Product Overview

At the same time when a shielding film on FPC and a metallic stiffener are bonded, the FPC GND and external GND can be connected through the shielding film and metallic stiffener. Accordingly, this product can improve the degree of freedom in the design of FPC wiring, and because there is no need for coverlay opening, processes can be simplified and smoothness of FPC can be secured.
* We do not guarantee any combination with other products than TATSUTA-manufactured shielding films.

Features

  • Enables connection with external GND through the shielding film and metallic stiffener

    Enables high density wiring design of FPC.
  • Enables across-the-board shield

    Enables shield on the periphery of the stiffener because it can be bonded on the shielding film.
  • Reduces surface roughness of FPC

    Because there is no need for coverlay opening, roughness of the component mounting surface can be reduced.
