Board outline and dimensions in PCB Design - Cell-by-Cell Formula Trace

Sample Data

This data represents the dimensions of a PCB board: length, width, and margin for outline.

Cell	Value
A1	Length (mm)
B1	Width (mm)
A2	100
B2	50
A3	Margin (mm)
B3	5

Formula Trace

= (A2 + 2 * B3) * (B2 + 2 * B3)

Step 1: 2 * B3

Step 2: A2 + 2 * B3

Step 3: B2 + 2 * B3

Step 4: (A2 + 2 * B3) * (B2 + 2 * B3)

References:
- A2 (Length)
- B2 (Width)
- B3 (Margin)

The formula uses Length (A2), Width (B2), and Margin (B3) to calculate the total board area including margins.

Result

     A      B       C
  +-------+-------+---------+
1 |Length | Width |  Area   |
  +-------+-------+---------+
2 |  100  |  50   |  6600   |
  +-------+-------+---------+
3 |Margin |   5   |         |
  +-------+-------+---------+

The final result in cell C2 shows the total board area including margins: 6600 mm².

What is the value of 2 * Margin (B3) in the formula?

A 5

B 10

C 15

D 20

Key Result

Calculate total board area by adding twice the margin to length and width, then multiply.
