In spite of all processes are no-clean, some part of the production should be washed. There are several reasons:
- Estetic – the board should be without any residual amount of the solder flux and other contaminated parts.
- Lack coating – the board should be clean, without any residua, prepared for lack coating.
- Decontamination – removal of ion contamination below 1,56µg NaCl / cm2 (J-STD-001)
To fulfill the severe requirements we do have the state-of-the-art equipment with closed loop circulation, regeneration of washing agent, online monitoring of conductivity. All residual parts from soldering are removed from the board.
