A persistent myth or presumption exists in the electronic market regarding ultrasonics generally damaging components on circuit boards. Machine suppliers and standardization organizations such as the IPC however implemented innovations and improvements to prevent damage caused by ultrasonics. 

The present Whitepaper will show how modern ultrasonic cleaning works and how methods to prevent harm are used effectively. Correct choice of frequency, setup of parameters and relative movement of goods to clean are essential for gentle cleaning. Standardized testing methods carried out prior to establishment of a cleaning process can ensure gentle cleaning.
