5. Soldering and Mounting

Mildly activated rosin fluxes are preferred. The minimum amount of solder can lead to damage from the stresses caused by the difference in

coefficients of expansion between solder, chip and substrate. The

terminations are suitable for all wave and re-flow soldering systems. If hand soldering cannot be avoided, the preferred technique is the utilization of hot air soldering tools.

Recommended temperature profiles for re-flow soldering in Figure 1.

Products attachment with a soldering iron is discouraged due to the inherent process control limitations. In the event that a soldering iron must be

employed the following precautions are recommended.

?Preheat circuit and products to 150℃

?Never contact the ceramic with the iron tip

?Use a 20 watt soldering iron with tip diameter of 1.0mm

?280℃ tip temperature (max)

?1.0mm tip diameter (max)

?Limit soldering time to 3 sec.

6. Packaging Information

◆Tape Specification:

◆Reel Specification: (7’’, Φ180 mm)

7. Storage and Transportation Information

◆Storage Conditions

To maintain the solderability of terminal electrodes:

1. Temperature and humidity conditions: -10~ 40℃ and 30~70% RH.

2. Recommended products should be used within 6 months from the time

of delivery.

3. The packaging material should be kept where no chlorine or sulfur

exists in the air.

◆Transportation Conditions

1. Products should be handled with care to avoid damage or

contamination from perspiration and skin oils.

2. The use of tweezers or vacuum pick up is strongly recommended for

individual components.

3. Bulk handling should ensure that abrasion and mechanical shock are

minimized.
