PCB imatha kugawidwa mgulu limodzi, magawo awiri, bolodi losanjikiza, losinthasintha PCB bolodi ) Printed Circuit Board (PCB), yomwe imadziwikanso kuti Printed Circuit Board, ndichinthu chofunikira pakompyuta, ndichothandizira pazinthu zamagetsi, ndi omwe amagulitsa zamagetsi zamagetsi, chifukwa amapangidwa ndi ukadaulo wamagetsi, motero amatchedwanso Bokosi Loyang’anira “Losindikizidwa”. A PCB ndi mbale yopyapyala yokhala ndi ma circuits ophatikizika ndi zida zina zamagetsi.

Chimodzi, malinga ndi mtundu wosanjikiza wamagawo: ogawidwa pagulu limodzi, magawo awiri, ndi bolodi losanjikiza. Kawirikawiri bolodi la multilayer nthawi zambiri limakhala magawo 3-6, ndipo bolodi lama multilayer lovuta limatha kufikira zigawo zoposa 10.

(1) gulu limodzi

Pa bolodi loyambira losindikizidwa, magawo ake amakhala mbali imodzi ndipo mawaya amayang’ana mbali inayo. Chifukwa waya imawonekera mbali imodzi yokha, bolodi losindikizidwa limatchedwa gulu limodzi. Maseketi oyambilira adagwiritsa ntchito bolodi la dera chifukwa panali zoletsa zambiri pakapangidwe ka gulu limodzi (chifukwa panali mbali imodzi yokha, kulumikizana sikungadutse ndikuyenera kuyendetsedwa munjira ina).

(2) magawo awiri

Bungwe loyendetsa dera lili ndi zingwe mbali zonse ziwiri. Kuti mawaya mbali zonse azilankhulana, payenera kukhala kulumikizana koyenera pakati pa mbali ziwirizi, komwe kumatchedwa dzenje lotsogolera. Mabowo otsogolera ndi mabowo ang’onoang’ono m’bokosi losindikizidwa, lodzazidwa kapena lokutidwa ndi chitsulo, lomwe limatha kulumikizidwa ndi mawaya mbali zonse. Magulu awiri amatha kugwiritsidwa ntchito pama circuits ovuta kuposa mapanelo amodzi chifukwa malowa ndi akulu kuposa kawiri ndipo zingwe zimatha kulumikizana (zimatha kuvulazidwa mbali inayo).
