GENERAL RECOMMENDATIONS FOR SOLDERING CERAMIC STACKED CAPACITORS
In general, Presidio recommends against hand soldering for this type of large ceramic device. However, if the
customer cannot avoid hand soldering, it should be done with care to avoid thermally cracking the parts.
Soldering of these parts to the circuit board, if done in a careless manner, can be the most likely source of
reliability problems.
Preheating and Mounting.
For reflow, the parts should be preheated to within 50ºC to 60ºC to the
reflow temperature, or as close as is practical. A convection-style reflow oven with nitrogen is ideal.
During reflow, the heat-up and cool-down rates (dT/dt) should be kept well under 4ºC/sec, and preferably
under 2ºC/sec.
Hand Soldering.
If hand soldering must be used, preheat the parts as recommended above. A hot-air
gun is an ideal tool for this procedure. When hand soldering, avoid excessive heat, and keep the tip of
the solder iron as far away from the ceramic as possible. As an example, for through-hole leaded parts,
solder from the backside of the board. This will minimize the risk of thermally cracking the ceramic.
After soldering, allow the parts to air cool to room temperature before cleaning.
Leads.
The leads do not need to be pre-tinned as they have already been tinned with Sn63 as part of our
process. For special code ‘Y’, leads are coated with silver.
In addition to the above, the following rules apply:
1. Never dip the stacked capacitors into a solder pot (for pre-tinning, for example).
2. Never allow an operator to touch-up a solder joint with a soldering iron.
IN ACCORDANCE WITH MIL-PRF-49470
The following precaution should be followed to prevent THERMAL SHOCK
“Precautionary Note: Capacitors covered by this specification sheet are very susceptible to
thermal shock damage due their large ceramic mass. Temperature profiles used should provide
adequate temperature rise and cool-down time to prevent damage from thermal shock.”
SPECIAL STACKS AND LEADS
Presidio can tailor the lead configuration to your needs. We also offer special shapes that optimize the
volume available (semi-round and round shapes). Other shapes are also available.
