Not tried that one myself, couple of things though, the ultrasonic energy is going to have to have a sideways vector to "scub away" oxides. I am not sure if the systems normally used will do this or not. Second point is I recall that those ultrasonic welding systems rely on a Z axis force, and I am not sure what this will do to the shape/integrity of your FR4 PCB. TRY IT..............................

I think this will work, but I'm interested if anyone has applied this to PCB before? -----Original Message----- From: Rodney Miller [mailto:[log in to unmask]] Sent: Wednesday, March 29, 2006 10:06 AM To: 'TechNet ' Subject: Ultrasonic Weld to PCB with Ni Pads I have a component with Nickel lead, a battery, and soldering/tinning it has been troublesome. I want to Ultrasonically Weld the leads to the PCB. Can I do this with PCB FR4 Material. I was thinking if I cannot do it through the PCB laminate, I might add a Via in pad and fill the via with Nickel plate. The laminate is .030 and the finish option on the pads would be Selective Immersion Ni, plated up to ???? 10um Maybe? Any input appreciated.... Rodney L.
