Izixhumi eziqhelekileyo ziqhelekileyo kwiinkqubo eziphezulu zokusebenza
Abaqulunqi bahlala bezama ukusebenzisa unxibelelwano oluqhelekileyo kwiimveliso zabo zokugqibela. Uninzi lwabantu lucaphula ukusebenziseka ukucacisa ukuba kutheni benamathela kwiimveliso eziqhelekileyo ngaphandle kweshelufu. Ngamanye amaxesha, nangona kunjalo, akukho mveliso isemgangathweni ekhoyo ehlangabezana neemfuno zoyilo lwesistim kwaye unxibelelwano oluqhelekileyo okanye olulungisiweyo luyakhethwa.
Ukusetyenziswa kweziqhagamshelo ezingekho mgangathweni kuxhaphake kakhulu kunokuba uninzi lwabayili becinga. Umzekelo, malunga ne-25% yeentengiso ze-Samtec aziyimveliso engaqhelekanga, ukusuka kuhlengahlengiso oluncinci lweemveliso ezikhoyo ukuya kwiinkqubo ezintsha zokudibanisa. Ezi mveliso ziquka i-high-speed board-to-board (sandwich) iinkqubo, iindibano zentambo ze-high-speed, iipaneli ze-backplane kunye neenkqubo zentambo, iipini ezimbini kunye neenkqubo zesokhethi, iindibano zekhebula ezisebenzayo (ezibizwa ngokuba yi-"mid-board optical transceivers" kwisikhokelo esitsha sokukhanya sikaSamtec), kunye nezihlanganisi zeRF kunye neendibano zentambo.
Abaqulunqi beenkqubo zesantya esiphezulu (i-112 Gb / s ireyithi yedatha nge-channel PAM4, i-224 ezayo) njengamaziko edatha, ii-supercomputers, izixhobo zokuvavanya ezizenzekelayo, kunye nokucinga kwezonyango zihlala zisebenzisa iindibano zentambo zesantya esiphezulu ukudlulisa inani elikhulu ledatha kwidatha ephezulu. amaxabiso.
Nangona kukho iintlobo ngeentlobo zeendibano zentambo ezinesantya esiphezulu, abathengi abaninzi bachaza uhlengahlengiso kwezi mveliso zisemgangathweni. Uhlengahlengiso oluqhelekileyo lubandakanya uyilo lwe-PCB yesiko lokwenziwa kwemephu ye-pin yezicelo ezithile, ukubeka amatyholo okhuselo malunga neentambo eziphambukayo ezisezantsi, okanye ukongeza iileyibhile kwizihlanganisi kunye neentambo ukuchonga amanani ayinxalenye okanye ukunika imiyalelo, ukubala nje ambalwa kumakhulu anokubakho. iinguqulelo ezinokuthi zenziwe.
Olunye uhlengahlengiso oludumileyo kukudibanisa kunye nokudibanisa isiphelo se-1 kunye nokuphela kwezixhumi ezi-2 zecandelo. Ngokomzekelo, i-Flyover® QSFP-DD ikhonkco yepaneli yangaphambili inokupheliswa kuyo nayiphi na inamba ye-high-density end-2 connectors ebekwe kufuphi ne-chip. Abaqulunqi badinga iindidi ezahlukeneyo zokuqhagamshelana kwiinkqubo zonxibelelwano lwangaphambili, oluphakathi, nasemva.
Iinkqubo zokusika ezikhawulezayo zifuna isizukulwana esilandelayo seziqhagamshelo eziphezulu zokusebenza. Nangona kunjalo, abavelisi abaninzi bayila izicelo "ezithe ngqo" ezifana ne-automation ye-industrial, irobhothi, iimveliso ezifakwe ngaphakathi, kunye nombono kunye neenkqubo zokhuseleko. Ezi bhokisi zihlala zisebenzisa uqhagamshelo lwesiqhelo olusisiseko, njengeetheminali zeposi ezisikwere (" izihlanganisi ") kunye neebhodi zesokethi. Uyilo olulula lwezi mveliso - umgca we-strip insulators zeplastiki kunye ne-centerlines engekho encinci (umzekelo, i-2.54 okanye i-2.00mm kunye ne-1.00 okanye i-0.80mm pitch) - yenza ukuguqulwa kube lula kwaye ngokukhawuleza, kwaye ngoko kungabizi.
