Cov Khoom Siv Tshwj Xeeb rau Rigid-Flexible PCBs

Qhia:

Raws li qhov kev thov rau cov ntse, cov khoom siv hluav taws xob compact txuas ntxiv mus, cov tuam txhab tsim kho tshiab txuas ntxiv kom tau raws li cov kev xav tau no. Rigid-flex printed circuit boards (PCBs) tau ua pov thawj tias yog qhov hloov pauv kev ua si, ua kom muaj ntau yam thiab siv tau zoo hauv cov khoom siv hluav taws xob niaj hnub no. Txawm li cas los xij, muaj ib qho kev xav tsis zoo uas kev tsim cov khoom tsis zoo-flex PCBs yuav tsum muaj cov khoom tsim tshwj xeeb. Hauv blog no, peb yuav debunk cov lus dab neeg no thiab sib tham txog vim li cas cov cuab yeej tshwj xeeb no tsis tsim nyog.

1. Nkag siab txog rigid-flex board:

Rigid-flex PCB muab cov txiaj ntsig zoo ntawm lub rooj tsav xwm nruj thiab hloov tau yooj yim kom tsim tau yooj yim, txhim kho kev ntseeg tau thiab txo cov nqi sib dhos. Cov laug cam no muaj kev sib xyaw ua ke ntawm cov tawv tawv thiab hloov tau yooj yim, txuas nrog siv plated los ntawm qhov, cov nplaum nplaum, lossis cov khoom siv tshem tau. Nws cov qauv tshwj xeeb tso cai rau nws khoov, quav lossis twist kom haum rau hauv qhov chaw nruj thiab haum rau cov qauv tsim.

2. Yuav tsum muaj cov khoom tsim tshwj xeeb:

Raws li kev ntseeg nrov, kev nqis peev hauv cov khoom siv tshwj xeeb rigid-flex manufacturing tsis yog ib txwm tsim nyog. Thaum cov boards xav tau kev txiav txim siab ntxiv vim lawv txoj kev tsim kho, ntau cov txheej txheem tsim khoom thiab cov cuab yeej tseem tuaj yeem siv tau. Cov chaw tsim khoom niaj hnub no tau nruab nrog cov tshuab siab heev los tsim cov rigid-flex panels yam tsis tas yuav tsum muaj cov cuab yeej tshwj xeeb.

3. Cov khoom siv tau yooj yim tuav:

Ib qho tseem ceeb ntawm kev tsim khoom nruj-flex PCBs yog kev tuav thiab ua cov ntaub ntawv hloov tau yooj yim. Cov ntaub ntawv no tuaj yeem ua tsis taus thiab yuav tsum tau saib xyuas tshwj xeeb thaum tsim khoom. Txawm li cas los xij, nrog kev cob qhia kom raug thiab cov txheej txheem tsim khoom zoo, cov cuab yeej siv tam sim no tuaj yeem ua cov ntaub ntawv no tau zoo. Kev hloov kho rau clamping mechanisms, kev teeb tsa conveyor thiab cov txheej txheem tuav tuaj yeem ua kom ntseeg tau tias kev tuav tau ntawm cov khoom siv tau yooj yim.

4. Drilling thiab Plating Los Ntawm Qhov:

Rigid-flex boards feem ntau xav tau qhov drilling los ntawm qhov kom sib txuas cov khaubncaws sab nraud povtseg thiab cov khoom. Qee tus yuav ntseeg tias yuav tsum muaj lub tshuab drilling tshwj xeeb vim muaj kev hloov pauv hauv cov khoom siv substrate. Txawm hais tias qee qhov xwm txheej tiag tiag yuav xav tau cov khoom siv dag zog los yog cov spindles siab, cov khoom siv uas twb muaj lawm tuaj yeem ua tau raws li cov kev xav tau no. Ib yam li ntawd, plating los ntawm-qhov nrog cov khoom siv hluav taws xob tuaj yeem ua tiav nrog cov khoom siv txheem thiab cov txheej txheem kev lag luam pov thawj.

5. Copper foil lamination thiab etching:

Copper foil lamination thiab cov txheej txheem etching tom ntej yog cov kauj ruam tseem ceeb hauv kev tsim cov rigid-flex board. Thaum lub sij hawm cov txheej txheem no, txheej ntawm tooj liab yog sib txuas rau lub substrate thiab xaiv tau tshem tawm los tsim cov yam xav tau circuitry. Txawm hais tias cov cuab yeej tshwj xeeb yuav muaj txiaj ntsig zoo rau cov khoom ntim ntau, cov txheej txheem lamination thiab etching tshuab tuaj yeem ua tiav cov txiaj ntsig zoo hauv kev tsim khoom me me.

6. Cov khoom sib dhos thiab vuam:

Kev sib dhos thiab cov txheej txheem soldering kuj tsis tas yuav tsum muaj cov cuab yeej tshwj xeeb rau rigid-flex PCBs. Pov thawj nto mount technology (SMT) thiab cov txheej txheem los ntawm qhov sib dhos tuaj yeem siv rau cov laug cam. Qhov tseem ceeb yog tsim kom tsim nyog rau kev tsim khoom (DFM), kom ntseeg tau tias cov khoom siv tau muab tso rau hauv qhov chaw flex thiab cov ntsiab lus kev ntxhov siab hauv siab.

nyob rau hauv xaus:

Hauv cov ntsiab lus, nws yog ib qho kev xav tsis zoo uas rigid-flex PCBs xav tau cov cuab yeej tsim khoom tshwj xeeb. Los ntawm kev txhim kho cov txheej txheem tsim khoom, ua tib zoo tuav cov ntaub ntawv hloov tau yooj yim, thiab ua raws li cov txheej txheem tsim, cov cuab yeej uas twb muaj lawm tuaj yeem ua tiav cov khoom siv hluav taws xob ntau. Yog li ntawd, cov neeg tsim khoom thiab cov neeg tsim qauv yuav tsum ua haujlwm nrog cov neeg ua haujlwm paub txog kev tsim khoom uas tuaj yeem muab cov kev txawj ntse tsim nyog thiab kev taw qhia thoob plaws hauv cov txheej txheem tsim khoom. Xauv lub peev xwm ntawm nruj-flex PCBs yam tsis muaj lub nra ntawm cov cuab yeej tshwj xeeb muaj kev lag luam muaj peev xwm los txhawb lawv qhov zoo thiab tsim cov khoom siv hluav taws xob tshiab.
