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

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

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

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?

First, don't exceed the maximum temperature of the battery, say 85*C [I don't know your specifics] Second, don't short the terminals of the battery. Third, the best way to wave solder a battery is: * Insert an insulating tab between the battery an

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

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

Yes, you can rework your thermocouples, but consider using a method other than arc welding. Arc welding can join thermocouples, but it uses a filler. The filler adds a third material that affects the slope of the thermal profile. We rework our the
