The
need for true Thermal Shock testing has been expanding rapidly due,
in part, to the enormous competitive pressures existent, particularly
within the general electronics industry. The utilization of these latest
technological advances for applications in medicine, computer technology,
space exploration, defence research, even the automotive industry, are
testimony to the increased necessity to produce products with the highest
possible reliability quotient.
Clearly,
thermal shock testing does provide the means to achieve this reliability
objective. Currently, more and more manufacturers are turning to full
temperature cycling or thermal shock testing of their electronic components,
semiconductors, computers, instruments and peripheral electronic equipment.
Thermal
Shock Chambers allow the test specimen to be automatically
and repeatedly transferred from a hot environment to a cold environment
or the reverse of this temperature sequence. This process is defined
as true thermal shock, as opposed to thermal cycling, wherein the specimen
is introduced into the chamber and the chamber temperature is then cycled;
a process which may require two hours to ramp up or down and attain
a similar 265°C temperature variation.
Our
Systems offers both a Two Station and Three Station Thermal
Shock Chamber. The upper compartment provides the heated environment
while the lower compartment provides the cold environment in both the
two and three station chambers. The three station chamber also contains
a middle compartment between the hot and cold compartments. This middle
compartment is exposed to room ambient (ambient dwell) and is enclosed
with expanded metal. Each type chamber contains a specimen holding basket
(transport carriage), which is pneumatically operated from a compressed
air source.
