Workshop Introduction:
The majority of the industry worldwide have been running no clean processes for many years and have often, understandably, neglected important issues like design for cleaning, selecting compatible components and compatibility between cleaning materials and flux residues. With increased miniaturisation and the demands of modern circuits cleaning has come back into fashion. Conformal coating is another process which has demanded special levels of surface cleanliness to guarantee coating adhesion and long term reliability. Although there are high reliability produces that use coating with no clean others want that extra confidence.

Each delegate will receive a FREE set of cleaning inspection and quality control wall charts which also cover defects seen during assembly.

Workshop topics include:

  • PCB Design for cleaning
  • Testing component compatibility
  • Flux compatibility with cleaning solvents
  • Solubility of soldering residues
  • Cost of process chemistry and equipment
  • Inline or batch cleaning options
  • Process cleaning capability, simple shop floor analysis methods
  • Water, semi aqueous or solvent?
  • Simple steps to evaluate machine cleaning capability
  • Determining cleanliness standards
  • Ionic, SIR and visual inspection methods
  • Environmental requirements of cleaning
  • Cleaning no clean flux residuesWho should attend:
    This session is ideally suited to design, production and quality engineers looking at future technology and maintaining a company technology roadmap. It’s vital to subcontractors to be up-to-date with new technology and its possible implementation along with material and equipment requirements for future customers
