What does the 'cost vs complexity trade-off' mean in PCB design?
It means balancing the expense of making a PCB with how complex its design is. More complex designs usually cost more to produce.

Why does increasing PCB complexity often increase cost?
Because complex PCBs need more layers, finer details, and special materials, which take more time and resources to make.

What usually happens to PCB cost when complexity increases?
✗ Incorrect
More complex PCBs require more materials and manufacturing steps, so cost goes up.
Which factor can reduce PCB cost?
✗ Incorrect
Simpler designs use fewer resources and are cheaper to make.
What is a trade-off in PCB design?
✗ Incorrect
Trade-off means balancing cost and complexity to meet goals.
Which is NOT a reason complexity increases PCB cost?
✗ Incorrect
Simpler layout usually lowers cost, not increases it.
What strategy helps manage cost with needed complexity?
✗ Incorrect
Modular design breaks complexity into parts, controlling cost.
