UHLELO LWESICWANGCISO
ISAZISO ESIBALULEKILE IBHODI LOKUBONISA
I-Linear Technology Corporation (LT C ) ihlinzeka nge(i)mikhiqizo evaliwe ngaphansi kwezimo ezilandelayo ze-AS IS:
Le khithi yebhodi lokubonisa (i-DEMO BOARD) ethengiswayo noma ehlinzekwa yi-Linear Technology ihloselwe ukusetshenziselwa UKUTHUTHUKISWA KOBUNJININZI NOMA IZINHLOSO ZOKUHLOLA KUPHELA futhi ayinikeziwe i-LT C ukuze isetshenziselwe ukuthengisa. Kanjalo, IBHHODI LE-DEMO lapha lingase lingapheleli ngokuya ngedizayini edingekayo-, ukumaketha-, kanye/noma ukucatshangelwa kokuvikela okuhlobene nokukhiqiza, okuhlanganisa kodwa kungagcini nje ngezinyathelo zokuphepha komkhiqizo ngokuvamile ezitholakala ezimpahleni zokuthengisa eziphelile. Njengesibonelo, lo mkhiqizo awuweli ngaphansi komyalelo we-European Union mayelana nokuhambisana kwe-electromagnetic ngakho-ke ungase uhlangabezane nezimfuneko zobuchwepheshe zomyalelo, noma ezinye iziqondiso. Uma le khithi yokuhlola ingahlangabezani nezicaciso ezishiwo kumanuwali WE-DEMO BOARD ikhithi ingase ibuyiswe zingakapheli izinsuku ezingu-30 kusukela ngedethi yokulethwa ukuze uthole imbuyiselo ephelele. ISIQINISEKISO ESIPHAMBILI ESIYISIQINISEKISO ESIPHELELE EYENZIWA UMdayisi KUBATHENGI FUTHI SISE KHUDLENI LAZO ZONKE IZIQINISEKISO, EZISHIYELWE, EZISHIWO, EZISHIWO, NOMA EZISEMTHETHWENI, KUHLANGANISA NESIPHI ISIQINISEKISO SOKUTHENGISWA NOMA UKULUNGELA KWANOMA YILUPHI IQHAZA. NGAPHANDLE NGEQINISO LALESI SIBUYEKEZO, AYIKHO INHLANGANO EZINGABOPHEZELA OKUNYE NGANOMA YIMUPHI UMONAKALO OYI-NGCONO, OKHETHEKILE, OWEZENZAKALO, NOMA OBAKHONA OKULANDELAYO.
Umsebenzisi uthatha wonke umthwalo nesibopho sokuphatha impahla ngendlela efanele nephephile. Ngaphezu kwalokho, umsebenzisi ukhulula i-LT C kuzo zonke izimangalo ezivela ekuphathweni noma ekusetshenzisweni kwezimpahla. Ngenxa yokwakhiwa okuvulekile komkhiqizo, kuyisibopho somsebenzisi ukuthatha noma yiziphi izinyathelo ezifanele mayelana nokukhishwa kwe-electrostatic. Futhi qaphela ukuthi imikhiqizo elapha kungenzeka ingathobeli imithetho noma i-ejensi eqinisekisiwe (i-FCC, UL, CE, njll.).
Ayikho Ilayisensi enikezwa ngaphansi kwanoma yiliphi ilungelo lobunikazi noma enye impahla yengqondo. I-LT C ayinaso isikweletu sosizo lwezinhlelo zokusebenza, ukwakheka komkhiqizo wekhasimende, ukusebenza kwesofthiwe, noma ukwephulwa kwamalungelo obunikazi nanoma imaphi amanye amalungelo empahla yobuhlakani anoma yiluphi uhlobo. I-LT C okwamanje ihlinzeka ngamakhasimende ahlukahlukene ngemikhiqizo emhlabeni jikelele, ngakho-ke lokhu kuthenga akukhethekile.
Sicela ufunde imanuwali ye-DEMO BOARD ngaphambi kokuphatha umkhiqizo. Abantu abaphethe lo mkhiqizo kumele babe nokuqeqeshwa kwe-elekthronikhi futhi bagcine izindinganiso ezinhle zokuzijwayeza zaselabhorethri. Ukuhluzeka kwengqondo kuyakhuthazwa.
Lesi saziso siqukethe ulwazi olubalulekile lokuphepha mayelana nezinga lokushisa kanye nevolumutages. Ukuze uthole okwengeziwe ngokuphepha, sicela uxhumane nonjiniyela wohlelo lwe-LT C.
