Divergence in Test Results Using IPC Standard SIR and Ionic Contamination Measurements

Controlled humidity and temperature controlled surface insulation resistance (SIR) measurements of flux covered test vehicles, subject to a direct current (D.C.) bias voltage are recognized by a number of global standards organizations as the preferred method to determine if no clean solder paste and wave soldering flux residues are suitable for reliable electronic ...

Identifying Flux Residues

Why identify flux residues? The primary purpose of flux is to reduce species of metal oxides from solderable surfaces, and to act as a mechanism for lifting and removing debris. If the assembly is not properly cleaned after manufacturing, flux may continue to reduce metals and may eventually corrode the assembly. When the assembly is powered, the metal ions may ...

WHY test for Ionic Contamination?

Ionic contamination is a leading cause in the degradation and corrosion of electronic assemblies, leading to lifetime limitation and field failure (Fig. 1). Ionic residue comes from a variety of sources shown in Fig. 2 opposite: Examples of ionic contaminants: • Anions • Cations • Weak Organic Acid

PWB Contamination & Reliability DOE

This report hopes to achieve several goals: 1. Determine the link between bare PWB contamination, soldered assembly contamination and long-term product reliability. 2. Establish measurable limits for bare PWB cleanliness as well as process control limits for both an aqueous as well as a water-soluble soldering process. 3. Determine whether there is any correlation between ...

Comparison of Testing Methods for Residues on Electronic Hardware

In this white paper, we discuss the pros and cons of five analytical techniques when applied to residue analysis on electronic assemblies. We evaluate the following for their application and limitations for analyzing both visible and invisible residues: FITR, SEM/EDX, XRF, Ion Chromatography, and ROSE

█ Printed Circuit Board Assembly & PCB Design Forum

DEK APi X Calibration -- Our dek APi X started having alignment problems suddenly and we aren't sure why. The board is close, but mainly shifted toward the rear of the machine so we are not able to print with it. I performed reference alignment which works properly. I then did a vision calibration with the cal stencil and board, but this process doesn't seem to work properly. It goes through all of the motions and displays results, but when I try to do a test alignment with a board the alignment doesn't work anymore- fiducials are not detected. The fiducial box is also no longer a box but just a horizontal line. Restoring the vision defaults fixes the issue with the box being a horizontal line, but I am unable to calibrate the machine and get the alignment correct. Am I missing some step that is not in the procedure?

Fabmaster for window7 OS -- I need to download fabmaster for window 7 OS. I am upgrading the Spectrum ICT system from window NT to Window & controller and I need to download the fabmaster version for window7 OS. Any help or feedback is appreciated.
