I-Rogers PCB
Yintoni iRogers PCB?
I-Rogers PCB yibhodi yesekethe eprintiweyo esemgangathweni ephezulu eyenziwe yiRogers Corporation. Isebenzisa izixhobo eziphambili ezifana nee-PTFE composites ezizaliswe yi-ceramic kunye nee-substrates ezisekwe kwi-ceramic ezisebenza kakuhle. Ngokungafaniyo neebhodi ze-FR-4 epoxy fiberglass eziqhelekileyo, i-Rogers PCB isusa iileya zefayibha zeglasi, nto leyo ebangela iimpawu eziphezulu eziquka i-dielectric constant ezinzileyo, ilahleko encinci yesiginali, kunye nokunyamezelana okungaqhelekanga kobushushu. Yenzelwe ngokukodwa iisekethe ezisebenza kumaza angaphezu kwe-500MHz, i-Rogers PCB ifumana ukusetyenziswa okubanzi kwii-elektroniki eziphambili, kubandakanya unxibelelwano, i-radar, kunye neenkqubo zesathelayithi.
Ulawulo oluKhethekileyo lobushushu
Amaxabiso e-Stable Dielectric Constant (Dk) aqhele ukuba phakathi kwe-2.2–3.5 (umz., RO4350B ene-Dk=3.48), eqinisekisa umahluko omncinci kwiireyithingi ezibanzi ze-frequency kwaye ivumela isantya sokudlulisa isignali nge-30% ngokukhawuleza kune-FR-4. Ukulahleka kwe-Dielectric ephantsi (Df) kufikelela kwinqanaba eliphantsi njenge-0.0013 kwi-10GHz (umz., uthotho lwe-RO3000), ephantsi kakhulu kune-0.02+ ye-FR-4, nto leyo enciphisa ukuthotywa kwesignali ephezulu. Iibhodi zikwaxhasa ulawulo lwe-precision impedance, olubalulekileyo kuyilo lwe-RF kunye noyilo lwesekethe ye-microwave.
Ukufakwa kombane okuPhezulu
Ii-coefficients zokwandisa ubushushu (i-CTE) zihambelana ne-copper foil, zithintela ukuqhekeka phantsi kobushushu obuphezulu kwaye zenze iibhodi zilungele iindawo ezinobushushu obuphezulu ezifana ne-elektroniki yeemoto kunye ne-aerospace. Ngokufunxwa kwamanzi ngaphantsi kwe-0.1%, zigcina uzinzo kwiimeko ezinomswakama ophezulu xa kuthelekiswa ne-FR-4's 0.2%–0.3%. Iimodeli ezifana ne-RO4003 zimelana nobushushu obungaphezulu kwama-280°C, zihambelana neenkqubo zokunyibilikisa ezingenalo i-lead.
Amandla kunye nozinzo lweMishini
Uthotho lweRO3000® lusebenzisa i-PTFE egcwele iseramikhi, isisombululo esingabizi kakhulu kwi-microwave yorhwebo, iimodyuli zeRF, kunye nee-antenna ze-5G base station. Uthotho lweRO4000® lune-hydrocarbon egcwele iseramikhi ukuze isebenze kakuhle kwiisekethe zedijithali ezikhawulezayo, ii-laminates ezixutyiweyo, kunye nee-avionics. Uthotho lweRT/duroid® lubonelela ngee-PTFE composites ezinokuthembeka okuphezulu kwiindawo ezixineneyo, ezifanelekileyo kunxibelelwano lwesathelayithi, iinkqubo zeradar, kunye neenqwelo moya zomkhosi. Uthotho lweTMM®, i-ceramic-thermoset polymer composite ene-Dk ephezulu, isetyenziswa kwii-antenna ze-millimeter-wave, iimodyuli zesensor, kunye nezixhobo zovavanyo lwe-HF.
I-FR-4 vs. Rogers PCB: Ungakhetha njani?
Izinto ze-FR-4 zenziwe nge-fiberglass kunye ne-epoxy resin, ene-Dk ye-4.2–4.8 enobuthathaka kumaza amaninzi, ilahleko ephezulu yesiginali (>0.02@1GHz), kunye nokwandiswa okuphezulu kobushushu, okwenza ukuba ifaneleke kwii-applications ezinobuthathaka kwibhajethi, ezinobunzima obuphantsi njenge-electronics zabathengi. Izixhobo ze-Rogers PCB zisebenzisa i-PTFE okanye ii-composites ezizaliswe yi-ceramic, kunye ne-Dk ezinzileyo (2.2–3.5), ilahleko ephantsi kakhulu (500MHz) ezifana nezikhululo zesiseko ze-5G kunye neenkqubo ze-radar. Ii-laminates ze-hybrid ezidibanisa iRogers kunye ne-FR-4 zibonelela ngokulinganisela kweendleko kunye nokusebenza.
I-Rogers PCB kwixesha le-5G
Urhwebo lwe-5G lwehlabathi luqhuba ukuphuculwa kwezakhiwo zezikhululo zesiseko zemveli (i-BBU+RRU+antenna) ukuya kwiiyunithi ze-antenna ezisebenzayo ezidibeneyo (ii-AAU), nto leyo eyonyusa imfuno yezinto ezisetyenziswa rhoqo. Ii-antenna ze-MIMO ziye zavela kwiizibuko ze-4/8 ukuya kwiizibuko ze-64/128, nto leyo enyusa ukusetyenziswa kwe-Rogers PCB kwisikhululo ngasinye sesiseko nge-4–6x. Ii-antenna zesiphelo ziyatshintsha ukusuka kwi-PI-based FPC ukuya kwizinto ze-low-Dk/Df LCP (umz., i-Apple iPhone X), ngelixa iimodyuli ze-RF zesikhululo sesiseko zixhomekeke kwi-RO4350B/RT/duroid® 5880, nto leyo enyusa iindleko zezinto nge-1.5–3x kwisikhululo ngasinye sesiseko. I-Rogers inesabelo semarike sehlabathi esingaphezulu kwe-50% kwiibhodi ze-high-frequency, kunye nezinto zayo ze-5G ezisetyenziswa kwiinkqubo ze-antenna zabavelisi bezixhobo zonxibelelwano ezinkulu.
Iingcali zeMveliso zeRogers PCBs
Ukwenziwa kwee-PCB zeRogers kufuna iinkqubo ezikhethekileyo eziquka ukubhola nge-laser, unyango lwe-CF4/O2 plasma desmear, kunye nemijikelo ye-lamination elawulwa ngokuchanekileyo (umz., ukubhaka nge-121–149°C iiyure ezi-1–2 kwi-RO4003 substrates). Sisebenzisa amava okuvelisa akhethekileyo eRogers kwiminyaka engaphezu kweshumi, indawo yethu ixhasa ipotifoliyo epheleleyo yezinto (RO3000™/RO4000™/RT/duroid®). Sinikezela ngezisombululo ezipheleleyo ukusuka kwiiprototypes ezikhawulezayo zeeyure ezingama-48 ukuya kwimveliso emincinci, sigcina ukunyamezela okungqongqo kwe-±5% kwiipropati ze-dielectric kunye nolawulo lwe-impedance kuyo yonke indawo.
