Wire Bonder G5-2 – the first dual head wirebonder on a single chassis

Fully automatic, compact wire bonder G5-2 was adapted for the special requirements of mass production of power semiconductors and power modules in the automotive industry. It is the only wirebonder on the market offering the possibility to bond fine and heavy wire or heavy ribbon in a single machine.

Benefits:

  • Combination of fine and heavy wire/ribbon on a single platform
  • Wire from 17 to 600µm, ribbon from 2µm x 300µm
  • Rapid and easy bond head conversion in under 30 minutes
  • Continuous monitoring and control of the bond process - patented Bond Process Control (BPC 2000)
  • Comprehensive automation from manual to in-line solutions
  • In-head pull tester for non-destructive test of heavy wire bonds
  • In-line pull tester for rapid test of low wire count components such as lead frames, without slowing the production process.

Wire Bonder G5-XL – the first wire bonder with a working area of almost one square metre

With the XL wire bonder, as so often in the past, F&K Delvotec accomplished innovative pioneering work.
The largest work area in the world enables bonding of large components such as battery modules for electro-vehicles or solar concentrator cells (CPV).

Despite the large travelling distance the robotic arm remains vibration free and is positioned with micron accuracy.

Benefits:

  •  Largest work area on the market: 1.130 mm (X) x 700 mm (Y); 44" x 27"
  • Robotic arm moves the bond head completely vibration-free over the full working area
  • Access to the work area from all sides enables manual loading
  • Simple and rapid changeover of bond head within 30 minutes
  • Continuous monitoring and control of the bond process using Bond Process Contol (BPC 2000)
  • Comprehensive automation from manual to in-line solutions

Laserbonder – the worlds first laser wirebonder

Opening the door to a completely new technology.
Premiering in 2015, F&K Delvotec GmbH underlined once again the validity of its motto: Staying ahead in Bonding Technology.

This completely new process, based on laser micro-welding, is particularly suitable for joining wire onto battery terminals and onto DCB substrates and copper terminals in power electronics modules. US-laser bonding enables the use of higher guage ribbon bonding for much higher current capacity processes.

 In power electronics the phyiscal current carrying capacity limit using wire bonding will be reached at some point. With laser welding, connections of virtually any thickness can be joined but it is currently less flexible due to the requirement for pre-manufactured connectors.

Operating closely with the Fraunhofer-Institut für Lasertechnik (ILT) and S&K Systemtechnik, within the framework of the joint project RoBE (Robustness for Bonds in E-vehicles), supported by the federal ministry for education and research (BMBF), F&K Delvotec developed a technology that brought the best of both worlds.

 US-Laser bonding, offering aluminium and copper wire to be bonded onto DCB substrates and copper terminals not only expands the application area of bonding technology, it is also more robust than conventional wire bonding.
This allows secure and flexible connections of the terminals in battery manufacture and make the handling of connector strips superfluous.

Advantages:

  • New possibilities for precise and reproducible joining of copper or aluminium wire.
  • Processing connectors and bonding wires with a diameter up to 500µm
  • A robust process enables simple and cost-efficient electronic manufacturing
  • Lower demands on surface quality, cleaning processes and rigidity of work pieces compared to wire bonding
  • Bonding onto new surfaces and with new materials
