Error Proofing for Integrated Circuit Chips Loaded in Pocket Tape

Join the strengths of the Q4X and iVu vision sensor for a triple inspection of IC Chips

Integrated circuit (IC) chips are tested before installation onto a circuit board. After they pass quality tests, they are placed into a pocket tape and spooled onto a reel. The tape and reel make transport and storage for such small components easy and simplify the way that the product is fed into assembly machines.

Each IC chip is placed onto the pocket tape by a high-speed machine. Incorrectly oriented chips will result in improper installation onto a circuit board. There are three common failure modes with pocket tape: no chip in the pocket, two chips in the pocket, and one chip upside down in the pocket. To prevent these errors, each chip’s presence and orientation needs to be confirmed before it is sealed in the pocket tape. Multiple sensors are often used to identify these failures. Supporting multiple sensors can drive up expenses and lead to increased downtime required for maintenance and installation.

Your Benefits

  • More thorough detection of errors before installation on circuit boards
  • Confirmation of writing orientation on IC chips
  • Reduced cost using fewer sensors to solve the application
