Kodi Buried Capacitor ndi chiyani?

Njira yoyika capacitor

Otchedwa m'manda capacitance ndondomeko, ndi zina capacitive zakuthupi ntchito njira njira ophatikizidwa wamba PCB bolodi mu wosanjikiza wamkati wa luso processing.

Chifukwa zakuthupi ali mkulu capacitance kachulukidwe, kotero zakuthupi akhoza kuimba dongosolo kotunga mphamvu decouple ntchito zosefera, potero kuchepetsa chiwerengero cha capacitors osiyana, akhoza kusintha ntchito ya mankhwala pakompyuta ndi kuchepetsa kukula kwa bolodi dera ( kuchepetsa chiwerengero cha capacitor pa bolodi limodzi), mu mauthenga, makompyuta, zachipatala, minda ya asilikali ndi yotakata ntchito chiyembekezo.Ndi kulephera kwa chivomerezo cha zinthu zopyapyala za "core" zamkuwa ndi kuchepetsa mtengo, zidzagwiritsidwa ntchito kwambiri.

Ubwino wogwiritsa ntchito zida zokwiriridwa capacitor
(1) Chotsani kapena kuchepetsa mphamvu yamagetsi yolumikizira.
(2) Chotsani kapena kuchepetsa kusokoneza kwina kwamagetsi.
(3) Mphamvu kapena kupereka mphamvu nthawi yomweyo.
(4) Kupititsa patsogolo kachulukidwe ka bolodi.

Chiyambi cha zinthu zokwiriridwa capacitor

Pali mitundu yambiri yopangira capacitor yokwiriridwa, monga kusindikiza capacitor ndege, plating capacitor ndege, koma makampani amakonda kugwiritsa ntchito woonda "pachimake" mkuwa cladding zakuthupi, amene angapangidwe ndi PCB processing ndondomeko.Nkhaniyi imapangidwa ndi zigawo ziwiri za zojambulazo zamkuwa zomwe zimayikidwa muzinthu za dielectric, makulidwe a zojambulazo zamkuwa kumbali zonsezo ndi 18μm, 35μm ndi 70μm, kawirikawiri 35μm amagwiritsidwa ntchito, ndipo gawo lapakati la dielectric nthawi zambiri ndi 8μm, 12μm, 16μm, 24μm. , kawirikawiri 8μm ndi 12μm amagwiritsidwa ntchito.

Mfundo yogwiritsira ntchito

Zinthu zokwiriridwa za capacitor zimagwiritsidwa ntchito m'malo mwa capacitor wolekanitsidwa.

(1) Sankhani zinthu, kuwerengera capacitance pa chigawo cha pamwamba mkuwa, ndi kupanga malinga ndi zofunikira dera.

(2) The capacitor wosanjikiza ayenera anaika symmetrically, ngati pali zigawo ziwiri za capacitors m'manda, ndi bwino kupanga mu wosanjikiza wachiwiri kunja;ngati pali wosanjikiza umodzi wa capacitor m'manda, ndi bwino kupanga pakati.

(3) Popeza bolodi pachimake ndi woonda kwambiri, mkati kudzipatula litayamba ayenera kukhala lalikulu monga n'kotheka, zambiri osachepera> 0.17mm, makamaka 0.25mm.

(4) Chigawo cha conductor kumbali zonse zomwe zili pafupi ndi capacitor sizingakhale ndi malo akuluakulu opanda mkuwa.

(5) PCB kukula mkati 458mm × 609mm (18″ × 24).

(6) capacitance wosanjikiza, zigawo ziwiri zenizeni pafupi ndi dera lozungulira (nthawi zambiri mphamvu ndi nthaka wosanjikiza), choncho, kufunikira kwa fayilo iwiri yojambula kuwala.
