8014-RTC-LA-306-BELT-FURNACE

This special RTC LA-306 with a 38-inch UNLOAD station recently underwent complete reconditioning in the factory.

At 50-60% of the price of a new furnace, you get a furnace that can be used for another 10-15 years with an all new control system, new furnace chamber internals and all new aircraft aluminum cooling section. These units are fully tested to RTC oem factory specifications and are guaranteed functional for one year from date of receipt.

Compact High Temperature Infrared Thermal Processing Belt Furnace

True near-infrared furnace.The LA-306 is a compact high temperature production and laboratory infrared furnace. The small 6 inch wide chamber offers excellent temperature control and rapid rise to 1000°C . Process atmosphere is controlled much like a clean room: pressurized gas is pushed through the heating chamber insulationproviding a pre-heated, laminar flow for a uniform, stable atmosphere. Precise temperature is maintained by control thermocouples above the belt in each zone quickly sensing changing conditions. IR quartz heating lamps inside the chamber instantaneously adjust their output to achieve tight temperature control: each load through the furnace sees the same temperature. The small size and furnace chamber assures good temperature control with efficient use of power and proces gas.The LA-306 furnace can be configured for one gas (CDA, Nitrogen) or dual gas operation (nitrogen and forming gas).The furnace is operated via individual digital PID controllers to control the temperature in each zone.For efficiency and smooth control, phase-angle fired SCR's are used to power the lamps.

Process Applications

The LA-306 can process substrates, wafers, PCBs, metal, ceramic, glass or polycarbonate parts for Package Sealing, Epoxy Die Attach, Polymer Curing, Reflow Soldering, Hybrid/Thick Film Firing, General Thermal Processing, Brazing, Annealing, Tempering andMetal Sintering applications.
