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

Hi, I am experiencing cracked solder joints on ceramic resonators after the ultrasonic plastic weld process. PCB assy is placed into plastic housing and then housing halves are ultrasonic welded. Not a soldering problem. I know this component is
