LT-050B-F/RF Light Force Manual Bonding Head – Thermode

Formerly known as 50F/RF

The LT-050B-F/RF Manual Weld Head is an air actuated, precision, low inertia head designed specifically for thermocompression bonding and hot bar reflow soldering applications. 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/RF 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 motion
  • Themode
  • Specifically designed for themocompression bonding and reflow soldering applications
