Rogers PCB
Menene Rogers PCB?
Rogers PCB wani allon da'ira ne mai inganci wanda Rogers Corporation ke ƙera. Yana amfani da kayan aiki na asali kamar su haɗakar PTFE da aka cika da yumbu da kuma substrates masu aiki sosai na yumbu. Ba kamar allon fiberglass na FR-4 na yau da kullun ba, Rogers PCB yana kawar da yadudduka na fiber gilashi, wanda ke haifar da halaye masu kyau waɗanda suka haɗa da tsayayyen dielectric mai dorewa, ƙarancin asarar sigina, da kuma juriyar zafi na musamman. An ƙera shi musamman don da'irori waɗanda ke aiki a mitoci sama da 500MHz, Rogers PCB yana samun aikace-aikace mai yawa a cikin kayan lantarki na zamani, gami da sadarwa, radar, da tsarin tauraron dan adam.
Gudanar da Zafin Jiki na Musamman
Ƙimar Dielectric Mai Sauƙi (Dk) yawanci tana tsakanin 2.2–3.5 (misali, RO4350B tare da Dk=3.48), tana tabbatar da ƙarancin bambanci a cikin kewayon mita mai faɗi da kuma ba da damar saurin watsa sigina da kashi 30% cikin sauri fiye da FR-4. Ƙarancin Rasa Dielectric (Df) ya kai ƙasa da 0.0013 a 10GHz (misali, jerin RO3000), ƙasa da FR-4's 0.02+, wanda ke rage raguwar siginar mita mai yawa. Allon kuma yana tallafawa sarrafa daidaiton juriya, mai mahimmanci ga ƙirar RF da da'irar microwave.
Babban Rufin Wutar Lantarki
Ma'aunin faɗaɗa zafi (CTE) yana daidaita foil ɗin jan ƙarfe, yana hana ɓarna a ƙarƙashin zagayowar zafi kuma yana sa allon ya dace da yanayin zafi mai yawa kamar na'urorin lantarki na mota da sararin samaniya. Tare da shan ruwa ƙasa da 0.1%, suna kiyaye kwanciyar hankali a yanayin zafi mai yawa idan aka kwatanta da 0.2%–0.3% na FR-4. Samfura kamar RO4003 suna jure yanayin zafi sama da 280°C, suna dacewa da hanyoyin haɗa sinadarai ba tare da gubar ba.
Ƙarfin Inji da Kwanciyar Hankali
Jerin RO3000® yana amfani da PTFE mai cike da yumbu, mafita mai araha ga microwave na kasuwanci, na'urorin RF, da eriya ta tashar tushe ta 5G. Jerin RO4000® yana da hydrocarbon mai cike da yumbu don daidaiton aiki a cikin da'irori na dijital mai sauri, laminates masu haɗaka, da avionics. Jerin RT/duroid® yana ba da haɗin PTFE mai aminci sosai don yanayi mai tsauri, wanda ya dace da sadarwa ta tauraron dan adam, tsarin radar, da sararin samaniya na soja. Jerin TMM®, haɗin polymer na yumbu-thermoset tare da babban Dk, ana amfani da shi a cikin eriya-millimeter-wave, na'urorin firikwensin, da kayan aikin gwaji na HF.
FR-4 vs. Rogers PCB: Yadda ake Zaɓa?
Kayan FR-4 sun ƙunshi fiberglass da epoxy resin, tare da Dk na 4.2–4.8 wanda ke da saurin amsawa ga mita, asarar sigina mai yawa (>0.02@1GHz), da kuma faɗaɗa zafi mafi girma, wanda hakan ya sa ya dace da aikace-aikacen da ba su da saurin amsawa ga kasafin kuɗi, kamar na'urorin lantarki na masu amfani. Kayan Rogers PCB suna amfani da PTFE ko haɗakar yumbu, tare da Dk mai karko (2.2–3.5), ƙarancin asara (500MHz) kamar tashoshin tushe na 5G da tsarin radar. Laminates masu haɗaka waɗanda suka haɗa Rogers da FR-4 suna ba da daidaiton farashi da aiki.
Rogers PCB a Zamanin 5G
Tallace-tallacen 5G na duniya yana haifar da haɓaka gine-ginen tashar tushe na gargajiya (BBU+RRU+antena) zuwa na'urorin eriya masu aiki (AAUs), wanda ke ƙara buƙatar kayan aiki masu yawan mita. Eriya na MIMO sun haɓaka daga tashoshin jiragen ruwa 4/8 zuwa tashoshin jiragen ruwa 64/128, wanda ke haɓaka amfani da Rogers PCB a kowace tashar tushe da sau 4-6. Eriya na tashar suna canzawa daga FPC mai tushen PI zuwa kayan LCP masu ƙarancin Dk/Df (misali, Apple iPhone X), yayin da samfuran RF na tashar tushe sun dogara da RO4350B/RT/duroid® 5880, wanda ke ƙara farashin kayan aiki da sau 1.5-3 a kowace tashar tushe. Rogers yana da sama da kashi 50% na kasuwar duniya a cikin allunan mita masu yawan mita, tare da kayan aikin sa na musamman na 5G da ake amfani da su a cikin tsarin eriya na manyan masana'antun kayan aikin sadarwa.
Ƙwarewar Samarwa ga Rogers PCBs
Yin ƙera Rogers PCBs yana buƙatar matakai na musamman waɗanda suka haɗa da haƙa laser, maganin CF4/O2 plasma desmear, da kuma zagayowar lamination mai kyau (misali, yin burodi 121–149°C na tsawon awanni 1-2 don substrates RO4003). Yin amfani da ƙwarewar Rogers ta musamman tsawon shekaru goma, cibiyarmu tana tallafawa cikakken fayil ɗin kayan aiki (RO3000™/RO4000™/RT/duroid®). Muna isar da cikakkun mafita daga samfuran gwaji na sa'o'i 48 zuwa iyakokin samarwa, muna kiyaye juriyar ±5% don halayen dielectric da kuma sarrafa impedance a ko'ina.
