{{Short description|Electrical connection material}}
A '''Fuzz Button''' is a high performance electrical connection material used to connect two parts of an electrical circuit together, for example an [[Integrated_circuit|IC]] to a [[Printed_circuit_board|PCB]] or two PCBs to each other. Fuzz Buttons consist of a single strand of [[gold]]-plated [[beryllium copper]] wire compressed into a dense, sponge-like cylindrical shape. Their diameter can range from a few tenths of a millimetre to a millimetre.<ref>{{cite book |title=Multichip module technologies and alternatives: the basics |last=Doane |first=Daryl Ann |author2=Paul D.

The term "Fuzz Button" was originally conceived and trademarked by Tecknit, but is now owned by a Denver-based company called Custom Interconnects.

==Practical uses==
This kind of connection is used in cases where permanent connection techniques like [[soldering]] or non-permanent ones like [[Pogo_pin|pogo pins]] or [[Elastomeric_connector|elastomeric "Zebra" connectors]] are not suitable, for example due to extreme vibrations or temperatures. They can also be used where low-distortion signal transmission is needed, like on PCB (board-to-board) interconnects, or in IC testing [[Jack (connector)|sockets]] where additionally many mating cycles are required. They can be used discretely as a signal/ground contact or for [[Electromagnetic interference]] (EMI) protection. When a mating array for multiple contacts is needed, like for [[Ball_grid_array|BGA]] or [[Land_grid_array|LGA]] IC packages, Fuzz Buttons can be placed in thru-holes in an insulated piece of material, such as dielectric plastic.

Fuzz Buttons are commonly utilized in satellite and space applications, but are also broadly used in military and commercial applications.
