*Real tolerance of thickness dimension is on the order of ±20 µm (275 to 315 µm)
Note: Use of a thicker FFC results in a stiffer lock action and the lock is more easily released.
A factor that contributes to thicker FFC is the use of 250 µm stiffener which is thicker than the standard (188 µm) product. This
results in a total thickness of 357 µm.
When using FFC, control of FFC thickness becomes easy if you indicate to us the thickness of the stiffener.
