Caution
9-1.Rating
Do not use products beyond the Operating Temperature Range and Rated Current.
9-2. Operating Environment
(1)Don’t use our products over the operating temperature, because it may make the deterioration of their electric
characteristics. In worst case, it may cause smoke from the adhesive because of the excessive heat.
(2)Do not use this product in the corrodible atmosphere (acidic gases, alkaline gases, chlorine, sulfur gases, organic
gases and etc.), because the atmosphere may cause deterioration of the electrical characteristic because of the
corrosion of the inner electrodes and outer electrodes and deterioration of the adhesive.
9-3. Mounting Density
Don’t be soldered on the substrate. This product must be mounted on the substrate with conductive glue.
Add special attention to radiating heat of some products with heating when mounting our product
near the products.
The excessive heat by other products may cause deterioration of our product’s characteristics or incorrect
operation, so
be sure to use our product under the operating temperature including the heat from other products.
9-4.Fail Safe
Be sure to provide an appropriate fail-safe function on your product to prevent from a second damage
that may be caused by the abnormal function or the failure of our products.
9-5.Limitation of Applications
Please contact us before using our products for the applications listed below which require especially high
reliability for the prevention of defects which might directly cause damage to the third party’s life,
body or property.

How to mount this product on a board with conductive glue
Please refer to the figure and table below which shows the method of recommended mounting
with conductive glue.
( We recommend using a mounting machine to mount this product.)
Please coat print pats with recommended conductive glue “PC3000” manufactured by Heraeus with using metal
mask and metal squeegee, and then mount our products on the substrates with a mount machine or human hand.
Please put the substrates into a oven (140
～
150
℃
) for 30 minutes in order to cure the adhesive. Please check
whether the chips and the substrates are connected with the conductive glue or not and there is
no electrically short of the conductive glue.

10-2.Storage Conditions
(1)Storage period
Use the products within 6 months after delivered.
Adhesive performance should be checked if this period is exceeded.
(2)Storage conditions
Products should be stored in the warehouse on the following conditions.
Temperature : -10°C to 40°C
Humidity
: 15% to 85% relative humidity
No rapid change on temperature and humidity
Don’t keep products in corrosive gases such as sulfur, chlorine gas or acid, or it may cause oxidization
of electrode, resulting in poor solderability.
Products should be stored on the palette for the prevention of the influence from humidity, dust and so on.
Products should be stored in the warehouse without heat shock, vibration, direct sunlight and so on.
Products should be stored under the airtight packaged condition.
(3)Delivery
Care should be taken when transporting or handling product to avoid excessive vibration
or mechanical shock.
