Placing components on PCB in PCB Design - Cell-by-Cell Formula Trace

Sample Data

This table shows PCB components with their X and Y positions in millimeters and their rotation angles in degrees.

Cell	Value
A1	Component
B1	X Position (mm)
C1	Y Position (mm)
D1	Rotation (deg)
A2	Resistor R1
B2	10
C2	20
D2	0
A3	Capacitor C1
B3	15
C3	25
D3	90
A4	IC U1
B4	30
C4	10
D4	180

Formula Trace

Calculate the distance of each component from origin (0,0) using formula: Distance = SQRT(X Position^2 + Y Position^2)

Step 1: For Resistor R1: SQRT(10^2 + 20^2)

Step 2: For Capacitor C1: SQRT(15^2 + 25^2)

Step 3: For IC U1: SQRT(30^2 + 10^2)

    A          B          C          D
1 Component  X Pos (mm) Y Pos (mm) Rotation
2 R1         10         20         0
3 C1         15         25         90
4 U1         30         10         180

Arrows point from B2,C2 to Distance calculation for R1,
from B3,C3 to Distance calculation for C1,
from B4,C4 to Distance calculation for U1.

The formula uses the X and Y position columns (B and C) for each component row to calculate distance from origin.

    A          B          C          D          E
1 Component  X Pos (mm) Y Pos (mm) Rotation   Distance
2 R1         10         20         0          22.36
3 C1         15         25         90         29.15
4 U1         30         10         180        31.62

The new Distance column (E) shows how far each component is placed from the origin (0,0) on the PCB.
