Printed Circuit Board (PCB) Cleaning Equipment

Nozzles are used in several complex manufacturing steps of printed circuit boards (PCB) production cleaning where equipment and parts must be entirely free from particulates.  After the sawing process, wafers must be cleaned so that no residue is present, since these are produced for microelectronics, photovoltaics and microsystems

Lechler nozzles in photovoltaic and printed circuit boards industry

printed circuit board cleaning equipmentFlat fan nozzles in sveral series-connected modules are used in this process.After the sawing process, the wafers are moistened with hollow cone nozzles.After the sawing process, the wafers are gently cleaned with full cone nozzles.Rotating cleaning nozzles for printed circuit board manufacture series 500.191. Rotating cleaning nozzles are used in horizontal continuous through-put systems for printed circuit board manufacture.Developing, etching, stripping.
Düsen für die alkalische Textuierung

Nozzles for alkaline texturing

  • Process specific application of flat fan nozzles in several series-connected modules.
  • Preferred application of nozzles made of PVDF due to their resistance to chemicals used in the individual processes.
Düsen für die Wafer Befeuchtung

Nozzles for wafer moistening

  • Application of hollow cone nozzles for moistening the wafers following the sawing process.
  • Hollow cone nozzles produce a fine spray mist that settles on the wafers. This ensures that no impurities dry onto the wafer, thereby also ensuring an efficient wafer production process.
Leiterplattenherstellung

Circuit board manufacturing

  • For the process steps of developing, etching and stripping regarding manufacturing circuit boards, different nozzles are applied in a typical inner layer line.
  • An example for the nozzles applied here is the series 646 nozzles with bayonet quick-locking system.
