Technical Cleanliness Tutorial

PollEx Technical Cleanliness (TC) is an optional module of the PollEx PCB and a reliability analyzing tool set for PCB designs.

PollEx TC checks for visible residues called particles to decreases short-term and long-term board problems and increase functionality. The Checked results of PollEx TC can be exported into a well formatted Excel spreadsheet. As a result, PollEx TC helps to reduce defectiveness and increase productivity.

  1. Launch PollEx PCB.
  2. Open the PollEx PCB layout design file.
    1. From the menu bar, click File > Open.
    2. Navigate to the PollEx_New_Sample.pdbb file located at C:\Temp\Altair-PollEx\PollExTechnicalCleanliness.
    Refer to the PollEx PCB manual to use the PollEx PCB viewer.
  3. Execute Technical Cleanliness Input.
    1. Click Option > Technical Cleanliness > Input.
    2. Click Load and select the TC_Input.teci file located at C:\Temp\Altair-PollEx\PollExTechnicalCleanliness\TCI.
    3. Click Start to run the Analysis.
      PollEx TC checks where the design’s data input rules and constraints apply.
  4. Check the results.
    The test results are displayed on the screen (Particle size & locations).
