Standard Mark Shapes
and Dimensions
Length and width means the dimensions of the quadrangle circumscribing the
mark.
Mark Materials and
Circuit Pattern
Because PCB recognition correction is based on the positional relationship be-
tween the marks and the circuit pattern (conductor pattern), the marks must be
made in the same process and of the same materials as the circuit pattern from
the viewpoint of correction accuracy.
Image Conditions of
Mark Materials and
PCB Base
Because, basically, mark recognition process is carried out based on the inten-
sity difference of reflected light, a fixed contrast is required between the mark
materials and the PCB base.
This difference varies significantly depending on the plating condition, oxidation
condition, surface height, unevenness, degree of mirroring, coating, or distur-
bance light; therefore, the assessment of the marks is required beforehand.
Mark Dimensions and
Background
The background of a mark requires the noninterference area (larger than fixed
dimensions) outside the mark.
