Tsika dzekubatanidza dzakajairika mune yakakwirira-inoshanda masisitimu
Vagadziri vanowanzo edza kushandisa zvakajairwa zvinongedzo muzvigadzirwa zvavo zvekupedzisira. Vanhu vazhinji vanodudza usability kutsanangura chikonzero nei vachinamatira neyakajairwa kubva pasherufu zvigadzirwa. Dzimwe nguva, zvisinei, hapana chakajairwa chigadzirwa chinosangana nehurongwa hwekugadzira zvinodiwa uye tsika kana yakagadziridzwa yekubatanidza inosarudzwa.
Iko kushandiswa kweasina-standard ma-connectors akajairika kupfuura vazhinji vanogadzira vanofunga. Semuyenzaniso, ingangoita 25% yekutengesa kweSamtec zvinhu zvisiri-yakajairwa, kubva pazvigadziriso zvidiki zvezvigadzirwa zviripo kusvika kune zvitsva zvekubatanidza masisitimu. Zvigadzirwa izvi zvinosanganisira high-speed board-to-board (sandwich) systems, high-speed cable assemblies, backplane panels uye cable systems, maviri-piece pini uye socket systems, active cable assemblies (inonzi "mid-board optical transceivers" muSamtec's new optical guide), uye RF zvinongedzo uye tambo magungano.
Vagadziri ve-high-speed systems (112 Gb/s data rate per channel PAM4, 224 iri kuuya) yakadai se data centers, supercomputers, automated test equipment, uye imaging yezvokurapa vanowanzoshandisa high-speed cable assemblies kuendesa data yakawanda pane data yakakwirira. rates.
Kunyangwe paine akasiyana akajairwa akakwira-kumhanya tambo magungano, vatengi vazhinji vanotsanangura kugadziridzwa kune izvi zvakajairwa zvigadzirwa. Kugadziridzwa kwakajairwa kunosanganisira dhizaini yePCB yemepu yepini yezvishandiso zvakati, kuisa mabhuranzi ekudzivirira akatenderedza yakaderera-deflection twin-core tambo, kana kuwedzera mavara kune zvinobatanidza uye tambo kuti uone nhamba dzezvikamu kana kupa mirairo, kudoma mashoma emazana ezvingangoita. zvigadziriso zvinogona kuitwa.
Imwe shanduko yakakurumbira ndeyekusanganisa uye kuenzanisa iyo yekupedzisira 1 uye kupedzisa 2 zvibatanidza zvechikamu. Semuyenzaniso, iyo Flyover® QSFP-DD pamberi pepaneru yekubatanidza inogona kugumiswa kune chero nhamba yepamusoro-density end-2 zvibatanidza zvakaiswa padyo nechip. Vagadziri vanoda marudzi akasiyana-siyana ekubatanidza kumberi, kwepakati, uye kumashure mapaneru ekubatanidza masisitimu.
Kucheka-kumucheto kwepamusoro-kumhanya masisitimu kunoda chizvarwa chinotevera chepamusoro-kushanda zvibatanidza. Nekudaro, vagadziri vazhinji vari kugadzira zvimwe "zvakananga" zvikumbiro senge maindasitiri otomatiki, marobhoti, zvakamisikidzwa zvigadzirwa, uye chiono uye chekuchengetedza masisitimu. Aya mabhokisi anowanzo shandisa mamwe akakosha echinyakare anobatanidza, senge square post terminals (" zvibatanidza ") uye socket board. Iyo yakapfava dhizaini yezvigadzirwa izvi - mitsetse yepurasitiki insulators uye isiri-miniature centerlines (semuenzaniso, 2.54 kana 2.00mm ine 1.00 kana 0.80mm pitch) - inoita kuti zvigadziriso zvive nyore uye nekukurumidza, uye nekudaro zvisingadhure.
Magadzirirwo akakurumbira anosanganisira akawanda-pini polarization - kubvisa mapini - kubvumira keying, kuyerera kwemhepo, chiratidzo chemepu, uye imwe nzvimbo yekufambisa magetsi kana creepage chinhambwe uye kubvumidzwa kusangana nekuchengetedza uye zvimiro zviyero. Vazhinji vagadziri vanoshandisa bhodhi level yekubatanidza vari kuyedza kusangana neUL uye CE 61800-5-1 zvakatemwa, izvo zvinotsanangudza creepage chinhambwe uye kuremara kureba kwegiredhi rezvinhu zvakapihwa, voltage yekushandisa, uye nhanho yekusvibiswa.
Imwe gadziriso yakakurumbira ndeyekuwedzerwa kwekurongeka uye polarization maficha senge nhovo, kupinza, uye bofu plug rutsigiro, pamwe nekubatanidzwa kwesimba uye mapini echiratidzo mune imwechete yekubatanidza. Kubatanidza simba uye mapini echiratidzo mune imwechete yekubatanidza sisitimu inochengetedza PCB nzvimbo uye inovandudza kushivirira kwekufananidza mapoka ekubatanidza.
Mazhinji bhodhi-kune-bhodhi ma-connectors ane zvakanyatsogadzirwa-sign-to-ground configuration kuti awane SI (signal kutendeseka) kuita, izvo zvinoda yakaderera mode kutendeuka kuderedza radiated ruzha kana kunzwa kune ruzha. Kana kuwedzera kwekudzivirira kuita kuchidikanwa, chinongedzo chinogona kuvharirwa mune yekunze simbi shield inoputira kutenderedza iyo yese mating yekubatanidza system kudzikisa EMI uye EMC mhedzisiro.
Electroplating ndiyo imwe shanduko yakajairika; Izvi zvinosanganisira goridhe rinorema, sirivha uye palladium nickel, pakati pezvimwe. Vazhinji vagadziri vanovavarira kutenderera kwepamusoro, kuchengetedzwa kubva kune dzakaomarara nharaunda, kuvhunduka uye vibration, uye yakakwirira tembiricha yekushandisa.
RF connectors uye cable magungano anowanzo kuchinjwa. Zvinodiwa zvakajairika zvinosanganisira zvinongedzo zvinobatanidza zviri pamitsetse yepakati kana nenhamba isinganzwisisike yemapini. Vagadziri vanowanzoda yedu yekubatanidza RF yekubatanidza, seMagnumRF ™ kana Bullseye® test point masisitimu, kuti ive nenzvimbo yakatarwa kuverenga, nzvimbo, uye tsika masisitimu. Izvi zvinogona kuvabvumira kudzikisa kureba kwewaya kana kubatanidza chinongedzo munzvimbo shoma paPCB, zvichibvumira chinongedzo kuiswa padyo nechip. Phase-inofananidzwa wiring uye kunyora zvakare zvakajairika RF shanduko.
Yese yemienzaniso yadudzwa pamusoro igadziriso kune iripo zvinongedzo. Mamwe masisitimu anoda zvibatanidza zvitsva, izvo zvinogona kusanganisira mapini echinyakare uye zvidhindo zvikamu, epurasitiki insulators uye dzimba, tsika RF, simbi, yakakosha mapakeji, tsika dzekugara uye mapakeji, nezvimwe. Shanda padhuze nemubatsiri wako wekubatanidza kugadzira iyo yakanakira yekubatanidza mhinduro kuti uwedzere kuita kwehurongwa.
