* To prevent release of the FPC due to its bending, use of the double sided FPC with copper foil on the back side is NOT RECOMMENDED.

1. This specification is a recommendation for the construction of the FH36 Series FPC (t=0.2

± 0.03)

2. For details about the construction, please contact the FPC manufacturers.
