PCBA Board Testingyog ib kauj ruam tseem ceeb kom paub meej tias qhov zoo, high-reliability pcba cov khoom lag luam raug xa tawm rau cov neeg siv khoom, thiab zam kev tsis taus tom qab muag. Hauv qab no yog ntau txoj hauv kev ntawm PCBA Board sim tshuaj:
- Kev kuaj pom, kuaj pom yog saib nws manually. Kev kuaj ntawm PCBA Los Ua Ke yog cov txheej txheem txheej txheem tshaj plaws hauv PCBA zoo tshuaj ntsuam. Tsuas yog siv lub qhov muag thiab lub khob iav kom loj dua los tshawb xyuas qhov Circuit Court ntawm PCBA Board thiab solding ntawm cov hluav taws xob hauv hluav taws xob kom pom tias muaj ib lub ntxa. , Txawm tias cov txuas hniav, ntxiv rau cov pob qij txha sib txuas, puas yog tus ntaus pob qij txha yog cov pob qij txha, seb puas muaj qhov sib dhos tsis tau zoo thiab ua tsis tiav soldering. Thiab kev sib koom tes nrog lub khob loj kom ntes pcba
- In Inf-Circuit Sacerer (ICT) ICT tuaj yeem txheeb xyuas cov teeb meem thiab cov teeb meem sib xyaw hauv PCBA. Nws muaj kev kub ceev, siab ruaj khov, kuaj xyuas luv luv, qhib Circuit Court, Kuj, capacitance.
- Tsis siv neeg kho qhov muag (AOI) Kev sib raug zoo kom pom tau muaj offline thiab online, thiab muaj qhov sib txawv ntawm 2D thiab 3D. Tam sim no, AOI yog nrov dua hauv lub Hoobkas thaj. AOI siv kev pom zoo cov yees duab los tshawb xyuas tag nrho cov PCBA Board thiab siv nws. Lub tshuab ntsuas cov ntaub ntawv yog siv los txiav txim siab qhov zoo ntawm PCBA board vuam. Lub koob yees duab tau scans cov khoom tsis xws luag ntawm PCBA Board nyob rau hauv kev xeem. Ua ntej kev xeem, nws yog qhov tsim nyog los txiav txim siab ua cov ntaub ntawv OK, thiab khaws cov ntaub ntawv ntawm OK pawg thawj coj hauv AOI. Tom ntej loj ntau lawm yog ua raws li no OK Board. Ua tus qauv yooj yim los txiav txim siab seb puas muaj lwm cov laug cam tsis ua li cas.
- X-ray tshuab (xoo hluav taws xob) rau hluav taws xob sib xyaw xws li BGA / QFP, ICT thiab AOI tsis tuaj yeem pom tau qhov zoo ntawm lawv cov pins hauv sab hauv. X-duab tshav yog zoo ib yam li lub tshuab xoo hluav taws xob hauv siab, uas tuaj yeem hla cov pins hauv pcb los saib seb puas muaj kev tso cai, lwm yam. X-tshav dav siv nyob rau hauv cov khoom uas muaj kev ntseeg siab rau kev pab cuam lub zog aviation, Automotive Electronics
- Kev kuaj xyuas ua ntej pawg neeg ntau lawm thiab kev sib dhos, kev soj ntsuam thawj zaug tau ua rau muaj teeb meem hauv cov laug cam kev kuaj xyuas, uas yog hu ua thawj zaug kuaj.
- Cov kev sojntsuam ya ntawm Flying Sojntsuam Sojntsuam yog tsim nyog rau kev tshuaj xyuas ntawm cov nqi tshuaj tshaj tawm uas xav tau cov nqi tshuaj xyuas kim. Tus qauv tsim thiab tshuaj xyuas ntawm cov kev sojntsuam ya tuaj yeem ua tiav hauv ib hnub, thiab cov kev sib dhos ua ke yog tsawg. Nws muaj peev xwm tshawb xyuas rau qhib, luv thiab kev qhia ntawm cov khoom siv ntawm PCB. Tsis tas li, nws ua haujlwm tau zoo rau kev txheeb xyuas cov qauv sib txuas thiab cov kev sib ncag.
- Kev tsim khoom tsis xws luag (MDA) Lub hom phiaj ntawm MDA tsuas yog mus nrhiav kev kuaj cov txwj laus los qhia cov khoom lag luam nthuav tawm. Txij li feem ntau manufacturg tej yam yog yooj yim kev sib txuas teeb meem, MDA tsuas yog txwv rau kev ntsuas txuas ntxiv. Feem ntau, tus tester yuav muaj peev xwm kuaj pom qhov muaj peev xwm ntawm cov khoom siv, capacitors, thiab transistors. Kev kuaj pom ntawm cov khoom sib xyaw ua ke tuaj yeem ua tiav siv kev tiv thaiv diodes los qhia kom muaj kev tso chaw zoo.
- Kev kuaj mob laus. Tom qab PCBA tau undergone mounting thiab dip posting, sub-surchecting, tom qab kev sim ua ntej, tom qab kev ua haujlwm ua ntej yog ib txwm muaj, thiab lwm yam.
