ApplicationsReflow Lead on Pin Connectors


A manufacturer reflowing lead on electronic metal pin connectors.

  • New Process - The manufacturer's customers presented a new requirement for the electronic pin connectors to be coated with lead.
  • Narrow Temperature Band - The lead had to be heated within a narrow temperature band to cause it to reflow.
  • Line Speed - The manufacturer would be increasing line speed from 30 to 80 feet (9 to 24.4 meters) per minute at some time after incorporating the new requirement into the process.
  • Heat - Two Model 5194-10 Infrared Line Heaters were used to heat the lead to reflow it on the connectors.
  • Power Control - A Model 5620 Phase Angle SCR Power Controller controlled the power to each of the heaters.
  • Instant On/Off - The quartz lamp in the Infrared Line Heaters heated up and cooled down instantly in response to power changes.
  • Precise Heating System - The Infrared Line Heaters, combined with the SCR Power Controllers, provided the manufacturer with a precise heating system that was able to consistently produce heat within the narrow band required to cause the lead to reflow.
  • Increased Line Speed - The Infrared Line Heaters provide enough heat output to enable the manufacturer to increase line speed to 80 feet (24.4 meters) per minute in the future.
  • Responsive Heat Source - The instant on/off capability of the Infrared Line Heaters made it easy for the manufacturer to handle line stoppages, and set up and troubleshoot the process.
