The Laser Wire Solutions Gemini-4 cuts tinned micro-coax shield and aluminized foils as well as being able to ablate some bonded foils. The laser is strongly absorbed by the metallic shield causing it to vaporize. The laser is pulsed with very short duration pulses to ensure no heat is built up in the shield that could damage the underlying insulation. Once cut, the shield can be snapped off revealing the underlying layers. When scribing a foil or tinned shield, the laser light never penetrates to an underlying layer. When cutting foil it is often the case that the light does penetrate - in which case the effect on the underlying plastic layers has to be carefully assessed.
The main applications are for micro-coax shields where the coax outer diameter is less than 0.25 mm (0.01") and for cutting foil shields found in twin-ax type cables. Using the color touchscreen, the operator selects the desired settings (laser power, laser speed and strip positions) from the preprogrammed library and all parameters are automatically set. This unique software system avoids the need to program each laser move individually.
Gemini-4 begins the cutting process when the Operator starts the process via the touchscreen or via the optional footswitch.
The wires/cables are held in position via a configurable fixture plate or if the application allows, through a single entry port.
