Polyphenylene sulfide (PPS)Yog ib hom ntawm thermoplastic tshwj xeeb engineering yas nrog cov khoom siv zoo. Nws cov yam ntxwv zoo yog muaj kub siab kuj, corrosion tsis kam thiab siab dua cov khoom siv zoo dua.
PPS yog dav siv nyob rau hauv tsheb, hluav taws xob thiab kev lag luam hluav taws xob, kev sib txuas lus kev ua tub rog, yog ib qho ntawm feem ntau siv cov kev lag luam uas muaj kev tsim kho tshiab.
Nrog kev tawm tsam ntawm 5G era, PPS kuj tau nthuav mus rau hauv cov teb no.
5G yog lub thib tsib tiam ntawm kev sib txuas lus kev sib txuas lus, kev kis tau 100 zaug ntawm 4G, yog li 5G cov ntaub ntawv muaj cov high ua rau dielectric tas li.Feem ntau, qhov tso cai ntawm cov khoom cob cov khoom cob tau tsuas yog yuav tsum tau nyob hauv qab 3.7 rau 4G cov khoom lag luam, thaum lub sij hawm permittivity ntawm cov khoom siv cob tau yog feem ntau yuav tsum tau nyob nruab nrab ntawm 2.8 thiab 3.2 rau 5G cov khoom.

Cov yam ntxwv ntawm PPS
1. Thermal Khoom
PPS muaj cov kub kub ua tau, tshwj xeeb tshaj yog nyob rau hauv cov av siab siab thiab kev ntxhov siab siab. PPS hluav taws xob rwb thaiv tsev Thaum Tshav Kub Kub Kub Kub Ua Ntej Qib Rau F (Yaebfh Qib, Qib Kub Ua Ntej Qib Ntxiv Nyob Hauv Tig). Cov yeeb yaj kiab Pps muaj cov nplaim hluav taws xob siab dua (tus kheej-extinguishing) thaum tsis muaj kev sib ntxiv hlo li. Pps Zaj Duab Xis Dua 25mm yog pom tias UL94 V0 cov khoom siv.
2. Neeg yam ntxwv kho tshuab
Cov khoom siv tensile thiab ua cov yeeb yaj kiab ntawm cov yeeb yaj kiab Pps zoo ib yam li cov tsiaj, thiab cov yeeb yaj kiab muaj zog tseem siv tau los ua cov ntaub ntawv rwb thaiv tsev cuam tshuam nrog superconductivity.
Ntxiv mus, lub sij hawm ntev creep thiab noo noo kev ua yeeb yaj kiab yog qhov muaj zog me me, yog li qhov muaj peev xwm hloov tau tus tsiaj ua cov sib nqus me me hauv nruab nrab, Kev thaij duab thiab lwm yam duab ntsig txog cov ntaub ntawv zaj duab xis zaj duab xis.
3. Tshuaj lom neeg
PPS resistant rau feem ntau cov kuab tshuaj muaj kuab, tsuas yog nyob rau hauv lub acid acid, tsuas yog nyob rau hauv 2-chlornaphthalene, Diphenyl ether saum 200 ℃ tsuas yog pib yaj,Nws txoj kev tawm tsam yog ob tsuas yog rau yas tus txiv neej PTFE.
4. Hluav Taws Xob
PPS muaj cov yam ntxwv loj zaus hluav taws xob, nws dielectric tas li yog tsis tshua muaj neeg kub thiab zaus, thiab nws cov dielectric tsis muaj zog yog me me txaus rau cov polypropylene. Raws li capacitor dielectric, nws muaj peev xwm muaj peev xwm tsawg ntawm qhov kub thiab zaus, yog li cov tsis muaj peev xwm capacitor tuaj yeem tau txais.

