LT-050B Series Light Force Microwelding Head (formerly known as 50 series)

The LT-050B Series  Light Force Micro Welding Head is a precision, low-inertia head designed specifically for delicate, parallel-gap welding, thermo-compression bonding and reflow soldering. True vertical electrode motion eliminates the electrode-wiping action. A low mass spring and compound lever force system ensure accurate, repeatable welding force in the 40 to 1000 gram range. This makes LT-050B Series  perfect for wire and ribbon applications such as fine-trace circuit board repair, wire-wound potentiometers, hybrid microwave devices, pacemakers, electrical fuses, ordnance fuses, smart cards, solar cells and other thermo-compression bonding or micro-welding applications.

Key features LT-050B Series Light Force Microwelding Head 

  • 40 – 1000 gf designed to join fine wires and ribbons between 0.0003 in – 0.01 in thickness
  • Numeric force adjustment set with 3-digit numeric counter
  • No deflection through stroke ensures consistent electrode contact and avoids welding blowouts or inconsistencies
  • Configurable design accommodates a wide variety of applications
  • Manual foot or air actuation
  • May be fitted with an optional microscope for manual parts positioning
