## **Soldering Information**
## **Reflow soldering : Temperature profile**
**1.** The reflow soldering can be implemented in two times complying with the following diagram.All the temperatures in the product must be within the diagram.
**2.** The recommended thickness of the metal mask for screen printing is between 0.2 and 0.25 mm.

## **Manual soldering**
The manual soldering should not be applied to the products, otherwise the housing may be deformed and/or the Au plating may be peeled off by heat.
## **Other notes**
The use of infrared lamp causes the temperature at the resin to rise particularly too high.
All the temperatures in the product must be within the above diagram. Do not immerse the resin part into the solder. Even if within the above temperature diagram, there is a possibility that the gold wire in the products is broken in case that the deformation of PC board gives stress to the products.
Please confirm the conditions (including material and method of flux and cleaning) of the reflow soldering fully by actual solder reflow machine prior to the mass production use.

## **Storage**
## **Storage conditions**
- To protect the product from the effects of humidity until the package is opened, dry-box storage is recommended. If this is not possible, store the product under the following conditions: Temperature: 10 to 30 °C Humidity: 60% RH max.
## **Treatment after open**
**1.** Reflow soldering must be done within 48 hours stored at the conditions of humidity 60% RH or less and temperature 10 to 30°C.
**2.** If the product must be stored after it is unpacked, store it in a dry box or reseal it in a moisture-proof package with desiccant at a temperature of 10 to 30°C and a humidity of 60% RH or less. Even then, mount the product within one week.
## **Baking**
In case that it could not carry out the above treatment, it is able to mount by the following baking treatment. However baking treatment shall be limited only 1 time.
Recommended conditions: 60°C for 24 to 48 hours (reeled one)
- 100°C for 8 to 24 hours (loose one)
