#103455 - Resistance calculation for thrmal relief
Responding to: ???'s previous message
Sasha Jevtic said:


As you select the design of your thermal reliefs, keep in mind that you are basically trading off between two attributes: electrical resistance of the connection vs. ease of soldering. Calculate the resistance of your thermal reliefs and see what you think. Be careful about using them for connections that will be carrying a lot of current.

Can you tell me how to calculate the resistance of the thermal relief's.

Does it depend only on the flow of current through it?.

if so, my circiut has current flow only in few mA to 1A max.
