Hauv cov khoom siv sib txuas lus 5G yav tom ntej, daim ntawv thov ntawm cov ntawv ci tooj liab yuav nthuav dav ntxiv, feem ntau yog nyob rau hauv cov chaw hauv qab no:
1. Cov PCBs Zaus Siab (Cov Rooj Tswjhwm Luam Tawm)
- Cov Ntawv Nyiaj Tooj Liab Uas Tsis Tshua Muaj Peev Xwm Poob: Kev sib txuas lus 5G qhov ceev ceev thiab qis latency xav tau cov txheej txheem xa cov teeb liab zaus siab hauv kev tsim lub rooj tsavxwm circuit, ua rau muaj kev xav tau ntau dua rau cov khoom siv conductivity thiab kev ruaj khov. Cov ntawv ci tooj liab qis poob, nrog nws qhov chaw du, txo qhov kev poob ntawm kev tiv thaiv vim yog "cov nyhuv ntawm daim tawv nqaij" thaum lub sijhawm xa cov teeb liab, tswj kev ncaj ncees ntawm cov teeb liab. Cov ntawv ci tooj liab no yuav siv dav hauv cov PCBs zaus siab rau 5G chaw nres tsheb hauv paus thiab antennas, tshwj xeeb tshaj yog cov uas ua haujlwm hauv millimeter-wave frequencies (saum toj no 30GHz).
- Cov Ntawv Nyiaj Tooj Liab Siab PrecisionCov antennas thiab RF modules hauv 5G li xav tau cov khoom siv high-precision los ua kom zoo dua qhov kev xa tawm thiab kev txais tos. Qhov kev coj ua siab thiab kev siv tshuab ntawmntawv ci tooj liabua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov antennas me me, siab zaus. Hauv 5G millimeter-wave technology, qhov twg antennas me dua thiab xav tau kev xa xov tooj cua zoo dua, ultra-thin, high-precision tooj liab ntawv ci tuaj yeem txo qhov teeb liab attenuation thiab txhim kho kev ua haujlwm ntawm antenna.
- Cov Khoom Siv Conductor rau Cov Voj Voog Yooj YimNyob rau hauv lub caij nyoog 5G, cov khoom siv sib txuas lus sib txawv ntawm qhov sib dua, nyias dua, thiab yoog tau ntau dua, ua rau muaj kev siv dav dav ntawm FPCs hauv cov xov tooj ntse, cov khoom siv hnav tau, thiab cov davhlau ya nyob twg hauv tsev ntse. Cov ntawv ci tooj liab, nrog nws qhov kev ywj pheej zoo heev, kev coj hluav taws xob, thiab kev tiv thaiv kev qaug zog, yog cov khoom siv hluav taws xob tseem ceeb hauv kev tsim khoom FPC, pab cov circuits ua tiav kev sib txuas zoo thiab kev xa cov teeb liab thaum ua tau raws li cov kev xav tau ntawm 3D wiring.
- Cov Ntawv Nyiaj Tooj Liab Ultra-Thin rau Multi-Layer HDI PCBs: HDI thev naus laus zis yog qhov tseem ceeb rau kev ua kom me me thiab kev ua haujlwm siab ntawm 5G cov khoom siv. HDI PCBs ua tiav qhov ceev ntawm lub voj voog thiab cov nqi xa teeb liab ntau dua los ntawm cov xov hlau me me thiab cov qhov me me. Cov qauv ntawm cov ntawv ci tooj liab ultra-thin (xws li 9μm lossis nyias dua) pab txo cov tuab ntawm lub rooj tsavxwm, ua kom cov teeb liab xa ceev thiab kev ntseeg siab, thiab txo qhov kev pheej hmoo ntawm kev sib txuas lus teeb liab. Cov ntawv ci tooj liab ultra-thin no yuav siv dav hauv 5G smartphones, chaw nres tsheb hauv paus, thiab routers.
- Cov Ntawv Nyiaj Tooj Liab Uas Muaj Kev Ua Haujlwm Zoo Tshaj Plaws: Cov khoom siv 5G tsim cov cua sov loj thaum lub sijhawm ua haujlwm, tshwj xeeb tshaj yog thaum tuav cov teeb liab siab thiab cov ntaub ntawv loj, uas ua rau muaj kev xav tau ntau dua rau kev tswj hwm thermal. Cov ntawv ci tooj liab, nrog nws cov thermal conductivity zoo heev, tuaj yeem siv rau hauv cov qauv thermal ntawm 5G cov khoom siv, xws li cov ntawv thermal conductive, cov yeeb yaj kiab dissipation, lossis cov txheej thermal adhesive, pab kom sai sai hloov cua sov los ntawm qhov chaw cua sov mus rau cov dab dej cua sov lossis lwm yam khoom, txhim kho kev ruaj khov thiab lub neej ntev ntawm cov khoom siv.
- Daim ntawv thov hauv LTCC ModulesHauv cov khoom siv sib txuas lus 5G, LTCC thev naus laus zis siv dav hauv RF pem hauv ntej modules, lim dej, thiab antenna arrays.Cov ntawv ci tooj liab, nrog nws cov conductivity zoo heev, tsis tshua muaj resistivity, thiab yooj yim ntawm kev ua tiav, feem ntau yog siv ua cov khoom siv txheej conductive hauv LTCC modules, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej xa xov ceev ceev. Tsis tas li ntawd, cov ntawv ci tooj liab tuaj yeem coated nrog cov khoom siv tiv thaiv oxidation los txhim kho nws qhov ruaj khov thiab kev ntseeg siab thaum lub sijhawm LTCC sintering.
- Cov Ntawv Nyiaj Tooj Liab rau Millimeter-Wave Radar Circuits: Cov radar millimeter-wave muaj ntau daim ntawv thov hauv lub caij 5G, suav nrog kev tsav tsheb tsis muaj neeg tsav thiab kev ruaj ntseg ntse. Cov radar no yuav tsum ua haujlwm ntawm cov zaus siab heev (feem ntau ntawm 24GHz thiab 77GHz).Cov ntawv ci tooj liabsiv tau los tsim cov RF circuit boards thiab antenna modules hauv radar systems, muab kev ncaj ncees ntawm lub teeb liab thiab kev ua haujlwm kis tau zoo heev.
2. Cov Antennas Me Me thiab Cov Modules RF
3. Cov Rooj Tswjhwm Luam Tawm Yooj Yim (FPCs)
