Basically, these are the same as p_pattern types 3 and 4. The major difference is that with these p_patterns, the outward pointing lead tip is not used for determining the part positioning. The lead width detection results only are used to determine the part positioning. The lead tip detection results are used only as reference data for internal vision processing items.
Type 13: The lead appears black and the outside circumference is white.
Type 14: The lead appears white and the outside circumference is black.
It is only possible to use this for parts that have leads that are to be detected on two perpendicular sides or more.
Furthermore, the information for the part positioning using the lead length is not acquired so these types cannot be used for parts with leads on one side or two opposing sides only.
Example Target Parts
Type 13: QFP parts processed with backlighting.
Type 14: Black background and body parts (e.g., QFP) processed with frontlighting.
