Solder reflow heater bar assembly |
摘要 |
Heater bar assembly for a reflow solder machine comprises first and second fingers (50, 52) carrying U-shaped heater bar (54) which is pivotable on main member 22. A spring urges the heater bar assembly to the centered position. First and second thermocouples (82, 84) are secured to the heater bar (54) and are connected through a transfer switch (104) by which their electrical connections can be alternated. One controls the power supply and the other cuts off the power supply if temperature exceeds the selected temperature.
