Why is it important to understand the cost vs complexity trade-off when designing PCBs for mass production?

ABecause small cost increases multiply over large volumes
BBecause complexity always reduces production time
CBecause cost is fixed regardless of design
DBecause complexity does not affect manufacturing
Step-by-Step Solution
Solution:
  1. Step 1: Consider mass production scale

    Small cost changes per unit become large when multiplied by volume.
  2. Step 2: Understand trade-off importance

    Balancing cost and complexity avoids excessive total expenses.
  3. Final Answer:

    Because small cost increases multiply over large volumes -> Option A
  4. Quick Check:

    Mass production cost impact = small cost * large quantity [OK]
Quick Trick: Small cost changes add up in mass production [OK]
Common Mistakes:
MISTAKES
  • Ignoring volume effect
  • Assuming fixed cost
  • Thinking complexity reduces time always
