silver ink screen printed electrodes. Rather than making
the lead attachment near the sensor, the Piezo polymer
tail extends from the active sensor area as flex circuit
material with offset traces. This gives a very flat, flexible
lead with a connector at the end.
The FDT elements are available in a variety of
different sizes and thicknesses. They are available without
a laminate (FDT), with a laminated (0.005” mylar) on one
side (FLDT) or with tape release layer adhesive (FDT with
adh) in the sensor area.

The connector pins on the FDT sensors can be directly soldered to a PCB with a reasonable level of care. This
component cannot withstand high temperatures (>80°C) and therefore soldering of the pins to a PCB must be
done quickly. A heat sink clamped to the interface area between the film and the crimps will take the heat away
from the film. Pre-tin the pins and then quickly solder them to the board. Do not allow the soldering iron to touch
the film and do not use a dwell time of more than 5 seconds on the pins. Low temperature solder can also be
used.
