4 PULSED HEAT CONTROL
990-908 3-5
NOTE: The
Reflow
temperature will always be higher than the actual melting point of the solder or heat
seal adhesives due to heat losses in both the thermode and parts.
Reflow
is shown as having a time length of 3.0 seconds and a set-point temperature of 350

C. Time can
be set for 0.1 to 99.9 seconds. Set-point temperature can be set from 60

C to 600

C.
Reflow
can also be
set in an extended temperature range up to 999

C
Cool1
You use
Cool1
to ensure that a solder joint or heat seal adhesive has solidified. If a Postheat stage is not
being used, an air actuated reflow soldering head or a heat seal head retracts the thermode from the parts
upon reaching the
Cool1
temperature. The
Cool1
parameter shows 200

C. Set-point temperature can be
set from 25° to 300°C. The
Cool1
time is not controlled.
Postheat
You can use
Postheat
to provide a higher temperature for when the thermode will be lifted off the
process part. This feature provides a reduction in contaminant buildup on the thermode. The point at
which during the Postheat stage when the thermode will be lifted is determined by the user setting for
Head Up Delay
.
Postheat
is shown as having a time of 2.0 seconds and a set-point temperature of 250

C. Time can be
set for 0 to 99.9 seconds. When it is set to 00.0 seconds, the
Postheat
state is omitted. Set-point
temperature can be set from 25

C to 600

C.
Cool2
You use
Cool2
to establish a temperature for the end of process. The
Cool2
parameter shows 150

C.
Set-point temperature can be set from 25° to 300°C. The
Cool2
time is not controlled.
Profile Description and Programming
The parameters contained in each profile are viewed and edited in two areas. The last two lines of the
GRAPH
screen contain the temperature and time settings for each process cycle. The two
Schedule
Setup
screens contain error limits, temperature envelopes, process and display parameters.
Temperature and Time Parameters
The temperature and time values are edited with the keys located on the front panel just below the
display. For detailed information on entering the temperature and time settings for a profile, refer to
