Canyon’s Ultrasonic Bath Procedure (Rev 3) outlines a controlled cleaning process used to remove contaminants from precision components prior to packaging or further processing.

<p data-start="0" data-end="775">Canyon&rsquo;s Ultrasonic Bath Procedure (Rev 3) outlines a controlled cleaning process used to remove contaminants from precision components prior to packaging or further processing. The procedure begins with reviewing customer requirements, followed by optional cleanroom preparation to achieve ISO Class 5 air quality when specified. The ultrasonic tank is then cleaned and filled with either a customer-specified solution or a standard 90% distilled water and 10% isopropanol mixture, ensuring proper fluid levels and compatibility with materials such as polyurethane. Parts are placed in baskets, fully submerged, and cleaned under defined temperature and time conditions, typically 140&deg;F for 15 minutes, with strict controls to maintain consistency and prevent contamination.</p>
