Muaj ntau yam micro, precision hluav taws xob Cheebtsam hauv SMT nti ua. Rau qhov kev ntseeg ntawm vuam ntawm cov khoom, nws yog ib qho nyuaj rau txiav txim nws qhov zoo ntawm qhov muag liab qab. Yog li ntawd, SMT nti ua kev lag luam los teeb tsa IQC department, nruj tswj xyuas cov khoom tuaj. Tiv thaiv cov txheej txheem tsim khoom lossis cov khoom tiav tiav, raws li SMT SMD kev ua haujlwm, peb yuav tsum paub tias lub ntsiab lus ntawm IQC tshuaj xyuas qhov tsis zoo. Dab tsi yog cov ntsiab lus ntawm IQC tshuaj xyuas, peb yuav tsum nkag siab meej! Cov hauv qab no rau koj los piav qhia txog IQC cov txheej txheem kev tshuaj xyuas tuaj.
I. SMT SMD processing defect txhais:
Ua ntej tshaj plaws, peb yuav tsum paub meej txog SMT SMD kev lag luam kev lag luam IQC tuaj xyuas qhov tsis xws luag hauv lub ntsiab lus ntawm dab tsi, kom peb ua tau zoo dua, tsim nyog, tsim nyog, txais cov khoom siv.
1. CR (kev puas tsuaj tuag): yog hais txog qhov muaj nyob ntawm cov khoom uas tuaj yeem ua rau tus kheej raug mob rau tus neeg tsim khoom lossis cov neeg siv, lossis cov khoom puas tsuaj uas yuav ua rau cov neeg siv khoom tsis txaus siab, nrog rau kev ua txhaum cai thiab kev tswj hwm ib puag ncig. (kev nyab xeeb / kev tiv thaiv ib puag ncig, thiab lwm yam)
2. MA (qhov tsis xws luag loj): Ib yam khoom ntawm cov khoom uas tsis ua raws li qhov yuav tsum tau ua (cov txheej txheem lossis kev ua haujlwm) lossis qhov tsis zoo ntawm cov tshuaj pleev ib ce loj.
3. MI (Minor Defect): Cov khoom muaj qee qhov tsis xws luag uas tsis cuam tshuam rau kev ua haujlwm thiab kev siv. (Feem ntau yog hais txog qhov tsis xws luag hauv qhov tsos).
II. SMT nti ua IQC tuaj xyuas cov ntsiab lus
Raws li SMT SMD ua lub voj voog ntau lawm luv dua, cov khoom siv tuaj yeem yog cov khoom siv sib xws, tom qab ntawd peb yuav tsum tsom mus rau kev ntsuam xyuas qhov sib xws ntawm cov khoom thiab BOM cov lus, pad oxidation, thauj khoom puas thiab lwm yam ntsiab lus. Feem ntau suav nrog kev txheeb xyuas cov ntaub ntawv thiab BOM lub rooj sib xws, seb qhov tsos ntawm cov xim tsis zoo thiab xim dub, txawm tias qhov vuam kawg ntawm oxidation, IC tus pin puas, seb puas muaj qhov deformation, seb puas muaj cov kab tawg, txawm tias hnub tas sij hawm thiab lwm yam ntsiab lus.
1. Txheeb xyuas seb cov PCB hom thiab BOM qhov yuav tsum tau ua puas zoo ib yam, seb lub ncoo oxidation discoloration, cov roj ntsuab puas lawm, seb cov ntawv luam tawm puas meej, seb nws puas tiaj tus, seb cov ces kaum puas yog qhov tshwm sim.
2. SMT chip processing resistor soj ntsuam specifications loj, tsis kam, nqi yuam kev thiab BOM cov lus yuav tsum tau. Kev tshuaj xyuas disc cim tus nqi thiab cov khoom siv lub cev silkscreen lo lus zoo ib yam, yog tias tsis muaj lo lus silkscreen yuav tsum siv tus choj LCR los ntsuas tus nqi tiv thaiv. Xyuas seb qhov vuam kawg puas yog oxidized thiab seb lub cev puas lawm.
3. SMT chip processing capacitor soj ntsuam specifications loj, capacitance, yuam kev, withstand voltage yog raws li qhov yuav tsum tau ntawm lub rooj BOM. Kev tshuaj xyuas disc qhia tus nqi thiab cov khoom siv lub cev silkscreen lo lus zoo ib yam, yog tias cov khoom siv ntau kuj yuav tsum tau siv tus choj LCR los ntsuas tus nqi capacitance zoo ib yam nrog lub logo. Xyuas seb qhov vuam kawg puas yog oxidized thiab seb lub cev puas lawm.
4. SMT chip processing inductor soj ntsuam specifications loj, paub tus nqi, yuam kev thiab BOM cov lus yuav tsum zoo ib yam. Txheeb xyuas tus nqi disc logo thiab cov khoom siv lub cev silkscreen lo lus zoo ib yam, yog tias tsis muaj lo lus silkscreen yuav tsum siv tus choj LCR los ntsuas tus nqi inductance. Xyuas seb qhov vuam kawg puas yog oxidized, seb lub cev puas lawm.
5. Diode, transistor test specifications loj, kev qhia thiab BOM cov lus yuav tsum tau zoo ib yam. Xyuas seb lub cim ntawm lub cev ntawm lo lus code thiab daim ntawv lo kom sib haum. Xyuas seb qhov vuam kawg puas yog oxidized, seb lub cev puas lawm.
6. IC, BGA Cheebtsam ntsuas qhov loj me, kev qhia thiab BOM cov lus xav tau zoo ib yam. Peak tshuaj xyuas lub cev ntawm qhov cim ntawm lo lus code nrog daim ntawv lo kom sib haum. Kev soj ntsuam tus pins, solder pob txawm tias oxidation, tus pin deformation.
7. Cov khoom sib txuas, cov nyees khawm thiab lwm yam khoom siv los xyuas seb qhov kev qhia tshwj xeeb loj thiab BOM cov lus xav tau zoo ib yam. Xyuas seb qhov vuam kawg puas yog oxidized, seb lub cev puas yog deformed. Xyuas seb qhov kub tsis kam mus txog qhov reflow soldering yuav tsum tau.
Zhejiang NeoDen Technology Co., LTD., nrhiav tau nyob rau hauv 2010, yog ib tug kws chaw tsim tshuaj paus tshwj xeeb nyob rau hauv SMT xaiv thiab qhov chaw tshuab, reflow cub, stencil printing tshuab, SMT ntau lawm kab thiab lwm yam SMT khoom. Peb muaj peb tus kheej R & D pab neeg thiab tus kheej lub Hoobkas, ua kom zoo dua ntawm peb tus kheej nplua nuj kev paub R & D, kev cob qhia zoo, tau txais lub koob npe nrov los ntawm cov neeg siv khoom thoob ntiaj teb.
