Kukanganisa kwesimba (PI)

Simba rakawandaonga, rinonzi Pi, ndeyekusimbisa kana iyo voltage uye ikozvino yeSimba sosi uye nzvimbo yekuenda kunosangana nezvinodiwa. Simba rekuvimbika rinoramba riri rimwe rematambudziko makuru mune yakakwirira-kumhanya PCB dhizaini.

Chikamu chekuvimbika kwesimba chinosanganisira chip level, chip pacalking level, redunhu board level uye system level. Pakati pavo, kuvimbika kwesimba padunhu redunhu rinofanira kusangana nezvinodiwa zvitatu zvinotevera:

Simba Kutendeka Dambudziko

Iyo Simba Kugovera Coness Dambudziko rinonyanya kukonzerwa nekugadziriswa kwekusarudzika kwekushongedza Capacitor, iko kupesvedzera kwedunhu rakawanda remagetsi / pasi pevhu, kusanzwisisika kwendege yekuumbwa uye kusava nebasa riripo. Kuburikidza nekuvimbika kwesimba kufungidzira, matambudziko aya akawanikwa, uye ipapo matambudziko ekuvimbika akavimbika akagadziriswa nenzira dzinotevera:

Simba rekuvimbika kuongorora

MuSimba rekuvimbika kuongorora, marudzi makuru ekufungidzira anovhenekera Dc voltage kudonha kuongororwa kunosanganisira kuongororwa kwechiedza uye ndege mienzaniso paPCB uye inogona kushandiswa kuona kuti yakawanda sei voltage icharasika nekuda kwekupokana kwemhangura.

Inoratidza density yazvino uye tembiricha grapurs ye "Hot mavara" mune pi / inopisa co-simulation

Kuongororwa kutsvaira kazhinji kunotyaira shanduko mukukosha, mhando, uye nhamba yemapaya anoshandiswa mune iyo PDN. Naizvozvo, zvakafanira kuti ubatanidze kurudziro yeparamende uye kuramba kweiyo capacititit yekutaura.

Rudzi rwekuongorora ruzha runogona kusiyana. Vanogona kusanganisira ruzha kubva kuIC Simba Pins iyo inopupurira kutenderedza dunhu redunhu uye kunogona kudzorwa nekukasira capacitors. Kuburikidza nekuongorora ruzha, zvinokwanisika kuongorora kuti ruzha rwakabatanidzwa sei kubva pane rimwe gomba kuenda kune rimwe, uye zvinokwanisika kuongorora ruzha rwekuchinja ruzha.
