I am trying to learn to layout a PCB. I want provide VCC voltage to transistors at 1.5amps max. Using an online calculator the width I require for 0.5ounce copper board is 1mm. I oversized the PCB trace for VCC to 1.5mm. P1 is the header pin where I supply the board with VCC. Will using such a large trace post a problem when soldering ? I googled PCB design rules, and they mentioned that a thermal relief is a must for ground plane to make it easier to solder. But I can't find info if large traces will be hard to solder too.
