ziviso

Kuendeswa kwechishanu-chizvarwa isina waya network kwakanyatso shandura yakadhindwa yedunhu bhodhi dhizaini zvinodiwa. Sezvo masisitimu e5G achishanda pakuwedzera kuomarara frequency spectra kubva ku-sub-6GHz kuenda kumamita-wave mabhendi, kudiwa kweyepamusoro interconnect mhinduro kwakawedzera. 5G HDI PCB tekinoroji inogadzirisa matambudziko aya kuburikidza nepamusoro-density yekubatanidza, chaiyo impedance control, uye yakagadziridzwa masaini ekuisa zvivakwa ayo akajairwa mabhodhi akawanda haakwanise kuwana.

Mabhodhi edunhu akadhindwa ane density yakakura anogonesa miniaturization uye kuvandudzwa kwekushanda kwakakosha kune maRF modules emazuva ano. Kuburikidza nema microvias, fine-pitch traces, uye sophisticated layer stackups, madhizaini e5G HDI PCB anotsigira hunhu hwakasimba hwemagetsi hunodiwa pakutumira data nekukurumidza kwegigabit ukuwo achichengetedza kuvimbika kwesignali munzvimbo dzakasiyana-siyana dzema frequency.

Nei 5G RF Modules Inoda HDI PCB Technology

Frequency Spectrum Matambudziko

Yechishanu-yechizvarwa isina waya masisitimu anoshanda pane akasiyana ma frequency mabhendi kubva pa sub-6GHz kusvika mamirimita-wave renji pa28GHz uye 39GHz. Imwe neimwe frequency bhendi inopa zvakasiyana zvinodiwa zvemagetsi zvinobata zvakananga PCB dhizaini paramita. Yakakwira-frequency masiginecha anoratidza kunzwira kwakanyanyisa kuteedzera geometry, dielectric zvivakwa, uye yekubatanidza zvimiro, zvichiita kuti yakajairika PCB tekinoroji ive isina kukwana kune yepamusoro RF zvikumbiro.

Traditional PCB Limitations

Standard multilayer mabhodhi anosangana neakakosha zvipingamupinyi zvekuita munzvimbo dzakakwirira-frequency. Kuburikidza negomba vias suma parasitic inductance uye capacitance iyo inoshatisa masaini waveforms uye kugadzira impedance discontinuities. Yakaganhurirwa routing density inodzikamisa chikamu chekuisa sarudzo, ichimanikidza marefu masaini nzira dzinowedzera kurasikirwa kwekuisa uye kukanganiswa kwemagetsi.

HDI Technology Advantages

High-density interconnect architecture inokunda zvipimo izvi kuburikidza nelaser-drilled microvias iyo inoderedza parasitic mhedzisiro uku ichigonesa mapfupi masaini nzira. RF HDI dhizaini inosanganisa zvimiro zvepamberi izvo zvinowana nzira densities isingagoneke nekudhirowa kwemuchina:

• Via-mu-pedhi kuiswa -Inobvisa stub resonances uye inogonesa yakananga chikamu kukwira pamusoro pezvinobatana.
• Fine-line kugona -Tsvaga hupamhi pasi kusvika ku50-75 microns inotsigira chaiyo impedance kudzora nekuderedzwa crosstalk.
• Sequential lamination -Inogonesa chero-layer yekubatanidza uchichengetedza chiratidzo chekuvimbika mukati mese frequency spectrum.
