Note 1: The lead pitch less than 0.4 mm is optional. When the lead pitch is less than 0.4 mm, the
dimensions of a component should be 24 mm x 24 mm or less (for a 27-mm VCS).
Note 2: The recognition precision of a component whose number of leads is less than four cannot be
guaranteed.
Note 3: When image of a component is divided into two for recognition, the minimum number of
leads is 14. When it is divided into three, the minimum number of leads is 21.
Note 4: The machine cannot recognize divided images of a PLCC (GFJ) or SOJ component for
recognition.
Note 5: Only the standard VCS can divide and recognize image of a connector.
Note 6: The machine cannot recognize divided images of an aluminum electrolytic capacitor. Only
the standard VCS can recognize this type of component.
Note 7: For this component, enter the number of missing leads on a heat sink.
