I have seen a small nickel pad (probably) soldered on PCB which is used to spot weld the other nickel strip coming from battery. I have seen them in chinese protection boards. I need to know how and where I can find them? Is there any technical name

Hi Nikhilesh, It was a long time ago, but we used to buy the nickel in reels then had a cut and feed station on the smt machine with selectable sizes. We did many types of boards in very large volumes, and usually the Nickel strip was soldered to t

In a new design project, I would like to attach electronic components to a board using either sonic or resistance spot welding. Anyone out there, who could provide me with actual parameters, like frequency, current and equipment used?

I assume that you're talking about wanting to solder to metal tabs that are spot welded to the battery terminal. These tabs are not meant to be soldered. The metal was special selected for welding. In the old days, you could buy plumbing flux at th

WE HAVE A NEED TO BOND SOME LOW TEMPERATURE LED'S TO A THIN CIRCUIT BOARD LAMINATED TO A HEAT SINK. HAS ANYONE USED AN ULTRASONIC WELDER TO WELD COPPER GUL WING LEADS TO A COPPER PAD USING ULTRASONICS? IF NOT HAS ANYONE USED RESISTANCE SPOT WELDING

Nothing to say that you can't purchase thermocouple wire and spot weld it in the machine shop at your local high school.

isd.jww: First, the original poster is talking about pads, not component leads. Second, you're correct that chrome plated component leads can be attached by spot welding or crimping a solderable tab to the lead and then soldering the tab to the boa

You can weld (spot) to chrome. Maybe you could weld a nickel tab to the chrome part?

Are you sure there is any "cleaning" needed? Can you see leftover bits of the teflon remaining? If so, work on it with an Xacto knife. But, most thermocouple wires are VERY hard to solder - as in practically impossible. Many of them have aluminum
