enter image description hereI am having the issue of connecting my voltage regulator to the trace. The trace must be thick but the pins are too small. What is the best solution? I am using proteus. Does making a solder Paste shape work? Thank you!

A trace's resistance increases with length, and decreases with thickness. So the thickness is the more important the longer the trace is.

For a very short segment of the trace, the thickness does not change the total resistance by a noticeable amount. (Connections to through-hole pads are often deliberately made thinner to increase the thermal resistance; see Does adding thermal relief on PCB increase electrical resistance?)

So the shape of the connection does not really matter. The best solution is to not worry about it.

  • \$\begingroup\$ Assuming a current of 1 A, you would need a trace width of less than 5 mil for a temperature increase of 50 °C. \$\endgroup\$
