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

AI Thread Summary
To calculate the temperature at the IC pins when soldering pins onto PCB edge pads, one must consider the thermal resistance of the copper traces connecting the pads to the IC. The user has already calculated the thermal resistance but is unsure how to proceed with determining the temperature at the IC pins after heating the edge pads to 300 degrees Celsius for 10 seconds. Without a diagram, the complexity of the problem increases, making it challenging to visualize heat transfer along the traces. Additional information on heat dissipation and the specific thermal properties of the materials involved may be necessary for an accurate calculation. Overall, understanding the thermal dynamics in this scenario is crucial for successful soldering.

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 celcius 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.
 

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...
