During battery bonding, the wire is pushed against the surface to be bonded with a controlled force and a wedgetool. Then, the wire is vibrated at 60 kilo Hertz for 100 milliseconds. Advantages of wire bonding over spot or laser welding.
After the first bond is made, the bonding tool travels a defined pattern to form a loop of the disered height and length. The flexibility in shape of the loop is an additional advantage, especially when the battery housing is designed accordingly you can have benefits in durability of the battery pack.
You don’t want to use a too soft bond wire with respect to the harder electrolytic nickel surface of the cell. Since a battery pad behaves fundamentally different from a printed circuit board, the bonding parameters need to be adjusted. Battery pads behave differently from nickel-plated steel surface in both, the bonding and the BAMFIT test.
“It is a combination of three param-eters that forms the bond: vertical force, ultrasonic power and time,” explained McKeown. The process starts with a wire placed under the tip of a slim, rod-like bonding tool. A well-defined force is applied, pressing the wire onto the electrode surface and causing an initial cold-straining at the contact area.
The ultrasonic wire bonders from F&S BONDTEC offer the most flexible and advantageous connection techniques for battery cells in the battery pack production. In this best practice guide, we show what is important for the successful production of battery packs using ultrasonic wire bonding technology.
Hesse representatives Mike McKeown, Dr. Michael Brökelmann, Dr. Matthias Hunstig and Dr. Dirk Siepe describe wire bonding as an ultrasonic metal-metal fric-tion welding process. “It is a combination of three param-eters that forms the bond: vertical force, ultrasonic power and time,” explained McKeown.
