Side Pads on Crystal Oscillators

What are Side Pads?

• Side pads are metal pads on the side of crystal oscillator packages. Pads are generally on the short side of the package.

• ‍There are also metal pads extending from the soldering pads on the bottom of the package. These pads are not considered side pads in this context.

• Side pads make electrical connections to the crystal blanks inside. 

• Side pads are used to measure electrical characteristics of crystal blanks after assembly in order to further assure quality of the blanks before shipment.

Application Consideration

• When soldering the crystal oscillators onto boards, make sure the side pads are not shorted or in contact to soldering pads. 

• If the side pads come to contact with the soldering pads such as GND or Vdd, it would cause the units to not oscillate or generate unstable output.
