Cov ntsiab lus hauv qab no yuav tsum tau txiav txim siab hauv FPC pwm tsim:
① Xaiv cov pwm hlau
② Pwm tsim cov txheej txheem tsim khoom
③ Pwm qauv tsim
④ Tus naj npawb ntawm pwm kab noj hniav
⑤ Layout ntawm pwm positioning pins
⑥ Pwm ua ntej- nthuav dav thiab ua ntej- shrinkage
1. Kev xaiv cov pwm hlau
Muaj ntau hom hlau muaj nyob rau hauv kev ua lag luam, ob qho tib si hauv tsev thiab txawv teb chaws. Txawm li cas los xij, feem ntau cov tuam ntxhab siv cov hlau tuaj txawv teb chaws, xws li Nyiv (HITACHI), Sweden (ASSAB), Lub Tebchaws Yelemees (SSE), thiab Austria (BOHLER), uas feem ntau ua tau zoo. Rau FPC pwm, siab- pwm hlau zoo yog qhov tseem ceeb, yuav tsum tau muaj zog hardness, zoo hardenability, thiab tsis tshua muaj hlau EDM kev nyuaj siab, xws li Japanese SKD61 thiab SKD11.
2. Pwm tsim cov txheej txheem tsim khoom
Vim tias FPC xav tau cov duab siab thiab qhov tseeb qhov tseeb, kev ua haujlwm ntawm cov pwm nws tus kheej yog qhov xav tau heev. Feem ntau, qeeb -ceev xaim EDM yuav tsum tau ua. Qhov zoo ntawm cov hlau EDM yog ib qho tseem ceeb cuam tshuam rau pwm kev ua tau zoo, uas yog ze rau lub tshuab qib thiab cov neeg ua haujlwm cov kev txawj ntse. Cov txheej txheem pwm sib dhos yog ib feem tseem ceeb ntawm cov txheej txheem tom qab ntawm cov txheej txheem thiab tseem ceeb heev. Nws tseem yuav tsum tau txiav txim siab tias thaum kho cua sov, cov txiv neej thiab poj niam pwm yuav tsum muaj qhov sib txawv ntawm qhov kub ntawm 8-10 degrees los pab kho pwm.
3. Pwm qauv tsim
Pwm qauv tsim yog yooj yim heev nyob rau hauv hlau stamping tuag, muab faib ua blanking hom thiab nto -forming hom. Rau stamping cover films, thermosetting nplaum zaj duab xis, plating kab, PI thiab FR4 reinforcing nplooj ntawv, blanking hom yog siv vim cov ntaub ntawv no tsis yooj yim deformed thiab efficiency siab dua; rau cov duab sab nraud, kom tsis txhob muaj qhov deformation, thiab vim tias feem ntau muaj cov txheej txheem qhov, qhov saum npoo - hom kev sib sau yog siv; Tsis tas li ntawd, stainless hlau reinforcing sheets siv cov nto- hom vim blanking yuav ua rau deformation.
4. Tus naj npawb ntawm cov kab noj hniav hauv pwm
Txhawm rau ua kom muaj peev xwm ntau lawm thiab ua haujlwm tau zoo, cov kab noj hniav ntau dua feem ntau zoo dua. Txawm li cas los xij, qhov no yog txwv los ntawm qhov loj ntawm cov xovxwm platform, pwm stability, thiab kev ruaj ntseg ntawm FPC substrate nws tus kheej, nrog rau cov naj npawb ntawm cov khoom uas tuaj yeem npaj raws li cov khoom zoo. Pwm nqi thiab kev tsim qauv tsim nyog yuav tsum tau txiav txim siab. Rau cov khoom uas yuav tsum tau ua siab ntev, FPC pwm feem ntau muaj ib los yog ob kab noj hniav.
5. Layout ntawm Pwm Positioning Pins
Positioning pins yog siv los nrhiav cov khoom kom raug stamped. Stamping pwm yuav tsum muaj kev sib npaug sib npaug, thiab FPC pwm tsis muaj qhov tshwj xeeb. Cov pwm pwm yuav tsum nyob nruab nrab kom ntau li ntau tau, yog li cov pins muab tso rau hauv ib ncig ntawm cov khoom. Txawm li cas los xij, cov kev cai tshwj xeeb ntawm cov khoom nws tus kheej kuj yuav tsum tau txiav txim siab. Piv txwv li, nyob rau hauv cov cheeb tsam uas muaj kev zam tshwj xeeb rau cov ntiv tes thiab qhov chaw nyob deb, cov pins yuav tsum muab tso rau ze li sai tau.
6. Pwm Pre-expansion thiab Pre-shrinkage
Rau cov cheeb tsam uas yuav tsum tau ua siab ntev rau cov khoom, tshwj xeeb tshaj yog cov ntiv tes kub, yog tias qhov yuav tsum tau yog +/-0.05MM, thiab cov pwm tsis tuaj yeem ua tiav qhov kev ua siab ntev, kev kho pwm yog tsim nyog. Kev txiav txim siab tias cov pwm yuav hnav tom qab siv qee lub sijhawm, unilateral pre-shrinkage ntawm 0.02 yog siv rau qhov ntiv tes ntawm cov pwm. Cov chaw tsim khoom pwm yuav tsum tau ua ntej-shrink ob kab thaum ua. Tom qab qhov kev kho mob no, qhov tsis xws luag, tshwj xeeb tshaj yog rau cov ntiv tes, tsuas yog kwv yees li 1%. Yog tsis muaj qhov kev kho mob no, qhov tsis xws luag yuav ntau dua 10%.
