!Caution/Notice

(3) Standard Temperature Profile for Soldering

(a) Insufficient preheating may cause a crack on the

ceramic body. The difference between preheating

temperature and maximum temperature in the profile

should be 100°C.

(b) Rapid cooling by dipping in solvent or by other

means is not recommended.

Reflow Soldering Conditions

* In the case of repeated soldering, the accumulated soldering

time should be within the range shown in "(2) Allowable

Soldering Temperature and Time."

*20 sec.

Preheating: 150±10°C, 1 to 2 minutes

Soldering: 240°C, 20 sec.

(4) There may be a risk of unexpected failures

(tombstone, insufficient solder-wetting, etc.) in the

mounting process, caused by the mounting conditions.

Please make sure that this product is correctly

mounted under the specified mounting conditions.

(2) Allowable Soldering Temperature and Time

(a) Solder within the temperature and time

combinations, indicated by the slanted lines in the

graphs at right.

(b) Excessive soldering conditions may cause

dissolution of metallization or deterioration of

solder-wetting on the external electrode.

soldering time should be within the range shown at

right. (For example, Reflow peak temperature: 260°C,

twice –> The accumulated soldering time at 260°C is

within 15sec.)
