Hamwe nogutezimbere ikoranabuhanga rya PCB no kwiyongera kwabaguzi kubicuruzwa byihuse kandi bikomeye, PCB yahindutse kuva mubuyobozi bwibanze bwibice bibiri ihinduka ikibaho gifite ibice bine, bitandatu kandi bigera kumurongo icumi kugeza kuri mirongo itatu ya dielectric nuyobora..Kuki wongera umubare wibice?Kugira ibice byinshi birashobora kongera imbaraga zo gukwirakwiza ikibaho cyumuzunguruko, kugabanya inzira nyabagendwa, kuvanaho amashanyarazi akoreshwa no gushyigikira ibimenyetso byihuta.Umubare wibice bikoreshwa kuri PCB biterwa na porogaramu, inshuro ikora, ubunini bwa pin, nibisabwa byerekana ibimenyetso.

Mugukurikirana ibice bibiri, igice cyo hejuru (ni ukuvuga, layer 1) gikoreshwa nkikimenyetso.Ibice bine byuzuye bikoresha hejuru no hepfo (cyangwa icya 1 nicya 4) nkibimenyetso.Muriyi miterere, ibice 2 na 3 bikoreshwa nkindege.Prereg layer ihuza ibice bibiri cyangwa byinshi byikubye kabiri hamwe kandi ikora nka dielectric hagati yabyo.Ibice bitandatu PCB yongeramo ibice bibiri byumuringa, naho icya kabiri nicya gatanu bikora nkindege.Igice cya 1, 3, 4, na 6 bitwara ibimenyetso.

Komeza ujye kumurongo itandatu, imbere imbere ibiri, itatu (iyo ari ikibaho cyibice bibiri) na kane ya kane (iyo ari ikibaho cyibice bibiri) nkurwego rwibanze, na prereg (PP) ni yashyizwe hagati yimbaho ​​yibanze.Kubera ko ibikoresho byabanjirije bitarakira neza, ibikoresho biroroshye kuruta ibintu byingenzi.Uburyo bwo gukora PCB bukoresha ubushyuhe nigitutu kuri stack yose hanyuma bigashonga prereg na core kugirango ibice bishobore guhuzwa hamwe.

Ikibaho kinini cyongeramo umuringa na dielectric ibice kuri stack.Muri PCB igizwe n'umunani, imirongo irindwi y'imbere ya dielectric kole ibice bine bya planari hamwe na bine byerekana ibimenyetso hamwe.Ibibaho icumi kugeza kuri cumi na bibiri byongera umubare wibice bya dielectric, bigumana ibice bine byateganijwe, kandi byongera umubare wibimenyetso.
