Speedstack material library requirements
Application Note AP536 

Importing material to the Speedstack materials library

Speedstack allows users to add existing material lists to its library; material data must be arranged in the format and order used by the Speedstack library.

Library materials can be imported from local library files or from the Polar Online Library.

Importing from the Polar Online Library

Choose the material table tab (Foils, Prepregs, etc.) and click the Online Library icon.

Choosing the online library

Speedstack connects to the Online Library and displays the materials available for each type, grouped by supplier.

Displaying materials

Browse throught the list of available materials or scroll through the list of suppliers and choose a supplier to filter the materials by that supplier.

Filtering libraries by supplier

To view just the materials available from one supplier click on the material supplier’s logo in the Filter by Supplier pane.

Choosing libraries by supplier

Filtering libraries by frequency

Material libraries contain values for dielectric constant (Dk) and loss tangent (Df) measured at frequencies specified by the supplier. The measurement frequency is indicated in the library file name.

Use the Filter by Frequency function to list all files or just the files with Dk and Df specified at the selected frequency.

Choosing libraries by frequency

Choose the material library and click Clear to replace the current single library with the new materials or Append to add the materials to the existing library data table and when downloading multiple libraries during a single session.

Choose the File Type and material. From the Existing Data Table dialog select Clear to replace the contents of the selected table or Append to add the new materials to the table.

Clearing or appending to the library

Click Download; repeat for each material to be added to the library then click Close.

Importing from local material files

Prior to importing the material data file ensure the file is not open in another process (e.g. Microsoft Excel.)

Click the Speedstack Materials Library button to open the Library, and then click Import CSV Library to open the Import dialog.

Import CSV

When importing materials set the Import options in the Import dialog:specify the units, delimiter and material type and specify whether the materials will be used to clear the current data tables or append to the existing library.

Import options

Replacing existing material tables

Choose the Clear Existing Data Table option and choose the field delimiter type. The library import function can accept files in a variety of formats, tab delimited, comma separated and Excel worksheet and template formats but must be in the format of the supplied sample files with columns in the correct order.

Specify the units for import, file delimiter and choose the file type (Foil, RCC, Prepreg, etc.) and click Import. Navigate to the file via the Open dialog and click Open.

Repeat the procedure for every file type to be imported. Save the file as a .mlbx library file.

Adding material data to an existing library

To add material data to an existing library table, open the library, click Import CSV Library, click the Append to Existing Data Table and click Import.

Navigate to the .csv or .txt file and click Open. Save the modified library file as a .mlbx file.

Exit the library when all file types have been imported.
