Guide Hole
Validate the guiding hole in the PCB's design.
The Guide Hole dialog contains the following sections:
- Board Direction Definition: Decide the board's placement status using the
soldering mark or by defining the soldering direction.
- Soldering-Mark Component Group: Define the soldering mark. Use if it is registered as a group of components.
- Mark Direction: Define the mark’s direction and the soldering direction.
- Soldering Direction: Define the direction of the board without using soldering-mark case.
- Guide Hole Definition: Define the target guiding hole to analyze.
- Component Group Selection: Select the component group from Component group list. Use if a component is used as a guiding hole.
- Padstack String: Define the via using string filter. Use if a padstack is used as a guiding hole.
- Via (NPTH): Set the via from the via list. Use if a via is used as a guiding hole.
- Board Figure Geometries: Define the hole length and diameter. Use if board figure geometries are used as a guide hole.
- Guide Hole Searching Ranges from Board Corner: Set the area where the guiding hole is located. Specify area values with dX and dY from the board corners. Refer to Figure 4.
- Circle Type Guide Hole Checking
- Circle Guide Hole Counting: Verify the number of circle type guide
holes at specified regions.
- Number of Total Guide Hole: Verify the number of guide holes.
- Counting: Verify the number of guide holes in the upper and lower side of the PCB.
- Diagonal Counting: Verify the number of guide holes in the
diagonal sides.
- Left Top, Right Bottom: Set the number of guide holes in these regions.
- Right Top, Left Bottom: Set the number of guide holes in these regions.
- Circle Type Guide Hole Location: Verify the guide holes in each board corner. The table rows each correspond with the four corners of the PCB.
- Circle Guide Hole Counting: Verify the number of circle type guide
holes at specified regions.
- Center Guide Hole Checking
- Major Axis Existence: Verify the center guide hole is on the major axis of the board.
- Minor Axis Existence: Verify the center guide hole is on the minor axis of the board.
- Tolerance: Input the tolerance value from the center of the boards major or minor axis.
- Check Single Guide Hole: Verify there is only one center guide hole.
- Ellipse Type Guide Hole Checking
- Ellipse Guide Hole Counting: Verify the number of ellipse type guide
holes at specified regions.
- Number of Total Guide Hole: Verify the number of guide holes.
- Counting: Verify the number of guide holes for the upper and lower side of the PCB.
- Diagonal Counting: Verify the number of guide holes at the
diagonal sides of the PCB.
- Left Top, Right Bottom: Set the number of guide holes in these regions.
- Right Top, Left Bottom: Set the number of guide holes in these regions.
- Ellipse Type Guide Hole Location: Verify there are guide holes in each corner. The table rows each correspond with the four corners of the PCB.
- Ellipse Guide Hole Counting: Verify the number of ellipse type guide
holes at specified regions.
- Clearance between Guide Hole and Components
- Clearance Table: Set and assign a clearance value for the component group. Use PollEx DFM to verify the clearance between the component outline and the guide hole edge.
- Remainder: Assign a clearance value for the undefined components in the table.
- Checking the location of Guide Hole, matching with Board Origin:
- Guide Hole Selection: Select the target corner of the board.
- Clearance between Guide Hole and Board Outline: Set the clearance value between the guide hole and the selected board corner.
- Clearance Checking:
- Include Checking for Center Guide Holes: Verify the inclusion of the center guide hole selected in the Center Guide Hole Checking is necessary.
- Clearance to Route Pattern: Verify the clearance between the guide hole and route pattern.
