Application Notes
PREHEAT & SOLDERING
The rate of preheat in production should not exceed 4°C/
second and a recommended maximum is about 2°C/second.
Temperature differential from preheat to soldering should not
exceed 100°C.
For further specific application or process advice, please consult
AVX.
COOLING
After soldering, the assembly should preferably be allowed
to cool naturally. In the event of assisted cooling, similar
conditions to those recommended for preheating should be
used.
HAND SOLDERING & REWORK
Hand soldering is permissible. Preheat of the PCB to 150°C is
required. The most preferable technique is to use hot air sol-
dering tools. Where a soldering iron is used, a temperature
controlled model not exceeding 30 watts should be used and
set to not more than 260°C.

CLEANING RECOMMENDATIONS
Care should be taken to ensure that the devices are
thoroughly cleaned of flux residues, especially the space
beneath the device. Such residues may otherwise become
conductive and effectively offer a lossy bypass to the device.
Various recommended cleaning conditions (which must be
optimized for the flux system being used) are as follows:
