Chii chinonzi Buried Capacitor?

Yakavigwa capacitor process

Iyo inonzi yakavigwa capacitance process, imwe capacitive zvinhu uchishandisa imwe nzira yemaitiro yakamisikidzwa mune yakajairwa PCB board mukati memukati weiyo tekinoroji yekugadzirisa.

Nekuti zvinhu zvacho zvine hupamhi hwepamusoro capacitance density, saka izvo zvinhu zvinogona kuridza simba rekupa system kuti iparadze basa rekusefa, nekudaro ichidzikisa huwandu hweakasiyana capacitor, inogona kuvandudza mashandiro ezvigadzirwa zvemagetsi uye kuderedza saizi yebhodhi redunhu. kuderedza nhamba ye capacitor pane imwe bhodhi), mukukurukurirana, makombiyuta, zvekurapa, mauto ehondo ane tarisiro yakakura yekushandisa.Nekukundikana kwemvumo yehutete "core" yemhangura-yakapfeka zvinhu uye kuderedzwa kwemutengo, ichashandiswa zvakanyanya.

Zvakanakira kushandisa yakavigwa capacitor zvinhu
(1) Bvisa kana kuderedza iyo electromagnetic coupling maitiro.
(2) Bvisa kana kuderedza kuwedzera kwemagetsi kukanganiswa.
(3) Capacitance kana kupa simba pakarepo.
(4) Kuvandudza kuwanda kwebhodhi.

Yakavigwa capacitor zvinhu sumo

Kune akawanda marudzi eakavigwa capacitor kugadzira maitiro, sekudhinda ndege capacitor, plating plane capacitor, asi indasitiri inoda kushandisa yakatetepa "core" copper cladding material, inogona kugadzirwa nePCB process process.Ichi chinyorwa chinoumbwa nezvikamu zviviri zvefoil yemhangura yakanyungudutswa mune dielectric zvinhu, ukobvu hwemhangura foil kumativi ese ari 18μm, 35μm uye 70μm, kazhinji 35μm inoshandiswa, uye yepakati dielectric layer inowanzo 8μm, 12μm, 16μm, 24μm. , kazhinji 8μm uye 12μm inoshandiswa.

Application musimboti

Yakavigwa capacitor zvinhu zvinoshandiswa panzvimbo yeakaparadzaniswa capacitor.

(1) Sarudza zvinhu, verenga capacitance pachikamu chepamusoro chemhangura, uye dhizaini zvinoenderana nezvinodiwa zvedunhu.

(2) The capacitor layer inofanira kuiswa kunze symmetrically, kana pane maviri akavigwa capacitors, zviri nani kugadzira muchikamu chechipiri chekunze;kana pane imwe nhanho yeakavigwa capacitors, zviri nani kugadzira mukati mepakati.

(3) Sezvo bhodhi repakati rakatetepa kwazvo, dhisiki yemukati yekuzviparadzanisa inofanira kunge yakakura sezvinobvira, kazhinji kanenge> 0.17mm, zvichida 0.25mm.

(4) Mushonga wekonduri kumativi ose ari pedyo ne capacitor layer haigoni kuva nenzvimbo huru isina nzvimbo yemhangura.

(5) saizi yePCB mukati me458mm × 609mm (18″ × 24).

(6) capacitance layer, iwo chaiwo maviri akaturikidzana ari padyo neredhiyo layer (kazhinji simba uye pasi layer), saka, kudiwa kwemavara maviri ekupenda faira.
