LT-050B-F/UB Light Force Manual Weld Head – Parallel Gap Electrodes

The LT-050B-F/UB Light Force Micro Welding Head is a manually actuated, precision, low inertia head designed specifically for thermocompression bonding. True vertical electrode motion eliminates electrode wiping action. Built in the USA, with a low mass spring and compound lever force system ensures accurate, repeatable welding force in the 125 to 1,000 gram range making the LT-050B-F/UB 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 and solar cells.

  • Low Force – 125 to 1,000 grams
  • True vertical electrode force motion
  • Exclusive “Unibond” electrodes
  • Specifically designed for thermocompression bonding applications
