It was a resonant frequency that brought down the Narrows bridge. Memorex can shatter a wine glass with resonance. Ultrasonic washers use frequency to do what they do. If anything on the pcb has a length width or mass that resonates at the washers fr

Thanks for the info Patric...! Using that I found the resonator on the Manu's website. Armed with that and info I recvd on the PIC, I jumpered across the resonator and the board now functions. We'll be testing tonight with the Heli and see how it

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
