Using 4 oz copper means our SMD resistors & caps will not be soldered properly?

Hello,
We are doing a 3 channel, surface mount Buck LED driver (3x 165W) , which is 495W total. The room on the PCB for this is just 60mm x 70mm.
So as to keep the components cool, we wish to use 4 oz copper…but will this mean that 0603 resistors will not be soldered properly? (there are 0603 resistors and caps near the PWM controller).

Nope, as long as the board is profiled correctly for the reflow oven there should be no problems.
