SMD Hot Air Tool
OPERATING REQUIREMENTS:
•230V, 50 Hz
•Regulated air ow
SPECIFICATIONS
• 230V, 70 W
• 6.5 oz. (184 g)
• Temperature range: 4000F - 8000F (2050C - 4250C)
• Temperature regulation: ±60F (±30C)
• Voltage leakage from tip to ground less than 2 MV
• Tip to ground resistance less than 2 ohm
• Complies with MIL-S-45743E, DOD-STD-2000-1B, MIL-STD-2000
WS6536E and ESD SPEC, DOD-STD-1686, DOD-HDBK-263.
CHANGING TIPS Efciency is greatly dependent on choosing the proper tip to meet each
application.
1. Have the proper Tip installed.
2. Connect Hose to regulated air source.
3. Plugged-in Tool to a power source and set
desired temperature.
4. Turn on the air and adjust pressure .
5. Direct hot air towards the connection until
solder melts. Using "SMD helpers" will make
your job easier.
1. Turn Tip counter-clockwise by using a WT618 Tip
Wrench. (set of 2, the other is to hold the RS321
Retaining Sleeve) or use a WT620.
2. Remove and replace with desired Tip.

CAUTION: HOT AIR WILL BURN

Pod when not in use
The 3 very important factors involved when working with the ATMOSCOPE SMD Hot Air Tool are amount
of air output, temperature setting and type of Tip used. The key to an effective soldering is to reow
the solder without blowing the solder across the board and thus creating bridges.
OPERATION
Cut thru the connection with a
pull wire or shim blade while
hot air melts the solder.

The following techniques are based on the manufacturer's point of view
and should only serve as guidelines. It's effectiveness will depend
on practice.
REWORKING SMDs
METHOD 1
(RECOMMENDED FOR GULLWINGS, LEADLESS CHIP CARRIERS and QUAD I.Cs.)
1. Install the proper Tip.
2. Adjust air output to 3-4 psi.
3. Set temperature to 700°F.
4. Using a WS630 SMD Pull Wire, thread the pullwire under the
leads of one side of the SMD and again thread the wire under
the leads of the opposite side.
5. Anchor one end of the Pull Wire to an unused hole of the
circuit board or maybe tape it securely to the board.
6. While directing hot air to the leads of the rst side, pull the wire
so that it will cut thru the solder connection.
7. After removing the two opposing side follow the same proce-
dure to desolder the remaining sides.
FA069
Fan Tip
8. To resolder, use a tweezer to hold SMD in place and align
the leads with the pads.
9. Use a Fan Tip whose width is as close to the size of the SMD
leads as possible.
10.Direct hot air on the leads and allow solder to reow. Release
SMD when solder solidies.
METHOD 2
(RECOMMENDED FOR LEADLESS CHIP CARRIERS)
WS630
METHOD 3
Dual-Flow Tip
1. Use a Dual Flow Tip whose width comes closes to the
width of the SMD component leads.
2. Adjust temperature to about 750°F.
3. Adjust air output at around 3-5 psi.
4. Position Tool on top of the SMD (air is directed on both
sides of the connection) and move back and forth, until
solder melts.
5. Lift SMD off the board by using a pair of tweezers.
6. To resolder, use a tweezer to hold SMD in place and
align leads with the pad.
7. Direct hot air to the leads and reow the solder.
Release SMD when solder solidies.
INSTRUCTIONAL VIDEOS AVAILABLE ON 30 DAY LOAN. CALL EDSYN.
1. Have the proper Tip installed.
2. Adjust air output to about 3-4 psi.
3. Set temperature to 700°F.
4. Heat up one corner of the SMD.
5. When the solder melts, insert the
shimblade of SMD helper under the
heated area of the chip as if cutting
thru the solder connection.
6. While directing hot air ahead of the shim
at all times, cut thru the sides of the
SMD and lift it up from the board.
7. To resolder, use a Quadra-Flow Tip.

TEMPERATURE CALIBRATION
1. Use the DS299S to remove the temperature
control knob. Remove RS321 sleeve. Turn
temp. control (A) so arrow points to cord.
2. Use the SRW01 to pull out heater assembly,
PCB & power cord from handle. Leave
enough power cord slack to install SRF30.
3. Place heater assembly, PCB & power cord
inside SRF30. Install RS321 and connect to
air source.
4. Follow set-up shown using of the MS412
Temperature Calibration System.
Includes:
•TI680
•SDS100
•FX635
5. Insert the hot air tip inside the TPL09-1,
place the center of the thermocouple wire of
the SDS100 inside the slot of TPL09-1 loca-
tor. Use only CLEAN thermocouple wires.
6. Turn on air, adjust to 5 scfh airow.
7. Turn temp. control (A) fully clockwise. Adjust
calibration pot (B) until reading stabilizes at
850°F.
8. Assemble unit in original handle.
