Table 35
In the normal mode, the recognition method is the same as QFP recognition.
Figure 46
QFPs and PLCCs are similar in terms of shape. However, unlike QFPs, the lead tips of
PLCCs may not be stably recognized (because the shape of the leads are not planar).
Also, in some cases, all of the illumination sources (Main light, Coaxal light and Side light)
need to be turned on in order to light up the leads stably. In this case, “Yes” should be
selected from the “All Lighting On” recognition parameter.
If the recognition is still not stable, Lead root recognition mode should be used.
In this mode, the root of the lead is recognized not the tip.
In order to improve the recognition rate, the positional relations between the leads are
checked and the combination best fits the component definition is extracted when the end
leads are detected
When this recognition mode is selected, either “Inside Recognition” or “Inside +
LeadAutoSearch” should be selected for ”Recognition Way” in the recognition parameters.
In the “LeadAutoSearch” mode, Lead detection is performed by using the lead pitch/ lead
width parameter and extracting the data best fits the definition data when detecting the lead
row.
