Muhupenyu hwezuva nezuva, iyo yakawanda-layer PCB redunhu bhodhi parizvino ndiyo inonyanya kushandiswa redunhu bhodhi mhando. Nechikamu chakakosha chakadaro, chinofanira kubatsirwa kubva kune akawanda mabhenefiti eakawanda-layer PCB redunhu bhodhi. Ngatitarisei zvakanakira.
5. Inogona kuumba dunhu rine imwe impedance, iyo inogona kuumba yakakwirira-speed transmission circuit;
6. Circuit, magnetic circuit shielding layer inogona kuiswa, uye metal core heat dissipation layer inogonawo kuiswa kuti isangane nezvinodiwa zvemabasa anokosha akadai sekudzivirira uye kupisa kupisa.
Nekuenderera mberi kwekuvandudza tekinoroji yemagetsi uye nekuenderera mberi kwekuvandudzwa kwezvinodiwa zvemidziyo yemagetsi mukombuta, kurapwa, ndege uye mamwe maindasitiri, bhodhi redunhu riri kusimukira munzira yekuderera kwevhoriyamu, kuderedza kunaka uye kuwedzera density. Nekuda kwekuganhurirwa kwenzvimbo iripo, mabhodhi akadhindwa ega uye maviri-mativi maviri haakwanise kuwedzera kuwedzera kwehuwandu hwegungano. Nokudaro, zvakakosha kufunga nezvekushandiswa kwemapuranga ematunhu akawanda ane nhamba yakakwirira yezvikamu uye hukuru hwegungano. Multilayer circuit boards yakashandiswa zvakanyanya mukugadzira zvigadzirwa zvemagetsi nekuda kwekugadzirisa kwavo kushanduka, kugadzikana uye kutendeseka kushanda kwemagetsi uye kushanda kwepamusoro kwehupfumi.
