What Is a Gap Filler?
A gap filler is a specialized material designed to fill spaces between components in various applications, particularly in electronics and semiconductor devices.
This material serves several critical functions. In semiconductor devices and electronic circuit boards, it provides insulation by filling gaps between components. In electronic devices, gap fillers are used between heat sinks or cooling fans and the device itself to improve thermal conductivity, ensuring efficient heat dissipation. They also play a role in reducing vibrations and shocks among components, thereby enhancing the overall durability and reliability of the device.
Gap fillers are composed of materials like silicone, epoxy, urethane, ceramics, and conductive rubber. A notable variant is the thermal gap filler, specifically designed to manage heat within electronic devices by filling gaps that hinder effective heat transfer.
