Ukugqwesa uMqondiso weMfezeko: uPhuculo loYilo lweeBhodi zeSekethe eziguquguqukayo

Kule post yebhlog, siza kuphonononga iindlela ezisebenzayo kunye nezona ndlela zilungileyo zokuphucula uyilo lweebhodi zesekethe eziguquguqukayo ukuphumeza imfezeko yomqondiso ongenakufezekiswa.

Intshayelelo :

Ingqibelelo yomqondiso idlala indima ebalulekileyo ekusebenzeni ngempumelelo kwezixhobo zombane, ngokukodwa kwibala leebhodi zesekethe ezilukhuni ezilukhuni.Ezi bhodi zidibanisa iingenelo ze-substrates eziqinileyo kunye neziguquguqukayo, ukudala imingeni ekhethekileyo yoyilo.Ukuqinisekisa ukuhanjiswa komqondiso ofanelekileyo kunye nokunciphisa imiba enokubakho efana nokuphazamiseka kwe-electromagnetic (EMI) kunye ne-crosstalk, isicwangciso soyilo esilungiselelwe kakuhle sibalulekile.

Ukuqonda uMqondiso weMfezeko :

Ingqibelelo yomqondiso ibhekisela kukunyaniseka kweempawu zombane njengoko zisasazeka kwisekethe.Kuthumelo oluthembekileyo, olungenazimpazamo lwedatha yedijithali okanye ye-analog, ukugcina imfezeko yesiginali kubalulekile.Kwiibhodi zesekethe eziqinileyo, ukudibanisa izinto eziqinileyo kunye neziguquguqukayo kwandisa ubunzima bemiba yengqibelelo yomqondiso.

Ukwandisa imfezeko yomqondiso, abaqulunqi kufuneka baqwalasele ezi zinto zilandelayo zibalulekileyo:

1. Ukulawulwa kwe-impedance: Ngokuhambelana nokuphazamiseka kweendlela zokulandelela kunye nemigca yokuhambisa kwi-impedance yamacandelo adibanisa nawo, ukubonakalisa umqondiso kunye nokuphazamiseka kunokuncitshiswa.Ubuchwephesha obunjengokulawulwa kwendlela yokuthintela kunye nokusetyenziswa kweekhatyhuleyitha ze-impedance kunokunceda ukufikelela kwimfezeko yophawu olufanelekileyo.

2. Ukunciphisa i-Crosstalk: I-Crosstalk yenzeke xa i-electromagnetic field ye-trace enye iphazamisa ukulandelwa okukufutshane, kubangela umonakalo wesignali.Izithuba ezinononophelo, ukukhusela, kunye neendlela ezifanelekileyo zokusebenzisa iindlela zingasetyenziselwa ukunciphisa i-crosstalk kunye nokuqinisekisa imfezeko yomqondiso.

3. Ukukhusela i-EMI: Iibhodi zesekethe eziguquguqukayo ziyakwazi ukuphazamiseka kwi-electromagnetic interference (EMI) ngenxa yeendawo zazo eziguquguqukayo.Ukumisa ngokufanelekileyo, ukukhusela, kunye nokubekwa kwecandelo ngononophelo kunceda ukuthintela iimpawu ezingafunekiyo kunye nokuphucula umgangatho womqondiso.

Ukuphucula uyilo lwebhodi yesekethe eqinileyo yophawu lwemfezeko:

1. I-Layer stacking: Ukukhethwa kunye nokucwangciswa kweengqimba kwibhodi yesekethe ye-rigid-flex ichaphazela kakhulu ingqibelelo yesignali.Amandla abekwe ngobuchule kunye neenqwelomoya zomhlaba zinceda ukunciphisa ingxolo kunye nokuphucula ukusebenza komqondiso.Ukwahlulahlula ibhodi kwiindawo ezahlukeneyo ze-analog, idijithali, kunye ne-high-frequency components nako kunceda ukunciphisa intetho enqamlezileyo.

