Thermosetting SB578F / AU4V110X jerin gwangworar solenoid mai launi

Ba za a yi watsi da parasitic ba, COLETWE CLIIL, CILDELDIC COIL

1. An gabatar da cewa Parasitic Induction wanda ba za a yi sakaci shine rabin wanda ya kamata a yi la'akari da shi a cikin PCB Via Dandarin.

A cikin shirin nazarin dijital na manyan da'irori, lalacewar lalacewa ta hanyar shigar da vasulance na Vias yawanci ya fi wanda ke haifar da hakan ta hanyar Parasitic Capacitance. Jerin aikinta na parasitic zai raunana gudummawar bayan capacoritor da tace tasirin tsarin samar da wutar lantarki.

2. Zamu iya amfani da tsari mai zuwa don yin lissafin kimanin kwatancen parasitic wanda ke haifar da ta hanyar:

L = 5.08h [4H / D) inda l yake nufin shigarwar ta Via, H shine tsawon ta hanyar Via, kuma d shine diamita na rami. Ana iya ganin shi daga dabara cewa diamita na ta via ba shi da tasiri a cikin shigarwar, amma tsawon ta via rami yana da babban tasiri a kan shigarwar. Har yanzu amfani da misalin da ke sama, ana iya yin lissafin shigarwar rami kamar: l = 5.08 x 0.0100 (4x0.050 / 0.010) = 1.015 NH. If the rise time of the signal is 1nS, the equivalent impedance is XL=TL/T10-90=3.190. Wannan nau'in ba za a iya yin watsi da wannan ba lokacin da akwai babban mita. Yana da mahimmanci musamman a lura cewa kewaye mai ɗaukar hoto yana buƙatar wucewa ta hanyar guda biyu lokacin da haɗa wutar lantarki da kuma m, don haka parasitic sa na wa'azi.

Sanadin yin dumama

Gabatarwa da bayyana dalilin dumama.

1. Waya tayi yawa sosai, wanda zai haifar da juriya na tabbatarwa ya zama babba. A karkashin yanayin cewa ingantacciyar darajar ta yanzu tabbatacce ne, daidai ne ga gacinon da zai yi zafi.

2, shigarwar ta cika, da wannan irin zazzabin ma yana da yaduwa sosai.

3. Akwai babban wutar lantarki mai ƙarfi a duka iyakar haɗarin duka, don haka ainihin an canza su ya zama mafi girma, wanda zai iya rage adadin ya zama tsayi. Matsakaicin juyawa, ƙananan rippple na yanzu, ƙananan asarar magnetic, galibi zafin zafi.
