Hot Bar Reflow Soldering & Bonding Systems

AMADA WELD TECH designs and builds integrated hot bar reflow soldering and bonding systems that combine pulsed heat process control with the bonding head, thermode, motion, tooling, monitoring, vision, software, and automation required for production.

Systems range from compact desktop machines and modular configurations to custom semi-automated and automated systems. Each can be configured around the specific parts, joining process, production volume, and automation requirements.

Configuring an Integrated Hot Bar System

A successful hot bar reflow soldering or bonding process depends on precise control of temperature, force, and time, as well as accurate positioning of the parts being joined. An integrated system coordinates these process variables with the motion, tooling, and automation required to perform the complete manufacturing sequence.

Depending on the application, a system may include:

  • Constant or pulsed heat reflow soldering power supply
  • Motorized or pneumatic bonding head
  • Application-specific thermode
  • Part-specific tooling and fixturing
  • Linear or rotary motion
  • Part height sensing
  • Machine vision
  • Hot bar process monitoring
  • Automated or robotic loading and unloading
  • Conveyor-based material handling
  • Connectivity to production networks

The system configuration can be tailored to the joining requirements and desired level of automation.

Hot Bar Processes and Applications

Integrated systems can be configured for several related manufacturing processes, including:

  • Hot bar reflow soldering
  • ACF bonding
  • Heat staking
  • Thermocompression bonding

Typical applications include flex circuits, ribbon cables, wires, flex-to-PCB connections, flex-to-LCD connections, and gold ribbon thermocompression bonding.

From Process Development to Production

Successful system integration begins with a proven joining process. AMADA WELD TECH manufactures pulsed heat reflow soldering power supplies and bonding equipment and also engineers the complete systems in which they operate.

Our applications engineers can evaluate customer parts and develop the joining process in-house before the production system is built. System engineers then integrate the required motion, tooling, controls, vision, monitoring, and automation into a solution designed around the application.

This coordinated approach provides a path from initial process development through a complete, production-ready hot bar reflow soldering or bonding system.
