Kunzwisisa WiFi 7 uye Impact Yayo paPCB Dhizaini yeVagadziri veMagetsi

WiFi 7, inozivikanwawo seIEEE 802.11be (Yakanyanya High throughput), ndicho chizvarwa chiri kuuya cheWi-Fi tekinoroji inovaka pamusoro pehwaro hweWiFi 6. Inosuma matekinoroji akati wandei ane chinangwa chekusimudzira kufambiswa kwedata uye kuderedza kunonoka. Kufambira mberi uku kunosanganisira kuitwa kwe320 MHz bandwidth, 4096-QAM (Quadrature Amplitude Modulation), akawanda resource unit (MRU) tsigiro, akawanda-link mashandiro (MLO), uye yakawanda-yekuwanika nzvimbo (AP) kurongeka. Nemagadzirirwo aya, WiFi 7 inotarisirwa kutsigira kumhanya kwekufambisa kunosvika 23 Gbps, kanenge katatu nekukurumidza kupfuura WiFi 6.

Sei tichida WiFi 7?

Kudiwa kweWiFi 7 kunobva mukutsamira kuri kuwedzera kune isina waya network yeakakwira-bandwidth maapplication munzvimbo dzese dzekugara uye dzebhizinesi. Zvishandiso zvemazuva ano senge 4K uye 8K vhidhiyo kutenderera, chaiyo chaiyo (VR), online mutambo wemitambo, uye gore komputa inoda yakakwira throughput uye yakaderera latency pane yazvino zviyero zvinogona kupa. Nepo WiFi 6 yakaita kuvandudzwa kwakakosha munzvimbo idzi, zvinodiwa zvetekinoroji dziri kusimukira zvinoda kuvandudzwa kweWiFi 7 kuti ipe ruzivo rwepamusoro mushandisi.

Zvinhu zvakakosha zveWiFi 7

• Mitengo Yepamusoro yeData : WiFi 7 inovimbisa mitengo yedata inosvika 46 Gbps, kukwira kukuru kubva pa9.6 Gbps inopihwa neWiFi 6. Izvi zvinoitwa kuburikidza nebandwidths yakakura inosvika 320 MHz uye kushandiswa kwezvirongwa zvepamusoro zvemodulation.

• Kushanda Kwakavandudzwa KwemaLinki Akawanda (MLO) : WiFi 7 inoisa MLO, iyo inobvumira zvishandiso kutumira nekugamuchira data panguva imwe chete kuburikidza nemabhendi akawanda emafrequency (2.4 GHz, 5 GHz, uye 6 GHz). Izvi zvinowedzera kushanda zvakanaka kwenetwork uye zvinoderedza kuzara kwedata.

• Kubudirira Kwakawedzerwa kweSpectrum : Nekushandiswa kwe4096-QAM (Quadrature Amplitude Modulation), WiFi 7 inogona kunyora data rakawanda mukati mespectrum imwe chete, zvichivandudza kushanda zvakanaka kwespectral.

• Kunonoka Kwakaderera uye Kuvimbika Kwakakwirira : WiFi 7 ine chinangwa chekusvitsa kunonoka kwakaderera kusvika 1 millisecond, izvo zvakakosha kumapurogiramu anoda kutaurirana panguva chaiyo, senge mitambo yemitambo uye otomatiki yeindasitiri.

• Kuvandudzwa kweTarget Wake Time (TWT) : TWT muWiFi 7 yakagadziriswa kuti ideredze kushandiswa kwesimba, zvichiita kuti ive yakakodzera midziyo yeIoT inoshandisa bhatiri.

Zvinorehwa nePCB Dhizaini neWiFi 7

Iko kufambira mberi muWiFi 7 kunounza akati wandei matambudziko nemikana yePCB vagadziri uye vagadziri vemagetsi. Kufunga kwakakosha kunosanganisira yakakwira-frequency dhizaini, yekupisa manejimendi, kutendeseka kwesimba, uye chikamu chekuisa uye nzira.

High-Frequency Design

WiFi 7 inoshanda nepamusoro-soro, ichida chaiyo yakakwira-frequency PCB dhizaini maitiro. Izvi zvinosanganisira kuchengetedza inodzorwa impedance kuve nechokwadi chekuvimbika kwechiratidzo nekusarudza zvinhu zvine yakagadzikana dielectric constants uye yakaderera kurasikirwa tangents. Pamusoro pezvo, kuve nechokwadi chekurasika kushoma kwechiratidzo uye kutarisisa kunoda kunyatsoronga marongero, senge kwakaringana hupamhi hwekutevera uye nzvimbo uye kushandiswa kweakasiyana mapeya. Nzira dzinoshanda dzekutarisira kupisa dzakakosha nekuda kwekuwedzera kwekupisa kwemafuta kubva kune yakakwirira data data uye akawanda-link mashandiro. Aya marongero anosanganisira kupisa kuburikidza nearrays ekubvisa kupisa kubva kune zvakakosha zvinhu uye kubatanidza kupisa kunonyura uye mapedhi ekupisa kuwedzera kupisa kupisa.

