Babban Material PCB Majalisar

Shenzhen Cirket Electronics Co., Ltd, ka daya-tasha bayani ga duk OEM da ODM PCB da PCBA bukatun. An kafa shi a cikin 2009, mun girma don zama babban mai ba da cikakken sabis na maɓalli ga abokan ciniki a duk duniya. Tare da layin 9 SMT da layin 2 DIP, muna da ikon ɗaukar kowane bangare na tsarin samarwa, daga haɓakawa da siyan kayan aiki, zuwa taro da dabaru.

PCB mai girma (Printed Circuit Board) yana nufin nau'in allon da'ira da aka ƙera don aiki a mitocin rediyo (RF) ko mitar microwave. Waɗannan mitoci yawanci suna fitowa daga ɗaruruwan megahertz (MHz) zuwa gigahertz da yawa (GHz) kuma ana amfani da su a aikace-aikace kamar tsarin sadarwa mara waya, tsarin radar, sadarwar tauraron dan adam, da sarrafa siginar dijital mai sauri.

PCBs masu girma-girma suna da halaye daban-daban da la'akari da ƙira idan aka kwatanta da daidaitattun PCBs:

1. Zabin Abu: PCBs masu ƙarfi galibi suna amfani da kayan musamman tare da kyawawan kayan lantarki don rage asarar sigina da kiyaye amincin sigina a mitoci masu yawa. Abubuwan gama gari sun haɗa da PTFE (Polytetrafluoroethylene) substrates kamar Teflon, da manyan laminates masu tsayi kamar FR-4 tare da ingantattun kaddarorin dielectric.

2. Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙira:An zaɓi kayan dielectric da aka yi amfani da su a cikin PCBs masu girma don ƙananan dielectric akai-akai (Dk) da ƙananan raguwa (Df), wanda ke taimakawa wajen rage girman sigina da murdiya a manyan mitoci.

3. Tsanani Mai Sarrafa: PCBs masu girma-girma sau da yawa suna buƙatar daidaitaccen iko na rashin ƙarfi don tabbatar da ingantaccen watsa sigina da rage girman tunani. Faɗin ganowa, kaurin dielectric, da jeri na tari na Layer an tsara su a hankali don cimma yanayin da ake so.

4. Gindi da Garkuwa: Ƙaƙwalwar ƙasa mai kyau da dabarun kariya suna da mahimmanci a ƙirar PCB mai girma don rage tsangwama na lantarki (EMI) da tabbatar da amincin sigina. Ana amfani da jirage na ƙasa, alamun gadi, da yaduddukan garkuwa don rage yawan magana da hayaniya.

5. Tsarin Layin Watsawa: Maɗaukakin sigina a kan PCBs sun fi kama da layukan watsawa maimakon alamun lantarki masu sauƙi. Ka'idodin ƙirar layin watsawa, kamar layukan ƙwanƙwasa mai sarrafawa, microstrip ko daidaitawar tsiri, da dabarun dacewa da impedance, ana amfani da su don haɓaka amincin sigina da rage lalata sigina.

6. Wuraren Rubuce-rubuce da Tafiya:A hankali sanyawa da sarrafa abubuwan da aka gyara da alamun sigina suna da mahimmanci a ƙirar PCB mai tsayi don rage tsayin sigina, guje wa lanƙwasa kaifi, da rage tasirin parasitic wanda zai iya lalata ingancin sigina.

7. Masu Haɗi Mai Girma:Ana zaɓar masu haɗin haɗin da aka yi amfani da su a cikin PCB masu girma don halayensu da suka dace da impedance da ƙarancin sakawa don rage tunanin sigina da kiyaye amincin sigina a manyan mitoci.

8. Kulawa da thermal: A cikin wasu aikace-aikacen mitoci masu ƙarfi, sarrafa zafin jiki ya zama mahimmanci don hana zazzaɓi na abubuwan haɗin gwiwa da kiyaye ingantaccen aiki. Ana amfani da magudanar zafi, ta hanyar thermal, da dabarun sarrafa zafin rana don watsar da zafi yadda ya kamata.
