What is the temperature calculation for soldering pins onto PCB edge pads?

Click For Summary
SUMMARY

The discussion focuses on calculating the temperature at IC pins when soldering pins onto PCB edge pads. The user, Kamath, specifies that the edge pads are connected to an IC via copper traces measuring 25 mil in length, 10 mil in width, and 0.7 mil in thickness. He intends to heat the pins to 300 degrees Celsius for 10 seconds and seeks to determine the resultant temperature at the IC pins. Although he has calculated the thermal resistance of the copper trace, he requires further assistance to complete the temperature calculation.

PREREQUISITES
  • Understanding of thermal resistance calculations
  • Knowledge of PCB design principles

I have a PCB with edge pads to which I have to solder pins.
The edge pads are connected to another IC through copper traces of length say 25 mil. Copper traces are of width 10mil and thickness 0.7 mil.

Basically I want to calculate the temperature at the IC pins when I solder the pins onto the edge pads.
Let us say if I heat the pins (at the edge pad) to 300 degree celsius for 10seconds time.
I would like to calculate temperature at the other end of the copper trace in this case?

I calculated the thermal resistance for the above copper trace, but couldnot proceed further.

Any clue for this problem will be of great help to me.

Regards,
Kamath

Without a diagram, this problem seems impossible to solve.
