A
copper pillar assembly is a type of interconnect used in the manufacture of electronic devices, such as integrated circuits (ICs) and printed circuit boards (PCBs). It consists of a copper pillar, which is a small, cylindrical column of copper, and a substrate, which is a flat, insulating material that serves as a base for the copper pillar.
Copper pillar assemblies are used to provide a secure and reliable connection between two layers of an electronic device, such as between a PCB and an IC. They are an important component in the packaging of electronic devices and are used to ensure the integrity of the electrical connection between the various components.
There are different types of copper pillar assemblies available, depending on the specific requirements of the application. They can be made from a variety of materials, including copper, aluminum, and other metals, and they may be coated or plated to improve their performance and durability. It is important to select the appropriate copper pillar assembly for a given application to ensure that it meets the required performance specifications and provides a reliable connection.
