4.7.1 Background Existing Fuji machines support both backlight and frontlight systems, however, the newly developed NXT machines support frontlight only. As a result, it is necessary to convert existing part data created for used with a backlight system to enable the part to be processed using a frontlight system. The NXT machines are equipped with […]

Case 4 for 4.6.3 Selecting A Vision Type Flowcharts (Leaded Parts) of Part Data Settings Figure 2: Example of left to right symmetrical part and Top to bottom symmetrical part Detemine the symmetry by considering all white items that can be seen (lead or other metal items). Figure 3: Examples of asymmetrical parts Detemine the […]

Case 3 for 4.6.3 Selecting A Vision Type Flowcharts (Leaded Parts) of Part Data Settings Figure 1: Example of rectangular shaped leads and Example of non-rectangular shaped lead The defined lead area and actual captured image is substantially different, distinguish by the rectangular and non-rectangular lead shapes. For example, if the center thinner leadwidth is […]

Case 2 for 4.6.3 Selecting A Vision Type Flowcharts (Leaded Parts) of Part Data Settings Figure 4 Parts That Have Leads In The White Body Area. Figure 5 Used The Parts From #4. Used Vpdplus And Set The Lighting To “Incident” And Exposure Time To “170MS”. Figure 6 Poor Lead Shape (The Leads Are Too […]

Case 1: Entire body color is black or a dark color (black, blue, green or yellow green) Figure 1: Example of rectangular shaped leads Example of non-rectangular shaped lead The defined lead area and actual captured image is substantially different, distinguish by the rectangular and non-rectangular lead shapes. For example, if the center thinner leadwidth […]

This vision type is used for those parts with a white or gold colored body, and processes only the part outline. It is necessary to enter the body size in part data. The body size should be measured from edge to edge. Positioning is performed using the outer-most points on the upper and lower, and […]

Enter the part body size and element information in part data. Vision types 230, 231, 233, and 234 use the body center while vision types 235, 236, 237, and 238 use the part center. Due to the use of frontlighting, there are cases where the image of the ball grid may vary depending on the […]

Use this vision type for coil parts with 2 leads that are at 45 degree angles from the x-axis (as shown below). The body color is black and only the leads are visible during vision processing. Enter the body size and element information in part data based on the information below.

Use this vision type for parts with between 2 and 6 leads where the body color is black and only the leads are visible during vision processing. Enter the body size and element information in part data. Vision type 180 uses the body center while vision type 185 uses the part center Note: This vision […]
