I-Li-Fi kanye ne-Optical Communication LED PCBs: Izixazululo Zokudluliswa Kokukhanya Okusheshayo

Iyini i-Li-Fi PCB Technology

I-Li-Fi PCB imele isisekelo sehadiwe sezinhlelo zokuxhumana ezikhanyayo ezibonakalayo. Ubuchwepheshe be-Light Fidelity budlulisa idatha ngemithombo yokukhanya ye-LED eshintshashintshayo kumafrikhwensi ukusuka ku-MHz eminingana ukuya ngaphezulu kwe-1 GHz, engabonakali emehlweni abantu kodwa ekwazi ukuletha ukuxhumana okungenantambo kwe-broadband. I-Li-Fi PCB iguqula amasiginali wedatha kagesi ibe okokukhiphayo okushintshiwe, ifinyelele isivinini esidlula i-Wi-Fi evamile kuyilapho ingavikelekile ekuphazanyisweni kwamafrikhwensi omsakazo.

Ibhodi lesifunda eliphrintiwe lihlanganisa amasekethe omshayeli we-LED , izingxenye zokuguquguquka kwesivinini esikhulu, kanye nezinhlelo zokuphatha ukushisa zibe yipulatifomu ehlanganisiwe. Ukwakheka kwe-PCB ye-Li-Fi efanele kugcina ubuqotho besiginali kulo lonke ukuguqulwa kukagesi kuya kokukhanya ngenkathi kulawulwa ukukhiqizwa kokushisa okuvela ekusebenzeni kokushintsha okusheshayo okungalimaza ikhwalithi yokudlulisela kanye nokuthembeka kwezingxenye.

Imisebenzi esemqoka ye-Li-Fi PCB Systems

Ukushintshwa Kwesiginali kanye Nokuhlanganiswa Komshayeli

I-Li-Fi PCB ihlela ukuguquguquka okunembile kokuqina kokukhiphayo kwe-LED ukuze kufakwe ikhodi yedatha yedijithali. Ukujikeleza komshayeli kuguqula ukusakazwa kwedatha kube ukuhlukahluka kwamanje okushukumisa ama-LED ngesivinini esifinyelela kumaza we-gigahertz. Ukulandelelwa kwe-impedance okulawulwayo kanye nezinto ezincishisiwe ze-parasitic kulondoloza ukwethembeka kwesignali kusukela ekumoduliseni i-IC kuya ekuhlanganeni kwe-LED.

I-Thermal Management Architecture

Ukukhipha ukushisa kwehlukanisa imiklamo ye-Li-Fi PCB esebenzayo kumasistimu angathembekile. Ukushintsha kwe-high-frequency kukhiqiza imithwalo eshisayo ebalulekile i-metal-core substrates ebhekana nayo kusetshenziswa izendlalelo zesisekelo se-aluminium noma zethusi ezinikeza i-100-200 W/mK conductivity eshisayo uma iqhathaniswa ne-FR-4's 0.3 W/mK. Izindiza ezishisayo kanye nezindiza ezizinikele ezisakaza ukushisa zivimbela ukukhuphuka kwezinga lokushisa okuhlanganayo okushintsha ubude beza beza be-LED futhi kunciphise umkhawulokudonsa wokumodulation.

Izakhi eziyinhloko ze-thermal design zihlanganisa:

• Ukuhlanganiswa kwe-Metal-core substrate - Izisekelo ze-Aluminium noma zethusi zinikeza izindlela eziqondile ezishisayo ukusuka ku-LED kuya kusinki wokushisa.
• Isu ngokubeka - I-Thermal vias ixhuma amaphedi ezingxenyeni zensimbi zangaphakathi ukuze kusakazeke ukushisa okuphumelelayo.
• Izindiza ezishisayo ezizinikezele - Izendlalelo zethusi zisabalalisa imithwalo yokushisa ezindaweni ezibanzi ukuvimbela izindawo ezishisayo zendawo.

