TUC TU-872 SLK PCB yeHigh-Speed FR-4 Cost Control
TUC TU-872 SLK iri pakati nepakati inobatsira mukutengeserana. Iyi sisitimu yeFR-4 yakagadziriswa-epoxy inoshanda zvakanyanya yakagadzirirwa Dr/Df yakaderera pane Tg FR-4 yakajairika uku ichichengetedza kufambirana kwemaitiro eFR-4 yakagadziriswa-yakasimba, kuvimbika kwakasimba kwekupisa, kuramba hunyoro, kuwedzera kwez-axis kwakawedzerwa, kugona kurwisa CAF, kugadzikana kwemativi, uye kuwanikwa kwakafara kwekuvaka.
TUC inoratidza laminate seTU-872 SLK uye prepreg inoenderana seTU-87P SLK. Ruzivo rweveruzhinji rwunosanganisira Tg 190°C neTMA, 200°C neDSC, uye 220°C neDMA; Td 340°C; 2.3% z-axis expansion kubva pa50–260°C; T260/T288 yemaminitsi 60/20; uye Drk 3.8 neDf 0.009 pa10 GHz kuti ive nereferensi ye50% resin-content. TUC inonyora maseva, nzvimbo yekuchengetera, backplanes, line cards, HPC, telecom, base stations, routers, uye maRF application akasarudzwa.
Nzvimbo Yepakati Pakati Pezvinhu Zvakajairwa zveFR-4 nePremium Ultra-Low-Loss
FR-4 yakajairika ine Tg ine simba guru inogona kuderera kana kureba kwenzira, maitikiro, uye huwandu hwezvinobatanidza zvichikwira. Kufamba zvakananga kune chinhu chisina simba guru kunogona kugadzirisa dambudziko remagetsi asi kuwedzera mutengo, nguva yekutungamira, kuvaka kushoma, kugadzirisa kusina kujairika, uye kushanda nesimba pakuzadzisa zvinodiwa. TU-872 SLK yakagadzirirwa kuzadza mukaha: kushanda kwemagetsi kuri nani pane FR-4 inoshandiswa zvakanyanya pasina kusiya hwaro hwekugadzira hwakajairwa hwakagadziriswa.

| Nzvimbo yechiteshi/bhodhi reRF rakasarudzwa | Yakasanganiswa digital ne RF ine mwero pamwe nezvinodiwa zvekuvimbika. | Shandisa frequency-specific modeling; usafungidzira kukodzera kwemmWave kubva ku "RF" pane runyorwa rwemaapplication. |
Mitemo yekuronga inofanira kusanganiswa nemakirasi aya. Semuenzaniso, purojekiti inogona kudoma hurefu hwakanyanya hwenzira uye kuburikidza nekuverengera paTU-872 SLK yemutengo wega wega wenzira, neongororo yeSI inosungirwa kupfuura muganho. Izvi zvinodzivirira kuwedzerwa kwekunonoka kwehurongwa kuti husapedze muganho wezvinhu pasina chiziviso.
Gadzira Muenzaniso weSarudzo yeMari-Uchipesana neChannel-Margin
Muenzaniso wekushandisa mari unofanira kusanganisira zvinopfuura mutengo we laminate. Bhodhi rinodhura zvishoma ndiro rinozadzisa goho, hunhu, purogiramu, uye mashandiro ehurongwa nemutengo wakaringana. Chinhu chepamusoro chinogona kuderedza kurasikirwa asi chinowedzera mutengo wepaneru; chinhu chakachipa chingada retimers, shorter topology, extra layers, kana kuti manufacturing tolerances dzakasimba.
| Mutengo chinhu | Mashandisiro anogona kuita TU-872 SLK | Zvekuverenga nhamba |

Kupfuura kweImpedance hakusi kupasa kurasikirwa
Kuponi yeTDR inogona kusangana ne impedance nepo mutsetse wacho uine kurasikirwa kwakanyanya kwekupinza kubva pamusoro pemhangura isina kurongeka kana imwe Df yakagadzirwa. Kune makirasi enzira anotsigira TU-872 SLK, sanganisira kuponi yemutsetse wekutumira kana imwe bvunzo yekurasikirwa yakabatana muchinyorwa chekutanga.
Backdrill uye vias
Sarudzo yezvinhu zvepakati-tier inorasika kana zvimedu zvakasara zvikanyanya. Tsanangura divi rekumashure , chimedu chakasaririra chakanangwa, tolerance, pad clearances, drill wander, uye verification. Gadzirisa return vias uye reference-plane transitions pakuchinja kwega kwega kwe high-speed layer.
Uchapupu hweChinyorwa Chekutanga hweChinhu Chinokurumidzisa "Zvakanaka"
Nyaya yekutanga inofanira kuratidza kuti mutengo wakaderera une mukana wakakwana wekuchinja kwezvigadzirwa. Kuponi imwe chete haina kukwana kutsigira sarudzo yekuti "yakanaka zvakakwana".
