HELLER High Quality SMT Reflow Soldering Machine Full Automatic Leadfree Reflow Oven For PCB Production Line

Products Description :

Best value SMT Reflow Oven in the market. Designed for Low Cost of Ownership.

The 1700 models support high mix / medium volume throughput... at speeds up to 24 inches (60 centimeters) per minute, while conserving valuable factory floor space. Rapid response times and precise temperature controls assure process uniformity, regardless of component density or board loading, with identical profile performance in either air or nitrogen.


Highest Yields And Tight Process Control

  • The most efficient heat transfer from extra high volume, high-velocity, heating modules, producing heater module response of less than one second to temperature changes of less than 0.1ºC, thereby maintaining profile integrity for heavy board loads.
  • Wide process window for "universal profiling" - allows many different boards to be run on a single temperature profile
  • Advanced 5 thermocouple PCB profiling and process parameter logging capability with the capacity to store up to 500 temperature recipes and 500 profile graphs
