Throughout many steps in the semiconductor manufacturing process, Watlow
cable air heaters help to improve
process time and operating efficiency. Using clean hot gases significantly reduces wafer
drying time and
flameless dry heat efficiently solders and desolders electronic circuits and boards. Using
continuous elevated
temperature, gas streams quickly dry and cure circuit boards without using a large baking
oven, which would
take up precious space in your process.
Watlow's new in-line air nitrogen gas heater is specially designed for these
applications. The heater is engineered
to heat a flowing gas stream up to temperatures of 7600C and contains a small
diameter sheathed element which
allows for a quick response to both heat up and cool down cycles.
Because the element is sheathed, the unit can operate in gas streams that require a
clean environment as well as
atmospheres that contain contaminants and moisture. This provides superior heat compared
to an internally
exposed or open element wire which may fail due to particulates or moisture. Watlow's star
wound coiled cable
heater, used within the gas heaters, provides extremely efficient and reliable heating.
The stainless steel construction provides for a rugged, corrosion resistant assembly
which can be electro polished or passivated as an option. Thermocouples can be added to provide both precise control and
high-limit safety.
