Torsten,

We have done this at a previous employer, and the product was a side air bag control module.  The ultrasonic welder used, if memory serves correctly, was made by Branson, and was a rather large piece of equipment.  That's been a little over ten years ago...

Hi,

has anybody info about ultrasonic welding of plastic housing with electronic PCBs inside? We have done such process with simple mobile phone boards several years ago, but at the current project a gyro and an accelerometer IC are on the PCB, together with a lithium battery...

Alternative is laser welding, but that process is much more expensive...

Best Regards,
