Copper Pads with Flex Ground
These self adhesive copper pads
can be attached on top of an IC
and connected to its ground pins
to create a convenient ground
plane for the probe to connect to.
When used with the flex ground, this method
provides an ideal ground connection for
probing signals with high frequency content. However, to maximize
the performance of this setup, you need to solder as many jumper
wires as is practical from the ground pins of the package to the
copper pad. The more ground connections, the less inductance in
the ground path and the higher the bandwidth capability of the
measurement. Insert the Flex Ground and bend it into a shape that
makes it easy to contact the copper ground pad on top of the
package.
NOTE
The bandwidth is highly dependent on the number of ground connections
between the copper pad and the device under test.
