What istape automated bonding

Tape Automated Bonding (TAB) is a modern and efficient bonding method used in the electronics industry. This process involves bonding bare chips to a polyimide sheet which is then placed on a Printed Circuit Board (PCB). The tape is then cut and the leads are soldered to the board. This process minimizes the space required by the chip and is more cost-effective than traditional bonding methods.

The bonded assembly is then “glob topped” with epoxy or plastic, thereby enclosing the bare chip. The result is known as a “tape carrier package” (TCP), which is a compact, lightweight, and reliable packaging solution for a variety of electronic devices.

Advantages of Tape Automated Bonding (TAB)

  • Reduced size and weight: Since the tape carrier package is compact, it requires less space on the PCB, thus reducing the overall size and weight of the device.
  • Improved reliability: The encapsulation of the bare chips in the tape carrier package provides better protection against harsh environments, such as high temperature and humidity, which can cause failure in electronic devices.
  • Cost-effective: The TAB process is less expensive than conventional bonding methods as it requires fewer components and utilizes less space on the PCB.
  • Efficient production: The TAB process is fully automated, enabling high volume production with minimal human intervention.
