Frequently Asked Questions (continued)
Question:
What mounting techniques and materials are recommended to achieve the best high
frequency response?
Response:
To achieve the best frequency response, we recommend mounting the accelerometer
directly to the structure to be measured. An adhesive can be used to secure the accelerometer. Take
precautions not to short the output pads underneath the circuit board. Good frequency response can also
be achieved by mounting the accelerometer onto a ceramic or hybrid circuit board. FR4 boards should
be avoided for applications requiring wide bandwidth measurements since the FR4 material can impart a
resonance to your measuring system. If attaching wires to the output pads then these need to be
properly secured/anchored at regular intervals to minimize cable motion that can add noise and
resonances to the output signal.
Question:
What is the material composition of the plating on the solder pads?
Response:
The circuit board traces are Titanium-Tungsten plated with Nickel and Gold. 50micro-inches
min of Au (99.9% pure gold per MIL-G-45204, Type III, grade A) over 50-350micro-inches of Ni (per
