Haske mai ƙarfi (pi)

Ingancin iko, ana kiranta Pi, shine tabbatar ko ƙarfin lantarki da na yanzu tushen tushen wutar lantarki da makomar da ake buƙata. Hakikanin iko ya kasance ɗaya daga cikin manyan ƙalubalen cikin ƙirar PCB mai girma.

Matsayin ikon wutar lantarki ya hada da matakin guntu, matakin cocaging matakin, matakin kwamitin da matakin kwamitin da matakin tsarin. Daga gare su, ikon ƙarfin iko a matakin allo ya kamata ya cika waɗannan guda uku masu zuwa:

1. Yi voltage ripple a cikin guntu pin karami fiye da ƙayyadaddun ƙayyadaddun (alal misali, kuskuren tsakanin ƙarfin lantarki da 1V ƙasa da + /--50mv);

2.

3, reduce electromagnetic interference (EMI) and maintain electromagnetic compatibility (EMC) : power distribution network (PDN) is the largest conductor on the circuit board, so it is also the easiest antenna to transmit and receive noise.

Matsalar amincin iko

Matsalar samar da wutar lantarki ita ce sanadiyyar lalacewa ta hanyar daidaitaccen tsari mai mahimmanci, mummunan yanki na samar da wutar lantarki / ƙasa mai mahimmanci, ƙirar jirgin sama da ba a iya amfani da shi ba. Ta hanyar ingantaccen tsarin mulki, waɗannan matsalolin an samo su, sannan kuma an magance matsalolin da amincin da kuma hanyoyin:

(1) ta hanyar daidaita girman layin PCB da kauri da sinadarin hanyar da aka nuna, daidaita tsarin sararin samaniya, a ƙasa, daidaita abin da ya shafi amfani da shi.

(2) An yi amfani da nazarin binciken wutar lantarki don wadatar wutar lantarki da aka yi amfani da shi akan PCB, kuma an ƙara capacort don sarrafa wutar lantarki a ƙasa bunkasa;

(3) A cikin ɓangaren tare da yawa na high ass, daidaita matsayin na'urar don yin wucewa ta yanzu ta hanyar yadewa.

Binciken Haske

A cikin binciken Hakkin Haske, babban nau'in sayan iko sun haɗa da DC Volonage dutsen nazarin, nazarin bincike da bincike na amo. Binciken DC na DC ya hada da bincike na hadadden wiring da kuma jirgin sama mai zane akan PCB kuma ana iya amfani dashi don tantance wutar lantarki da za a rasa saboda juriya na jan ƙarfe.

Nuna da zane-zanen zazzabi da yawan zafin jiki na "Hotunan zafi" a PI / Hoto na Haske

Binciken bincike yawanci yana tuƙa canje-canje a cikin ƙimar, nau'in, da adadin masu ɗaukar hoto da ake amfani da su a cikin PDn. Saboda haka, ya zama dole a haɗa da ba da labari na parasitic da juriya na samfurin Capacitor.

Nau'in bincike na amo na iya bambanta. Suna iya haɗawa da amo daga fil wutar lantarki wanda ke hana kewaye da jirgi kuma zai iya sarrafa shi ta hanyar masu ɗaukar nauyi. Ta hanyar bincike na amo, yana yiwuwa a bincika yadda ake haɗuwa da amo guda ɗaya daga rami ɗaya zuwa wani, kuma yana yiwuwa a bincika amo na agara.
