XC3S50AN soldering condition

Jump to solution

Hello!
I have question about hand soldering condition for XC3S50AN-4TQG144C.
Is there wattage control condition for soldering iron in hand soldering condition?
If yes, could you let me know detail?

I checked the hand soldering conditions from "Implementation and Solder Reflow Guidelines for Pb-Free Packages".
My understanding for Hand Soldering conditions are following.
1) Temperature range : 350°C–375°C
2) Duration of up : 5 seconds

The wattage does not matter as such, its the temperature you need.
If its for home use, using leaded solder is slightly easier than lead free ( if you can get it )

Problems to lookout for,
the package moves as you solder it, A dab of glue under can help .
Solder whiskers between pins, ensure you have a good light and a microscope / magnifying glass to check.
The soldering iron loose heat to quick, a temperature controlled one is best,
Have a good supply of flux, and flux cleaner with a stiff brush.

Hi @mst_takahashi ,

 

I soldered many XC3S50AN-4TQG144C, I always used 350°C soldering iron and drag tecnique, you can see many video on youtube.

If you use good materials (soldering iron, flux and solder) you will have good results.

Good luck

Regards
