Ka whakamahia te nuinga o tenei pepa mo nga PCB multilayered me nga papa taiawhio teitei, e hiahia ana kia iti ake te ahua o te mata o te pepa ki raro iho i tera o te konumohe parahi noa kia noho tonu ai a raatau mahi penei i te peeling resistance i te taumata teitei.No te kāwai motuhake o te konumohe parahi electrolytic ki te mana taratara.Ka whakatauritea ki te pepa parahi electrolytic auau, ko nga tioata o te pepa parahi LP he tino pai nga kakano equiaxed (<2/zm).Kei roto i a raatau nga tioata lamellar hei utu mo nga poupou, engari he hiwi papatahi me te taumata iti o te taratara o te mata.He pai ake o raatau i te pai ake o te rahi me te pakeke ake.
●He tohu iti mo FCCL
●MIT teitei
●He pai te taurite
●He mawhero, he pango ranei te pepa i mahia
●3 paparanga FCCL
●EMI
