Thin-Film RF/Microwave Capacitor Technology
Automotive Grade Accu-P® Series
Application Notes
PREHEAT & SOLDERING
RECOMMENDED REFLOW SOLDERING PROFILE
COMPONENTS WITH SNPB TERMINATIONS
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 KYOCERA
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 soldering 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:
