The Angle Resolution section in the Machine List window (in the Process Definition window) gives you a way to verify each unique shape/package’s fit on the board and confirm its angle orientation, relieving the need to physically place components on a board with double sided tape. This method allows the validation and correction of placement angles that will be exported in the generated machine program and minimizes the adjustments necessary to begin running the board in production.

Basic Steps for using the Machine Angle Correction Center

The high-level steps for validating and/or correcting machine placement angles are shown below; read through to the end of this topic to learn about the different options you can select in the Machine Angle Correction Center to help you complete this task quickly.

1. Select the Calculate All Angles button

2. Select the first part in the list and visually confirm that the correct shape has been chosen and the rotation is suitable (when comparing the overlay to the CAD shape) and either confirm it or correct it.

3. Advance through the list until all package types are confirmed.

Check and validate machine placement angles

Use the Machine Angle Correction Center options to check and validate correct all machine placement angles automatically or on a part-by-part basis. The Angle Resolution options are used with certain advanced machine types to validate or correct machine placement angles (theta) specific to that machine type:

• Blue indicates unconfirmed angles

• Green indicates confirmed angles

• Red indicates parts with angle errors.
  
  

Open

Settings - The Settings button (the gear) in the upper-right corner of the window displays check boxes where you can specify the items that will be displayed and how angles are confirmed.

• Show Confirmed Shapes - Displays confirmed parts (Green).

• Show Unconfirmed Shapes - Displays unconfirmed parts (Blue).

• Advance on Confirm - Advances to the next part in the Part Number list when an item is confirmed.

• Confirm All on Recalculate All - All parts will be confirmed automatically when you select Recalculate All.

• Show Angles in Clockwise Convention - Displays angles using the Clockwise convention.

• Show Negative (270 is -90) - Specifies that 270 degrees is equivalent to -90 degrees.

Validate all machine placement angles automatically

To check and validate all machine placement angles automatically, you use the buttons on the left side of the Machine Angle Correction Center:

Calculate All Angles - Automatically calculates placement angles for all parts.

Reset All - Resets all placement angles to their original settings (select Yes to reset all angles when the prompt displays).

Offset Overlays - Slightly offsets the machine package overlays in the X and Y direction in the event they are obscuring the underlying CAD footprint. (If you change your mind, select the button again to undo the offset).

Confirm All Angles - Confirms all placement angles as they are (select Yes to confirm all angles when the prompt displays).

1. Select the Calculate All Angles  button. (Calculate All Angles uses internal angles convection logic as supplied by the machine manufacturer to calculate the angle required by the machine based on the ECAD rotations.)

2. Select the Confirm All Angles button. 
   
   

Validate machine placement angles for selected parts

1. To check and validate machine placement angles on a part-by-part basis, select a part under Part Number in the Machine Angle Correction Center.

2. Step through each part number in the Part Number list (use the Previous and Next buttons) and confirm the rotations or adjust the angles and then confirm the angles.

3. Make any necessary changes, then select the Confirm button for each part number.

4. Use these buttons to help you confirm machine placement angle settings for a selected part in the Part Number list:
