**Matters to Be Observed When Using This Product** 

## **Matters to Be Observed When Using This Product** 

## (PGS graphite sheet) 

## **Use environments** 

- This product (graphite sheet) is not designed for use in specific environments. Using the product in specific environments or service conditions described below, therefore, may affect the performance of the product. Please check the performance and reliability of the product first and then use the product. 

   - (1) Used in liquid, such as water, oil, chemicals, and organic solvents. 

   - (2) Used in a place exposed to direct sunlight, an outdoor place with no shielding, or a dusty place. 

   - (3) Used in a place where the product is heavily exposed to sea breeze or a corrosive gas, such as Cl2, H2S, NH3, SO2, or NOX. 

   - (4) Used in a contaminated state. 

   - (5) Used in a place where acid is present nearby. 

   - (6) Used in a temperature condition outside a specified working temperature range. 

   - (7) Used in a depressurized or vacuum atmosphere. 

- Temperatures of the graphite sheet in use vary depending on mounting conditions, service conditions, etc. Make sure to confirm that the temperature of the graphite sheet mounted on your board matches the specified temperature. 

## **Handling conditions** 

- The product is likely to suffer mechanical damage when dropped on the floor. Avoid using such a product. The graphite sheet is soft and is therefore easily scratched or damaged. Do not rub or hit the graphite sheet against a hard object. A stripe, folding line, etc., formed on the graphite sheet may affect its heat conductivity. 

- Do not reuse a graphite sheet having been used on a printed board and removed therefrom. A tearing load applied to the graphite sheet or a pointed object coming in contact with the sheet may tear the sheet or leave a hole thereon. Use the sheet with a protective material. 

- The graphite sheet may get hotter during its use. Do not touch the graphite sheet in use. Touching the graphite sheet with a bare hand may degrade the graphite sheet in performance. Do not do it. 

- Because the graphite sheet is conductive, you have to perform an insulation treatment on the graphite sheet if you want it to be insulative. Still, there is a concern that a conductive material in powder form may fall from the graphite sheet. Making the graphite sheet completely insulative, therefore, cannot be guaranteed. 

- The heat conductivity of the graphite sheet changes depending on how it is used. Conduct a heat conductivity test of the graphite sheet before using it to see if its heat conductivity meets the use purpose. 

## **Storage conditions** 

- Do not keep the graphite sheet in the following environments that may affect the performance of the graphite sheet. 

   - (1) Stored in a place where the product is heavily exposed to sea breeze or a corrosive gas, such as Cl2, H2S, NH3, SO2, or NOX. 

   - (2) Stored in a place where the graphite sheet is exposed to UV-rays (storing the graphite sheet in a dark place is recommendable). 

   - (3) Stored at a temperature different from the specified storage temperature. 

- The storage period of the graphite sheet is one year or less from completion of a shipment inspection. Use the graphite sheet before this storage period expires. 

- When the graphite sheet is incorporated in a circuit structure on the assumption that the graphite sheet is bonded, confirm the bonding performance of the graphite sheet before using it.
