Inodzorwa impedance traces uye yakaderedzwa parasitic zvinhu zvinochengetedza chiratidzo chekutendeka kubva modulation IC kuenda ku LED junction.

Thermal Management Architecture

Kupisa kupisa kunopatsanura anoshanda Li-Fi PCB magadzirirwo kubva kune asina kuvimbika masisitimu. Yakakwira-frequency switching inoburitsa akakosha ekupisa ayo simbi-musimboti substrates kero kuburikidza nealuminium kana yemhangura base layer inopa 100-200 W/mK thermal conductivity maringe neFR-4's 0.3 W/mK. Thermal vias uye ndege dzakatsaurirwa kupisa-kuparadzira ndege dzinodzivirira kukwira kwekushisa kwejunction iyo inoshandura LED wavelength uye inoderedza modulation bandwidth.

Zvinhu zvakakosha zvekugadzira thermal zvinosanganisira:

• Metal-core substrate kubatanidzwa -Aluminium kana zvigadziko zvemhangura zvinopa nzira dzekupisa dzakananga kubva kuLED kuenda kunonyura.
• Strategic kuburikidza nekuisa - Thermal vias batanidza chikamu Mapedhi kune zvemukati simbi akaturikidzana kuitira kunyatsopisa kupisa kupararira.
• Ndege dzakatsaurirwa dzinopisa -Matanho emhangura anogovera mitoro yekupisa munzvimbo dzakafara kudzivirira nzvimbo dzinopisa.

Optical Alignment uye Coupling

Iyo Li-Fi PCB inochengetedza chaiyo chikamu chinzvimbo chekubatanidza optical system. Kurongeka kwekuiswa kwe LED mukati me ± 50 micrometer inogonesa kurongeka kwakaringana nemalenzi, zviratidziro, kana fiber optic interfaces inoumba uye inotungamira mwenje wemwenje wemwenje wepamusoro wekufambisa.

Dhizaini Mafungiro eLi-Fi PCB

Yakakwira-Frequency Signal Path Dhizaini

Li-Fi PCB kutapurirana mitsara inoda kudzorwa impedance pakati pe50-75 ohms zvichienderana nezvinodiwa nemutyairi.
