I'm routing a PCB. Currently, all power traces are 20 mils. A QFP chip on the board requires multiple voltage rails to operate, I found the easiest solution is passing a power trace through a pin on the chip (the
1.8VI net in the screenshot).
However, it means the trace is as wide as the pin itself. Will it acting as a heatsink and create a solderability / thermal balance problem in hand soldering or reduce the yield in reflow soldering? Should I reduce the trace width when it's passing a pin for thermal relief?
