I am wondering how do we attach cables to piezoelectric sensors. The soldering requirement is that it has to be done at low temperature. Do we have some conductive glue to attach the wires ? Please suggest which glue can be used to attach cables to piezoelectric sensors.

 

I think it should be OK to heat the sensor at 300 degrees for 1-2 seconds. Just make sure that the surface is clean and you use flux and thin solder, so you can do the action in short time.

 

normally soldering is used. but one need to be very careful to use low temperature solder or the thin metalization layer will be dissolved. or just get them with wires attached (risk free option)

 

FIRST, have the attaching wire already tinned before even approaching the piezo product. Have the piezo element on a heat absorbent flat surface. NEXT, use the smallest tip that carries the least heat enery, AND, use flux and low temperature solder. Hold the wire against the copper and put the iron on the wire. the solder should flow quickly, have something holding the wire in place and quickly remove the iron from the wire. It should not take more than two seconds. It is not a task for a beginner.
