Izinto Ezibalulekile Ezisetshenziswa kuma-PCB weMicrowave: Umbono Wezobuchwepheshe

Ukusebenza kwe-Microwave PCB kunqunywa ngokuyisisekelo izinto ezisetshenziswayo, njengoba zithonya ngokuqondile ukusakazwa kwesignali, izici zokulahlekelwa, nokuzinza kwe-thermal. Amasignali amaza aphezulu abeka izidingo eziqinile ku-dielectric constant (Dk), dissipation factor (Df), kanye nokusebenza okushisayo kwezinto. Ngezansi, sijula ​​ekujuleni kobuchwepheshe bokukhethwa kwempahla yama-Microwave PCBs:

1. I-PTFE (i-Polytetrafluoroethylene): Ukusebenza Kwe-Dielectric Okuhlanzekile Okuphakeme

Ngokwakhiwa kwe-PTFE okunokulahlekelwa okuncane kakhulu, ukukhiqizwa kwe-PCB ye-laminate ephansi esuselwa ku-PTFE ihlolwa kusukela ekuqoqweni okuphelele, ukwelashwa ngethusi, ngesakhiwo, kanye nezindlela zokwamukelwa kwe-RF.

I-PTFE, evame ukwaziwa ngegama lomkhiqizo i-Teflon, iyindinganiso yegolide yama-PCB emvamisa ephezulu ngenxa yokungaguquguquki kwayo kwe-ultra-low dielectric (ephansi njengo-2.1) kanye nokusebenza okuhlukile kokulahlekelwa kwesignali. Nokho, ukusebenza ne-PTFE kwethula izinselelo ezibalulekile zokukhiqiza:

• Ukuzinza kweDimensional: I-PTFE ijwayele ukonakala ngaphansi kwengcindezi nokushisa, okudinga amasu okucubungula akhethekile afana nokulawulwa kwe-lamination ngaphansi kwengcindezi ephezulu.
• Surface Ukwelashwa: I-PTFE ngokwemvelo ayinamatheli, ngakho-ke ingaphezulu layo kufanele liphathwe (isb., ukuchotshozwa kwamakhemikhali noma ukwenziwa kusebenze kwe-plasma) ukuze ihlangane ngempumelelo nethusi.
• I-Thermal Coefficient of Dk: I-PTFE's dielectric constant iyahlukahluka nezinga lokushisa, idinga ukumodela okunembayo kwemiklamo ezwela izinga lokushisa njengamasistimu e-radar.

2. Ama-laminate akhethekile anezinga eliphansi lokulahlekelwa: Ukulinganisela Ukusebenza kanye Nokucutshungulwa

Izakhiwo ze-microwave ezine-dielectric ephezulu zingadinga ukwenziwa kwe-PCB ye-laminate ephansi esuselwa ku-PTFE lapho isekethe idinga i-geometry ehlanganisiwe enokuziphatha kwe-dielectric okulawulwayo.

I-specialty low-loss laminate Corporation ikhiqiza ama-laminate athuthukile njenge-hydrocarbon-ceramic low-loss laminate kanye nemindeni ye-low-Dk PTFE laminate, eyenzelwe ngqo ukusetshenziswa kwe-microwave. Lezi zinto zithandwa kakhulu ngenxa yalezi zinto ezilandelayo:

• I-Loss Tangent Ephansi: I-dissipation factor (Df) ngokuvamile ingaphansi kuka-0.002, inciphisa ukuncisha isignali kumasistimu e-RF anamandla amakhulu noma amabanga amade.
• Ukusebenza Okushisayo: Ukuphatha okushisayo okuthuthukisiwe kuvumela laminates ukuthi asekele ama-amplifiers aphezulu kanye nezimpondo zesiteshi.
• Izakhiwo Ezilungele Ukuqamba: Ngokungafani ne-PTFE emsulwa, imindeni ekhethekile ye-laminate elahlekelwa kancane ihlanganisa ama-filler e-ceramic, ithuthukisa ukuzinza kobukhulu kanye nokuhambisana namasu okukhiqiza e-PCB ajwayelekile.

3. Izinhlanganisela Ezigcwaliswe Nge-Ceramic: Ngemvamisa Ephakeme Namandla

Ngomsebenzi wokuhlunga okuhlangene kanye nomsebenzi we-resonator, ukukhiqizwa kwe-PCB ye-laminate ene-DK ephezulu ephansi elahlekelwa kakhulu futhi ukukhiqizwa kwe-PCB ye-laminate ene-DK ephezulu ephansi elahlekelwa kakhulu zibuyekezwa ngokwehlukana ngoba ukujiya, ithusi, ukubopha, kanye nokulawula ukwenziwa kuthinta impendulo ye-RF eqediwe.
