9. ! Caution
9-1.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.
(1)Aircraft equipment
(6)Disaster prevention / crime prevention equipment
(2)Aerospace equipment
(7)Traffic signal equipment
(3)Undersea equipment
(8)Transportation equipment (trains,ships,etc.)
(4)Power plant control equipment
(9)Applications of similar complexity and /or reliability requirements
(5)Medical equipment
to the applications listed in the above
9-2. Caution for product’s ratings
Don’t use our products over their rating current, 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 and open circuit.
9-3. 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.
9-4.Mounting Density
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.

9-5. Addition fail-safe function to your products
P5/5
Be sure to add an appropriate fail-safe function on your product to prevent a second damage that may be caused by
the abnormal function or the failure of our product.
10. Notice
This product is designed for adhesive with conductive glue, so we can’t guarantee for other connecting method.
If you plan to take another connecting method, please contact us.
10-1. 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.
