Bonding Pad

Check the rule of Coverlay in FPCB.

Figure 1.

Define FPC components.

1. For Component Group Selection, select FPC components from the component list.
2. For Component Area Definition, select the FPC components’ area boundary.
   You can choose one of component's area boundary among measure (measured Min/Max rectangle area), COC (Component Overlap Check) area, silk, pad and silk pad (silk and pad) region.

Define checking items.

1. Select Coverlay Existence at Reverse Side of FPC Component to check Coverlay data existence on reverse side of FPC component. If there is no Coverlay at reverse side of FPC components, the check fails.

   
   
   Figure 2.

2. Select Pin to Pin Direct Connection Checking to check whether the FPC component’s pins are connected within the component area boundary.

   
   
   Figure 3.

3. Select Minimum Dummy Pad Count to check the number of dummy pads.
   If the calculated dummy pads’ counting number in FPC component is smaller than given value, the check fails.

   • Finding Dummy Pad using Pin Name Filtering: To find dummy pads with name in FPC component, use the string input tool.
   • Check Dummy Pad Count for Edge FPC Component Only: Checking this option, FPC target components will be edge FPC components only.

     
     
     Figure 4.

4. Select Check Overlapping Width between Top and Bottom Coverlays to check the overlapping distance between top and bottom coverlays.
   If measured overlapped distance is smaller than given value, the check fails.

   • Distance between FPC Components and Board Outline along long side of Component: To decide checking sides set the distance between FPC component and board outline. After checking the distance from long side of component to board outline, check for the much distance long side than given value. If two side distances are much longer than given value, check two sides.
