Introduction

The plugin Component Analysis can be found under the grid "Analysis" respectively "Assembly".

Here you will find two tab pages available for performing the Component Analysis: "Component Distance Analysis" and "Component Placement Analysis". These single analysis functions are described below.

Component Distance Analysis

The "Component Distance Analysis" option allows you to check the distance between components and between components and the board outline. This analysis is important to ensure e.g. the manufacturability during the placement and soldering process.

In the first block (1) you can define the different check values:

  • "Outline to Outline": Min. needed distance between component bodies
  • "Pad to Outline": Min. needed distance between the copper pads of one component to the body of the neighbour components
  • "Pad to Pad": Min. needed distance between the copper pads of one component to the copper pads of the neighbour components
  • "Outline to Board Outline": Min. needed distance between component bodies and the board outline

Here you also have the possibility, to ignore unplaced components (by ignoring components with a ".comp_ignore' attribute).

In the second block (2), you can define "Special Distances acc. Property". That means, you can define the same set of rules as in (1) but with different values for sub groups of components. The sub groups are build by a given component property. Examples are:

  • if your design has a property with package groups per component, you can set different check values for e.g. SOTs or ICs
  • if your design has a property with detailed component descriptions, you can set different check values for e.g. ceramic capacitors or mosfets

The results of the analysis are displayed in the window on the bottom (3). You can also view the analysis results directly in the tool. Critical errors can also be marked for later use (e.g. in the 'Extended Design Report').

With the buttons on the top right side of the window you can export the previously defined settings so that you can reuse them for later analyses. Already saved settings can be imported via the "Import Settings" button. 

The last result can be saved and reloaded with the buttons on the lower left side (4). This stored result is also used in the 'Extended Design Report'.

Clicking on the question mark on the top right of the window opens the corresponding page of our online manual.

The copper pad of the X1-1 is too close the the component body of C36.

 

Component Placement Analysis

The "Component Placement Analysis" option allows you to check, if the MPN Package of a component fits the CAD Package.
A MPN Package (MPN = Material Part Number) is the real component outline of a part. This outline is often much smaller than the corresponding CAD package body. The MPN Package can also contain the contact surface of the pin. In this analysis, this contact surface of the pins is analyzed. You can define, where the contact surface has to be situated inside the copper pad.

A standard design has no MPN Package definitions included. EasyLogix offers the 'EasyLogix Part Library' (EPL) to add detailed part information like datasheets, MPN packages, 3D step files, ... to your design.

In the first block (1), you can define the different check values:

  • "Outer Distance": The minimum distance of the pins contact surface to the outer edge of the copper pad in % of the pad's width
  • "Inner Distance": The minimum distance of the pins contact surface to the inner edge of the copper pad in % of the pad's width
  • "Side Distance": The minimum distance of the pins contact surface to the side edges of the copper pad in % of the pad's height
  • "Center Distance": The minimum distance of the pins contact surface to all edges of the copper pad in % of the pad's min. size - only for pins that are located under its component body

In the second block (2), you can define filters to ignore unplaced components (by ignoring components with a ".comp_ignore' attribute) and components without MPN package definitions.

In the third block (3), you can define "Special Distances acc. Property". That means, you can define the same set of rules as in (1) but with different values for sub groups of components. The sub groups are build by a given component property. Examples are:

  • if your design has a property with package groups per component, you can set different check values for e.g. SOTs or ICs
  • if your design has a property with detailed component descriptions, you can set different check values for e.g. ceramic capacitors or mosfets

The results of the analysis are displayed in the window on the bottom (4). You can also view the analysis results directly in the tool. Critical errors can also be marked for later use (e.g. in the 'Extended Design Report').

With the buttons on the top right side of the window you can export the previously defined settings so that you can reuse them for later analyses. Already saved settings can be imported via the "Import Settings" button. 

The last result can be saved and reloaded with the buttons on the lower left side (5). This stored result is also used in the 'Extended Design Report'.

Clicking on the question mark on the top right of the window opens the corresponding page of our online manual.


Following picture shows an example error of this analysis:

The contact surface of the pin 2 of the MPN Package for D30 is not matching the "inner distance" rule. That means in this case, the pin's contact surface is partly outside the copper pad. A reason could be, that the choosen part (MPN) does not fit to the CAD data. Soldering issues and failures are likely.

 

OIB Server Manager

When you open the "SIPLACE OIB Connector" (in the 'Machine Export' menu) the first time, you have to first enter your OIB server settings by clicking on the gear button (1)


Following dialog will open:

In this server manager, you can organize multiple OIB servers. To create a new one, please press on the little green "+" button and enter a name.
Afterwards you'll have to specify the OIB server adress by entering an IP/Hostname + Port, or directly enter the 'net.tcp://...' adress (1).

When this is done, you'll have to specify two server directories by clicking on the small browse button (2):

  • "Component Main Path": This is the OIB directory, where your part library is located. Parts in this directory are only read, but never written or changed.
  • "Component User Path": This is the OIB directory, where parts, that do not exist in the main path yet, are created by PCB-Investigator. The user has to complete the information of those parts in the SIPLACE Software and can then move them to the main path later.

Click "Save" and close the dialog to preceeed.

Placement List Creator

To start, please select a server and click "Connect" (1).

With the "Placement List Creator" tab, you can create placement list elements for each component side on the OIB server.


