PTFE thiab hydrocarbon resin tsis yog hloov pauv rau kev ua haujlwm siab lossis qis hauv high-frequency board customization, tab sis qhov kev xaiv sib txawv ntawm cov xwm txheej sib txawv: lub qub yog "kev ua haujlwm qab nthab" tsim los rau qhov kawg ntawm RF kev ua tau zoo, thaum lub tom kawg yog "engineering pom kev daws teeb meem" uas yuav siv rau hauv cov khoom lag luam zoo. Cov ntsiab lus xaiv cov ntsiab lus hloov pauv nyob ib puag ncig peb qhov ntev: qhov pib zaus, cov txheej txheem nyuaj, thiab cov nplai ntau lawm, tsis muaj qhov zoo tshaj plaws lossis qhov tsis zoo, tsuas yog txoj cai lossis tsis ncaj ncees ntawm scene adaptation.
Cov yam ntxwv tseem ceeb thiab kev hloov pauv ntawm ob hom khoom siv
1. PTFE: qhov "tsuas yog khiav" rau qhov kawg RF kev ua tau zoo
Qhov poob qis ntawm PTFE yog qhov txiaj ntsig zoo ntawm nws cov qauv molecular: carbon fluorine daim ntawv cog lus ruaj khov heev, thiab cov polarization poob zoo li xoom. Hauv cov xwm txheej xws li millimeter nthwv dej thiab kev sib txuas lus satellite qhov twg "txhua 0.1dB poob ncaj qha txiav txim siab seb lub kaw lus puas tuaj yeem ua haujlwm", nws yuav luag yog qhov kev xaiv tsis tuaj yeem hloov.
Cov txiaj ntsig tseem ceeb: Kev poob qis heev thoob plaws txhua qhov ntau zaus, qhov tsawg kawg nkaus Dk kub drift, thiab yuav luag tsis muaj qhov cuam tshuam ntau zaus hauv qhov kub thiab txias, ua rau nws qhov kev ua tau zoo rau cov xwm txheej ultra-high zaus saum 20GHz.
Congenital shortcomings: tsis tshua muaj zog saum npoo, nyuaj sib txuas nrog tooj liab ntawv ci thiab fiberglass daim ntaub, tsis tshua muaj yield ntawm multi-layer lamination, thiab tsis tshua muaj nqi siab ntawm kev siv complex qauv xws li faus muaj peev xwm thiab faus tsis kam.
Kev hloov kho qhov xwm txheej: tus nqi siab, me me, thiab kev ua haujlwm tseem ceeb xws li millimeter yoj radar saum 77GHz, qis orbit satellite phased array antennas, 5G hauv paus chaw nres tsheb RF amplifier boards, thiab tub rog radar pem hauv ntej-kawg.
2. Carbon hydrogen resin: "engineering pom kev daws teeb meem" rau huab hwm coj ntau lawm nqi-zoo
Cov pa roj carbon hydrogen resin tag nrho tawm ntawm lub tswv yim ntawm "imitating PTFE kev ua tau zoo", thiab cov tub ntxhais yog coj lub manufacturability ze rau FR-4 qib thaum muab ib co poob redundancy, daws qhov mob taw tes ntawm loj-scale zus tau tej cov high-frequency boards.
Cov txiaj ntsig tseem ceeb: Tsis tas yuav tsum muaj kev kho tshwj xeeb ntawm qhov chaw ua haujlwm, thiab cov kab ntau lawm PCB tuaj yeem ua haujlwm ncaj qha, nrog cov txiaj ntsig siab thiab lub sijhawm xa khoom ruaj khov. Lub compression tawm los ntawm ntau txheej boards (8 lossis ntau txheej) yog siab dua PTFE, thiab tus nqi kom zoo dua yog qhov tseem ceeb.
Kev ua tau zoo ciam teb: Hauv cov zaus band hauv qab 10GHz, nws qhov kev ua haujlwm poob tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm feem ntau ntawm cov ntaub ntawv kev sib txuas lus thiab cov xwm txheej tsheb, thiab yuav tsis muaj teeb liab txuas txuas.
Kev hloov kho qhov xwm txheej: Cov nplai loj, tus nqi rhiab xws li 5G nruab nrab mus rau qis zaus hauv paus chaw nres tsheb boards, theem kev lag luam hloov siab ceev backboards, 24G tsheb radar, AI servers nrog 224Gbps high-speed txuas, thiab lwm yam.
Lub hauv paus kev txiav txim siab logic rau customized khoom xaiv ntawm high-frequency boards
Lub ntsiab lus ntawm kev xaiv tsis yog los sib piv qhov tsis sib xws, tab sis kom phim cov ntaub ntawv rov qab nrog peb qhov teeb meem tseem ceeb kom tsis txhob "kev ua haujlwm ntau dhau los siv nyiaj" lossis "kev ua haujlwm tsis txaus":
Thawj daim npav zaus pib: Nyob rau hauv cov xwm txheej uas qhov kev khiav hauj lwm zaus tshaj 20GHz thiab muaj cov kev cai nruj heev rau kev poob / rov qab poob, PTFE yog tib txoj kev daws teeb meem; Hauv cov xwm txheej hauv qab 10GHz nrog cov peev nyiaj poob qis, qhov txiaj ntsig zoo ntawm hydrocarbon resins yuav ua kom tsis muaj zog.
Saib ntawm qhov nyuaj ntawm cov qauv dua: rau cov phaj nyuaj nrog ntau dua lossis sib npaug ntawm 8 txheej thiab qhov xav tau rau qhov muag tsis pom kev faus qhov / faus resistors, cov txheej txheem kev sib raug zoo ntawm hydrocarbon resin yuav txo qhov kev pheej hmoo ntawm kev tsim tawm ntau; 2-4 txheej yooj yim RF board, kev ua haujlwm nyuaj ntawm PTFE yog tswj tau tag nrho.
Thaum kawg, suav cov nplai ntau lawm: me me batch customized RF prototypes, nrog rau qhov tseem ceeb muab rau PTFE los xyuas kom meej kev ua tau zoo; Rau kev txiav txim ntau tshaj 100000 lub tsheb specifications / cov ntaub ntawv kev sib txuas lus, hydrocarbon resin tuaj yeem compress tus nqi ntawm ib lub rooj tsavxwm rau ib feem peb ntawm PTFE, thaum txo lub sijhawm xa khoom ntau dua ib nrab.
