Menene Buried Capacitor?

Tsarin capacitor da aka binne

The abin da ake kira binne capacitance tsari, shi ne wani capacitive abu ta yin amfani da wani tsari tsari saka a cikin talakawa PCB hukumar a ciki Layer na wani aiki fasahar.

Saboda kayan yana da babban ƙarfin ƙarfin ƙarfin, don haka kayan na iya kunna tsarin samar da wutar lantarki don ƙaddamar da aikin tacewa, ta haka ne rage yawan adadin capacitors daban-daban, zai iya inganta aikin samfurori na lantarki da kuma rage girman allon kewayawa ( rage adadin capacitors a kan allo guda), a cikin sadarwa, kwamfutoci, likitanci, filayen soja suna da fa'idar aikace-aikace.Tare da gazawar haƙƙin mallaka na bakin ciki "cibiyar" kayan da aka yi da jan karfe da kuma rage farashin, za a yi amfani da shi sosai.

Amfanin amfani da kayan capacitor da aka binne
(1) Kawar da ko rage tasirin haɗakarwa na lantarki.
(2) Cire ko rage ƙarin tsangwama na lantarki.
(3) Capacitance ko samar da makamashi nan take.
(4) Inganta yawa na hukumar.

Gabatarwar kayan capacitor

Akwai nau'ikan nau'ikan tsarin samar da capacitor da aka binne, kamar bugun jirgin sama capacitor, plating capacitor na jirgin sama, amma masana'antar ta fi karkata don amfani da bakin bakin “core” jan karfe cladding abu, wanda za a iya yi ta hanyar sarrafa PCB.Wannan abu yana kunshe da yadudduka biyu na takarda na jan karfe sandwiched a cikin dielectric abu, kauri na jan karfe tsare a bangarorin biyu ne 18μm, 35μm da 70μm, yawanci 35μm da ake amfani da, da tsakiyar dielectric Layer ne yawanci 8μm, 12μm, 16μm, 24μm , yawanci 8μm da 12μm ana amfani da su.

Ƙa'idar aikace-aikacen

Ana amfani da kayan capacitor da aka binne a maimakon raba capacitor.

(1) Zaɓi kayan, ƙididdige ƙarfin kowane raka'a na saman jan ƙarfe mai rufi, da ƙira bisa ga buƙatun kewayawa.

(2) Ya kamata a shimfiɗa Layer na capacitor a hankali, idan akwai nau'i biyu na capacitors da aka binne, ya fi kyau a tsara shi a cikin Layer na waje na biyu;idan akwai daya Layer na capacitors binne, shi ne mafi alhẽri a zayyana a tsakiya.

(3) Da yake babban allon yana da bakin ciki sosai, ya kamata faifan keɓewar ciki ya zama babba gwargwadon iko, gabaɗaya aƙalla> 0.17mm, zai fi dacewa 0.25mm.

(4) Layin madugu a bangarorin biyu kusa da Layer capacitor ba zai iya samun babban yanki ba tare da yankin jan karfe ba.

(5) Girman PCB tsakanin 458mm × 609mm (18 ″ × 24).

(6) capacitance Layer, ainihin yadudduka biyu kusa da kewaye Layer (gaba ɗaya iko da ƙasa Layer), saboda haka, da bukatar biyu haske fenti fayil.
