91 / 104 page  !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. Soldering Gradual cooling (in air) Preheating (in air) 1 to 2 min. 200 100 0 240°C 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. (c) In the case of repeated soldering, the accumulated 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.)
