Package and Assembly Technologies

Package and assembly technologies form the critical bridge between the microscopic world of integrated circuit fabrication and the practical reality of electronic systems. While semiconductor manufacturing creates intricate circuits on silicon wafers, packaging transforms these delicate structures into robust components that can be mounted on printed circuit boards, connected to power and signals, and protected from environmental hazards throughout decades of reliable operation.

The evolution of IC packaging has kept pace with the relentless advancement of semiconductor technology, progressing from simple wire-bonded packages with a handful of leads to sophisticated three-dimensional structures containing multiple dies with thousands of interconnections. Modern packaging technologies address not only the challenge of providing electrical connections but also managing heat dissipation, ensuring signal integrity at gigahertz frequencies, and enabling the heterogeneous integration of diverse technologies into compact, high-performance systems.

This section groups the field into four related areas. It begins with the established package formats that house individual dies, continues through the board-level processes that assemble those packages onto circuit boards, examines the design trade-offs that govern package performance and reliability, and concludes with the advanced techniques that combine multiple dies into a single high-bandwidth system.
