Iyo PCB marongerwo ibhodhi redunhu rakadhindwa.Iyo yakadhindwa yedunhu bhodhi inonziwo yakadhindwa redunhu bhodhi, inova mutakuri unobvumira akasiyana emagetsi zvikamu kuti zvibatanidzwe nguva dzose.

PCB dhizaini inoshandurirwa mune yakadhindwa yedunhu bhodhi marongero muChinese.Bhodhi redunhu patsika yechinyakare ndiyo nzira yekushandisa kudhinda kuburitsa dunhu, saka inonzi yakadhindwa kana kudhindwa redunhu bhodhi.Kushandisa mapuranga akadhindwa, vanhu havagoni kungodzivisa zvikanganiso zve wiring mukugadzirisa (kusati kwaonekwa kwePCB, zvikamu zvemagetsi zvose zvakabatanidzwa newaya, izvo zvisiri kungosvibisa chete, asiwo zvine ngozi dzekuchengetedza).Munhu wekutanga kushandisa PCB aive wekuAustria anonzi Paul.Eisler, yakatanga kushandiswa muredhiyo muna 1936. Kushandiswa kwakapararira kwakaonekwa muma1950.

PCB marongerwo maitiro

Parizvino, indasitiri yemagetsi yakakurumidza kukura, uye basa revanhu uye hupenyu hazviparadzaniswe kubva kune akasiyana zvigadzirwa zvemagetsi.Sechinhu chakakosha uye chakakosha mutakuri wezvigadzirwa zvemagetsi, PCB yakaitawo basa rinowedzera kukosha.Midziyo yemagetsi inopa maitiro ekuita kwepamusoro, kumhanya kwakanyanya, kureruka uye kutetepa.Seindasitiri yemhando dzakasiyana siyana, PCB yave imwe yeanonyanya kukosha matekinoroji emidziyo yemagetsi.Iyo PCB indasitiri inotora chinzvimbo chakakosha mumagetsi ekubatanidza tekinoroji.
