This sheet type connector for inspection is anisotropic conductive sheet type, which consists of silicone rubber and metal fibers embedded densely into it.


[Industrial field]

Electronic Components, Semiconductor, Information devices, Automobile


MAF type Inter-Connector consists of multiple rows of metal fibers arranged symmetrically in a sheet of silicone rubber. MAF type connectors are used for extensive applications including assembly or inspection device.



  • Connection between PCB
  • Connection between devices and PCB 
  • Inspection for electrical parts and semiconductor devices


  • It's an anisotropic conductive sheet which consists of silicone rubber and metal fibers oriented densely into thickness direction of silicone.
  • It is used largely from packaging of electronic components to inspection with free shape by punching apparatus.


  • Anisotropic conductive sheet with metal fibers into silicone.
