Size 2, 5 1/2" (140mm) in length and 3/4" (18mm) wide, this brush is perfect for cleaning between components, e.g. capacitors, resistors etc.These brushes will allow for a complete and safe cleaning of sensitive components without generating any harmful static charges. You can clean your CPU, memory, motherboards, PCI cards, graphic cards and any other electrical component that is used in today's technology. These brushes are a must when cleaning your computer or any electronic sensitive components.Specification: Brushes minimize static charge generation and dissipate ESD charges to ground when held by grounded personnel.The handle is made of conductive plastic (104–106 Ω) and the comb is made of dissipative plastic (108–1010 Ω).Removes dirt on PCB, motherboards or other sensitive components, and discharges the static electricity to the ground.Always make sure you are grounded when handling electronic sensitive components.