To start, you have to do a few settings in block (2):

  • 'Current Step': Select the board step, for which placement lists should be created
  • 'Group Components by': Choose whether to use the internal 'Part Number' or any other Property in your CAD data to get the list of part numbers. These part numbers are the 'key' to search for parts on the OIB server.
  • 'Component Type Filter': You can filter components by the '.comp_mount_type' attribute, e.g. to get only SMT components

Always when you change settings in (2), you will have to 'Refresh' the list and 'Match Parts via OIB' again (3).

When the matching process is done, you will see all your filtered parts in the list (4), including an overlay of the matching OIB part definition on the selected server. Found OIB parts are centered on the CAD package center. Details of the found OIB part and the fitting state are listed on the bottom side (5).
The 'Status' column indicates, whether a OIB part was found or not, and if the found part fits onto the CAD package. The condition for fitting is, that the pin definition of the OIB part must at least partly overlap the CAD package pin.

If the found part does not fit, you have the possibility to shift its position or to rotate it until it fits (6). With the two buttons in this block on the right, you can open the property dialog of the CAD component or zoom to it.

If the OIB part has a polarity definition, this polarity marker is visualized in red. The fitting alorithm then also uses the polarity information, to recognize if the component is correctly rotated (CAD polarity pin is same as OIB polarity pin).

Example of the fitting process (6) (by rotating 90° clockwise):

When clicking the 'Create Placement List via OIB' button (7), you are asked to select a folder on the OIB server and enter the name for the placement list(s) for top and/or bottom side. Afterwards, the placement lists are created via OIB. Missing parts, that where not found during the matching process, are automatically created in the 'Component User Path' (see 'OIB Server Manager'). Those created parts are dummy parts without any real outlines or pin definitions. Their information must be completed by the user in the SIPLACE Software afterwards. Components that have the ".comp_ignore" attribute are marked as 'omitted' in the placement list.

Here is a screenshot of the result in the SIPLACE Software:

Board Creator

After having created the placement list of the single board(s), you can create the panel data with the "Board Creator" tab.


To start, you have to select the panel step that should be created (1). It is also possible to create panels in panels (recursive), when the most outer panel is selected.

For the given panel, the included single board(s) is/are listed unter (2). Here an already existing placement list on the OIB server must be selected per board and side. If the placement lists where created before in this session with the "Placement List Creator", the information is already prefilled. If not, you can click the small browse button and select the right placement list.

In the block (3), there are different options available:

  • "Export Board Outline": if checked, the complex board outline of the CAD data is exported. This may need some time. If not checked, the bounding box is used
  • "Export Fiducials": if you want to export objects with ".pad_usage=gfiducial/lfiducial", please check this box and select a fiducial type from the OIB server by clicking on the little browse button
  • "Export Inkspots": if you want to export objects with ".board_mark=bbm" (Bad Board Marker), please check this box and select a fiducial type from the OIB server by clicking on the little browse button
  • "Requires trace information": This field on the OIB server can be set or not here
  • "Requires PCB barcode verification": This field on the OIB server can be set or not here
  • "Default processing orientation": 0/90/180/270° for Top or Bot (sets the corresponding fields on the OIB server)

In the block (4), you can choose which CAD layers should be exported and imported in OIB for this board per side. It is mainly thought for paste/mask layers.

When clicking the 'Create Board via OIB' button (5), you are asked to select a folder on the OIB server and enter the name for the board entry. Afterwards, the board is created via OIB.

Here is a screenshot of the result in the SIPLACE Software:

 

 

SIPLACE QD Exporter

With the "SIPLACE QD Exporter" tool, you can create '.qd' files including placement lists and board information for ASM machines.


To start, you have to do a few settings in block (1):

  • 'Current Step': Select the board or panel step, that should be exported
  • 'Group Components by': Choose whether to use the internal 'Part Number' or any other Property in your CAD data to get the list of part numbers. These part numbers are the 'key' to search for parts in SIPLACE.
  • 'Component Type Filter': You can filter components by the '.comp_mount_type' attribute, e.g. to get only SMT components

Always when you change settings in (1), you will have to click at 'Refresh' to update the list. In the list (2), you will see all packages and the corresponding parts for each step or sub-step of your selected (panel) step.

It is then important so select list entry by list entry to check the rotation correction. If a entry is selected, you'll see the package drawing on the right side. You have to rotate this package to be displayed in exactly the same way, as it is defined on the ASM machine ('make it ASM conform'). You can confirm this by checking the "User Confirmed" checkbox in the list's last column. The rotation can be done by using the buttons in (3). Here, the rotation can also be reset and with the two buttons in this block on the right, you can open the property dialog of the CAD component or zoom to it.

In the block (4), you can choose which CAD layers should be exported as gerber files next to the '.qd' file. These gerbers can then be also imported in SIPLACE. The mirroring/translation of the bottom gerber is already done in the gerber itself, so that you do not need to transform the layers in SIPLACE.

In the block (5), there are different options available:

  • "Export Fiducials": if you want to export objects with ".pad_usage=gfiducial/lfiducial", please check this box and enter the fiducial path/name that is defined in SIPLACE.
  • "PCB Height": here you can enter the height of the PCB in the given unit.
  • "Project name": this name of your project, will be exported also to the '.qd' file
  • "Export Top Side": if checked, you'll get a '.qd' file for the top side of your PCB
  • "Export Bottom Side": if checked, you'll get a '.qd' file for the bottom side of your PCB

When clicking the 'Export QD File(s)' button (6), you are asked to select a folder where the files are exported to.