Ukuqondanisa kwe-Optical nokuhlanganisa

I-Li-Fi PCB igcina ukuma okunembayo kwengxenye yokuhlanganiswa kwesistimu yokubona. Ukunemba kokubekwa kwe-LED ngaphakathi kwama-micrometer angu-±50 kuqinisekisa ukuqondana okufanele namalensi, izibonisi, noma izixhumanisi ze-fiber optic ezilolonga futhi ziqondise i-modulated yokukhanya ukuze uthole ukusebenza kahle okukhulu kokudlulisela.

Ukucatshangelwa Kwedizayini ye-Li-Fi PCB

Idizayini Yendlela Yesiginali Evamile

Imigqa yokudlulisa ye-Li-Fi PCB idinga ukuthintana okulawulwayo phakathi kuka-50-75 ohms kuye ngokucaciswa komshayeli. I-Microstrip noma i-stripline geometries igcina ukungaguquguquki kwe-impedance ngokusebenzisa ububanzi bokulandelela obunembile, ukushuba kwe-dielectric, nokukhetha kwesisindo sethusi. Nge-stubs emfushane kune-wavelength yesignali engu-1/10 kunciphisa ukubonakaliswa okwehlisa ikhwalithi yokuguquguquka.

Ubuqotho bendiza ephansi buthinta ngokuqondile ukusebenza kwe-Li-Fi PCB. Izindiza eziyizethenjwa eziqhubekayo ngaphansi kokulandela amasignali zinikeza izindlela zokubuya ezinezihibe eziphansi ngenkathi zivikela ekuphazamisekeni kogesi. Ukuthunga ungqimba nge-vias esekelwe phansi njalo ngo-5-10 mm kugcina ukuqhubeka komhlaba kuzo zonke izingxenye zebhodi.

Ukukhetha Okubalulekile kwama-Optical PCB

Ukukhetha i-substrate kulinganisa ukusebenza kukagesi nezidingo ezishisayo:

• Ama-laminates we-high-frequency – i-laminate ekhethekile ephansi kokulahlekelwa noma izinto ezifanayo ezine-tangent yokulahlekelwa engaphansi kuka-0.004 kukhwalithi yesiginali yokugcina engu-1 GHz.
• I-Metal-core substrates - I-Aluminium IMS noma amabhodi e-copper-core anikezela nge-thermal conductivity izikhathi ezingama-300-500 ezinkulu kune-FR-4.
• Izinto eziguquguqukayo zePolyimide - Ukuqina kwezinga lokushisa eliphezulu kusekela ukusebenza kwe-LED ngaphezu kuka-150°C kuyilapho kuvumela ukukhweza okuvumelanayo.

Ukukhetha isiphetho sobuso kuthonya kokubili ukuhlanganisa nokuthembeka. I-ENIG ihlinzeka ngokuqina okuhle kakhulu kanye nezindawo zokubopha ngocingo ezinokumelana ne-oxidation ephakeme kakhulu. Ukuqedwa kwe-OSP kwehlisa izindleko kodwa kudinga isitoreji esilawulwayo nesikhathi sokuhlanganisa.

Ukucushwa Kwesitaki Sesendlalelo

Izitaki eziningi ze-Li-Fi PCB zinikezela izendlalelo zangaphakathi ukuze zibonise umzila ngezindiza eziphansi eziphahleni. Imiklamo yezendlalelo ezine kuya kweziyisithupha ngokuvamile yabela izendlalelo zangaphandle zokukhwezwa kwezingxenye, izendlalelo zangaphakathi zomzila olawulayo wokuvinjelwa, nezindiza ezinikelwe zokusabalalisa amandla nokuphathwa kokushisa.

Izinhlobo zokucushwa kwe-Li-Fi PCB

Amabhodi Wokudluliswa Kwedatha Yesivinini esikhulu

Imiklamo ye-Li-Fi PCB enomsebenzi owodwa ilungiselela umkhawulokudonsa omkhulu. Lawa mabhodi ahlanganisa izishayeli zokuguquguquka ezisekela isivinini sokushintsha ngaphezu kuka-100 MHz namaphakheji e-LED anamandla aphansi. Amasu esakhiwo anciphisa ubude bokulandelela phakathi kokuphumayo komshayeli ne-anode ye-LED, kunciphisa inductance ye-parasitic ekhawulela isikhathi sokukhuphuka kanye nemvamisa yokushintshashintsha okukhulu.

