Salut Yannick,

Datapaq ont un logiciel qui te permet de prédire le profil de température à
partir du CAD.
Je ne l'ai pas essayé, mais il semble très bien.

Subject: [TN] Thermal Mass


Hi,

  For quiet long I've heard people said that the reflow profile must be
change for each board depending of the thermal mass of the board.  My
question is how do you calculate this Thermal mass? Or to have a good
profile do you take all the datasheet of the component on the board and
take
an average of that?

 Hope you can help me with this issue.

Thanks You
Yannick Brisson
