Backplane PCB Architecture

Kugadzira PCB yekumashure kunotanga nekunyatso batanidza kuronga, kunosanganisira kutsanangura mareti e data, bandwidth zvinodiwa, uye mapuroteni ekutaurirana anotsigirwa. Protocols sePCIe, Ethernet, kana mabhazi evaridzi anosarudzwa zvichienderana nehurongwa hwekuita zvinodiwa. Yakadzama bandwidth ongororo inotaridza huwandu hwenzira uye chiteshi hunyanzvi hunodiwa kuti data ifambe zvakanaka. Pamusoro pezvo, vagadziri vanomisikidza iyo yekubatanidza topology, senge point-to-point kana nyeredzi masisitimu, kukwirisa kutaurirana pakati pemamodule uku uchichengetedza chiratidzo chechiratidzo nekumhanya kwakanyanya.

Sarudzo yekubatanidza chimwe chinhu chakakosha chebackplane PCB architecture. High-speed masisitimu inoda maatanidzi anokwanisa kutsigira data reti inodarika 25 Gbps, ine yakasimba madhizaini madhizaini ekushingirira kuisirwa kazhinji nekubvisa. High-density press-fit kana elastomeric connectors inowanzosarudzwa nekuda kwekusimba uye kushanda kwenzvimbo. Uyezve, ma-impedance-anoenderana majoini uye kudzivirira kwakakosha kuchengetedza chiratidzo chechiratidzo uye kuderedza kukanganiswa kwemagetsi (EMI), kuve nechokwadi chekuita kwakavimbika munzvimbo dzinodiwa senharembozha kana nzvimbo dzedata.

Iyo slot kumisikidza uye fomu factor inotsanangura chimiro chemuviri chebackplane redunhu bhodhi. Slots dzinofanirwa kuve dzakapatsanurwa zvine hungwaru kuti dzigadzike makadhi emwanasikana uku uchiona kufefeterwa kwemhepo kwakakwana kwekutonga kwekupisa. Yakamisikidzwa mafomu zvinhu zvakaita seATCA, CompactPCI, kana VMEbus inowanzoshandiswa kuve nechokwadi kuenderana nearipo chassis dhizaini, nepo mafomu emhando zvinhu akagadzirirwa hunyanzvi kunyorera. Kurongeka kwakaringana kwemaslots uye zvibatanidza zvinoderedza kureba kwechiratidzo, kunoderedza kuomarara kwenzira, uye inova nechokwadi chekubatanidza isina musono nezvimwe zvikamu zvehurongwa. Uku kuronga kwekuvaka kunogonesa scalable, high-performance Backplane PCBs dzakarongedzerwa kune zvinodiwa zvemazuva ano emagetsi masisitimu.

Mafungiro eMakuru-Format Backplane PCBs

Mune mamwe maapplication, zviyero zvebackplane PCBs zvinogona kudarika izvo zveyakajairwa maPCB, kunyanya mumasisitimu epamusoro-soro senge telecommunications switch, data center server, uye maindasitiri otomatiki mapuratifomu. Yakakura-fomati Backplane PCBs inodiwa kuti igare yakawedzera nhamba yezvitsvedza, zvinobatanidza, uye zvinongedzo. Nekudaro, dhizaini yavo nekugadzira zvinounza akasarudzika matambudziko, zvinoda hunyanzvi matekiniki uye zvigadzirwa kuti ive nechokwadi chekushanda kwakakwana uye kuvimbika.
