The Problem This Machine Solves

Precision micro-assembly requires reliable interconnection between fine wires, ribbon bonds, and component leads — but fully manual resistance welding introduces operator-dependent variability in force, timing, and electrode alignment. The result: inconsistent weld quality, intermittent connections, and rework that eats into production time. The SMSW II provides semi-automatic resistance spot welding with improved process consistency while maintaining the flexibility needed for precision micro-assembly work.

SMSW II Semi-Automatic Resistance Spot Welder

Semi-Automatic Precision Welding

The SMSW II is a semi-automatic resistance spot welder designed for precision interconnection applications. It improves welding consistency and process stability compared to manual welding, while allowing practical adjustment for different application conditions. The semi-automatic operation means the operator positions the workpiece, and the machine controls welding force and timing — removing the two most common sources of manual weld variability.

Key Specifications

Welding Type Semi-automatic resistance spot welding
Operation Mode Operator positions, machine controls force and timing
Process Control Better consistency than manual welding
Flexibility Adjustable for different welding conditions
Application Precision interconnection — fine wire, ribbon, component leads
Production Volume Development work and small-batch production

Applications

  • Fine wire welding — gold, aluminum, and platinum wire bonding on hybrid circuits
  • Ribbon bonding — flat ribbon interconnection for power devices and RF modules
  • Component lead welding — attachment of discrete components to substrates
  • Thermocouple attachment — precision welding of sensor wires to test fixtures
  • Micro-assembly interconnection — any precision resistance welding application requiring consistent force and timing
  • Development and prototyping — flexible setup for process development and low-volume production
  • Repair and rework — controlled welding for rework of existing interconnections

How It Works

The operator positions the workpiece under the welding electrode using the microscope and positioning stage. Once aligned, the operator initiates the weld cycle. The SMSW II controls electrode force, welding current, and weld duration — the three parameters that determine weld quality. The semi-automatic control eliminates force variation from hand pressure and timing variation from foot pedal inconsistency.

After the weld is complete, the operator inspects the joint and repositions for the next weld. The machine is ready for the next cycle immediately — no reprogramming needed between identical welds. For different welding conditions (different wire diameter, different substrate material), the operator adjusts parameters on the control panel.
