The National Physical Laboratory (NPL) will hold a webinar on surface insulation resistance (SIR), conductive anodic filament (CAF), and condensation testing on July 17, 2018, at 14:30 (UTC).
The webinar will discuss the advantages of using SIR testing to evaluate assembly processes and materials. It discusses test vehicle design, how to go about the testing and how to analyze the results. CAF testing will also be covered, including test vehicle design, test procedures and parameters, and failure analysis. The final part of the webinar will cover condensation testing and how it can be used to assess conformal coatings.

Industry experts are saying that Resistivity of Solvent Extract (ROSE) testing should be retired as a cleanliness or process control test in the PCB assembly industry. This article emphasizes that position by highlighting some work by the authors comparing component cleanliness results from the ROSE against Ion Chromatography (IC) results.

To ensure that a complex electronics build can be completed on time, on budget and with zero defects, here is a list of checks and balances that will help you with adjustments or corrections real time, instead of discovering them at the end of the build or worse, when it's already arrived at the end user.
