I have this IC here wherein pin 6 will take around 3A of current and a quick use of some online calculator says that the trace width for 3A on a 1oz. cu is 140mil (70mil for 2oz). On pin six it is impossible for me to place a 140 mil trace as it would hit the pads beside it. Even if we use a 2oz cu it would still have to taper in, as shown in the picture below.
Is what I did okay? Would the traces handle the current? I have noticed it to be also the case for BGA PMICs rated for high amps wherein I could not place a enough copper near where pads and will have to taper out.
