Understanding NVR: Non-Volatile Residue in Electronics Manufacturing
In this episode of Ask Dr. Adam, he discusses Non-Volatile Residue (NVR) in electronics manufacturing, referring to the portion of chemistry that remains after heating. Dr. Adam explains that this residue consists of molecules with strong intermolecular forces that resist evaporation and that measuring NVR involves a simple yet precise process using a small tin and an oven.
He illustrates the measurement process, and states that NVR measurement is essential for assessing the health of cleaning solutions in manufacturing processes. A higher NVR indicates a dirtier solution, potentially compromising its ability to clean new contamination effectively.
Understanding and monitoring NVR helps maintain optimal cleaning processes, ensuring the quality and reliability of electronic components. By regularly measuring NVR, manufacturers can gauge when to refresh or replace cleaning solutions, ultimately improving the efficiency of their production lines.
