TrackSlip PCB Solder Resist

TrackSlip® is a new low-friction surface finish for variable electrical tilt (VET) antennas. It does away with the need for a sliding interface under the phase-shifting element. A PTFE-loaded solder resist allows the elements to slide smoothly together many thousands of times without wear. As it is based on a conventional PCB solder resist, TrackSlip® is compatible with all standard PTFE and foam laminates. It can be applied using conventional resist techniques in complex, localised areas.
