Heat sinks do not stick to motor controller chips

[elfa45]

Am putting the electronics together. I am unable to make the heat sinks stick to the motor controller shield chips.
I removed the backing and applied to the chips. They stick for awhile but any movement of the board might cause them to fall off. The tape still feels sticky but does not hold.

Is there another option for applying the heat shields?

Wipe the chips with alcohol. They may not have been cleaned properly. Trying several times and falling off, the tape on yours is deteriorated some. If it doesn't stick, thermal epoxy is best.
