[Solved] You have four parallel bus traces with lengths 48mm, 52mm, 50mm, and 55mm.... What lengths should the 48mm and 50mm traces be adjusted to? | PCB Design

PCB Design - Advanced Routing Techniques

You have four parallel bus traces with lengths 48mm, 52mm, 50mm, and 55mm. You want to length match them by adding serpentine traces only to the shortest two. What lengths should the 48mm and 50mm traces be adjusted to?

ABoth adjusted to 55mm

B48mm to 52mm, 50mm to 55mm

CBoth adjusted to 52mm

D48mm to 55mm, 50mm to 52mm

Step-by-Step Solution

Solution:

Step 1: Identify the longest trace length
The longest trace is 55mm.
Step 2: Adjust shortest traces to longest length
Only the 48mm and 50mm traces are adjusted to 55mm to match the longest.
Final Answer:
Both adjusted to 55mm -> Option A
Quick Check:
Shortest traces lengthened to longest [OK]

Quick Trick: Lengthen shortest traces to longest trace length [OK]

Common Mistakes:

MISTAKES

Adjusting to intermediate lengths instead of longest
Mixing up which traces to adjust
Trying to shorten longer traces
