Can I reduce the number of layers on a pcb by making the board larger?
I have a design that uses DDR3 RAM where I need to match trace lengths. When the design is having RAM, 4 layers pcb is usually used, but it is too expensive to me. Can I use a larger 2 layers pcb instead?
Because 2-4 layer is a large price difference? Can anyone tell me the reason of the price difference?
