Damage-free ultrasonically-assisted cleaning of printed circuit assemblies

Article Abstract:

Printed circuit boards can be cleaned by ultrasonic agitation with very little risk of damage as there is a wide safety margin. Any failure tends to be at the heels of bond wires, due to fatigue, when the original quality of the components is dubious. Susceptibility to ultrasonics has been shown by some components, such as QCDs and hybrids, where the safety margin is not so wide, but the process can be used so long as guidelines are adhered to.
