Kulokhu okuthunyelwe kwebhulogi, sizohlola amasu asebenzayo nezinqubo ezingcono kakhulu zokuthuthukisa idizayini yamabhodi esekethe aguquguqukayo ukuze sifinyelele ubuqotho besignali obungenasici.
Isingeniso :
Ubuqotho besignali budlala indima ebalulekile ekusebenzeni ngempumelelo kwemishini kagesi, ikakhulukazi emkhakheni wamabhodi esekethe aqinile aqinile.Lawa mabhodi ahlanganisa izinzuzo zama-substrates aqinile futhi aguquguqukayo, okwenza izinselele zokuklama eziyingqayizivele.Ukuqinisekisa ukudluliswa kwesiginali okuphelele kanye nokunciphisa izinkinga ezingaba khona njengokuphazanyiswa kukagesi kagesi (EMI) kanye ne-crosstalk, isu lokuklama elilungiselelwe kahle libalulekile.
Ukuqonda Ubuqotho Besiginali :
Ubuqotho besignali bubhekisela ekuthembekeni kwezimpawu zikagesi njengoba zisakazeka ngesekhethi.Ukuze kudluliswe okuthembekile, okungenaphutha kwedatha yedijithali noma ye-analog, ukugcinwa kobuqotho besignali kubalulekile.Emabhodini esekethe aqinile-aguquguqukayo, inhlanganisela yezinto eziqinile nezivumelana nezimo kwandisa ubunkimbinkimbi bezinkinga zesignali yobuqotho.
Ukuze kuthuthukiswe ubuqotho besignali, abaklami kufanele bacabangele izici ezibalulekile ezilandelayo:
1. Ukulawulwa kwe-impedance: Ngokufanisa ukuvinjelwa kokulandela umkhondo kanye nemigqa yokudlulisela ekuvinjweni kwezingxenye ezixhuma kuzo, ukubonakaliswa kwesignali nokuhlanekezela kungancishiswa.Amasu afana nomzila olawulwayo we-impedance kanye nokusetshenziswa kwezibali ze-impedance angasiza ekufinyeleleni ubuqotho besignali obufanele.
2. Ukunciphisa i-Crosstalk: I-Crosstalk yenzeka lapho inkambu kazibuthe ye-trace eyodwa iphazamisa ukulandelana okuseduze, okubangela ukulimala kwesignali.Isikhala esicophelelayo, ukuvikela, kanye namasu afanele omzila angasetshenziswa ukunciphisa i-crosstalk nokuqinisekisa ubuqotho besignali.
3. Ukuvikela i-EMI: Amabhodi esekethe e-Rigid-flex asengozini yokuphazanyiswa yi-electromagnetic (EMI) ngenxa yezingxenye zawo eziguquguqukayo.Ukubeka phansi ngendlela efanele, ukuvikela, nokubeka ingxenye ngokucophelela kusiza ukuvimbela amasignali angafuneki futhi kuthuthukise ikhwalithi yesignali.
Ukuthuthukisa idizayini yebhodi lesifunda eliqinile ukuze uthole ubuqotho besignali :
1. Ukupakishwa kwesendlalelo: Ukukhethwa nokuhlelwa kwezendlalelo ebhodini lesifunda le-rigid-flex kuthinta kakhulu ubuqotho besignali.Amandla abekwe ngokuhlelekile nezindiza eziphansi zisiza ukunciphisa umsindo futhi zithuthukise ukusebenza kwesignali.Ukuhlukanisa ibhodi ezindaweni ezihlukene ze-analog, idijithali, kanye nezingxenye zefrikhwensi ephezulu nakho kusiza ukunciphisa ukuxoxisana.
2. I-Traceroute: Amasu omzila asebenzayo adlala indima ebalulekile ekugcineni ubuqotho besignali.Izinqubo ezibalulekile zihlanganisa ukugwema ama-engeli abukhali, ukunciphisa ubude bokulandelela, ukusebenzisa umzila wokubhanqa ohlukile wamasignali anesivinini esikhulu, nokugcina ukulandelelwa kwefrikhwensi ephezulu kufushane futhi kuqondile.
3. Izindawo zokugoba nezokugoba: Ukuklama izindawo zokugoba nge-bend radii efanelekile kubalulekile ekuvimbeleni izinkinga zesignali yobuqotho.Ukugoba okweqile noma ukugoba okucijile kungabangela ukungafani kwe-impedance, ukulahlekelwa kwesignali nokwehluleka ngaphambi kwesikhathi.Ukulandela imihlahlandlela yokuklama yendawo eguquguqukayo yomkhiqizi kuqinisekisa ukwethembeka okudingekayo kanye nobuqotho besignali.
4. Ukubeka phansi kanye Nokuvikela: Izindlela ezinhle zokubeka phansi zibalulekile ekugcineni ubuqotho besignali.Indiza yaphansi ene-impedance ephansi inikeza iphuzu elithembekile lereferensi lamasignali, ukunciphisa umsindo nokuthuthukisa ikhwalithi yesignali.Ukuvikela imikhondo ebucayi, njengemigqa yedatha yesivinini esikhulu, enezindiza eziphansi noma izihluthulelo zesignali kungasiza ekunciphiseni ubungozi be-EMI.
5. Ukuphathwa Kokushisa: Ukuphathwa okushisayo okufanelekile kubalulekile kumabhodi esekethe aqinile-flex.Ukushisa okudlulele kungaba nomthelela omubi ubuqotho besignali kanye nokwethembeka okuphelele kwebhodi.Ukusebenzisa osinki okushisa, izimbobo zokupholisa, kanye nokuthuthukisa ukubekwa kwengxenye ukuze kuthuthukiswe ukugeleza komoya okusebenzayo kungasiza ukugwema amazinga okushisa angaphezu kwamandla.
6. Ukulingisa ubuqotho besignali nokuhlaziya: Besebenzisa amathuluzi okulingisa athuthukile, abaklami bangakwazi ukuhlonza futhi balungise izinkinga zesiginali yobuqotho ekuqaleni kwenqubo yokuklama.Amathuluzi afana nezixazululi zensimu ka-electromagnetic, izifanisi zolayini wokudlulisa, nabahlaziyi bobuqotho besignali angasiza ukukhomba izinkinga ezingaba khona futhi akhiqize izixazululo ezithuthukisiwe.
Isiphetho :
Ukuthola ubuqotho besignali obuhle kakhulu ekwakhiweni kwamabhodi esekethe aqinile-flex kudinga indlela yokwenza kahle ecabangela ukulawulwa kwe-impedance, crosstalk, EMI shieding, nezinye izici ezihlukahlukene zokuklama.Ngokusebenzisa ngokucophelela amasu angenhla nokugxila ezenzweni ezingcono kakhulu, abaklami bangaqinisekisa ukudluliswa kwesignali okuthembekile, banciphise umsindo, futhi bathuthukise ukusebenza.Ukuhlala unolwazi ngentuthuko yakamuva kumathuluzi okulingisa ubuqotho besignali namathrendi embonini nakho kubalulekile ekuthuthukisweni okuqhubekayo emkhakheni.Ukwenza kahle ubuqotho besignali kumabhodi esekethe aguquguqukayo ngokungangabazeki kuzovumela ukuhlanganiswa okungenamthungo ezinhlelweni ezihlukahlukene ze-elekthronikhi.
