Board Drill Checks

Board Drill Checks

Board Drill Checks

Board Drill Checks analyzes drill hole spacings in board layers and creates a report to list all the findings
Checks spacings for both drill and rout holes in the same layer
Board Drill Checks only provide analysis check, does not change layout content
Prerequisite：
- Drill attribute .drill must be assigned to drill holes, to distinguish PTH/NPTH/Via holes
- Drill and rout layer must be defined in the matrix

Open Board Drill Checks

In the Graphic Editor screen, select "Analysis" ，then select "Board Drill Checks" 。( Command ：chklist_single )

Parameters

Parameters values can be changed in the respective fields and saved in ERF
All values and settings shown in this guide is by default
Parameters interface are shown below ：

Parameters：

Operation-Modes

Set spacing analysis target
- Single ：check spacing for features on the same layer
- Cross ：check spacing for features across layers

Check

Set multi layer analysis mode:
- Board ：analyze all board layers with drill holes
- Affected ：analyze affected layers only

Layer

Select drill layer to run analysis

First-Element-Type (Row 1)

Include Via holes in the analysis (drill hole with .drill=via attribute)

Second-Element-Type (Row 1)

Check to analysis spacing between Via holes and Via / PTH / NPTH / Rout

First-Element-Type (Row 2)

Include PTH holes in the analysis, (drill holes without .drill attribute，or with .drill=plated )

Second-Element-Type (Row 2)

Check to analysis spacing between PTH holes and PTH / NPTH / Rout holes

First-Element-Type (Row 3)

Include NPTH holes in the analysis (drill hole with .drill=non_pated attribute)

Second-Element-Type (Row 3)

Check to analysis spacing between NPTH holes and NPTH / Rout / Rout %
Rout % value: distance/radius*100

Use Compensated Rout

Choose methods to analysis rout
- Yes:Use compensated rout for analysis
- No:Use original rout for analysis
- Skeleton:use rout skeleton for analysis

Set Range

Command ：chklist erf range

Set range value for each analysis check items
There are three types of analysis result: Critical, Warning or Safe
Default setting is avaialble for all parameters
Value can be changed in respective fields, and saved in ERF
See below picture for the Range interface：

Range items：

Via to Via

Analyze Via to Via spacing

Via to PTH

Analyze Via to PTH spacing

Via to NPTH

Analyze Via to NPTH spacing

Via to Rout

Analyze Via to rout spacing

PTH to PTH

Analyze PTH to PTH spacing

PTH to NPTH

Analyze PTH to NPTH spacing

PTH to Rout

Analyze PTH to rout spacing

NPTH to NPTH

Analyze NPTH to NPTH spacing

NPTH to Rout

Analyze NPTH to rout spacing

NPTH to Rout_%

Analyze NPTH to Rout_% spacing
- Rout % value: distance/radius*100

Run Board Drill Checks

Run Board Drill Checks (Command：chklist_run)
Three buttons in the lower interface, each button runs the module at different area range
- Global ：Analyze all features in the layer ( Command：chklist_cupd )
- Screen ：Analyze all features in the screen display area( Command：chklist_cupd )
- Profile ：Analyze all features in profile frame( Command：chklist_cupd )

View Analysis Report

Click the " ＋ " button on the lower right to view analysis report ( Command：chklist_ res_show )

Result Viewer Form will be opened after click on the " ＋ " button

Result Viewer Form

In Result Viewer Form, Severity report will be displayed based on selected layers

View Detected Error in the Layout

In Result Viewer Form, click " <-- " or " --> " to view each error entry in the layout (See example below)

Click "Show All" will highlight all the error spots in the layout(See example below)

View Result Histogram for Analysis

Select an error entry, click the bar icon on lower right to open Result Histogram

Command ：chklist_ hist_close

Command ：chklist_ hist_show
