Dab tsi yog hom kev ua tsis tiav ntawm cov rigid-flex boards?

Rigid-flex Circuit Court boards muaj qhov tshwj xeeb tsim zoo, sib txuas cov kev ruaj ntseg ntawm cov laug cam nrog kev hloov pauv ntawm cov khoom siv hluav taws xob.Qhov kev tsim hybrid no ua rau muaj ntau yam khoom siv hluav taws xob thiab ntau yam khoom siv hluav taws xob, ua rau nws zoo tagnrho rau ntau yam kev siv xws li aerospace, khoom siv kho mob thiab khoom siv hluav taws xob.Txawm li cas los xij, zoo ib yam li lwm yam khoom siv hluav taws xob, rigid-flex circuit boards tsis tiv thaiv kev ua tsis tiav.Kev nkag siab txog hom kev ua haujlwm tsis zoo tuaj yeem pab cov engineers tsim kom muaj zog, txhim khu kev qha Circuit Court boards.Nyob rau hauv tsab xov xwm no, peb yuav tshawb txog cov feem ntau tsis ua hauj lwm hom ntawm rigid-flex Circuit Court boards thiab muab kev nkag siab txog yuav ua li cas los tiv thaiv cov tsis ua hauj lwm.

1. Flexible circuit qaug zog:

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm rigid-flex panels yog lawv qhov yooj yim, uas tso cai rau lawv khoov thiab hloov mus rau cov duab nyuaj.Txawm li cas los xij, txuas ntxiv khoov thiab khoov tuaj yeem ua rau flex circuit qaug zog dhau sijhawm.Qhov no tuaj yeem ua rau tawg lossis tawg hauv cov kab tooj liab, uas ua rau qhib circuits lossis kev sib txuas tsis sib xws.Txhawm rau tiv thaiv kev qaug zog ntawm flex Circuit Court, engineers yuav tsum ua tib zoo xav txog qhov khoov vojvoog thiab tus naj npawb ntawm cov voj voog khoov lub rooj tsavxwm yuav tau ntsib thaum lub sijhawm ua haujlwm.Kev txhawb nqa flex circuits nrog cov qauv kev txhawb nqa ntxiv lossis kev siv cov qauv flex dynamic kuj tuaj yeem pab txo qis kev qaug zog.

2. Txheej txheej:

Delamination yog hais txog kev sib cais ntawm cov khaubncaws sab nraud povtseg nyob rau hauv ib tug nruj-flex Circuit Court board.Qhov no tuaj yeem tshwm sim rau ntau yam, suav nrog kev sib txuas tsis zoo ntawm cov khaubncaws sab nraud povtseg, kub caij tsheb kauj vab, lossis kev ntxhov siab txhua yam.Kev delamination tuaj yeem ua rau hluav taws xob luv, qhib, lossis txo qhov kev ntseeg siab ntawm pawg thawj coj saib.Txhawm rau txo qhov kev pheej hmoo ntawm delamination, cov txheej txheem lamination yuav tsum tau ua raws thaum lub sijhawm tsim khoom.Qhov no suav nrog kev siv cov khoom sib txuas zoo, tswj cov txheej txheem lamination, thiab ua kom lub sijhawm kho kom zoo.Tsis tas li ntawd, tsim cov stackups nrog sib npaug tooj liab faib thiab zam kev hloov kub ntau dhau tuaj yeem pab tiv thaiv delamination.

