Dab tsi yog cov txheej txheem rov ua haujlwm ntawm kev lees paub tus ntiv tes hloov tau yooj yim thiab nruj

Hauv kev lees paub tus ntiv tes Rigid-flex PCB cov txheej txheem tsim khoom, kev ua haujlwm rov ua dua yog txheej txheem tsis meej tab sis tseem ceeb heev. Ntau tus ntiv tes lees paub Rigid-flex PCBs nrog cov khoom tsis zoo tau "reborn" los ntawm kev rov ua haujlwm hauv cov txheej txheem tsim khoom no thiab dhau los ua cov khoom tsim nyog. Niaj hnub no, peb yuav piav qhia txog cov txheej txheem rov ua haujlwm hauv kev lees paub tus ntiv tes Rigid-flex PCB txheej txheem tsim khoom kom ntxaws.

1. Lub hom phiaj ntawm kev paub cov ntiv tes Rigid-flex PCB rework

(1) Nyob rau hauv tus txheej txheem ntawm reflow soldering thiab yoj soldering, tsis xws luag xws li qhib Circuit Court, bridging, virtual soldering thiab tsis zoo wetting yuav tsum tau kho manually nrog kev pab los ntawm tej yam cuab yeej kom ua tiav cov nyhuv ntawm kev tshem tawm ntau yam solder joint defects, yog li ntawd. Raws li kom tau txais Kev Tsim Nyog Cov Ntaub Ntawv txheeb xyuas cov pob qij txha ntawm Rigid-flex PCB.

(2) Kho vuam rau cov khoom uas ploj lawm.

(3) Hloov cov khoom tsis raug thiab cov khoom puas.

(4) Tom qab ib lub rooj tsavxwm thiab tag nrho lub tshuab yog debugged, hloov cov khoom tsis tsim nyog.

(5) Kev lees paub tus ntiv tes Rigid-flex PCB tshuab yuav tsum tau kho yog tias pom muaj teeb meem tom qab tawm hauv lub hoobkas.

2. Txheeb xyuas cov pob qij txha uas yuav tsum tau kho

(1) Muab tso rau hauv cov khoom siv hluav taws xob

Txhawm rau txiav txim siab seb cov pob qij txha yuav tsum tau kho li cas, koj yuav tsum xub nrhiav cov khoom siv hluav taws xob thiab txiav txim siab seb cov khoom siv hluav taws xob twg yog nyob rau theem twg. Qib 3 yog qhov xav tau siab tshaj plaws. Yog tias cov khoom muaj nyob rau qib 3, nws yuav tsum tau kuaj raws li tus qauv siab tshaj plaws; yog tias cov khoom yog nyob rau theem 1, nws tuaj yeem raug kuaj raws li tus qauv qis tshaj.

(2) Kom paub meej lub ntsiab lus ntawm "zoo solder pob qij txha"

Cov pob qij txha zoo heev hais txog cov pob qij txha uas muaj peev xwm tswj tau cov khoom siv hluav taws xob thiab kev siv lub zog thaum lub sij hawm siv ib puag ncig, txoj kev thiab lub neej lub sij hawm txiav txim siab thaum tsim cov khoom siv hluav taws xob; ntev npaum li qhov xwm txheej no tau ntsib, tsis tas yuav rov ua haujlwm dua.

(3) Ntsuas nrog tus qauv IPC-A610E. Tsis tas yuav rov ua haujlwm dua yog tias muaj cov xwm txheej rau qib 1 thiab 2 tau ua tiav.

(4) Pom tau los ntawm tus qauv IPC-A610E, cov qib 1, 2, thiab 3 tsis raug yuav tsum tau kho.

(5) Siv tus qauv IPC-A610E rau kev sim, thiab cov txheej txheem ceeb toom tias Qib 1 thiab 2 yuav tsum tau kho.

Nco tseg: Txheej Txheem Ceeb Toom 3 txhais tau hais tias nws muaj kev nyab xeeb siv txawm tias muaj cov xwm txheej tsis ua raws. Yog li, feem ntau, cov txheej txheem ceeb toom theem 3 tuaj yeem kho tau raws li qib 1, thiab tsis tas yuav rov qab kho.

3. Kev ceev faj rau kev kho

(1) Tsis txhob ua kom cov pawm puas.

(2) Ua kom ntseeg tau tias siv tau ntawm cov khoom siv. Yog hais tias nws yog ob-sided welding tivthaiv, ib qho kev tivthaiv yuav tsum tau rhuab ob zaug; yog tias nws tau kho ib zaug ua ntej tawm hauv lub Hoobkas, nws yuav tsum tau muab cua sov ob zaug; yog tias nws tau kho ib zaug tom qab tawm hauv lub Hoobkas, nws yuav tsum tau muab cua sov ob zaug. Raws li qhov kev suav no, ib feem yuav tsum muaj peev xwm tiv taus 6 qhov kub thiab txias soldering yuav suav tau tias yog cov khoom tsim nyog. Rau cov khoom lag luam muaj kev ntseeg siab, cov khoom uas tau kho ib zaug yuav tsis siv lawm, txwv tsis pub muaj teeb meem kev ntseeg siab yuav tshwm sim.

(3) Qhov saum npoo ntawm cov khoom tivthaiv thiab qhov chaw ntawm cov ntiv tes lees paub muag muag thiab tawv ua ke yuav tsum tau khaws cia ncaj.

(4) Cov txheej txheem tsis ua haujlwm hauv kev tsim khoom yuav tsum tau simulated kom ntau li ntau tau.

(5) Ua tib zoo saib xyuas qhov muaj peev xwm ntawm cov hluav taws xob hluav taws xob hluav taws xob, thiab ua haujlwm raws li qhov tseeb vuam nkhaus thaum kho.
