A precision laser welding system for semiconductor packaging uses highly focused laser energy to join metallic and hybrid components with micron-level control. Unlike conventional joining methods, laser welding is non-contact, highly localised, and programmable, making it ideal for sensitive semiconductor assemblies. The system integrates laser sources, precision motion stages, machine vision, and shielding gas delivery into a single platform. This allows accurate positioning, controlled energy input, and consistent weld quality while minimising heat-affected zones, particle generation, and mechanical stress on fragile semiconductor devices and substrates.

Micron-Level Welding Precision

Achieves extremely small spot sizes for accurate joining of miniature semiconductor components, lids, and contact pads without damaging nearby structures.

Minimal Thermal Impact

Controlled laser parameters ensure a very small heat-affected zone, protecting chips, wire bonds, and sensitive materials from thermal stress or deformation.

Hermetic Sealing Capability

Enables reliable sealing of semiconductor packages to protect against moisture, contaminants, and environmental exposure, extending device lifetime.

Advanced Machine Vision Integration

Vision-guided alignment ensures precise seam positioning and repeatability, reducing operator dependency and improving yield.

Flexible Welding Modes

Supports conduction and keyhole welding modes, allowing optimisation for thin foils, thick housings, or dissimilar material joints.

Dissimilar Material Compatibility

Effectively welds combinations such as stainless steel, kovar, invar, titanium, and specialised alloys commonly used in semiconductor packaging.

Automation-Ready Architecture

Easily integrates with robotic handling, conveyors, and PLC-controlled production lines for scalable manufacturing.

Rigid, Stable Machine Construction

Vibration-isolated structures maintain alignment accuracy and process stability even in high-throughput industrial environments.

Clean and Safe Processing

Shielding gas delivery and fume extraction interfaces ensure oxidation-free welds and compliance with clean manufacturing standards.

Semiconductor Packaging and Assembly

Used for micro-lid sealing, die-attach welding, and enclosure joining in advanced semiconductor packages and chip-scale devices.

Opto-Electronic and Photonic Devices

Supports welding of laser diode housings, photodetector packages, and optical sensor modules requiring precise alignment and hermetic sealing.

Telecommunications and Datacom Hardware

Enables reliable joining of transceiver components, optical sub-assemblies, and fibre-coupled modules used in high-speed networks.

Automotive Electronics and Sensors

Ideal for welding sensor housings, control modules, and LiDAR components that must withstand vibration and thermal cycling.

Medical and Diagnostic Electronics

Produces clean, biocompatible welds for implantable electronics, diagnostic sensors, and compact medical devices.

Consumer Electronics Manufacturing

Used for battery tabs, micro-connectors, and sensor modules in smartphones, wearables, and compact electronic products.

Aerospace and Defence Electronics

Supports hermetic packaging and precision joining of electronics designed for harsh environments and mission-critical reliability.