Ukuguqulwa okudumileyo kubandakanya i-polarization ye-multi-pin - ukususa izikhonkwane - ukuvumela i-keying, i-airflow, imephu yesignali, kunye nesithuba esongezelelweyo sokuhanjiswa kwamandla okanye umgama we-creepage kunye nokucoca ukuhlangabezana nemigangatho yokhuseleko kunye nokulawula. Uninzi lwabayili abasebenzisa izihlanganisi zenqanaba lebhodi bazama ukuhlangabezana ne-UL kunye ne-CE 61800-5-1 , echaza umgama we-creepage kunye nomgama wokucoca kwibakala lezinto eziphathekayo, i-voltage yokusebenza, kunye nenqanaba lokungcola.
Olunye uhlengahlengiso oludumileyo kukongezwa kokulungelelaniswa kunye neempawu zepolarization ezifana nekhaka, ukungenisa, kunye nenkxaso yeplagi eyimfama, kunye nokudityaniswa kwamandla kunye nezikhonkwane zesignali kwikhonkco elilodwa. Ukudibanisa amandla kunye nezikhonkwane zomqondiso kwinkqubo yokudibanisa enye igcina indawo ye-PCB kwaye iphucula ukunyamezela kumaqela adibanisayo.
Uninzi lweziqhagamshelo zebhodi ukuya kwibhodi zinophawu oluyilwe ngononophelo lwe-signal-to-ground configuration ukuphumeza i-SI (ingqibelelo yesiginali) ukusebenza, efuna ukuguqulwa kwemowudi ephantsi ukunciphisa ingxolo ye-radiated okanye uvakalelo kwingxolo. Ukuba intsebenzo eyongezelelweyo yokukhusela iyadingeka, isidibanisi sinokufakwa kwisikhuselo sesinyithi sangaphandle esijikeleza yonke inkqubo yokudibanisa ukukhwelana ukunciphisa i-EMI kunye nemiphumo ye-EMC.
I-Electroplating yolunye uhlengahlengiso oluqhelekileyo; Oku kubandakanya igolide enzima, isilivere kunye ne-palladium nickel, phakathi kwezinye. Uninzi lwabaqulunqi bajonge imijikelo ephezulu, ukhuseleko kwindawo erhabaxa, ukothuka kunye nokungcangcazela, kunye namaqondo obushushu aphezulu okusebenza.
Izixhumi ze-RF kunye neendibano zentambo zihlala zilungiswa. Iimfuno eziqhelekileyo ziquka iziqhagamshelo zoqhagamshelwano ezibekwe kumbindi ongqongqo okanye ezinenani elingaqhelekanga lezikhonkwane. Abaqulunqi bahlala befuna uqhagamshelo lwethu lweRF, njengeMagnumRF™ okanye iisistim zovavanyo ze-Bullseye®, ukuba zibe neendawo ezithile zokubala, izithuba, kunye noyilo oluqhelekileyo. Oku kunokubavumela ukuba banciphise ubude bocingo okanye bafake isidibanisi kwindawo elinganiselweyo kwi-PCB, ukuvumela isidibaniso ukuba sibekwe kufutshane netshiphu. Iingcingo ezihambelana nenqanaba kunye nokuleyibheli nazo zikwaluhlengahlengiso oluqhelekileyo lweRF.
Yonke le mizekelo ikhankanyiweyo apha ngasentla luhlengahlengiso kwizihlanganisi ezikhoyo. Ezinye iisistim zifuna izihlanganisi ezitsha ngokupheleleyo, ezinokubandakanya izikhonkwane zesiko kunye neenxalenye zesitampu, izigqubuthelo zeplastiki kunye nezindlu, iRF yesiko, isinyithi, iipakethi ezikhethekileyo, izindlu zesiko kunye neepakethe, kunye nokunye. Sebenza ngokusondeleyo nomboneleli wakho wokudibanisa ukwenza isisombululo esifanelekileyo sokunxibelelana ukwandisa ukusebenza kwenkqubo.
