Soldering Instructions

General Soldering Notes

1. High soldering temperatures and long soldering

times can cause leaching of the termination and

adversely affect adhesion. These conditions can

also decrease capacitance value. Use the above

recommended solder temperature cycle.

2. Due to the mechanical characteristic of ceramic

composition, aggressive thermal shock will

degrade performance. Preheat the assembly

before soldering using the above solder

temperature profile as a guide.

3. Use mild flux (less than 0.2% by weight of

Chlorine), preferable rosin based. If water soluble,

wash thoroughly to assure all residue is removed

from the underside of components.

4. Ultrasonic Cleaning

When using an ultrasonic cleaning method,

the following range is recommended:

Frequency: Not to exceed 28kHz

Output Power: Not to exceed 20W/liter

Cleaning Time: 5 minutes max
