. For more information on Gap Pad modulus refer to
Bergquist Application Note #116.
The resultant thickness of the Gap Pad will determine the thermal resistance.
Subtracting the initial gap pad thickness by the deflection value, obtained above,
will give the resultant thickness. Refer to the graph below to obtain the thermal
resistance of the material.
Gap Pad VO is available in die-cut parts and sheets.
Standard sheet size is 8鈥?X 16鈥? with or without adhesive.
