4.5.3 P_pattern explanations
P_pattern diagram explanation
P_pattern 1, 2
Because the lead and body boundary is clearly defined, all four sides of the leads are
checked and the results are used to determine the part positioning.
• Type 1: The leads appear black and the outside circumference is white.
• Type 2: The leads appear white and the outside circumference is black
These are primarily used for parts with bumps.
Example Target Parts
Type 1: White body bumped parts processed with frontlighting.
Type 2: Black body bumped parts or CCGAs processed with frontlighting.

P_pattern 3, 4
The leads extend out from the body of the part and are attached to the body at the base of
the lead. Due to this, the base cannot be checked with a caliper. The lead tips and widths
are checked and the results are used to determine the part positioning.
• Type 3: The lead appears black and the outside circumference is white.
• Type 4: The lead appears white and the outside circumference is black.
These are primarily used for parts with leads on one side or two opposing sides.
With parts that have leads on two perpendicular sides or more, the lead width direction is
only required for determining the positioning, therefore it is recommended to select a
different p_pattern (type: 11, 12, 13, 14) that matches the processing conditions.
Example Target Parts
Type 3: SOP parts processed with backlighting.
Type 4: Black background and body SOP/SOJ parts processed with frontlighting.

P_pattern 5, 6
The leads point towards the inside of the body of the part (opposite from types 3 and 4) and
are attached to the body at the base of the lead. Due to this, the base cannot be checked
with a caliper. The lead tips and widths are checked and the results are used to determine
the part positioning.
• Type 5: The lead appears black and the outside circumference is white.
• Type 6: The lead appears white and the outside circumference is black.
These are primarily used for parts with leads on one side or two opposing sides.
With parts that have leads on two perpendicular sides or more, the lead width direction is
only required for determining the positioning, therefore it is recommended to select a
different p_pattern (type: 11, 12, 15, 16) that matches the processing conditions.
Example Target Parts
Type 5: PLCC socket parts processed with backlighting.
Type 6: Parts with leads pointing towards inside of the body and has a black background
and body and is processed with frontlighting.
