Can't say too much about the solder joints issue, but about a decade ago we did have a lot of problems with resonators being damaged by harmonics from Ultrasonic board washing & Ultrasonic welding. However this mostly manifested itself as cracking i

I've worked at several companies that have used Smart Sonic ultrasonic cleaners. About a year ago, we purchased the Smart Sonic 1550 and Enviroguard. The Enviroguard produces DI water for rinsing and also handles the solder waste. Also, Smart Sonic h

Hi Dale, I have copies of the articles of which Mike references. If you need copies for support, contact me at: bill@smartsonic.com. Rinsing should be done by ultrasonics also. Spray in atmosphere systems will not penetrate into the same tight ar

To get started, search the fine SMTnet Archives for discussion on stencil cleaners.

3) There are several papers on the safety of cleaning PCBs and ICs using ultrasonic technology. The latest is in the October 2004 issue of SMT magazine by William Kenyon, "Why Not Ultrasonics?" Most of the studies have been performed by Dr. B.P. Ri

The above suggestions look to be the most likely, however on the off chance: Going back a decade we saw damage to crystals & resonators due to induced harmonics from ultrasonics (usually in the wash). Some fluxer systems use ultrasonics (I think
