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 capaci-
tance 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
