Kev faib tawm ntawm Rigid-Flex PCBs (saib daim duab 1 kom paub meej ntxiv)
Ib lub rooj tsavxwm rigid-flex yog ib lub rooj tsavxwm uas muab kev ruaj khov thiab kev ywj pheej sib xyaw ua ke, ua ob qho tib si kev ruaj khov ntawm lub rooj tsavxwm rigid thiab kev ywj pheej ntawm lub rooj tsavxwm ywj pheej.
Cov khoom siv: TG nruab nrab, TG siab, dielectric tsis tu ncua qis, Df qis FR4, cov khoom siv zaus siab.
Substrate hom: Shengyi, Tenghui, Lianmao, Rogers, Panasonic, DuPont, Taihong.
Qhov chaw tiav: HASL, HASL (Pb Dawb), ENIG, Immersion Tin, Immersion Silver, Gold Plating, OSP, ENIG + OSP, ENEPIG.
Rooj Tswjhwm Rigid-Flex Au/Ni Hom
b Kev plating kub tuaj yeem muab faib ua kub nyias thiab kub tuab raws li qhov tuab. Feem ntau, kub hauv qab 4u”(0.41um) hu ua kub nyias, thaum kub saum 4u” hu ua kub tuab. ENIG tsuas yog ua tau kub nyias, tsis yog kub tuab. Tsuas yog kev plating kub thiaj li ua tau ob qho tib si kub nyias thiab kub tuab. Qhov tuab tshaj plaws ntawm kub tuab ntawm lub rooj tsavxwm ywj pheej tuaj yeem tshaj 40u”. Kub tuab feem ntau yog siv rau hauv cov chaw ua haujlwm nrog kev sib txuas lossis kev tiv thaiv kev hnav.
b Kev plating kub muaj peev xwm muab faib ua kub mos thiab kub tawv raws li hom. Kub mos yog kub ntshiab, thaum kub tawv yog kub uas muaj cobalt. Vim tias cobalt ntxiv rau, qhov nyuaj ntawm txheej kub nce siab tshaj 150HV kom ua tau raws li qhov yuav tsum tau ua kom tsis txhob hnav.
Cov txiaj ntsig ntawm Rigid-Flex Board
Niaj hnub nim no, kev tsim qauv tab tom nrhiav kev ua kom me me, tus nqi qis thiab kev ceev ceev ntawm cov khoom, tshwj xeeb tshaj yog nyob rau hauv kev ua lag luam mobile, uas feem ntau cuam tshuam nrog cov hluav taws xob ceev ceev. Kev siv Rigid-Flex Boards yuav yog qhov kev xaiv zoo heev rau cov khoom siv peripheral txuas nrog IO. Xya qhov zoo tseem ceeb uas coj los ntawm kev tsim qauv xav tau ntawm kev sib koom ua ke cov ntaub ntawv flexible board thiab cov ntaub ntawv rigid board hauv cov txheej txheem tsim khoom, sib txuas 2 cov ntaub ntawv substrate nrog prepreg, thiab tom qab ntawd ua tiav kev sib txuas hluav taws xob interlayer ntawm cov conductors los ntawm qhov lossis qhov muag tsis pom / faus vias yog raws li hauv qab no:
a. 3D sib dhos los txo cov voj voog
b. Kev ntseeg tau zoo dua ntawm kev sib txuas
c. Txo cov naj npawb ntawm cov khoom thiab cov khoom seem
d. Kev sib xws zoo dua ntawm impedance
e. Tsim tau cov qauv stacking nyuaj heev
f. Tsim kom muaj tus qauv zoo nkauj dua
g. Txo qhov loj me

Daim Ntawv Thov Rigid-Flex Board (saib daim duab 3-1 kom paub meej ntxiv)
Rigid-flex PCB yog ib lub rooj tsavxwm sib xyaw nrog cov yam ntxwv ntawm ob qho tib si flexible circuit board thiab rigid circuit board, uas yog siv dav hauv cov teb raws li hauv qab no:
1. Kev lag luam hluav taws xob: Cov PCBs Rigid-flex siv dav hauv cov khoom siv hluav taws xob xws li xov tooj ntawm tes, ntsiav tshuaj, cov khoom siv ntse hnav tau, lub koob yees duab, cov tshuab kaw video, lub tshuab xam zauv, drones thiab cov saib xyuas kev noj qab haus huv. Hais txog kev ua tau zoo, nws cov laug cam rigid thiab flexible tuaj yeem txuas cov PCBs thiab cov khoom sib txawv hauv txoj kev peb-seem. Ntawm tib lub voj voog ceev, nws tuaj yeem ua rau thaj chaw siv tag nrho ntawm PCB, txhim kho nws lub peev xwm nqa lub voj voog, thiab txo qhov txwv kev xa xov thiab qhov yuam kev sib dhos ntawm cov neeg sib cuag. Hais txog kev tsim kho, cov PCBs rigid-flex yog lub teeb yuag thiab nyias, tso cai rau kev xaim hluav taws xob, uas yog qhov pab tau zoo hauv kev txo qhov ntim thiab qhov hnyav.
2. Kev lag luam tsheb: Cov PCBs rigid-flex feem ntau siv rau hauv cov tshuab hluav taws xob hauv tsheb, suav nrog cov nyees khawm rau kev txuas lub motherboard rau lub kauj tsheb, kev sib txuas ntawm lub vijtsam video system ntawm lub tsheb thiab lub vaj huam sib luag tswj, kev sib txuas ua haujlwm ntawm cov nyees khawm suab lossis cov nyees khawm ua haujlwm ntawm lub qhov rooj sab, lub kaw lus radar rov qab, cov sensors, lub kaw lus sib txuas lus hauv tsheb, kev taw qhia satellite, lub rooj tsavxwm rau kev txuas lub vaj huam sib luag tswj lub rooj zaum tom qab thiab lub maub los pem hauv ntej, thiab lub kaw lus ntes sab nraud.
3. Cov khoom siv kho mob: Kev siv cov PCBs rigid-flex hauv cov khoom siv kho mob tau dhau los ua qhov dav dua, xws li cov khoom siv saib xyuas cov cim, cov cuab yeej kho mob, cov khoom siv thaij duab, cov khoom siv kho lub cev, cov tshuab pacemakers plawv, endoscopes, cov khoom siv tswj ultrasound, thiab lwm yam. Cov khoom lag luam hauv cov teb no xav tau kev ntseeg siab siab, kev raug siab, kev poob qis impedance, kev xa cov teeb liab tiav, kev ruaj khov, thiab lwm yam. Vim yog qhov nyuaj ntawm cov txheej txheem tsim khoom thiab cov zis tsawg, tus nqi tsim khoom siab.
4. Kev tswj hwm kev lag luam: Cov PCBs rigid-flex siv rau ntau yam kev siv hauv kev lag luam suav nrog cov satellites cuav, radar systems, kev sib txuas lus wireless, laser ntsuas thiab tswj cov cuab yeej, sensors, nuclear magnetic analyzers, X-ray devices, infrared analyzers, thiab lwm yam.
