I-RF PCB
Ukuze kuhlangatshezwane nezidingo ezikhulayo zama-Microwave & RF Printed Circuit Boards kumakhasimende ethu emhlabeni wonke, sandise utshalomali lwethu kule minyaka embalwa edlule ukuze sibe ngabakhiqizi bezinga lomhlaba lama-PCB sisebenzisa ama-laminate aphezulu kakhulu.
Lezi zinhlelo zokusebenza zivame ukudinga ama-laminate anezici ezikhethekile ezisebenza ngogesi, ezishisayo, ezisebenza ngomshini, noma ezinye ukusebenza ezidlula lezo zezinto ezijwayelekile ze-FR-4. Ngeminyaka yethu eminingi yokuhlangenwe nakho nge-PTFE-based microwave laminate, siyaqonda ukuthembeka okuphezulu kanye nezidingo zokubekezelelana okuqinile kwezicelo eziningi.
PCB Material Ukuze RF PCB
Ngabe zonke izici ezahlukahlukene zalo lonke uhlelo lokusebenza lwe-RF PCB, sithuthukise ukubambisana nabaphakeli bezinto ezisemqoka njengoRogers, Arlon, Nelco, noTaconic ukubala nje abambalwa. Yize izinto eziningi zikhethekile kakhulu, sinesitoko esikhulu somkhiqizo endaweni yethu yokugcina impahla evela kwaRogers (4003 & 4350 series) kanye no-Arlon. Aziziningi izinkampani ezikulungele ukwenza lokho uma kubhekwa izindleko eziphakeme zokuthwala impahla ukuze zikwazi ukuphendula ngokushesha.
Amabhodi wesekethe aphezulu wezobuchwepheshe akhiwe ngama-laminate wemvamisa ephezulu kungaba nzima ukuklama ngenxa yokuzwela kwezimpawu nezinselelo zokuphatha ukudluliswa kokushisa okushisayo kuhlelo lwakho lokusebenza. Izinto ezisezingeni eliphakeme kakhulu zemvamisa ye-PCB zinokuqhuba okuphansi kokushisa uma kuqhathaniswa nezinto ezijwayelekile ze-FR-4 ezisetshenziswa kuma-PCB ajwayelekile.
Izimpawu ze-RF nezama-microwave zizwela kakhulu emsindweni futhi zinokubekezelelana okuqinile kwe-impedance kunamabhodi wesifunda edijithali. Ngokusebenzisa amapulani womhlaba nokusebenzisa i-bend bend evulekile emikhondweni elawulwa yimpedance kungasiza ukwenza ukwakheka kwenziwe ngendlela esebenza kahle kakhulu.
Ngoba ubude besikhathi sesekethe buxhomeke kumvamisa futhi buxhomeke ezintweni ezibonakalayo, izinto ze-PCB ezinamanani aphezulu we-dielectric njalo (Dk) angaholela kuma-PCB amancane njengoba ukwakheka kwesektha miniaturize kungasetshenziselwa impedance ethile kanye nobubanzi bemvamisa. Imvamisa ama-laminates aphezulu we-Dk (Dk ka-6 noma ngaphezulu) ahlanganiswa nezindleko eziphansi ze-FR-4 zokwakha imidwebo ye-hybrid multilayer.
Ukuqonda ukulingana kokunwetshwa okushisayo (i-CTE), i-dielectric njalo, i-coefficient eshisa, ukushisa kokushisa kwe-dielectric constant (TCDk), factor dissipation (Df) kanye nezinto ezifana nokuvunyelwa okuhlobene, nokulahleka kwezinto ze-PCB ezitholakalayo kuzosiza i-RF PCB umklami enza umklamo oqinile ozodlula okulindelekile.
Amandla Wide Wide
Ngokungeziwe kuma-Microwave / RF PCB ajwayelekile amakhono ethu asebenzisa ama-PTFE laminates afaka futhi:
Ama-Hybrid noma ama-Mixed Dielectric Boards (inhlanganisela ye-PTFE / FR-4)
I-PCB Esekelwa Nensimbi
Amabhodi eCavity (Ama-Mechanical ne-Laser Drilled)
I-Edge Plating
Ama-Constellations
I-PCB Yesakhiwo Esikhulu
Izimpumputhe / Ukungcwatshwa kanye ne-Laser Via's
Igolide Elithambile ne-ENEPIG Plating
Insimbi Okuyinhloko I-PCB
Ibhodi Yesekethe Eliphrintiwe Lensimbi (i-MCPCB), noma i-PCB eshisayo, luhlobo lwe-PCB olunempahla yensimbi njengesisekelo salo sokusabalalisa ukushisa kwebhodi. Inhloso yengqikithi ye-MCPCB ukuqondisa kabusha ukushisa kude nezakhi zebhodi ezibucayi nezindawo ezingabalulekile kangako njengokusekelwa nge-heatsink yensimbi noma umnyombo wensimbi. Izinsimbi eziyisisekelo ku-MCPCB zisetshenziswa njengenye indlela yamabhodi we-FR4 noma we-CEM3.
Metal Core PCB Izinto kanye Ubukhulu
Ingqikithi yensimbi ye-PCB eshisayo ingaba yi-aluminium (i-aluminium core PCB), ithusi (i-PCB eyinhloko yethusi noma i-PCB yethusi esindayo) noma ingxube yama-alloys akhethekile. Okuvame kakhulu yi-PCB esemqoka ye-aluminium.
Ubukhulu bezinsimbi zensimbi kumacwecwe esisekelo se-PCB imvamisa kungama-30 mil - 125 mil, kepha amapuleti amakhulu futhi azacile kungenzeka.
Ubukhulu bocingo lwe-MCPCB lungaba yi-1 - 10 oz.
Izinzuzo ze-MCPCB
Ama-MCPCB angaba lusizo ukuwasebenzisela ikhono lawo lokuhlanganisa ungqimba we-dielectric polymer onomswakama ophezulu oshisayo wokumelana nokushisa okuphansi.
I-Metal core PCB idlulisa ukushisa okuphindwe kasishiyagalombili kuye kwayi-9 kunama-PCB e-FR4. I-MCPCB laminates ihlakaza ukushisa, igcina ukupholisa okukhiqiza izinto kupholile okuholela ekwandeni kokusebenza nempilo.
