💡 Hint

Common Mistakes

Choosing a trace width too small to handle current.

Using a value larger than necessary, wasting board space.

The minimum trace width is set to 10 mils to ensure proper current capacity and manufacturability.

💡 Hint

Common Mistakes

Setting spacing too small causing shorts.

Setting spacing too large wasting PCB area.

6 mils spacing is a typical minimum to prevent shorts and ensure manufacturability.

💡 Hint

Common Mistakes

Using a string instead of a number.

Using a word instead of a numeric value.

The trace width must be a numeric value without quotes. 12 is the correct integer value.

💡 Hint

Common Mistakes

Swapping width and spacing values.

Using values too small for manufacturing.

Minimum trace width is set to 8 mils and spacing to 6 mils to balance performance and manufacturability.

5fill in blank

hard

Fill all three blanks to define a rule with minimum trace width 12 mils, minimum spacing 8 mils, and clearance 10 mils.

PCB Design

rule = {
  "min_width": [1],
  "min_spacing": [2],
  "clearance": [3]
}

💡 Hint

Common Mistakes

Mixing up spacing and clearance values.

Using values that are too small for manufacturing.

The rule sets minimum trace width to 12 mils, spacing to 8 mils, and clearance to 10 mils for safe PCB design.
