8. SOLDERING AND MOUNTING :

8-1. Soldering

Mildly activated rosin fluxes are preferred. Our 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.

8-1.1 Lead Free Solder Re-flow :

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

8-1.2 Soldering Iron (Figure 2) :

Products attachment with 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.

Note :

a) Preheat circuit and products to 150° C.

b) 355° C tip temperature (max)

d) 1.0mm tip diameter (max)

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

f) Limit soldering time to 4-5 secs.

c) Never contact the ceramic with the iron tip

Application Notice

1. Storage Conditions :

To maintain the solderabililty of terminal electrodes :

a) Temperature and humidity conditions : Less than 40° C and 60% RH.

b) Recommended products should be used within 12 months from the time of delivery.

c) The packaging material should be kept where no chlorine or sulfur exists in the air.

2. Transportation :

a) Products should be handled with care to avoid damage or contamination from perspiration and skin oils.

b) The use of tweezers or vacuum pick up is strongly recommended for individual components.

c) Bulk handling should ensure that abrasion and mechanical shock are minimized.
