Game da PCB, shine abin da ake kira buga kewaye hukumar, wanda yawanci ake kira katako mai wuya. Jiki ne mai goyan baya tsakanin kayan lantarki da kuma muhimmin bangaren lantarki. PCB gabaɗaya yana amfani da FR4 azaman kayan tushe, wanda kuma ake kira dattin allo, wanda ba za a iya lanƙwasa ko lanƙwasa ba. Ana amfani da PCB gabaɗaya a wuraren da babu buƙatar lanƙwasa, kamar uwayen kwamfuta da uwayen wayar hannu.

FPC a haƙiƙa wani nau’i ne na PCB, amma ya bambanta da allon da’ira na gargajiya. Kira shi allo mai laushi, kuma cikakken suna shine allon kewayawa mai sassauƙa. FPC gabaɗaya yana amfani da PI azaman kayan tushe, wanda shine sassauƙan abu wanda za’a iya lanƙwasa da jujjuya shi yadda ake so. FPC gabaɗaya yana buƙatar jujjuyawar maimaitawa da haɗa wasu ƙananan sassa, amma yanzu ya fi haka. A halin yanzu, wayoyi masu wayo suna tunanin yin lankwasa rigakafi, wanda ke buƙatar amfani da FPC, fasaha mai mahimmanci.

A gaskiya ma, FPC ba kawai kwamiti mai sassauƙa ba ne, amma kuma hanya ce mai mahimmanci ta ƙira ta haɗaɗɗen tsarin kewaye. Ana iya haɗa wannan tsarin tare da wasu samfuran samfuran lantarki don gina nau’ikan aikace-aikace daban-daban. Saboda haka, daga wannan batu a kan Look, FPC da PCB sun bambanta sosai.

Don PCB, sai dai idan an yi da’irar ta zama nau’i mai girma uku ta hanyar manne tukwane, allon kewayawa gabaɗaya ya faɗi. Saboda haka, don yin cikakken amfani da sararin samaniya mai girma uku, FPC shine mafita mai kyau.
