Ib qho yooj yim PCB qauv ua tsis raug nqi ntau dua ib qho qeeb. Peb tau pom cov pab pawg engineering tau kub hnyiab los ntawm peb lub voj voog respin vim tias lawv tau kho cov qauv qauv zoo li cov khoom lag luam kev tawm dag zog es tsis yog cov txheej txheem kev siv tau. Ntawm CSNT-EMS hauv Dongguan, peb muab cov qauv tsim nrog 5 txog 15 daim ntau thiab peb -hnub coj lub sijhawm rau cov qauv qhia tshwj xeeb, tab sis tus qauv nrawm tshaj plaws tsis muaj nqi yog tias nws tsis lees paub cov qauv tsim uas tseem ceeb rau koj daim ntawv thov.
Phau ntawv qhia no hais txog dab tsi yuav tsum tau qhia ua ntej kev txiav txim, dab tsi los txheeb xyuas thaum lub sijhawm tshuaj xyuas tus qauv, thiab cov lus nug dab tsi los nug koj tus neeg tsim khoom FPC ua ntej koj cog lus rau kev tsim khoom.
Txhais koj cov qauv tsim kom meej meej
Feem ntau cov qauv kev txiav txim yuam kev yog underspecifying cov yuav tsum tau. Hais tias tsuas yog "peb xav tau tus qauv flex" qhia lub chaw tsim khoom yuav luag tsis muaj dab tsi txog koj qhov kev xav tau tiag tiag. Ib daim qauv ua tiav RFQ yuav tsum suav nrog cov khoom siv substrate (polyimide PI lossis polyester PET), tus naj npawb ntawm cov txheej tooj liab, qhov tsawg kawg ntawm kab dav thiab qhov sib txawv, hom nto tiav, IPC chav kawm yuav tsum tau (feem ntau yog Chav Kawm 2 lossis Chav Kawm 3), thiab seb daim ntawv thov yuav tsum tau static dabtsi yog khoov lossis dynamic flexing hauv kev pabcuam.
Cov khoom specification tseem ceeb nyob rau hauv prototype theem. Yog tias koj npaj yuav siv Panasonic R-F777 hauv kev tsim khoom, qhia nws rau tus qauv. R-F777 muab tev lub zog ntawm 0.525 N ib hli, dhau ntawm IPC/JPCA-6202 Chav Kawm 2 yam tsawg kawg nkaus ntawm 0.49 N ib hli, uas muab cov paj zoo rau cov ntawv thov flex. Siv PI substrate generic rau prototyping thiab tom qab ntawd hloov mus rau R-F777 rau kev tsim khoom tuaj yeem qhia txog qhov sib txawv ntawm kev xyaum zoo, plating adhesion, thiab kev ua haujlwm zoo. Peb tau pom qhov no ua rau kev tsim khoom qeeb thaum tus qauv dhau qhov kev tsim nyog tab sis cov khoom siv tsis tau ua tib yam.
Nkag siab Tus Qauv Lead Sijhawm thiab Cov Nqi
Tus qauv qauv coj lub sij hawm los ntawm Dongguan manufacturers feem ntau khiav tsib mus rau kaum hnub ua hauj lwm rau ob - txheej tsim thiab xya mus rau kaum tsib hnub ua hauj lwm rau ntau - txheej nruj -flex. Kev pabcuam nrawm tuaj yeem txiav cov no los ntawm ib nrab rau qhov ntxiv 30 txog 50 feem pua ntawm cov nqi.
Tus nqi tsav tsheb rau FPC prototypes suav nrog kev teeb tsa engineering (uas kis thoob plaws thawj pawg), cov khoom siv rau cov khoom me me, thiab cov txheej txheem nyuaj. Ib ob - txheej PI flex qauv nrog ENIG tiav feem ntau khiav 150 txog 300 USD rau ib lub rooj tsavxwm nyob ntawm thaj tsam ntawm pawg thawj coj saib thiab cov lus qhia tshwj xeeb. Ntxiv cov lamination ua ntu zus rau nruj -flex thawb tus nqi ntau dua.
Kev siv vaj huam sib luag cuam tshuam rau tus nqi tsim qauv zoo heev. Yog tias koj lub rooj tsav xwm qauv yog 50mm los ntawm 50mm thiab cov chaw tsim khoom tuaj yeem haum 16- rau ntawm lawv cov qauv vaj huam sib luag, koj tus nqi ib thooj yuav qis dua yog tias lawv yuav tsum khiav nws li ib lub vaj huam sib luag. Sib tham txog kev sib tham nrog koj cov chaw tsim khoom ua ntej ua tiav qhov kev tsocai.
