What it is

The Hesse & Knipps LW1089 is a laser welding system for fully and semi-automatic deep penetration welding.[1][2]

The LW1089 is positioned for joining aluminum and copper leads on DCB substrates and for other electronics manufacturing components in power electronics, battery cells, and modules.[1][2]

How it works

The LW1089 uses a laser beam to create intermetallic joints along a weld seam.[1][2]

The LW1089 uses temporal and spatial laser power modulation to produce different weld geometries and depths.[1][2]

The LW1089 includes an active vertical axis with sensor technology, touchdown detection, adjustable hold-down force, monitoring optics with ring light and image recognition, and process monitoring via sensors for process illumination and backscattered radiation.[1][2]

Where it fits in the process flow

The LW1089 fits after component placement and clamping and before final module use, because the machine is set up for clamped, position-controlled welding of leads and busbar connections.[1][2]

Applications

The LW1089 is used for welding Cu leads on DCB and AMB, welding Cu leads on Cu busbar, welding battery cells, and welding Al leads on Al.[1][2]

The LW1089 is intended for power electronics, battery cells and modules, and other electronics manufacturing components.[1][2]
