Practical Set-Up & Qualification of Cleaning Process in Modern PCB Assembly

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 to eliminate selected failures. 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.

Topics will include: Testing boards, components and assemblies International specifications and reference books Ionic testing & non-ionic testing Surface insulation measurement Ion Chromatography (IC) test techniques Shop floor test methods Testing frequency during PCB fabrication & assembly Cleanliness failure types

After each webinar there is a Q&A session which provides ample time for all delegate questions to be answered. However if a delegate has a process example they would like cover in the webinar it will need to be provided in advance of the session.
