Adding Datasheets to a Component in Altium Designer

Parent page: Working with Managed Components

Altium Designer, in conjunction with your managed content server caters for the ability to store component datasheets within that server and, in doing so, link them to target Component Items. This allows you to more fully describe and support a component, in a centralized fashion, while reducing the reliance on external storage mediums (shared network drives for example). Storing datasheets next to the very items that need to reference them also means you no longer need to have a live internet connection to consult a reference document that can often, and frustratingly, disappear without warning at the whim of the hosting website!

Attaching a Datasheet to a Component Item in the Explorer Panel

For an existing Component Item in a managed content server, one or more datasheets can be attached (uploaded) to that item - essentially creating a link between the component and the datasheet(s) - through the Explorer panel. While browsing the required Component Item, switch to its Data Sheet aspect view tab.

Through the Explorer panel, datasheet management for an existing Component Item is performed from within that item's Data Sheet aspect view tab.

Drag and Drop Attachment

By far the easiest method to attach a datasheet to a component is to select it within your Windows File Explorer, then drag and drop it onto the indicated area of the component's Data Sheet aspect view tab, in the Explorer panel. You can attach any number of datasheets to a component. Once dropped, the file(s) will be uploaded.

Browse for a Datasheet to Attach

Alternatively, you can browse for a datasheet you wish to attach to the component. To do this, right-click within the component's Data Sheet aspect view tab, and choose the Add File command from the context menu. The standard Windows Open dialog will appear, with which to browse to, and open, the required datasheet. After clicking the Open button, the file will be uploaded.

Attach a datasheet to an existing component in the server using the traditional, dialog-based 'browse-and-open' approach.

Post-Attachment Management

Once uploaded and attached to a component, the datasheet will be presented on the Data Sheet aspect view tab in terms of its:

• Caption - this is the user-definable name for the attachment, presented in the Explorer panel, and also in the References sub-menu for a component, after it is placed on a schematic sheet. By default, after initial upload, this will be the filename of the attachment (including extension). Note that the actual filename for the datasheet is not changed in any way.
• File type - the type of file. A file of any format can be attached as a datasheet to the component.
• File size - the size (on disk) of the attached file.

Example datasheets attached to a component, of varying file types.

After attaching a datasheet to a component, all management for that datasheet is performed from within the Data Sheet aspect view tab. This includes being able to quickly open the document by clicking on its entry.

Use the hyperlinked name of the datasheet to quickly access it. In this example a PDF datasheet is opened in the applicable, external PDF Viewer application.

In addition, the following commands are available on the right-click context menu:

• Add File - use this command to attach another datasheet to the component. Once attached, the datasheet is available to all revisions of that Component Item, since it is linked at the item level.

• Edit - use this command to access the Caption dialog, with which to modify the caption for the datasheet (its display name within the software) as required.
• Delete - use this command to effectively remove the datasheet attachment from the component. Only the link between the Component Item and underlying Datasheet Item is deleted. The latter itself is only deleted if no other component is linked to that datasheet.

• Open - use this command to open the datasheet. The attachment will open either within Altium Designer (for example a txt document), or in the applicable external application.
• Save As - use this command to save the attachment to your local media or network drive. Use the standard Windows Save As dialog to determine where, and with what name, the file is saved.

The Datasheet Item

Facilitating the ability to attach a datasheet to a component is the Datasheet Item. When a datasheet is attached to a component, the actual datasheet file is uploaded into a single revision of this item type, and the Component Item linked to that Datasheet Item.

When a new datasheet file is attached to a component, and that file has not already been uploaded (attached to a different component), the resulting Datasheet Item will be created in a Datasheets sub-folder of the active folder.

The mechanics of an uploaded datasheet - the Datasheet Item is linked to the Component Item.

Attaching a Datasheet in the Component Editor

One or more datasheets can also be attached to a component when creating/editing that component through the Component Editor. The following sections take a look at how this is done in both operational modes of the editor.

In Single Component Editing Mode

One or more datasheets can be attached to the active component, while defining that component through the Component Editor in its Single Component Editing mode.

With the new (or existing) single component opened in the temporary Component Editor for direct editing, one or more datasheets can be added in the following ways:

• By dragging and dropping from Windows File Explorer to anywhere within the Parameters region.
• By dragging and dropping a datasheet link from a web page in an external web browser, to anywhere within the Parameters region.
• By clicking the drop-down part of the  button and choosing Datasheet from the associated menu. Use the Open dialog to browse to, and open, the required datasheet(s).

Once uploaded, you can:

• Open a datasheet by clicking on its Value entry in the Parameters region.
• Change the caption for a datasheet, by clicking on its Name entry in the Parameters region and typing the new name as required. Changing a caption for a datasheet is local to that component.
• Remove the datasheet from the component, by selecting its entry in the Parameters region and clicking the  button below the region.

In Batch Component Editing Mode

One or more datasheets can be attached to one or more components, while defining component(s) through the Component Editor in its Batch Component Editing mode. This, for example, allows you to quickly attach the same required dat asheet(s) to all components in a particular family.

Attaching datasheets to a component definition involves a sequence of steps, summarized here and detailed in the sections thereafter:

1. Enabling the use of datasheets.
2. Uploading datasheets to a selected component.
3. Assigning uploaded datasheets to other component definitions.

Accessing a Datasheet from the Placed Component

Once a managed component is placed onto a schematic document within a design project, you can access any datasheets that are linked to it from the right-click References context sub-menu.
