FURNACE EQUIPMENT
1.1 Furnace Description
The LA-306 is a compact, near-infrared, conveyor belt furnace for laboratory and general purpose thermal
processing in the range of 100-980 C in a controlled atmosphere, free of outside contamination. Process gas
may be CDA, N
2
or another inert gas. Dual gas furnaces may use Nitrogen and a second gas such as Forming
Gas (pre-mixed N
2
/H
2
) or another type of reducing gas injected into the heating chamber.
Figure 1-1 Furnace Front Elevation
The LA-306 furnace transports product on a 150 mm (6-inch)
wide belt. In the standard design the chamber clearance above
the belt is 50 mm (2 inches). Optionally the furnace can be
ordered with 25 mm (1-inch) or 100 mm (4-inch) vertical
clearance above belt. LA-306 furnaces feature a hermetically
sealed heating chamber permitting control of the furnace
chamber process environment. Baffle sections before and after
the heating section contain curtains that hang down to just above
the belt to further isolate the furnace chamber from the room
atmosphere and from the cooling section.
The LA-306 can process substrates, wafers, PCBs, metal,
ceramic, glass or polycarbonate parts for electronic package
sealing, thermo-setting polymer curing, reflow soldering,
hybrid/thick film firing, brazing, annealing, tempering and metal
sintering applications, or almost any kind of general thermal
processing requiring precision temperature control in a
controlled atmosphere environment.
