Ngati interlayer capacitance si yaikulu mokwanira, magetsi adzagawidwa kudera lalikulu kwambiri la bolodi, kotero kuti interlayer impedance imachepetsedwa ndipo mphamvu yobwerera ikhoza kubwereranso pamwamba.Pankhaniyi, munda wopangidwa ndi chizindikirochi ukhoza kusokoneza gawo la chizindikiro chapafupi chosintha.Izi si zimene tinali kuyembekezera.Tsoka ilo, pa bolodi la 4-wosanjikiza mainchesi 0.062, zigawozo ndizotalikirana ndipo mphamvu ya interlayer ndi yaying'ono.
Pamene mawaya asintha kuchokera ku gawo 1 kupita ku Layer 4 kapena mosemphanitsa, ndiye kuti izi zidzatsogolera vutoli ngati chithunzi.

Chithunzichi chikuwonetsa kuti pamene chizindikirocho chikuyenda kuchokera ku 1 mpaka 4 (mzere wofiira), kubwereranso kumayenera kusintha ndege (mzere wabuluu).Ngati mafupipafupi a chizindikirocho ndi okwera kwambiri ndipo ndege zili pafupi, kubwereza kwapano kumatha kudutsa mu interlayer capacitance yomwe ilipo pakati pa nthaka ndi mphamvu.Komabe, chifukwa chosowa kulumikizana kwachindunji kwanthawi yobwerera, njira yobwerera imasokonekera, ndipo titha kuganiza za kusokoneza uku ngati kusokoneza pakati pa ndege zomwe zikuwonetsedwa pansipa.

Ngati interlayer capacitance si yaikulu mokwanira, magetsi adzagawidwa kudera lalikulu kwambiri la bolodi, kotero kuti interlayer impedance imachepetsedwa ndipo mphamvu yobwerera ikhoza kubwereranso pamwamba.Pankhaniyi, munda wopangidwa ndi chizindikirochi ukhoza kusokoneza gawo la chizindikiro chapafupi chosintha.Izi si zimene tinali kuyembekezera.Tsoka ilo, pa bolodi la 4-wosanjikiza mainchesi 0.062, zigawozo ndizotalikirana (osachepera 0.020 mainchesi), ndipo mphamvu ya interlayer ndi yaying'ono.Chotsatira chake, kusokonezeka kwa magetsi komwe kufotokozedwa pamwambapa kumachitika.Izi sizingadzetse zovuta za kukhulupirika, koma zidzapanga EMI yochulukirapo.Ichi ndichifukwa chake, tikamagwiritsa ntchito cascade, timapewa kusintha magawo, makamaka ma siginecha apamwamba kwambiri monga mawotchi.
Ndichizoloŵezi chodziwika kuti kuwonjezera capacitor yodulira pafupi ndi dzenje la kusintha kuti muchepetse kutsekeka komwe kumabwera chifukwa chakubwerera komwe kukuwonetsedwa pansipa.Komabe, decoupling capacitor iyi sigwira ntchito pa ma siginecha a VHF chifukwa chakuchepa kwake kodziwikiratu.Kwa ma siginecha a AC okhala ndi ma frequency apamwamba kuposa 200-300 MHz, sitingadalire ma decoupling capacitors kuti apange njira yobwerera yotsika.Chifukwa chake, timafunikira cholumikizira cholumikizira (chapansi pa 200-300 MHz) ndi cholumikizira chachikulu cholumikizira ma frequency apamwamba.

Vutoli litha kupewedwa mwa kusasintha wosanjikiza wa chizindikiro chofunikira.Komabe, mphamvu yaing'ono ya interboard ya bolodi yamagulu anayi imatsogolera ku vuto lina lalikulu: kufalitsa mphamvu.Mawotchi a digito amafunikira mafunde akulu osakhalitsa.Pamene nthawi yokwera / kugwa kwa IC imachepetsa, tifunika kupereka mphamvu pamlingo wapamwamba.Kuti tipereke gwero lachaji, nthawi zambiri timayika ma decoupling capacitor pafupi kwambiri ndi logic iliyonse IC.Komabe, pali vuto: tikadutsa ma frequency odziyimira pawokha, ma decoupling capacitor sangathe kusunga bwino ndikusamutsa mphamvu, chifukwa pama frequency awa capacitor azichita ngati inductor.
Popeza ma ics ambiri masiku ano ali ndi nthawi yofulumira / kugwa (pafupifupi 500 ps), timafunikira chowonjezera chowonjezera chokhala ndi ma frequency apamwamba odzipangira okha kuposa a decoupling capacitor.The interlayer capacitance wa bolodi dera akhoza kukhala ogwira decoupling dongosolo, malinga ngati zigawo ali pafupi kwambiri kuti apereke capacitance okwanira.Choncho, kuwonjezera pa ma decoupling capacitors omwe amagwiritsidwa ntchito kawirikawiri, timakonda kugwiritsa ntchito zigawo zamphamvu zoyandikana kwambiri ndi zigawo zapansi kuti tipereke mphamvu zosakhalitsa ku digito ics.
Chonde dziwani kuti chifukwa cha njira yopangira ma boardboard wamba, nthawi zambiri sitikhala ndi zotchingira zoonda pakati pa zigawo zachiwiri ndi zachitatu za bolodi la magawo anayi.Bolodi la magawo anayi okhala ndi zotchingira zowonda pakati pa zigawo zachiwiri ndi zachitatu zitha kuwononga ndalama zambiri kuposa bolodi wamba wamagulu anayi.
