Ibhodi lesifunda eliphrintiwe leMicrowave futhi i-RF PCB idinga ukuthintwa okukhethekile okungenzeka ukuthi abalingani bakho bokukhiqiza abavamile bangakwazi ukubamba. Singasebenzisa ama-laminates aphakeme ngokuqondisa okuqinile nokulawulwa kwekhwalithi ephezulu ukuklama kahle nokuthuthukisa i-RF PCB yakho ukuqinisekisa ukusebenza okujwayelekile.

URayming ube ngumphakeli ohola phambili we-RF microwave PCB emhlabeni, egxile kuma-laminates e-HF PCB. I-Rogers PCB, i-Teflon PCB, i-Arlon PCB, ngikwazi ukwenza izinto ozidingayo.

I-RF PCB

< p> Ungathembela kwimikhiqizo yobungcweti kaRayming ngoba sineqembu, amathuluzi kanye nesipiliyoni sokuphatha izinto ezinamaminerali ezinezidingo ezikhethekile ezihlobene nokukhanda, ukushisa, ugesi nezinye izici ezithile zokusebenza ezingaphezulu kwezinto ezijwayelekile ze-FR-4.

Beka imikhiqizo yakho ezandleni eziphephile ngokuthembela kumhlinzeki we-rf microwave PCB ophezulu ogxile kuzidingo eziqinile zokubekezelela futhi ahambise ukwesekwa okudingayo ngesikhathi, ngaso sonke isikhathi.

Qonda ukuthi yini i-hf PCBS,

1. I-Hf PCBS noma ushayele i-microwave PCBS / i-RF PCBS / i-RF PCBS isetshenziswa kakhulu kwezokuxhumana okungenazintambo, amanethiwekhi angenantambo kanye nokuxhumana nge-satellite, ikakhulukazi amanethiwekhi we-3G, okwandisa isidingo semakethe semikhiqizo ku-HF PCBS. Namuhla, isidingo semiklamo ye-microwave material PCB siyakhula, futhi ukufinyelela kwedatha okungenazintambo (ama-high-frequency) ukufinyelela ngokushesha kuba yisidingo sezimakethe eziningi ezifana nezokuvikela, i-aerospace kanye namanethiwekhi weselula. Izidingo zemakethe ezishintshayo ziyaqhubeka nokuqhuba ukuthuthukiswa kwamabhodi wesifunda aprintiwe kaningi. Njengamarediyo ama-microwave angama-50 + GHz noma amasistimu omoya okuvikela, angabamba ne-PCBS engena-halogen.

2. I-RF PCB & Imvamisa ephezulu ye-PCBS eyenziwe nge-polytetrafluoroethylene (i-PTFE PCB), ama-fluoropolymers agcwaliswe ngobumba noma izinto ezigcwaliswe ngobumba ze-hydrocarbon thermosetting izinto ezinezakhiwo ezithuthukisiwe zedielectri. Okokusebenza kunokuhlala okuphansi kwe-dielectric okungu-2.0-3.8, ukulahleka okuphansi kwesici kanye nezici ezinhle kakhulu zokulahleka, kepha futhi kunokusebenza okuhle, izinga lokushisa lengilazi eliphakeme, izinga eliphansi kakhulu le-hydrophilic, ukuzinza okuhle kakhulu kokushisa. I-coefficient yokunwetshwa kwezinto ze-PTFE PCB ifana naleyo yethusi, okwenza ukuthi okuqukethwe kube nokuzinza okuhle kakhulu.

I-3.Panda PCB Inkampani inyuse imishini yokukhiqiza kanye nokutshalwa kwezimali kwe-r & d. Kule minyaka embalwa edlule emkhakheni wokuthuthukiswa kwe-HF PCB, kumakhasimende avela emhlabeni wonke ukuhlangabezana nentuthuko yemakethe ye-RF PCB, sinolwazi oluningi ekwakhiweni kwe-PTFE PCB yezinhlobo zamabhodi e-HF, angathuthela ngokushesha kumzekelo nokukhiqizwa kwevolumu. Abahlinzeki bethu be-teflon abajwayelekile bafaka: i-Rogers PCB, i-Nelco PCB, i-Taconic PCB, i-Arlon PCB.

Umhlahlandlela ojwayelekile kumabhodi wesifunda aprintiwe

Idizayini ye-RF neMircowave PCB

Ama-PCBS anamuhla ahlanganisa ubuchwepheshe obuhlukahlukene bedijithali nobuxubene namasiginali, ngakho-ke ukwakheka nokuklanywa kuba nzima kakhulu, ikakhulukazi lapho i-rf ne-microwave ixubene nezinto ezingaphansi. Kungakhathaliseki ukuthi usebenza nathi, omunye umthengisi we-RF PCB, noma udizayina i-RF PCB yakho, kunezinto eziningi ezibhekwayo.

Okokuqala ukuthi ububanzi bemvamisa ye-RF imvamisa buba yi-500 MHz kuye ku-2 GHz, kepha ukwakheka okungaphezu kwe-100 MHz kuvame ukubhekwa njenge-RF PCBS. Uma ungena ngaphezu kwe-2 GHz, ukusebanga lemvamisa le-microwave.

Imiklamo ye-RF ne-microwave PCB inomehluko omkhulu – umehluko phakathi kwabo nesekethe yakho ejwayelekile yedijithali noma ye-analog.

Ngamafuphi, amabhodi wesekethe aphrintiwe asebenzisa amasiginali we-analog kumaza aphezulu kakhulu emvelweni. Isiginali yakho ye-RF ingaba cishe kunoma iyiphi i-voltage neleveli yamanje nganoma yisiphi isikhathi ngesikhathi, inqobo nje uma iphakathi kwemikhawulo yakho emincane nemikhulukazi.

I-RF namabhodi wesekethe aphrintiwe e-microwave adlulisa amasiginali kumvamisa ofanayo nangaphakathi kwebhendi ethile yemvamisa. Izihlungi ze-bandpass zisetshenziselwa ukuthumela amasiginali ku- “band of interest” nokuhlunga noma yimaphi amasignali ngaphandle kwalelo banga lobubanzi. Ibhendi ingaba ncanyana noma ibanzi futhi ingasatshalaliswa ngesithwali semvamisa ephezulu.
