Layer Sets (for Blind and Buried Vias)

When Blind and Buried vias are used in a design CAM350 must be instructed as to the relationships between the Drill Tables and the layers they are associated with. A Layer Set Table is used for this purpose.


The layer set table is accessed from the Tables/Layer Sets > Blind and Buried pull down menu option.

Click on the Thru Drill button to pop up a Layer List window.


Select the layer associated with the final stage (through) drill using the LMB 
(in this case “CAM_DemoNC1-6.D”).

Set up the table for the fist (blind) layer set as follows:
1. Change the Name entry to reflect the layer set (1-4)


2. Click on a number from the list with the LMB. A Layer List window will pop up. 
     Click on a layer from the list that is to be added in the numbered layer position. 
     In the following example we can see that layers 1 and two have already been selected.    
     Adding CAM_DemoL4.PHO will complete the Blind layer set.

3. The drill data for this layer set is added in the same manner as for the thru drill. 
     Click on the Drill Data button with the LMB to pop up the layer list. 
     Click on the appropriate layer with the LMB to select it .

Set up the table for the second (buried) layer set as follows:
1. Change the Name entry to reflect the layer set (3-4)


2. Click on a number from the list with the LMB. A Layer List window will pop up. 
     Click on a layer from the list that is to be added in the numbered layer position. 
     In the following example we can see that layers 3 has already been selected. 
     Adding CAM_DemoL4.PHO will complete the Buried layer set.

3. The drill data for this layer set is added in the same manner as for the thru drill. 
     Click on the Drill Data button with the LMB to pop up the layer list. 
     Click on the appropriate layer with the LMB to select it .

This completes the Layer Set setup.
