Gemini-4

Download

The Gemini-4 is a high performance laser shield scriber optimized for cutting foil shields and tinned micro-coax shields. Some key features include:

  • Compact bench-top system with one of the smallest footprints on the market.
  • Handles single wires through a single port or more complex cable configurations with the use of a mini-fixture.
  • Fast processing – up to 80″/s (2000 mm/s) strip speed for minimal thermal damage.
  • Dual laser galvanometer scanners strip wires from two sides to create a 360 degree incision around the wire.
  • Programmable dual axis (X & Y) motion to create any shape, including curves and hatched areas.
  • Ease of use – operator selects required recipe from a pre-programmed library via a touchscreen. Machine can also be activated by an optional foot switch.
  • Runs from standard electrical supply with no compressed air requirement.
Application

The Gemini-4 fiber laser system is optimized for cutting or vaporizing metal whilst being reflected or transmitted by most polymers. In other words, the laser does not interact with the polymer.

The Gemini-4 system can be used for:

  • Cutting of tinned braid / micro-coax shields, typically where the coax outer diameter is less than 0.01" (0.25 mm)
  • Cutting of foil shields, including those found in twin-ax type cables and aluminized mylar foil
  • Ablation of some bonded foils
  • Ablation of bonded metal foil shields from flat flexible cables (FFCs)
  • Ablation of polyimide wire.

When scribing micro-coax braid, the shield is tin-tipped in order to create a solid mass of solder and braid. The Gemini-4 is then programmed to cut a shallow groove in the shield. This "scribe" line is similar to the method used to cut glass. Once scribed, the shield snaps cleanly at the scribe line - cutting all braid strands at the same position. As the laser beam does not penetrate the braid, it does not matter what the underlying dialetric insulation composition is.

For foil cutting, the laser cuts through the thin foil layer. The laser radiation does penetrate to the underlying layers, so there is a small risk of heat damage. If the underlying plastic material is light colored (ideally white or transparent), the laser does not interact strongly and a robust cutting process can be developed for the foil. For dark colors (particularly black), it my be difficult to find settings that cut the foil without damaging the underlying insulation.

The system's unique and flexible software allows the operator to select from a color touchscreen the required settings (laser power, laser speed and strip positions) from a pre-programmed library and all strip parameters are automatically set. There is no need to program each laser move individually.