3. Thermomechanical stress:

Rigid-flex boards feem ntau muaj kev nyuaj siab thermomechanical thaum lawv lub neej ua haujlwm.Qhov kev ntxhov siab no tuaj yeem tshwm sim los ntawm kev hloov pauv ntawm qhov kub, av noo, lossis kev poob siab thiab kev co.Thermo-mechanical kev ntxhov siab tuaj yeem ua rau tawg lossis sib koom ua ke tsis ua haujlwm, ua rau muaj teeb meem kev ntseeg tau ntawm hluav taws xob.Txhawm rau txo qhov ua tsis tiav uas cuam tshuam nrog kev ntxhov siab thermomechanical, cov kws ua haujlwm yuav tsum ua tib zoo xaiv thiab tsim nyog cov ntaub ntawv nrog qhov tsim nyog coefficient ntawm thermal expansion (CTE) rau txhua txheej ntawm lub rooj tsavxwm nruj-flex.Tsis tas li ntawd, kev siv cov txheej txheem thermal tswj kom zoo, xws li siv lub dab dej kub lossis thermal vias, tuaj yeem pab tshem tawm cov cua sov thiab txo cov kev ntxhov siab ntawm lub rooj tsavxwm.

4. Kev ua qias tuaj thiab corrosion:

Kev sib kis thiab corrosion yog hom tsis ua haujlwm nyob rau hauv ib qho khoom siv hluav taws xob, thiab cov rigid-flex boards tsis muaj qhov zam.Kev kis kab mob tuaj yeem tshwm sim thaum lub sijhawm tsim khoom lossis vim muaj ib puag ncig xws li av noo lossis raug tshuaj lom neeg.Ntawm qhov tod tes, lub xub ntiag ntawm noo noo los yog corrosive gases feem ntau accelerates corrosion.Ob qho kev kis kab mob thiab kev xeb tuaj yeem ua rau lub rooj tsav xwm hauv Circuit Court kom luv luv lossis ua haujlwm tsis zoo.Txhawm rau tiv thaiv cov kev ua tsis tiav no, kev tswj xyuas nruj yuav tsum tau ua thaum lub sijhawm tsim khoom.Tsis tas li ntawd, conformal coatings los yog encapsulation tuaj yeem muab kev tiv thaiv kev tiv thaiv ib puag ncig.

5. Connector thiab solder joint tsis ua hauj lwm:

Cov khoom sib txuas thiab cov pob qij txha yog qhov tseem ceeb hauv kev sib txuas ntawm cov kab hluav taws xob nruj-flex.Kev ua tsis tiav ntawm cov khoom no tuaj yeem ua rau muaj kev sib txuas tsis sib xws, qhib circuits, lossis txo cov teeb liab kev ncaj ncees.Feem ntau ua rau kev sib txuas thiab kev sib koom ua ke tsis ua haujlwm suav nrog kev ntxhov siab, kev kub ceev, lossis cov txheej txheem soldering tsis raug.Txhawm rau kom ntseeg tau qhov kev ntseeg siab ntawm cov khoom sib txuas thiab cov pob qij txha, cov kws ua haujlwm yuav tsum xaiv cov khoom zoo, xyuas kom zoo thiab haum, thiab ua raws li cov lus qhia zoo xws li qhov kub thiab txias, lub sijhawm, thiab kev siv flux.

Nyob rau hauv cov ntsiab lus, thaum nruj-flex Circuit Court boards muaj ntau yam zoo, lawv muaj kev cuam tshuam rau tej yam tsis ua hauj lwm hom.Kev nkag siab txog cov hom kev ua tsis zoo no yog qhov tseem ceeb rau kev tsim cov kab hluav taws xob ruaj khov thiab muaj zog.Los ntawm kev xav txog tej yam xws li flex Circuit Court qaug zog, delamination, thermomechanical kev nyuaj siab, kev sib kis thiab corrosion, nrog rau cov connector thiab solder sib koom ua hauj lwm tsis ua hauj lwm, engineers muaj peev xwm siv cov kev tiv thaiv tsim nyog thaum lub sij hawm tsim, tsim thiab kev xeem theem.Los ntawm kev ua tib zoo saib xyuas cov kev ua tsis tau zoo no, rigid-flex Circuit Court boards tuaj yeem muab kev ua tau zoo dua thiab ua haujlwm ntev hauv ntau yam kev siv.
