Kayan Sadarwa PCB
Don rage nisan watsa siginar da rage asarar watsa siginar, allon sadarwar 5G.
Mataki-mataki zuwa manyan wayoyi masu yawa, kyakkyawan tazarar waya,tya ci gaba shugabanci na micro-budewa, bakin ciki irin da high aminci.
Haɓakawa mai zurfi na fasahar sarrafawa da tsarin masana'anta na nutsewa da da'irori, ƙetare shingen fasaha.Zama ƙwararren masana'anta na 5G high-end sadarwa PCB board.
