To know the expected value to enter in the .mod file
To calculate the expected angle between a component and a straight line, you need to
know the orientation of this line in the orthonormal referential (fiducials referencial).
The variable a is the slope of the straight line made by Topo1 and Topo2 in the
orthonormal referential because the line equation is:
Y = aX + b
a =
ρ
is the theoretical angle of the straight line in the .tst file.
ρ
= ARCTAN (a)
• If a > 0
⇒
θ
= T3 -
ρ
• If a < 0
⇒
θ
= T3 +
ρ
The expected angle is different for boards with different orientations in the .tst file.
In the .tst file:
• Board 1 & 3:
T3 = 315°
ρ
= 0°
⇒
θ
= 315°
• Board 2 & 4:
T3 = 135°
ρ
= 0°
⇒
θ
= 135°
