Rigid Flex luam tawm Circuit Boardyog ntau- txheej txheej luam tawm Circuit Board uas sib txuas ua ke nruj thiab hloov tau yooj yim Circuit Court boards los ntawm txheej txheem lamination. Nws sib txuas cov kev txhawb nqa ntawm cov cheeb tsam nruj nrog kev hloov pauv ntawm thaj chaw hloov tau yooj yim thiab tau siv dav hauv cov teb siab -kawg xws li cov xov tooj foldable thiab cov khoom siv kho mob. cov
Cov txiaj ntsig tseem ceeb thiab cov yam ntxwv thev naus laus zis
Lub rigid saj zawg zog ua ke board daws cov kev txwv ntawm ib txwm circuits los ntawm kev tsim tshiab:
Qhov chaw thiab qhov hnyav ua kom zoo: Qhov hloov pauv tau tuaj yeem khoov thiab quav, txo cov khoom sib txuas thiab cov cables, txo cov khoom ntim los ntawm 40% thiab qhov hnyav los ntawm 30%, haum rau cov xwm txheej compact xws li cov khoom siv hnav lossis drones. cov
Kev txhim kho kev ntseeg tau: Kev tsim qauv sib xyaw kom txo tau 60% ntawm cov ntsiab lus txuas tsis ua haujlwm, dhau 100000 dynamic dabtsi yog khoov kuaj (xws li folding xov tooj hinges), thiab muaj qhov kub tsis kam ntawm -55℃txog 125 degree.
Kev ruaj ntseg teeb pom kev zoo: nti kev teeb tsa hauv thaj chaw nruj, xaim hauv thaj chaw hloov tau yooj yim, impedance tswj qhov tseeb ntawm ± 5 Ω, txo cov electromagnetic cuam tshuam, haum rau 5G kev sib txuas lus lossis tsheb radar. cov
Cov chaw siv tseem ceeb
Cov khoom siv hluav taws xob siv hluav taws xob: cov xov tooj uas siv tau (xws li 200+ cov kab sib xyaw ua ke hauv thaj tsam 3cm hloov tau ntawm lub pob khawm), smartwatches, ua tiav lub neej folding ntawm 100000 zaug. cov
Cov cuab yeej kho mob: Endoscope (50cm ntev khoov 90℃rau hauv tib neeg lub cev), cochlear implant, biocompatible khoom raws li kev cog qoob loo. cov
Automotive electronics: Lub hauv paus tswj qhov system txo cov connectors los ntawm 80%, thiab lub onboard radar ua raws li qhov nkhaus ntawm lub bumper, txhim kho kev tshawb pom qhov tseeb. cov
Cov txheej txheem tsim khoom thiab cov thev naus laus zis tseem ceeb
Khoom siv sib xyaw:
Rigid txheej: FR-4 epoxy resin (thickness 0.2-1.6mm), muab txhua yam kev txhawb nqa.
Flexible txheej: polyimide zaj duab xis (0.025-0.1mm), tiv taus kub ntawm 260 degree,
Cov txheej txheem tseem ceeb:
Txheej: 5-7 compressions los tswj CTE qhov sib txawv (rigid 18ppm /℃C vs saj zawg zog 30ppm /℃C). cov
Drilling: UV laser ua ntawm 50 μ m micropores, mem tes electroplating nrog tooj liab filling thickness rau txoj kab uas hla ntawm 1.0. cov
Cov qauv xeem: IPC-ET-652 kev ntsuas hluav taws xob, nrog kev hloov pauv tsis zoo ntawm 20% tom qab 150000 bending cycles. cov
Cov txheej txheem tsim khoom ntawm lub rooj tsav xwm nruj flex Circuit board (rfpcb) yog qhov tseeb, tab sis cov tub ntxhais nyob rau hauv kev sib xyaw ua ke ntawm cov khoom nruj thiab hloov tau yooj yim, uas yuav tsum muaj ob qho tib si lub zog thiab hloov tau yooj yim. Cov hauv qab no yog cov txheej txheem tseem ceeb ntws:
1, Core txheej txheem ntws
Kev npaj khoom siv
FR-4 substrate yog siv rau cov laug cam, PI zaj duab xis yog siv rau cov boards hloov tau yooj yim, thiab yuav tsum tau tswj qhov loj me.
Plasma tu txhim kho qhov roughness thiab txhim kho adhesion.
Sab hauv txheej graphic processing
Cov qauv kab yog tsim los ntawm cov zaj duab xis qhuav lamination, laser direct imaging (LDI), los yog ib txwm ua yeeb yaj kiab raug.
Laser lub hom phiaj qhov chaw ua kom ntseeg tau qhov sib txawv ntawm qhov sib txawv (tsawg dua lossis sib npaug li 50 μ m).
Txheej thiab Drilling
Kev kub siab thiab kev kub siab compression ntawm cov khaubncaws sab nraud povtseg nruj, cov khaubncaws sab nraud povtseg, thiab cov ntaub nplaum nplaum, tswj qhov kub thiab txias, siab, thiab lub sijhawm.
Mechanical Drilling nyob rau hauv lub rigid board cheeb tsam, CO ₂ los yog UV laser drilling nyob rau hauv lub nruj flex cheeb tsam (aperture yuav me me li 0.1 hli).
Qhov metallization thiab txheej txheej txheej duab
Tshuaj tooj liab deposition (PTH) thiab electroplated tooj liab filling ntawm pore phab ntsa.
Cov txheej txheej sab nraud ntawm lub voj voog yog ua tiav los ntawm kev raug thiab etching, thiab kev saib xyuas yuav tsum tau them rau kev tiv thaiv ntawm cov zaj duab xis npog nyob rau hauv lub nruj flex cheeb tsam.
Qhov tshwm sim ua thiab kuaj
Kev sib txuas ntawm laser txiav nrog cov tshuab milling kom tsis txhob ua rau thaj tsam nruj flex.
Flying needle test los yog tshwj xeeb fixture test rau hluav taws xob kev ua tau zoo.
