Bambancin Tsakanin PCBs na yumbura da PCB na FR4 na Gargajiya
Kafin mu tattauna wannan batu, bari mu fara fahimtar menene PCBs na yumbura da menene FR4 PCBs.
Kwamitin da'ira na yumbu yana nufin nau'in allon da'ira da aka ƙera bisa kayan yumbu, wanda kuma aka sani da Ceramic PCB (allon da'ira). Ba kamar gilashin fiber na yau da kullun da aka ƙarfafa filastik (FR-4), allunan da'irar yumbu suna amfani da kayan yumbura, wanda zai iya samar da kwanciyar hankali mafi girma, ƙarfin injina, mafi kyawun abubuwan dielectric, da tsawon rayuwa. Ana amfani da PCBs yumbura a cikin matsanancin zafin jiki, mitoci mai ƙarfi, da da'irori masu ƙarfi, kamar fitilun LED, amplifiers, lasers semiconductor, transceivers RF, firikwensin, da na'urorin microwave.
Hukumar da'ira tana nufin ainihin abu don kayan haɗin lantarki, wanda kuma aka sani da PCB ko allon da'ira. Shi mai ɗaukar kaya ne don haɗa kayan aikin lantarki ta hanyar buga samfuran kewayen ƙarfe akan abubuwan da ba su da ƙarfi, sannan ƙirƙirar hanyoyin gudanarwa ta matakai kamar lalata sinadarai, jan ƙarfe na lantarki, da hakowa.
Mai zuwa shine kwatancen tsakanin yumbura CCL da FR4 CCL, gami da bambance-bambancen su, fa'idodi da rashin amfani.

Ceramic PCB
Filayen aikace-aikace na abubuwa daban-daban:
Alumina Ceramic (Al2O3): Yana da kyakkyawan rufi, kwanciyar hankali mai zafi, taurin, da ƙarfin inji don dacewa da na'urorin lantarki masu ƙarfi.
Aluminum Nitride Ceramics (AlN): Tare da haɓakar haɓakar thermal mai ƙarfi da kwanciyar hankali mai kyau, ya dace da na'urorin lantarki masu ƙarfi da filayen hasken LED.
Zirconia yumbura (ZrO2): tare da babban ƙarfi, babban ƙarfi da juriya, ya dace da kayan aikin lantarki mai ƙarfi.
Filin aikace-aikace na matakai daban-daban:
HTCC (High Temperature Co fired Ceramics): Ya dace da babban zafin jiki da aikace-aikace masu ƙarfi, kamar wutar lantarki, sararin samaniya, sadarwar tauraron dan adam, sadarwa ta gani, kayan aikin likita, na'urorin lantarki na kera motoci, petrochemical da sauran masana'antu. Misalai na samfur sun haɗa da manyan LEDs, amplifiers na wutar lantarki, inductor, na'urori masu auna firikwensin, capacitors na makamashi, da sauransu.
LTCC (Low Temperature Co fired Ceramics): Ya dace da kera na'urorin microwave kamar RF, microwave, eriya, firikwensin, tacewa, rarraba wutar lantarki, da sauransu. lantarki da sauran filayen. Misalai na samfur sun haɗa da na'urorin lantarki, na'urorin eriya, na'urori masu auna matsa lamba, na'urori masu auna gas, na'urori masu hanzari, matattarar microwave, masu rarraba wuta, da sauransu.
DBC (Direct Bond Copper): Ya dace da zubar da zafi na na'urori masu ƙarfi masu ƙarfi (kamar IGBT, MOSFET, GaN, SiC, da dai sauransu) tare da kyakkyawan yanayin zafi da ƙarfin injina. Misalan samfur sun haɗa da na'urorin wutar lantarki, na'urorin lantarki, masu kula da abin hawan lantarki, da sauransu.
DPC (Direct Plate Copper Multilayer Printed Board Board): galibi ana amfani dashi don watsar da zafi na fitilun LED masu ƙarfi tare da halayen babban ƙarfi, haɓakar thermal, da babban aikin lantarki. Misalan samfurin sun haɗa da fitilun LED, LED UV, LED COB, da sauransu.
LAM (Laser Activation Metallization for Hybrid Ceramic Metal Laminate): ana iya amfani dashi don ɓatar da zafi da haɓaka aikin lantarki a cikin fitilun LED masu ƙarfi, na'urorin wuta, motocin lantarki, da sauran filayen. Misalan samfur sun haɗa da fitilun LED, na'urorin wutar lantarki, direbobin motocin lantarki, da sauransu.