Tsim rau Manufacturability Review Ua ntej Tooling
Thov kev tshuaj xyuas DFM los ntawm koj lub chaw tsim khoom ua ntej koj tso koj cov ntaub ntawv rau kev siv. Kev tshuaj xyuas DFM kom zoo feem ntau yuav siv sijhawm ib mus rau ob hnub ua haujlwm thiab npog cov kab thiab qhov chaw kam rau ua rau cov chaw tsim khoom muaj peev xwm ua tau, xyaum qhov loj me thiab ntawm qhov kev txwv tsis pub dhau, flex cheeb tsam geometry thiab khoov lub vojvoog pom zoo, thiab coverlay qhov rais sib dhos nrog cov ntaub qhwv.
30-feeb DFM hu ua ntej tso tawm cov ntaub ntawv tau tiv thaiv respin cycles ntawm txhua tus qauv peb tau khiav hauv ob xyoos dhau los. Cov chaw tsim khoom paub qhov twg lawv cov txheej txheem qhov rais nruj thiab tuaj yeem chij qhov teeb meem ua ntej koj muaj hlau rau ntawm lub rooj tsavxwm.
Piv txwv DFM daim ntawv teev cov khoom rau FPC qauv tshuaj xyuas
Ntsuam xyuas koj tus qauv tsim nyog
Koj daim ntawv pov thawj qauv yuav tsum ua raws li kev tsim nyog tsim nyog hauv cov qauv yog tias tsis nyob hauv cov qauv loj. Yam tsawg kawg nkaus, koj yuav tsum txheeb xyuas qhov ua tau raws li qhov sib txawv ntawm cov gerber specifications siv qhov ntsuas qhov muag, paub meej tias qhov ua tiav qhov zoo thiab cov khoom siv ntawm cov neeg sawv cev, ua tus ntoo khaub lig -section ntawm ib tus qauv txhawm rau txheeb xyuas cov txheej txheem sau npe thiab cov thickness tooj liab, thiab ua qhov ntsuas lub voj voog yog tias lub rooj tsavxwm yuav pom dynamic dabtsi yog khoov hauv kev pabcuam.
Rau Chav Kawm 3 daim ntawv thov, kev sim qauv yuav tsum suav nrog 100 feem pua ntawm kev soj ntsuam pom ntawm txhua cheeb tsam flex ib IPC / JPCA-6202 cov cai, kuj ua piv txwv. Yog tias koj pom qhov tsis xws luag hauv cov qauv, sau lawv nrog cov chaw tsim khoom ua ntej kev tsim khoom tsim nyog.
IPC{0}}TM-650 Method 2.4.9.1 npog dynamic flex testing. Yog tias koj daim ntawv thov xav tau 100,000 flex cycles ntawm ib lub vojvoog khoov tshwj xeeb, khiav qhov kev xeem ntawd ntawm tus qauv thiab sau cov txiaj ntsig. Nrhiav lub neej luv luv ntawm tus qauv yog qhov tsis tshua kim tshaj qhov nrhiav tau tom qab koj tau cog lus rau kev tsim khoom.
Hloov los ntawm Prototype mus rau ntau lawm
Ua ntej koj tso PO ntau lawm, paub meej tias koj lub chaw tsim khoom tau tsim nyog koj cov khoom siv tiag tiag (tseem yog pawg pawg), tau sau cov txheej txheem tsis raug rau koj tus qauv tsim tshwj xeeb, thiab tau txheeb xyuas tias lawv cov kev tshuaj xyuas tuaj rau FCCL thiab coverlay phim cov specifications koj muab.
Cov khoom siv traceability hauv FPC ntau lawm tseem ceeb dua li cov khoom siv PCB nruj vim tias cov khoom siv ntawm PI thiab coverlay muaj ntau pawg ntau dua -rau -batch variation dua FR4. Koj lub chaw tsim khoom yuav tsum muaj peev xwm muab cov ntaub ntawv qhia txog kev taug qab txuas txhua lub vaj huam sib luag rau cov naj npawb tshwj xeeb ntawm FCCL, coverlay, thiab cov tshuaj tiav siv.
Kev tsim tus qauv qauv-rau- tus choj tsim khoom nyob rau pem hauv ntej kawg ntawm qhov kev pab cuam txo lub sij hawm los ntawm kev pom zoo tus qauv mus rau qhov chaw tsim khoom los ntawm qhov nruab nrab ntawm peb lub lis piam hauv peb qhov kev paub.
