Cov txheej txheem tswj kev nthuav dav thiab kev cog lus ntawm FPC cov ntaub ntawv

Qhia

Flexible printed circuit (FPC) cov ntaub ntawv tau siv dav hauv kev tsim khoom siv hluav taws xob vim lawv qhov yooj yim thiab muaj peev xwm ua kom haum rau hauv qhov chaw compact. Txawm li cas los xij, ib qho kev sib tw los ntawm FPC cov ntaub ntawv yog kev nthuav dav thiab kev cog lus uas tshwm sim vim qhov kub thiab txias hloov pauv. Yog tias tsis tswj tau zoo, qhov kev nthuav dav thiab kev cog lus no tuaj yeem ua rau cov khoom deformation thiab tsis ua haujlwm.Hauv qhov blog no, peb yuav tham txog ntau txoj hauv kev los tswj kev nthuav dav thiab kev cog lus ntawm FPC cov ntaub ntawv, suav nrog cov qauv tsim, xaiv cov khoom siv, txheej txheem tsim, khaws cov khoom, thiab cov txheej txheem tsim khoom. Los ntawm kev siv cov txheej txheem no, cov tuam txhab lag luam tuaj yeem ua kom ntseeg tau thiab ua haujlwm ntawm lawv cov khoom FPC.

Tsim nam

Thaum tsim FPC circuits, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov nthuav dav ntawm cov ntiv tes crimping thaum crimping ACF (Anisotropic Conductive Film). Precompensation yuav tsum tau ua los tiv thaiv kev nthuav dav thiab tswj qhov ntev uas xav tau. Tsis tas li ntawd, cov txheej txheem ntawm cov khoom tsim yuav tsum sib npaug thiab sib npaug sib npaug thoob plaws qhov kev teeb tsa. Qhov tsawg kawg nkaus nyob deb ntawm txhua ob PCS (Printed Circuit System) cov khoom yuav tsum khaws cia siab tshaj 2MM. Tsis tas li ntawd, cov khoom tsis muaj tooj liab thiab cov khoom ntawm qhov ntom ntom yuav tsum tau staggered kom txo qhov cuam tshuam ntawm cov khoom nthuav dav thiab kev cog lus thaum lub sij hawm tsim cov txheej txheem tom ntej.

Kev xaiv khoom

Kev xaiv cov ntaub ntawv ua lub luag haujlwm tseem ceeb hauv kev tswj kev nthuav dav thiab kev cog lus ntawm FPC cov ntaub ntawv. Cov kua nplaum siv rau txheej yuav tsum tsis txhob thinner tshaj qhov tuab ntawm cov ntawv ci tooj liab kom tsis txhob muaj cov kua nplaum tsis txaus thaum lub sij hawm lamination, ua rau cov khoom deformation. Lub thickness thiab txawm faib cov kua nplaum yog qhov tseem ceeb hauv kev nthuav dav thiab kev cog lus ntawm FPC cov ntaub ntawv.

Txheej Txheem Tsim

Kev tsim cov txheej txheem tsim nyog yog qhov tseem ceeb rau kev tswj cov kev nthuav dav thiab kev cog lus ntawm FPC cov ntaub ntawv. Cov zaj duab xis npog yuav tsum npog tag nrho cov ntawv ci tooj liab kom ntau li ntau tau. Nws tsis pom zoo kom siv cov yeeb yaj kiab hauv cov strips kom tsis txhob muaj kev ntxhov siab tsis sib xws thaum lamination. Tsis tas li ntawd, qhov loj ntawm PI (polyimide) reinforced daim kab xev yuav tsum tsis pub tshaj 5MIL. Yog tias nws tsis tuaj yeem zam tau, nws raug nquahu kom ua PI txhim kho lamination tom qab npog zaj duab xis nias thiab ci.

Cov ntaub ntawv khaws cia

Kev ua raws li cov ntaub ntawv khaws cia yog qhov tseem ceeb rau kev tswj xyuas qhov zoo thiab ruaj khov ntawm cov ntaub ntawv FPC. Nws yog ib qho tseem ceeb kom khaws cov ntaub ntawv raws li cov lus qhia los ntawm tus neeg muag khoom. Lub tub yees yuav tsum tau nyob rau qee kis thiab cov tuam txhab tsim khoom yuav tsum xyuas kom meej tias cov ntaub ntawv khaws cia raws li kev pom zoo los tiv thaiv kev nthuav dav thiab kev cog lus tsis tsim nyog.

Kev Siv Tshuab

Ntau hom kev tsim khoom siv tau los tswj kev nthuav dav thiab kev cog lus ntawm FPC cov ntaub ntawv. Nws raug nquahu kom ci cov khoom ua ntej drilling kom txo qis kev nthuav dav thiab kev cog lus ntawm cov substrate los ntawm cov dej noo siab. Kev siv plywood nrog luv luv tuaj yeem pab txo qis kev cuam tshuam los ntawm kev ntxhov siab dej thaum lub sij hawm plating. Lub viav vias thaum plating tuaj yeem raug txo kom tsawg, thaum kawg tswj kev nthuav dav thiab kev cog lus. Tus nqi ntawm cov plywood siv yuav tsum tau ua kom zoo kom ua tiav qhov sib npaug ntawm kev tsim khoom zoo thiab cov khoom siv me me deformation.

Hauv kev xaus

Tswj kev nthuav dav thiab kev cog lus ntawm FPC cov ntaub ntawv yog qhov tseem ceeb los xyuas kom meej qhov kev ntseeg tau thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob. Los ntawm kev txiav txim siab tsim qauv, xaiv cov khoom siv, txheej txheem tsim, khaws cov khoom siv thiab kev tsim khoom siv tshuab, cov tuam txhab tuaj yeem tswj xyuas qhov nthuav dav thiab cog lus ntawm FPC cov ntaub ntawv. Cov lus qhia dav dav no muab kev nkag siab zoo rau ntau txoj hauv kev thiab cov kev xav xav tau rau kev tsim FPC ua tiav. Kev ua raws li cov txheej txheem no yuav txhim kho cov khoom zoo, txo qhov ua tsis tiav, thiab ua kom cov neeg siv khoom txaus siab.
