Ngaba le mveliso iyayixhasa uyilo olulungiselelwe wena?
Impendulo: Ewe, injalo. Sineqela leengcali ze-R & D elinokwenza uyilo olucwangcisiweyo ngokweemfuno zabathengi ezahlukeneyo. Nokuba ziiparameter zobugcisa ezifana nenani leetshaneli, izinga leesampuli, kunye nesisombululo, okanye iinkalo ezifana nobukhulu bemodyuli kunye nohlobo lwe-interface, zinokulungiswa kwaye zilungiswe ngokweemfuno zakho ezithile. Ngexesha lenkqubo yokwenza ngokwezifiso, iqela lethu le-R & D liza kuqwalasela ngokupheleleyo iimeko zokwenyani zesicelo kunye nezalathisi zobugcisa, zidibene neetekhnoloji eziphambili zemveliso ye-PCB assembly kunye neenkqubo, ukuqinisekisa ukuba sikunika isisombululo se-PCBA sebhodi yentombi ye-AD FMC efanelekileyo kakhulu. Ukususela kwinqanaba loyilo, siza kugcina unxibelelwano olusondeleyo nabathengi kwaye silungise isicwangciso soyilo ngexesha elifanelekileyo ngokwempendulo yabathengi; ngexesha lenqanaba lokuvelisa, siza kusebenzisa iinkqubo zokuvelisa i-PCB assembly ngokuchanekileyo nangokufanelekileyo ukuguqula ngokuchanekileyo uyilo olucwangcisiweyo lube yimveliso yokwenyani, ukuhlangabezana neemfuno ezizodwa zeeprojekthi ezahlukeneyo kunye nabathengi. Kule nkqubo, abasebenzi abaziingcali, ubuchwepheshe obuphambili, kunye neenkqubo ezisebenzayo ziyasebenzisana ukuqinisekisa ukuhanjiswa kweemveliso ezicwangcisiweyo ezikumgangatho ophezulu.
Isicelo: Iingenelo Ezintlanu Ezikhethekileyo zeBhodi yeNtombi ye-AD FMC ye-Multi-channel High-speed AD, Ukudala iModeli yoShishino
Isantya esiphezulu kunye nokuFumana okuchanekileyo: Ukubonelela ngeSiseko esichanekileyo sokuCwangciswa kweDatha
Ngokusebenzisa ii-ADCs ezisebenza kakuhle, imiqondiso emininzi ye-analog inokuqokelelwa ngokulandelelana ngesantya esiphezulu kakhulu sesampulu kunye nesisombululo. Nokuba sisignali etshintsha ngokukhawuleza okanye sisignali esibuthathaka, sinokuguqulwa ngokuchanekileyo sibe sisignali yedijithali, sinike isiseko sedatha esichanekileyo sokucubungula idatha kunye nohlalutyo olulandelayo, kwaye sihlangabezane ngempumelelo neemfuno zokufunyanwa kwedatha ngesantya esiphezulu.
Uzinzo Olugqwesileyo Nokuthembeka: Ukuqinisekisa Ukufunyanwa Kwedatha Okuqhubekayo Nokuzinza
Izinto ze-elektroniki ezikumgangatho ophezulu zikhethwa ngononophelo, njengee-capacitors ze-ceramic ezinee-layer ezininzi ezine-ESR ephantsi ezidityaniswe nee-capacitors ze-tantalum ezinomthamo ophezulu, ukuqinisekisa ukunikezelwa kombane okucocekileyo nokuzinzileyo kunye nokunciphisa ukuphazamiseka kwe-ripple. Ii-inductors ze-ferrite ezifikelela kwi-magnetic kunye nee-inductors ze-wire-precision high-precision zithintela ukuphazamiseka kwe-electromagnetic kwaye zonyusa amandla okulwa nokuphazamiseka kwesekethe. Kwangaxeshanye, ngenkqubo yokuhlolwa komgangatho engqongqo, kubandakanya ukuhlolwa kwe-AOI kunye ne-X-ray ephucukileyo, kunye novavanyo olusebenzayo nolwalupheleyo olulinganisa iimeko zokwenyani zesicelo, i-PCBA inokusebenza ngokuzinzileyo nangokuthembekileyo kwiindawo ezinzima kwaye ngexesha lokusebenza ixesha elide, yandisa kakhulu ixesha lokusebenza elingenaziphene kwenkqubo yokufumana idatha.
Ukulungelelana Okugqwesileyo Kwendalo: Ukujongana Neemeko Zokusebenza Ezinzima Ngokulula
Ubunzima bendawo yokufumana idatha buqwalaselwe ngokupheleleyo kuyilo. Izinto ezikhethiweyo zinokusebenza ngokuqhelekileyo kuluhlu lwamaqondo obushushu ukusuka kwi-40°C ukuya kwi-85°C kunye nendawo yokufuma ehambelanayo ye-5% - 95% (engavuthiyo). Lonke eli modyuli linoyilo olukhethekileyo olungenamswakama, olungenathuli, kunye nonyango olungenantshukumo oluchasene nokungcangcazela, olunokumelana ngempumelelo nempembelelo yothuli, ukufuma, kunye nokungcangcazela kwindawo yemizi-mveliso, kwaye luhlala lubonelela ngokusebenza okuzinzileyo kwenkqubo yokufumana idatha, oluzivumelanisa neemeko ezahlukeneyo zokusebenza ezinzima.
Uyilo olusebenza kakuhle kakhulu nolonga amandla: Ukukhokela uMkhwa omtsha wamandla - ukonga ekuFunyanweni kwedatha
Ii-ADCs ezisebenza kakuhle kunye nezinye izinto zisebenzisa iinkqubo zokuvelisa eziphambili kwaye zineempawu zokusetyenziswa kwamandla aphantsi. Xa zidityaniswe noyilo lwesekethe olufanelekileyo kunye nokukhethwa kwamacandelo, i-PCBA inokulungisa ngobuchule ukusetyenziswa kwamandla kwiindlela ezahlukeneyo zokusebenza. Ngelixa ihlangabezana neemfuno zokufumana idatha ekhawulezayo, inciphisa kakhulu ukusetyenziswa kwayo kwamandla, iphucula ukusebenza kakuhle kokusetyenziswa kwamandla, igcina iindleko zokusebenza zexesha elide kubasebenzisi, kwaye ihambelana nomkhwa wophuhliso lokonga amandla aluhlaza.
