Step 1:

Find which code relates to your ribbon width and thickness.

For example, 0.002” width and 0.0005” thickness gives you A1.

This gives you your slot size in your wedge.

Step 2:

Once you have the code, cross reference it to the wedge model table.

You will need to have an idea of what bond length is necessary for the application.

Using the example from above – A1 – you can see there are two choices to select.

A120 – 0.002” x 0.0005” Slot Size – 0.020” BL

A125 – 0.002” x 0.0005” Slot Size – 0.025” BL

Step 3:

Once you have your four digit code for the ribbon (A120 for example), the specification of the wedge tool then has to be defined.

This includes features such as the Wire Feed Angle, Shank Style, Surface Finish, Wedge Length, etc.

These can all be found in the chart above and within wedge catalogues.

Below are some dimension drawings which explain in more detail what the key features of a wedge are.
