PCB cleaning and solder bead cleaning
Application: PCB cleaning, solder bead cleaning, PCBA, solder beads, solder residues
Initial situation
The surfaces of PCBs are usually contaminated by machining processes (milling, grinding, drilling, punching). Impurities can lead to high scrap rates during further processing (equipping, painting). In addition, the solder beads may have to be cleaned off. Solder beads that adhere to the solder joints, but could accidentally come loose, must be removed to avoid malfunctions.
Solution
Unequipped PCBs or PCBs equipped with flat components are cleaned using a ROTORCLEAN cleaning unit. Ionisation electrodes (also available for ESD applications) reduce electrostatic charges and rotating brushes loosen unwanted particles from the surface. Make sure the PCBs are sufficiently secured during the cleaning process. The ROTORCLEAN unit can be swivelled upward for servicing. Loosened material particles are then transported to the ESUC/ESCA supply unit, by way of a suction channel or suction hose. If loose solder beads are to be removed reliably, the cleaning brush access to the problematic soldering areas must be ensured and the optimal positioning of the ROTORCLEAN cleaning stations determined, using sample parts in laboratory tests.
