Hi,
I would like to add a resistor based on solder characteristics to emulate solder joints to some simulations and haven't found any documentation online yet that provides all the information I'm looking for. Either that or I haven't understood it. I can't find this info on the manufacturer's spec. sheet or Googling "the solder type + resistance + temp co + company name." I know I can emulate the 1oz copper pcb tracks using online tools to calculate their resistance and temp co., when I get to that part.
One document View attachment 5aafaad2d3f1a2d5b47f962ef994840fd591.pdf says:
"b The alloy exhibited Ohmic behavior and has electrical resistivity 24.6 μΩ.cm at room temperature.
c The resistivity increased linearly with temperature and the temperature coefficient of resistivity was calculated and found to be 11x 10 ^-3 C-1."
Others, related to metal conductivity and resistivity don't seem to cover the specific solder I use.
engineering toolbox website says:
solder is: - ρ - (ohm m2/m) (Ω m) 15 x 10-8
This edaBoard thread says "solder has about tenfold resistivity of copper"
Which of these are sufficient for a simple model, and what about the temp co. aspect?
Is it unlikely to get such an exact match, and do you have to use general solder characteristics?
For Sn60Pb38Cu2, or just SnPb solder does anyone know of any helpful webs/tools/documents to obtain both parameters: resistance and temperature coefficient?
Thanks.
