For “Nanotek” series, we have fine stainless wire brush called Nanotek Brush for IC socket maintenance. We also have “Nanotek Vacuum” which is nanotech brush combined with vacuum cleaner powered by your compressor or vacuum pump. Fine wires go into the gap of complicated shaped plunger tip and do excellent job of removing stuck solders on plungers by brush’s hardness and firm texture. We have 15types for Nanotek brush and 6types for Nanotek vacuum. Please choose what best suits your situation decided by how dirty the plunger is or I/O layout (location of connection terminal).
