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.
