Kana iyo yekuvhiringidza kukanganisika haina kuwanda, munda wemagetsi uchagoverwa pamusoro penzvimbo yakakura yebhodhi, kuitira kuti mutengesi arege kuderedzwa uye kudzoka kwazvino kunogona kuyerera kusvika kumusoro. Mune ino kesi, munda wakagadzirwa nechiratidzo ichi anogona kukanganisa munda wekushanduka kwechigadziko. Izvi hazvisi izvo zvatakanga tateerera zvachose. Nehurombo, pane 4-layer board of 0.062 inches inches, iyo matura ari kure kure uye iyo Interlayer Capacitance idiki
Kana iyo wiring shanduko kubva kuLayer 1 kusvika kuLayer 4 kana vice verssa, ipapo ichave inotungamira dambudziko iri rakaratidzwa sepamhepo
Iyo dhayiti inoratidza kuti kana chiratidzo chemucherechedzo kubva kuLayer 1 kusvika kuLayer chiteedzana Kana kuwanda kwechiratidzo kwakakwirira zvakakwana uye ndege dziri pedyo pamwe chete, kudzoka kwazvino kunogona kuyerera kuburikidza neyekisheni yekugona kuripo pakati pevhu ravhu uye iro remagetsi. Nekudaro, nekuda kwekushayikwa kwekungoita zvakananga kwekudzoka kwazvino, nzira yekudzoka inokanganiswa, uye tinogona kufunga nezvekuvhiringidzika uku sekusatarisirwa pakati pezvirongwa zvakaratidzwa sepazefa
Kana iyo yekuvhiringidza kukanganisika haina kuwanda, munda wemagetsi uchagoverwa pamusoro penzvimbo yakakura yebhodhi, kuitira kuti mutengesi arege kuderedzwa uye kudzoka kwazvino kunogona kuyerera kusvika kumusoro. Mune ino kesi, munda wakagadzirwa nechiratidzo ichi anogona kukanganisa munda wekushanduka kwechigadziko. Izvi hazvisi izvo zvatakanga tateerera zvachose. Nehurombo, pane 4-layer bhodhi ye 0.062 inches inches, zviyero zvakaringana (kanokwana kusvika 0,020 inches), uye iyo inches inches idiki. Nekuda kweizvozvo, iyo magetsi emunda kupindira kwakataurwa pamusoro apa kunoitika. Izvi zvinogona kunge zvisingakonzere nyaya dzekuvimbika dzekuvimbika, asi ichasika mamwe EMI. Ndokusaka, patinoita cascade, tinodzivisa kushandura matombo, kunyanya kwenguva refu masaini senge wachi.
Iyo yakajairika tsika yekuwedzera iyo decopling capacitor padhuze neshanduko inopfuura gomba kuti uderedze kusarongeka kwakaitwa nekudzoka kwazvinoratidzwa sepakutanga mufananidzo. Nekudaro, iyi yekuzvishongedza capacitor haina basa reVHF Signals nekuda kweiyo yakaderera yekuzviisa pasi. Zvemasaini eAC NEMAHARA DZINOGONESA ZVAKAWANDA 20000 Naizvozvo, isu tinoda iyo decoupling capacitor (yezasi 200-300 MHz) uye yakakura interboard capacititor yekwana yepamusoro.
Dambudziko iri rinogona kudzivirirwa nekusachinja chikamu chechiratidzo chikuru. Nekudaro, iyo diki interboard yekugona kweiyo ina-layer bhodhi inotungamira kune imwe dambudziko rakakura: kutapurirana kwemagetsi. Clock digital zvinyorwa zvinowanzoda mafuro makuru masimba masimba ekupa mafungu. Sezvo kusimuka / nguva yekudonha kweIC yakaderera, tinoda kuendesa simba pachiyero chepamusoro. Kupa mari yekubhadhara, isu tinowanzoisa decoupling capacitors padyo padhuze nepfungwa dzega. Nekudaro, pane dambudziko: Patinoenda kupfuura iyo yekuzvisarudzira nguva, decoupling carepitors haigone kuchengeta zvinobudirira uye kuendesa simba, nekuti pane aya maClucitor ichaita seInductor.
Sezvo vazhinji vechidiki nhasi vane nekukurumidza / nguva yekudonha Iyo Interlayer Kugona kwedunhu redunhu kunogona kuve chinhu chinoshanda chinoshanda, chero zvimedu zviri pedyo zvakaringana kune mumwe nemumwe kuti vape kukwana kwakakwana. Naizvozvo, kunze kweiye anowanzo shandiswa kusarudza gadziriro, isu tinoda kushandisa zvisina mwero masaga ezvipenga uye nzvimbo dzinovhuvhuta kuti dzipe simba remagetsi kuDhijitari.
Ndokumbira utarise kuti nekuda kweiyo yakajairika redunhu board yekugadzira, isu hatiwanzove neinonetesa vatete pakati pechipiri neyechitatu mataira ebhodhi ina. Bhodhi ina-layer ine vatete vane vaongorori pakati pechipiri uye yechitatu mataira vanogona kubhadhara zvakanyanya kupfuura zvechinzvimbo chemugungano mana-layer bhodhi.