2. I-Traceroute: Iindlela zobuchule ezisebenzayo zidlala indima ephambili ekugcineni intembeko yomqondiso.Izenzo eziphambili zibandakanya ukuphepha ii-engile ezibukhali, ukunciphisa ubude bomkhondo, ukusebenzisa iindlela ezimbini ezihlukeneyo kwiimpawu zesantya esiphezulu, kunye nokugcina i-high-frequency tracks imfutshane kwaye ithe tye.

3. Iindawo zokugoba kunye neeNdawo zokugoba: Ukuyila iindawo zokugoba kunye ne-bend radii efanelekileyo ibalulekile ekuthinteleni imiba yengqibelelo yomqondiso.Ukugoba okugqithisileyo okanye ukugoba okubukhali kunokubangela ukungalingani kwe-impedance, ukulahleka komqondiso kunye nokungaphumeleli kwangaphambi kwexesha.Ukulandela izikhokelo zoyilo lwendawo yomenzi kuqinisekisa ukuthembeka okufunekayo kunye nokuthembeka komqondiso.

4. I-Grounding and Shielding: Iindlela ezifanelekileyo zokumisa zibalulekile ekugcineni ukunyaniseka komqondiso.Inqwelomoya ephantsi kwe-impedance ephantsi inika indawo ethembekileyo yokubhekisela kwiimpawu, ukunciphisa ingxolo kunye nokuphucula umgangatho wesignali.Ukukhusela umkhondo obuthathaka, njengemigca yedatha yesantya esiphezulu, kunye neenqwelo-moya zomhlaba okanye i-signal strippers inokunceda ukunciphisa ingozi ye-EMI.

5. Ulawulo lwe-Thermal: Ulawulo olufanelekileyo lwe-thermal lubalulekile kwiibhodi zesekethe eziqinileyo.Ukushisa okugqithisileyo kunokuchaphazela kakubi ingqibelelo yesignali kunye nokuthembeka okupheleleyo kwebhodi.Ukusetyenziswa kweesinki zobushushu, iiventi zokupholisa, kunye nokwandisa indawo yokubekwa kwecandelo ukukhuthaza ukuhamba komoya okusebenzayo kunokunceda ukuthintela amaqondo obushushu agqithisileyo.

6. Ukulinganisa ingqibelelo yomqondiso kunye nokuhlalutya: Ukusebenzisa izixhobo zokulinganisa eziphambili, abaqulunqi banokuchonga kwaye balungise imiba yengqibelelo yomqondiso ekuqaleni kwenkqubo yoyilo.Izixhobo ezifana nezisombululi zentsimi ye-electromagnetic, ii-simulators zemigca yothumelo, kunye nabahlalutyi bemfezeko yomqondiso kunokunceda ukukhomba iingxaki ezinokuthi zivelise izisombululo eziphuculweyo.

Isiphelo :

Ukufezekisa imfezeko yomqondiso obalaseleyo kuyilo lweebhodi zesekethe eziguquguqukayo kufuna indlela yokuphucula ethathela ingqalelo ulawulo lwe-impedance, crosstalk, EMI shielding, kunye nezinye izinto ezahlukeneyo zoyilo.Ngokuphumeza ngononophelo ezi ndlela zingasentla kunye nokugxila kwezona ndlela zilungileyo, abaqulunqi banokuqinisekisa ukuhanjiswa komqondiso okuthembekileyo, ukunciphisa ingxolo, kunye nokuphucula ukusebenza.Ukuhlala unolwazi lwenkqubela phambili yamva nje kwizixhobo zokulinganisa imfezeko yesiginali kunye neentsingiselo zeshishini nazo zibalulekile ekuphuculeni okuqhubekayo kwintsimi.Ukuba nobuchule ekufezekiseni imfezeko yomqondiso kwiibhodi zesekethe eziguquguqukayo ngokungathandabuzekiyo kuya kwenza udibaniso olungenamthungo kwizicelo ezahlukeneyo ze-elektroniki.