5. Lwm qhov ua tau zoo
Lub nras muaj kev ntxhov siab ntawm PPS Zaj Duab Xis yog qis dua li cov tsiaj zaj duab xis, tab sis nws kuj yog qhov tsim nyog rau txheej. Nyob rau hauv cov ntaub ntawv nyob qhov twg nplaum tau siv nrog lwm zaj duab xis Laminates, lub nplaim yuav tsum yog kho Corona kho kom nce npoo av kom muaj 58d / cm.
Qhov saum npoo roughness thiab kev sib txhuam coefficient ntawm PPS zaj duab xis tuaj yeem hloov kho raws li lub hom phiaj zoo li tus tsiaj ib yam li tsiaj. PPS membrane yog ib qho ntawm ob peb cov organic weepbranes uas tuaj yeem siv rau hauv lub periphery ntawm rauveactor thiab fusion rauv vim ntawm nws siab ntev tawm tsam r duab ci thiab neutrron tshav.

Daim ntawv thov ntawm PPS hauv 5G teb
1. FPC (SLELEATION Circuit Coffuit Board) yog qhov yuav tsum muaj nyob hauv 5g kev lag luam mus ib txhis.
Saj zawg zog Circuit Court (FPC) yog Tebchaws Asmeskas nyob rau xyoo 1970 rau kev txhim kho cov yas yas hluav taws xob, yog li tias muaj qhov chaw nqaim thiab txwv chaw, yog li ntawd los ua circuit siv tau yooj yim.
Ua kua Crystal polymer (LCP) zaj duab xis tau siv dav hauv kev ua lag luam. Txawm li cas los xij, tus nqi siab thiab ua tus yam ntxwv ntawm LCP tseem yog teeb meem, yog li rov tshwm sim ntawm cov khoom tshiab yog qhov ceev tau ntawm kev ua lag luam.
Toray tau ua tau zoo rau kev ua lag luam thiab thov nrog nws cov tshuab thev naus laus zis los tsim kho kom muaj ncab polyphenylene sulfide (pps) zaj duab xis Torelina®. Nws muaj tib yam lossis txawm tias cov khoom pov thawj dielectric zoo dua li LCP zaj duab xis.
Torelina ® Daim Ntawv Thov
Hluav Taws Xob Rwb Thaiv Tsev Khoom Siv (Tsav / Transformer / Hlau)
Cheebtsam hluav taws xob (lithium roj teeb / Capacies)
Engineering Nyias Zaj Duab Xis (Khoom Siv Hluav Taws Xob)
Qhov zoo hauv FPC
Cov ntaub ntawv nrog cov khoom noj qis qis hauv cov zog ntau.
Ruaj khov kho tsis tau raws li qhov kub thiab vaum huab cua.
Nyob rau hauv lub tsheb, kev lag luam hluav taws xob tau muaj pawg ntau lawm.
Cov dej nqus dej qis & Hydrolysis tsis kam.
Nws yog qhov kev xaiv zoo tshaj plaws rau lcp & mpi (hloov polyimide).
2. Yas kav hlau txais xov oscillator
Qhov npe hu ua Antenna oscillator tsuas yog ib qho ntawm cov hlau tus neeg coj ua thiab tau txais cov phiajcim zoo tshaj oscillating teeb liab. Nov yog 4G kav hlau txais xov, thiab 5g kav hlau txais xov yuav yog me dua.
Antenna Vibrator siv cov khoom siv yog hlau lossis siv cov khoom siv hlau, tuaj yeem cia cov kav hlau ntseej, tuaj yeem ua rau kav hlau txais xov, tuaj yeem kim heev, Yog li nyob rau hauv 5 g kavenna oscillator tsim yog qhov tseem ceeb tshaj plaws kev xaiv ntawm qhov kub ua kom sov txhim kho kev plastics.
Yas Antenna Oscillator
Tus kav hlau txais xov osCillator tuaj yeem hloov kho nrog 40% iav fiber cuam txhawb nqa PPS, uas muaj qhov hnyav dua, txo qis dua LCP thiab PCB oscillator, thiab pcb oscillator, thiab cov pcb oscillator, thiab cov lej pcb zoo dua. Nws yuav tsum dhau los ua cov khoom siv.
