Cov Txheej Txheem Tseem Ceeb Ntawm PCBA Xeem Yog Dab Tsi?
Apr 09, 2021
Kev kuaj PCBA yog hais txog qhov kev xeem ntawm PCBA lub rooj tsavxwm rau IC lub cajmeem, lub rooj sib txig sib luag, tam sim no, qhov ntsuas voltage, thiab siab. Kev ntsuam xyuas PCBA yog qhov tsim nyog txuas rau nruj tswj hwm qhov zoo ntawm cov khoom xa tuaj, vim PCBA muaj ntau yam tsis tuaj yeem hauv cov txheej txheem ntau lawm, thiab nws yog qhov nyuaj los xyuas kom meej tias PCBA ntau lawm tiav thiab yog ib yam khoom zoo. Tom ntej no, Kuv yuav qhia cov txheej txheem tseem ceeb ntawm PCBA xeem.
Tests Cov kev xeem dab tsi raug muab xam nrog rau hauv PCBA kuaj?
Raws li cov khoom sib txawv thiab cov neeg siv khoom sib txawv, PCBA kuaj yuav sib txawv. Feem ntau, kev ntsuam xyuas PCBA feem ntau suav nrog kev ntsuam xyuas ICT online, FCT kuaj kev ua haujlwm, thiab kev kuaj kev laus.
Thib ob, cov txheej txheem ntawm PCBA xeem
Kev ntsuam xyuas PCBA feem ntau txhim kho ib qho kev xeem tshwj xeeb raws li cov neeg siv khoom' Cov txheej txheem kev xeem PCBA pib muaj raws li hauv qab no:
Qhov kev zov me nyuam kub → Qhov ntsuas ICT → Kev ntsuas FCT → kev kuaj kev laus
1. Qhov kev zov me nyuam hlawv
Tom qab lub PCBA board tiav cov vuam txheej txheem ntawm lub hauv ntej kawg, tus kws ua choj pib hlawv cov haujlwm ntawm tib lub tshuab computer hauv PCBA lub rooj tsavxwm, kom tib lub tshuab hluav taws xob ib leeg tuaj yeem paub cov haujlwm tshwj xeeb.
2. Qhov ntsuas ntawm ICT
Qhov ntsuas ntsuas ntawm ICT feem ntau siv cov ntawv ntsuas kev sib tw mus rau qhov kev sib tw ntawm PCBA kom paub qhov ntsuas ntawm PCBA Circuit Court qhib Circuit Court, luv Circuit Court thiab vuam mob ntawm cov khoom siv hluav taws xob. Qhov tseeb ntawm qhov ntsuas ntawm ICT yog qhov siab heev, cov lus qhia tau meej meej, thiab qhov tseem ceeb ntawm kev siv yog qhov dav.
3. Kev xeem FCT
FCT xeem tuaj yeem ntsuas cov ib puag ncig, tam sim no, voltage, siab thiab lwm yam kev ntsuas ntawm PCBA. Cov ntsiab lus ntawm cov ntawv xeem yog qhov sib txawv, uas tuaj yeem ua kom paub tias ntau yam sib txawv ntawm PCBA pawg thawj coj ua tau raws li cov qauv tsim ntawm tus tsim qauv.
4. Kev kuaj kev laus
Kev kuaj kev laus tuaj yeem ua kom muaj kev ruaj khov ntawm cov khoom los ntawm kev txuas ntxiv rau lub zog PCBA pawg thawj coj saib, simulating tus neeg siv' s siv thaj chaw, kuaj pom qee qhov tsis yooj yim-nrhiav tau qhov tsis xws luag, thiab tshuaj xyuas lub neej kev pab cuam ntawm cov khoom.
Tom qab PCBA dhau ntawm PCBA qhov kev xeem ntau dhau, PCBA lub rooj tsavxwm tsis muaj teeb meem tuaj yeem tau nrog cov ntawv sau uas tsim nyog, thiab thaum kawg nws tuaj yeem ntim thiab xa khoom.
