PCBA board kuajyog ib kauj ruam tseem ceeb los xyuas kom meej tias cov khoom zoo, kev ruaj ntseg zoo, thiab kev ntseeg siab PCBA cov khoom raug xa mus rau cov neeg siv khoom, txo qhov tsis xws luag hauv tes ntawm cov neeg siv khoom, thiab zam kev muag khoom tom qab muag. Hauv qab no yog ob peb txoj hauv kev ntawm PCBA board kuaj:
- Kev kuaj pom pom, Kev kuaj pom pom yog saib nws manually. Kev soj ntsuam pom ntawm PCBA sib dhos yog txoj hauv kev tseem ceeb tshaj plaws hauv PCBA kev tshuaj xyuas zoo. Tsuas yog siv ob lub qhov muag thiab lub iav tsom iav los xyuas qhov Circuit Court ntawm PCBA board thiab cov khoom siv hluav taws xob los xyuas seb puas muaj lub qhov ntxa. , Txawm tias txuas hniav, ntau tin, seb puas yog cov pob qij txha solder, seb puas muaj tsawg dua thiab tsis tiav soldering. Thiab koom tes nrog cov iav tsom iav kom pom PCBA
- Hauv-Circuit Tester (ICT) ICT tuaj yeem txheeb xyuas cov teeb meem ntawm cov khoom siv hauv PCBA. Nws muaj kev kub ceev, siab stability, xyuas luv luv Circuit Court, qhib Circuit Court, kuj, capacitance.
- Tsis siv neeg kho qhov muag tshuaj ntsuam xyuas (AOI) tsis siv neeg kev sib raug zoo nrhiav tau offline thiab online, thiab kuj muaj qhov sib txawv ntawm 2D thiab 3D. Tam sim no, AOI yog nrov dua nyob rau hauv lub Hoobkas thaj. AOI siv lub koob yees duab lees paub los luam theej duab tag nrho PCBA pawg thawj coj saib thiab rov siv nws dua. Lub tshuab cov ntaub ntawv txheeb xyuas yog siv los txiav txim siab qhov zoo ntawm PCBA board vuam. Lub koob yees duab cia li txheeb xyuas qhov tsis zoo ntawm PCBA pawg thawj coj saib hauv kev sim. Ua ntej kev sim, nws yog ib qho tsim nyog los txiav txim siab OK board, thiab khaws cov ntaub ntawv ntawm OK board hauv AOI. Kev tsim khoom loj tom qab yog ua raws li OK board. Ua ib qho qauv yooj yim los txiav txim seb lwm cov boards puas zoo.
- X-ray tshuab (X-RAY) Rau cov khoom siv hluav taws xob xws li BGA / QFP, ICT thiab AOI tsis tuaj yeem kuaj xyuas qhov zoo ntawm lawv cov pins sab hauv. X-RAY zoo ib yam li lub hauv siab X-ray tshuab, uas tuaj yeem dhau los ntawm Kos lub PCB nto kom pom tias cov khoom siv ntawm cov pins sab hauv yog soldered, seb qhov chaw nyob hauv qhov chaw, thiab lwm yam. X-RAY siv X-rays nkag mus. PCB board saib sab hauv. X-RAY yog dav siv nyob rau hauv cov khoom uas muaj kev ntseeg siab, zoo ib yam li aviation Electronics, automotive electronics
- Kev soj ntsuam kuaj ua ntej ntau lawm thiab kev sib sau ua ke, thawj cov qauv tshuaj xyuas feem ntau yog ua tiav, yog li cov teeb meem ntawm cov teeb meem tsis zoo tuaj yeem zam tau hauv kev tsim khoom loj, uas ua rau muaj teeb meem hauv kev tsim cov PCBA boards, uas yog hu ua thawj kev tshuaj xyuas.
- Kev sojntsuam ya ntawm lub davhlau ya davhlau tester yog tsim rau kev soj ntsuam ntawm high-complexity PCBs uas yuav tsum tau kim nqi tshuaj xyuas. Kev tsim thiab kev soj ntsuam ntawm lub davhlau ya nyob twg tuaj yeem ua tiav nyob rau hauv ib hnub, thiab cov nqi sib dhos yog qhov tsawg. Nws muaj peev xwm txheeb xyuas qhov qhib, luv thiab kev taw qhia ntawm cov khoom txuas rau ntawm PCB. Tsis tas li ntawd, nws ua haujlwm zoo rau kev txheeb xyuas cov txheej txheem thiab kev sib dhos.
- Manufacturing Defect Analyzer (MDA) Lub hom phiaj ntawm MDA tsuas yog ua kom pom lub ntsej muag kuaj lub rooj tsavxwm kom nthuav tawm cov khoom tsis xws luag. Txij li feem ntau kev tsim khoom tsis raug yog cov teeb meem kev sib txuas yooj yim, MDA tsuas yog ntsuas kev txuas ntxiv. Feem ntau, tus tester yuav tuaj yeem kuaj pom muaj cov resistors, capacitors, thiab transistors. Kev tshawb pom ntawm kev sib xyaw ua ke kuj tuaj yeem ua tiav siv kev tiv thaiv diodes los qhia qhov kev tso kawm kom raug.
- Kev kuaj kev laus. Tom qab lub PCBA tau dhau los ua haujlwm thiab DIP tom qab soldering, sub-board trimming, kev tshuaj xyuas saum npoo thiab kev sim thawj zaug, tom qab kev tsim khoom loj tiav lawm, PCBA pawg thawj coj yuav raug kuaj rau kev laus los kuaj seb txhua qhov haujlwm zoo li cas, cov khoom siv hluav taws xob yog qhov qub, thiab lwm yam.
