SMD Summary

• + SMD Summary analyzes SMD pad on outer layers, creates report on SMD land and packages

Open SMD Summary

• In Graphic Editor screen, select "Analysis" ，then select "SMD Summary" 。( 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

Layer

• Select layer to run analysis

Pad size min

Set minimum size for SMD pad

Stagger

Set minimum spacing for SMD pitch

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

SMD Row

• Set analysis result range for SMD rows, a row is formed by three or more SMD pad with the same spacing

SMD Pack

• Set analysis result range for SMD pack, a SMD pack is formed by two matching rows, if two SMD pack shares the same center point, it can be considered as the same pack

Pad Too Small

• Set analysis result range for detecting SMD size and pitch, reference value in Pad size min and Stagger

Needs Staggering

• Set analysis result range for pad average pitch in SMD pack, reference value in Stagger and detect pads that need staggering

Pitch Is Non-Uniform

• Set analysis result range for SMD pad with pitch distance lower than average, based on value from Max SMD ununiformity ，SMD pack with uneven pitch will be detected.

Picture Frames

• Set analysis result range for detecting pad from SMD pack to be covered by solder mask of the same net

In Pitch SMDs

• Set analysis result range for detecting SMD pad pitch is same as average pitch in SMD pack, based on value from Max SMD ununiformity

Off Pitch SMDs

• Set analysis result range for detecting SMD pad pitch is not the same as average pitch in SMD pack, based on value from Max SMD ununiformity

PITCHxSIZE_ARx<pitch_value>x<size_value>

• Set analysis result range for detecting SMD pad annular ring, based on pitch and pad size and arranged by pitch value

PITCHxSIZE_STRIPEx<pitch_value>x<size_value>

• Set analysis result range for detecting spacing between SMD pad and solder mask pad , based on pitch and pad size and arranged by pitch value

SIZExPITCH_ARx<size_value>x<pitch_value>

• Set analysis result range for detecting SMD pad annular ring, based on pitch and pad size and arranged by size value

SIZExPITCH_STRIPEx<size_value>x<pitch_value>

• Set analysis result range for detecting spacing between SMD pad and solder mask pad , based on pitch and pad size and arranged by size value

Set Advance Variables

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

Max SMD size

Set maximum size for SMD pad, pad with size over this value will be excluded from analysis

Rounding value applied to results

Set rounding value for analysis items, this setting will be applied to PITCHxSIZE_STRIPE 、 PITCHxSIZE_AR 、 SIZExPITCH_STRIPE 、 SIZExPITCH_AR

Max SMD ununiformity

Set tolerance value for pitch distance, if any pitch in a SMD pack has higher value, the pack will be considered as uneven

Sort by pitch

Set the order of analysis item, use PITCHxSIZE_STRIPE 、 PITCHxSIZE_AR to arrange by pitch value, use SIZExPITCH_STRIPE 、 SIZExPITCH_AR to arrange by size value

Run SMD Summary
