3. Soldering Conditions
(1) Solder Paste
To remove the flux after soldering, observe the following
points in order to avoid deterioration of the characteristics
or any change to the external electrode's quality.
(1) Cleaning Conditions
(2) Drying
In your mounting process, observe the following points in
order to avoid deterioration of the characteristics or
destruction of this product. The mounting quality of this
product may also be affected by the mounting conditions,
shown in the points below.
(1) Printing Conditions of Solder Paste
Notice (Soldering and Mounting) PRF18/21 Series
A sufficient cleaning should be applied to remove flux completely.
(a) Flow Soldering: Use Sn:Pb=60:40wt%,
(b) Reflow Soldering: Use Sn:Pb=60:40wt%,
2-propanol
After cleaning, promptly dry this product.
(a) Recommended thickness of solder paste printing
(b) After soldering, the solder fillet should be a height
(c) Too much solder causes strong mechanical stress
