Dielectric abu
Dielectric abu abu ne tare da rashin aiki mara kyau, wanda aka yi amfani dashi azaman insulating Layer a cikin tsarin PCB. Wasu daga cikin dielectric mica ne, wasu kuma daga cikin dielectric mica, karfe oxide, da filastik. Ƙananan asarar dielectric (ƙarfin da aka rasa a cikin nau’i na zafi), mafi tasiri kayan aikin dielectric shine. Idan wutar lantarki a cikin dielectric abu ya zama mai girma, wato, lokacin da filin lantarki ya zama mai karfi, kayan aiki ba zato ba tsammani ya fara gudanar da halin yanzu. Wannan al’amari shi ake kira dielectric breakdown.

Rtduroid5880 babban mitar laminate daga Rogers
Rogers5880 high mita laminate jerin rungumi dabi’ar PTFE hadaddun ƙarfafa gilashin fiber. Waɗannan microfibers an daidaita su ta ƙididdiga don haɓaka fa’idodin riban fiber kuma suna ba da jagora mafi mahimmanci ga masana’antun da’ira da aikace-aikacen amfani na ƙarshe. Matsakaicin dielectric na waɗannan laminates masu girma shine mafi ƙasƙanci na duk samfuran, kuma ƙarancin ƙarancin wutar lantarki ya sa su dace da aikace-aikacen mitoci mai girma / faɗaɗa inda dole ne a rage tarwatsawa da asara. Saboda ƙarancin ƙarancin ruwan sa, rtduroid5880 ya dace sosai don amfani a yanayin zafi mai girma.

Ana iya yanke waɗannan kayan da’irar ci gaba cikin sauƙi, yanke da sarrafa su don samar da duk wani ƙarfi da reagent da aka saba amfani da su a allunan kewayawa ko gefuna da electroplating rami. Suna da ƙarancin asarar wutar lantarki don kowane kayan PTFE da aka ƙarfafa, kuma suna da ƙarancin ƙarancin ɗanɗano kuma suna da isotropic. Suna da halayen lantarki iri ɗaya a cikin mitoci.
