Nordson ASYMTEK introduces Qadence™, a closed-loop system that automatically compensates for viscosity changes during conformal coating. This innovative system combines the capabilities of Nordson ASYMTEK's conformal coating hardware and software to selectively apply coating to specific areas of a circuit board consistently throughout production. The Qadence flow control system maintains stable fluid application, flow rates, and performance by automatically compensating for viscosity changes related to temperature, humidity, and batch-to-batch variation. It eliminates the need for frequent operator adjustments and downtime to recalibrate the process.

Creep corrosion on printed circuit boards (PCBs) is the corrosion of copper metallization and the spreading of the copper corrosion products across the PCB surfaces to the extent that they may electrically short circuit neighboring features on the PCB. The iNEMI technical subcommittee on creep corrosion has developed a flowers-of-sulfur (FOS) based test that is sufficiently well developed for consideration as an industry standard qualification test for creep corrosion. This paper will address the important question of how relative humidity affects creep corrosion. A creep corrosion tendency that is inversely proportional to relative humidity may allow data center administrators to eliminate creep corrosion simply by controlling the relative humidity in the data center,thus, avoiding the high cost of gas-phase filtration of gaseous contamination. The creep corrosion relative humidity dependence will be studied using a modified version of the iNEMI FOS test chamber. The design modification allows the achievement of relative humidity as low as 15% in the presence of the chlorine-releasing bleach aqueous solution. The paper will report on the dependence of creep corrosion on humidity in the 15 to 80% relative humidity range by testing ENIG (gold on electroless nickel), ImAg (immersion silver) and OSP (organic surface preservative) finished PCBs, soldered with organic acid flux.
