhov Tseem Ceeb
Thaum ob qho tib si Flying Probe Test thiab Test Jig qhia lub hom phiaj ntawm kev lees paub PCB zoo thiab kev ua haujlwm, qhov sib txawv tseem ceeb ntawm ob txoj kev tshwm sim. Cov kev sib txawv no ua lub luag haujlwm tseem ceeb hauv kev xaiv qhov kev ntsuam xyuas tsim nyog raws li ntau yam. Cia peb tshawb nrhiav qhov tsis sib xws:
l Kev Xeem Ceev
Flying probe testers tuaj yeem pom qhov kev sim qeeb qeeb, tshwj xeeb tshaj yog thaum cuam tshuam nrog ntau dua ntawm cov ntsiab lus ntawm PCB. Txawm li cas los xij, lawv them nyiaj nrog kev teeb tsa sai thiab yoog raws cov qauv PCB sib txawv, tshem tawm qhov xav tau ntawm kev hloov kho. Hloov pauv, Test Jig xeem feem ntau ua haujlwm ntawm qhov nrawm dua, feem ntau muaj peev xwm ua ntau pua qhov kev xeem hauv ib teev. Thaum lub fixture raug teeb tsa thiab ua kom zoo, cov txheej txheem kev sim ua tau zoo heev, ua rau nws tsim nyog rau qhov chaw tsim khoom loj.
l Nqi thiab sij hawm txiav txim siab
Flying Probe Test ua pov thawj los ua tus nqi-zoo thiab kev xaiv lub sijhawm zoo piv rau Test Jig xeem. Nws tshem tawm qhov xav tau ntawm kev tsim kho, tsim khoom, thiab teeb tsa lub sijhawm, ua rau nws siv tau rau kev hloov pauv sai thiab cov xwm txheej tsis txaus ntseeg. Hloov pauv, Test Jig xeem yuav tsum tau nqis peev ua ntej hauv kev tsim thiab tsim kho qhov kev sim siab. Tus nqi cuam tshuam thiab lub sijhawm rau kev tsim kho thiab tsim khoom yuav tsum tau txiav txim siab, tshwj xeeb tshaj yog rau cov khoom siv me me lossis cov qauv tsim.
l Fault Tolerance
Flying Probe Test tsis muab kev lees paub ntawm 100% kev ua txhaum cai, vim tias muaj qhov ua tau ntawm qhov yuam kev me me, feem ntau nyob ib puag ncig 1%. Qee qhov yuam kev yuav mus nrhiav tsis tau los ntawm kev sojntsuam ya ya. Hloov pauv, Test Jig muaj qib siab dua ntawm kev ua txhaum cai thiab ua kom 100% cov txiaj ntsig kev xeem. Lub xub ntiag ntawm ib tug tshwj xeeb fixture thiab taag hluav taws xob kev twb kev txuas pab rau ib tug ntau txhim khu kev qha kev xeem txheej txheem.
Hauv cov ntsiab lus, Flying Probe Test thiab Test Jig yog cov txheej txheem sib txawv ua haujlwm hauv kev sim cov khoom siv hluav taws xob thiab PCBs. Txawm hais tias ob qho tib si txoj hauv kev los xyuas kom meej kev ua haujlwm thiab kev ntseeg siab, lawv sib txawv ntawm qhov kev ntsuas ceev, kev txiav txim siab nqi, thiab kev ua txhaum cai. Kev xaiv ntawm Flying Probe Test thiab Test Jig nyob ntawm ntau yam. Los ntawm ua tib zoo soj ntsuam cov xwm txheej no, koj tuaj yeem txiav txim siab paub txog txoj kev sim uas tsim nyog tshaj plaws rau koj cov kev xav tau PCB tshwj xeeb.
