RBM 402

The RBM 402 series is the highest highest developed brushing machine in our range. It is ideally suited for professional prototyping or small batch production in modern PCB laboratories. The machines perform double side operation. Upper and lower brushing rollers are adjustable in pressure and have a digital read-out. Oscillation and transport speed are variable. The wet procession system comes together with a powerful squeeze + hot-air dryer. The standard version KF - has a closed loop rinsing system with integrated rinse water tank, filter and pump unit. This saves the user money for fresh water and headaches about how to meet waste water regulations. On request we offer version F with external water supply. The "F" is indicating an integral, automatic filter system. That is urgently recommended in order to comply with German and European waste water pollution directives. These "F" machines are equipped with a 100 m filter tape (5 µm) and a waste water level control. As the tape load of filtered particles increases, the sensor will automatically start the filter transport, so that fresh filter tape is supplied. The last version of the RBM 402 is the BLC model. This is a simple benchtop machine with external water supply and no filter unit.
