Tech Product Teardowns

  About 
  The PennEngineering® teardown process involves the careful documented disassembly of a current consumer product. All     products chosen for teardown are purchased through publicly accessible channels. Teardowns are performed by   PennEngineering technical personnel for the purpose of understanding current assembly trends and to identify possible   improvements using PennEngineering® fastener types or other methods. Observations, comments and recommendations are   based on the opinion of the technical expert conducting the teardown.

  In this brief video, our engineer presents such examples where certain current fastening solutions could be improved with the   use of TackSert® Pins, Snap-in™ Fasteers, or the TackSert® style Micro Button.