Simba Kutendeseka uye Chikamu Kuiswa

Kuchengetedza simba rakasimba kwakakosha nekuda kwezvinodiwa nesimba reWiFi 7. Izvi zvinosanganisira kugadzira network yekugovera simba yakagadzikana uye isina ruzha (PDN) uye kuisa macapacitor ekuparadzanisa simba kuti kuderedze ruzha rwemagetsi. Kuisa zvikamu zvakanaka uye nzira yekufambisa zvinhu zvakakoshawo pakuderedza kuora kwechiratidzo uye kupindira kwemagetsi ( EMI ). Izvi zvinogona kuitwa nekuchengeta zviratidzo zvechiratidzo zviri pedyo uye zvakananga kuderedza kuderera kwechiratidzo uye kuisa mapuraneti epasi akasimba kuti ape nzira yekudzoka kwezviratidzo uye kuderedza EMI.

Kugadzira Kufunga kweWiFi 7 PCBs

Kune vanogadzira zvemagetsi, kutora tekinoroji yeWiFi 7 inosanganisira akati wandei makiyi ekugadzira maitirwo kuti ave nechokwadi chekushanda kwakakwana uye kuvimbika.

Kusarudzwa Kwezvinhu

Kusarudza zvinhu zvePCB zvakakodzera zvinogona kubata mafrequency akakwira uye zvinhu zvinopisa zvakanyanya kukosha. Zvinhu zvakaita se specialty low-loss laminate, specialty low-loss laminate uye Isola IS620 isarudzo dzakakurumbira nekuda kwehunhu hwazvo hwemagetsi hwakanaka uye mashandiro azvo ekupisa. Zvinhu izvi zvakakosha pakuchengetedza kusimba kwechiratidzo uye kugadzirisa huwandu hwezvinhu zvinopisa zvine chekuita netekinoroji yeWiFi 7.

Advanced Fabrication Techniques

Kugadzira maPCB eWiFi 7 kunoda matekiniki epamusoro ekugadzira. Microvia ne blind/detention kuburikidza netekinoroji zvinobatsira mukuderedza kureba kwenzira dzemasaini uye kuvandudza kusimba kwechiratidzo. Magadzirirwo e -high-density interconnect (HDI) akakoshawo pakugadzirisa huwandu hwakawanda hwezvinhu uye maconnections, zvichiita kuti maPCB akwanise kutsigira kugona kweWiFi 7.

Kudzora Kwemhando uye Kuedzwa

Maitiro ekudzivirira hunhu uye ekuyedza akakosha kuti pave nechokwadi chekuti maWiFi 7 PCB akavimbika. Otomatiki Optical Inspection ( AOI ) inoshandiswa kuona zvikanganiso zvekugadzira, ukuwo X-ray inspection inoshandiswa pakuongorora mavias akavanzwa uye ma layers emukati. Kuyedza magetsi kwakakosha pakusimbisa kuvimbika kwemasaini uye mashandiro, kuve nechokwadi chekuti maPCB anosangana nezvinodiwa zveWiFi 7 tekinoroji.

WiFi 7 Application Scenarios

Iko kukwidziridzwa kugona kweWiFi 7 kunovhura huwandu hwezvitsva zvekushandisa mumaindasitiri akasiyana siyana. Semuenzaniso, mumunda wehutano hwehutano, WiFi 7 inogona kutsigira chaiyo-nguva telemedicine mapurogiramu ane yepamusoro-tsanangudzo yevhidhiyo kutenderera uye yakaderera-latency data kutapurirana. Mune maindasitiri IoT (Internet Yezvinhu) maapplication, WiFi 7 inogona kugonesa kutaurirana kwakanaka pakati pezvinonzwa, actuators, uye kutonga masisitimu, kuvandudza otomatiki uye kugona. Pamusoro pezvo, munzvimbo yevatengi, WiFi 7 inogona kuburitsa isina musono, yemhando yepamusoro multimedia zviitiko, senge 8K vhidhiyo kutenderera uye inonyudza VR mitambo.

mhedziso

WiFi 7 inomiririra kusvetuka kwakakosha kumberi mune isina waya networking tekinoroji, ichipa kukurumidza kumhanya, yakaderera latency, uye yakagadziridzwa kushanda zvakanaka kana ichienzaniswa neyakapfuura zviyero. Iine maficha epamberi uye kugona, WiFi 7 yakagadzirira kushandura kutaurirana kusina waya uye kugonesa nguva itsva yekubatanidza kune dzakasiyana siyana dzekushandisa uye maindasitiri.
