RO4000 ili ndi CTE yaying'ono ya z-axis kuti ikhale yodalirika kwambiri.
Kodi mumapewa bwanji kusokonezedwa ndi ma PCB pafupipafupi?
Zigawo zama frequency apamwamba ziyenera kuyikidwa m'njira yoti zikhale ndi zizindikiro zazifupi momwe zingathere. Ma capacitor olekanitsa (kapena odutsa) ayenera kuyikidwa pafupi momwe angathere ndi pini iliyonse yamagetsi ya zigawo zogwira ntchito, motero kuchepetsa kukwera kwa magetsi panthawi yosintha chizindikiro, ndikupewa kubwerera pansi.
Kodi PCB Yokwera Ma Frequency ndi Chiyani?
PCB yothamanga kwambiri ndi mtundu wa PCB yopangidwa mwapadera kuti igwire ntchito ndi ma signal amphamvu kuyambira pa 1 GHz ndi kupitirira apo. Imapangidwa ndi zipangizo zamagetsi amphamvu, ndipo imagwiritsidwa ntchito m'zida zambiri zomwe zimafuna kutumiza ma signal mwachangu, modalirika, kogwira mtima komanso kotsika kwambiri komanso kutetezedwa kwamagetsi kosalekeza. Kawirikawiri, ma PCB amphamvu kwambiri ndi malo ofunikira kwambiri pakukula kwa ukadaulo wamakono wolumikizirana monga 5G, kulumikizana opanda zingwe (WIFI), machitidwe a radar, ma microwave radio frequency, machitidwe a satellite, ndi zida zina zamagetsi zapamwamba kwambiri m'magawo azachipatala ndi ankhondo.
Kodi PCB yogwiritsidwa ntchito pafupipafupi kwambiri ndi chiyani komanso ubwino wake ndi ntchito zake?
Ma PCB a HF amatanthauzidwa ndi chokhazikika cha dielectric chotsika (Dk), chotsitsa dissipation factor (Df), ndi kuchuluka kochepa kwa kutentha. Amagwiritsidwa ntchito nthawi zonse paukadaulo wa HDI. Amagwiritsidwanso ntchito kwambiri pakulankhulana kwachangu, kulumikizana kwa telefoni, ndi ukadaulo wa RF microwave.
Kodi mungatani kuti chizindikiro chapamwamba chisabweretse mavuto mu PCB yanu?
Njira monga mapulaneti ogawanika, ma vias osokera, ndi kuyika nyenyezi pansi zingagwiritsidwe ntchito kuchepetsa kuzungulira kwa nthaka ndikuwonetsetsa kuti njira zoyenera zobwezeretsera zizindikiro zikuyenda bwino. Mwa kupanga mapulaneti olimba komanso otsika, opanga amatha kuchepetsa phokoso bwino ndikuwonjezera magwiridwe antchito a ma circuits apamwamba.
Kodi mumasunga bwanji umphumphu wa chizindikiro pa PCB?
Lamulo losavuta ndi kuyika zigawo zotsatizana motsatizana pa ngodya zolondola. Kugwiritsa ntchito mapulaneti apansi kuti mulekanitse zigawo zobisika ndi njira yabwino yosungira kukhulupirika kwa chizindikiro. Phokoso la magetsi ndi chinthu chofunika kwambiri ndipo chimafuna kapangidwe kake mosamala.
Kodi ntchito zomwe zimagwiritsidwa ntchito pa Rogers PCB ndi ziti?

Kodi ndingasankhe bwanji zinthu za RF PCB?
Tikamayesetsa kusankha zinthu za RF PCB, chofunika kwambiri ndikuonetsetsa kuti dielectric constant (DK) ndi dissipation factor (DF) za zinthuzo zikukwaniritsa zofunikira za ma electromagnetic frequency a zida zanu. Komanso, tiyenera kusankha zinthu zomwe zimagwiritsidwa ntchito kwambiri, monga Rogers RO4350B, RO4003C, Panasonic MEGRON 6, MEGTRON 7 ndi zina zotero.
Kodi ndiyamba bwanji ndi kapangidwe ka RF PCB?
Choyamba tiyenera kudziwa ntchito ndi momwe mapulogalamu anu amagwiritsidwira ntchito. Kachiwiri, tiyenera kupanga chithunzi. Kachitatu timapanga mafayilo a Gerber opangira ma PCB ndi mndandanda wa BOM wa ma PCB. Pomaliza, kusanthula bwino zinthu za RF PCB ndikofunikira, ndipo kudzathandiza kuti zipangizo zathu zikhale zapamwamba komanso zotsika mtengo.
Kodi PCB imasinthasintha bwanji?
Ma frequency a PCB amatha kuyambira 0HZ mpaka kupitirira 300GHZ. Nthawi zambiri timatcha kuti PCB yothamanga kwambiri ngati ma frequency a zinthu za PCB ndi ochulukirapo kuposa 30MHZ, ndipo ma frequency opitilira 3GHZ ndi okwera kwambiri.
Kodi zinthuzo ndiye chinthu chofunikira kwambiri pa RF PCB?
Inde, ndi choncho. Zipangizo za RF zomwe tasankha zidzakhudza kwambiri ntchito ya RF PCB yathu mu ntchito zathu. Komanso, kusiyana kwa mtengo ndi kwakukulu pamitundu yosiyanasiyana ya zipangizo za RF. Chifukwa chake, tiyenera kugwiritsa ntchito zipangizo zotsika mtengo kwambiri kuti tikwaniritse zosowa zathu zama electromagnetic frequency.
Kodi kusiyana pakati pa RF PCB ndi PCB wamba ndi kotani?
RF PCB iyenera kupangidwa ndi zinthu zama frequency apamwamba kuti ikwaniritse zofunikira zotumizira ma signal. Koma PCB yokhazikika imapangidwa ndi zinthu wamba za FR4 kuti ikwaniritse ntchito zamagetsi pambuyo pokhazikitsa PCB.
Kodi kusiyana pakati pa RF ndi microwave ndi kotani?
RF ndi chidule cha ma frequency a wailesi. RF ndi microwave zonse ndi ma frequency afupiafupi a mafunde amagetsi komanso ma frequency apamwamba. Kusiyana kwakukulu pakati pa RF ndi microwave ndi ma frequency osiyanasiyana. RF imayambira pa 30MHZ mpaka 300GHZ, ndipo microwave imayambira pa 1GHZ mpaka 100GHZ.
