LA-306 Lab Furnace



LA-306 LAB IR LAB FURNACE LA-306 LAB IR LAB FURNACE

True near-infrared furnace. 
With models starting under $45k –
the LA-306 
is a compact – high quality
– general purpose furnace.

For those on a tighter budget, check out a reconditioned RTC LA-306 with 1-year factory warranty (in stock).

This small 6 inch wide chamber offers excellent temperature control
and rapid rise to 1000 degrees *C*.

Process atmosphere is controlled much like a clean room:
pressurized gas is pushed through the heating chamber insulation providing
a preheated, 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.

TYPICALLY USED:

The LA-306 is used in production and laboratory environments where
thermally controlled continuous processes are needed in a controlled atmosphere of nitrogen, forming gas or air.

It is available in a dual gas configuration, a second gas such as forming gas composed of nitrogen
and up to 4% hydrogen can be introduced into the furnace chamber while pure nitrogen is used in the rest of the furnace.

It runs on single phase 208 – 240 volt power.

It’s efficient when operated at 800 degrees *C*
it draws only 40 amps of current.

TYPICAL APPLICATIONS

The LA-306 furnace is used for controlled thermal processing
of product in a repeatable manner.

This furnace can heat to 1000 degrees C (1832 degrees F)
for thermal processing in a controlled atmosphere.

It’s use is for thermal processing of substrates, wafers, PCBs,
metal ingots and manufactured parts, ceramic, glass, optical coatings
and polycarbonate products.

Specific applications include:

Precise curing of coatings on optical lenses

General curing and drying

Semiconductor processing, Package Sealing, Epoxy Die Attach, Polymer Curing

Copper and hybrid thick film firing

Advanced thin film, crystalline silicon, cadmium telluride (CdTe alloys)
and certain copper indium diselenide (CIS-alloys) solar cell processing

Precious metal and alloy melting, brazing, annealing, tempering
and sintering applications.

All standard models (except LA-306 series and “P” models) include a RAID1 computer with LCD  screen,
full size keyboard interface
and both Ethernet and wireless-N high-speed network connections to facilitate view
and control of the furnace by managers and process engineers from any location.
Four (4) local USB ports are provided, convenient for connecting a furnace profiler and jump drive storage devices.

The new “P” series replaces the computer control system with high quality discrete digital controllers
for cost-effective precision control on repetitive production applications.
These furnaces are a good solution in applications where process recipes are changed infrequently and auxiliaries are at a minimum.
