Q. What
Top Heat setting should you use?
A. Between 220-380C°.
Normal setting is 240C°
Q.
What’s the working distance of the IR Hand tool and how do I move it
for rework?
A. Approximately 5 – 10 mm when reworking and move up to 30mm
when removing Component – move the hand tool in a scanning motion to
heat leads, taking about one second for each scan of the component. Q.
What pre-heater setting should I use?
A. Between 200-290C°. Normal setting is 240C° Q.
How long do I preheat the PCB?
A. Always preheat the PCB (up to 120C°
for between 45 – 90 seconds) to allow the heat to conduct through to
the component before introducing the Top Heat. With the 700W
pre-heater the top of a small PCB will reach 120°
in approximately 45 – 90 seconds. Larger PCBs will take longer to
pre-heat. To check the PCB/component temperature, use a hand-held IR temperature sensor
(Not Supplied) to ‘look’ down at the PCB/component from about
60mm away and at about 45°
angle. |