I-Bidirectional Transceiver Designs

Imihlangano ye-Li-Fi PCB eneduplex egcwele ihlanganisa ukudlulisa nokwamukela imisebenzi ku-substrate evamile. Ama-Photodetector array athatha izifunda zebhodi ezihlukene ezinomjikelezo ozinikele wokukhulisa i-amplification ohlukanisiwe nezishayeli zamandla aphezulu e-LED. Izindiza zaphansi ezihlukanisiwe kanye nemikhondo yokuqapha kuvimbela i-optical crosstalk kanye nokuhlangana kukagesi phakathi kwamashaneli okudlulisela kanye nokwamukela.

I-Hybrid Lighting-Communication Platforms

Izinhlelo ezimbili ze-Li-Fi PCB zihlanganisa isilawuli sokukhanyisa nokudluliswa kwedatha. Le miklamo ibhalansisa i-DC bias yamanje ekuphumeni kokukhanya ngokumelene nokujula kokumodulayo kwe-AC kumkhawulokudonsa wokuxhumana. Amasekhethi okufiphalisa ahlanganisiwe alungisa kokubili ileveli yokukhanya kanye ne-amplitude yokushintshashintsha ukuze kugcinwe amanani edatha angashintshi kuzo zonke izimfuneko zokukhanya ezihlukahlukene.

Izinselelo Zokukhiqiza Ku-Li-Fi PCB Production

Izidingo Zomhlangano Wokunemba

Umhlangano we-PCB we-Li-Fi udinga ukulawula okuqinile kokubeka kwezingxenye ezibonayo. Amasistimu wokukhetha nendawo athola ukunemba okungu-±25 micrometer okubalulekile ekuqondaneni kwe-LED kuya kumalensi. Ukuhlolwa kwe-X-ray kuqinisekisa ikhwalithi ehlanganyelwe ye-solder ngaphansi kwamaphedi e-thermal e-LED lapho okuqukethwe okungenalutho kufanele kuhlale ngaphansi kuka-25% ukuze kuqinisekiswe ukudluliswa kokushisa okwanele.

Imingcele ebalulekile yokuhlanganisa ihlanganisa:

• Ukubekezelelana kokubekwa kwengxenye - Ukuma kwe-LED kanye ne-photodetector ngaphakathi kwama-micrometer angu-±50 kugcina ukuqondanisa kwe-optical.
• Isilawuli esingenalutho solder - Ukuvalwa kwephedi eshisayo ngaphansi kuka-25% kuqinisekisa ukuqhutshwa kokushisa okusebenzayo ku-substrate.
• Ukuthuthukiswa kwephrofayela ye-reflow - Amarampu okushisa avikela izingxenye ezibucayi ze-optical ngenkathi efinyelela amalunga athembekile e-solder.

Ukubhaliswa Kwezingqimba kanye Nobuchwepheshe

Ukwenziwa kwe-Li-Fi PCB enezingqimba eziningi kudinga ukubhaliswa kwesendlalelo kuya kwesendlalelo ngaphakathi kwama-micrometer angu-±75. Ukungaqondani kahle kuphazamisa izakhiwo ezilawulwayo zokuvimbela futhi kudala ukungaqhubeki ngesikhathi soshintsho. Ama-microvias abholwe nge-laser anobubanzi obuncane obungango-0.1 mm anika amandla ukuxhumana okuminyene kuyilapho enciphisa ubude bendlela yesignali kanye nemiphumela ye-stub.

Ukungcwatshwa nokungaboni ngezakhiwo kunciphisa ibanga lomzila wesignali kodwa kwandise ubunkimbinkimbi benqubo. Nge-plating kufanele kufinyelele ukumbozwa kwethusi okufanayo okudlula ugqinsi lwama-micrometer angu-20 ukuze kuqinisekiswe ukwethembeka ngokusebenzisa amabhayisikili ashisayo kanye nokucindezeleka kwemishini.
