2. Set so dering tip temperature to 250℃ (500℉ approx.) and deso dering tip temperature to min.
Coat the tinned surfaces with rosin-core so der after reaching 250℃.
3. Set to the desired temperature about 3 minutes after being warmed that the station wi be ready
for sue once it reaches preset temperature.
IMPORTANT:
Remove and c ean the tip dai y. If a new tip is insta ed, remove any oose bui d up in the barre
assemb y, otherwise the tip may fuse to the heating e ement or retaining barre .
METHOD TO CHECK FOR LOSS OF SUCTION
The fo owing procedures shou d be used on DIA100 to check whether oss of suction is due to the
tip, so der co ector, tube or in- ine fi ter.
CAUTION: THE DESOLDER SWITCH MUST BE “OFF” AND ALLOW THE IRON TO COLL
BEFORE ATTEMPTING THE FOLLOWING PROCEDURES:
1. Disconnect vacuum tube form the fitting on the front pane , p ace finger over the ho e of the
fitting, depress vacuum switch and you shou d have a strong vacuum. If not, send back to your
nearest service center for pump repair.
2. Disconnect the in ine fi ter from the iron assemb y, depress vacuum switch, rep ace fi ing of the

OPERATING PRECAUTIONS
1. Make sure both heater and nozz e are coo before attaching the nozz e.
2 . Caution High Temperature Operation
Both nozz e and hot air are extreme y hot and can cause burns. Never touch the nozz e and heater
assemb y or a ow the hot air to b ow against your skin. Initia y, the iron may emit white smoke,
but this wi soon dissipate.
3. Be sure to coo the unit after using. Whi e the power switch off, the unit wi automatica y b ow
coo ing air through the pipe for a short period of time. Do not disconnect the p ug during this
coo ing process.
4. Do not disassemb e the pump.
If the pump or other critica interna components become fau ty, discontinue its use immediate y. P ease
return to your vendor or its authorized repairers for proper servicing.
5. Disconnect the p ug whi e the unit is not in use.
When the power cord is connected into the power supp y, the unit has a itt e f ow of e ectricity;
even the Power Switch is in off position. So when you don’t use the unit for a onger period of
time, disconnect the p ug.
Operation Setup
1. Se ect the Nozz e that matches the size of the IC. Attach the nozz e when both heating e ement
and the nozz e are coo and the unit is turned off and unp ugged.
2. Loosen the screw on the nozz e and attach nozz e.
3. Press “▲” or“▼”key on the hot air function pane to choose the desired temperature or air f ow.
4. Press “▲”or “▼” key to choose the desired air f ow on the right side of the front pane . The
speed wi change 5 degrees by pressing the keys “▲” or“▼” at a time.
5. After adjusting the air f ow and temperature and wait for the temperature to stabi ize for a short
period of time.
IMPORTANT: Do not force the nozz e or pu on the edge of the nozz e with p iers. A so, do not
tighten the set-screw too tight y.

QFP De-soldering
1. Melt the solder: Ho d the iron so that the nozz e is ocated direct y over, but not touching the IC
and a ow the hot air to me t the so der. Be carefu not to touch the eads of the IC with the
nozz e.
2. Remove the IC: Once the so der has me ted, remove the IC by ifting the p iers.
3. Turn the power switch off: After the power switch is off, an automatic b owing function begins
sending coo air through the pipe in order to coo both the heating e ement and the hand e. So do
not disconnect the p ug during this coo ing process.
4. In case you don’t use the unit for a ong time, disconnect the p ug.
Note: After the power switch off about one minute ater, the temperature wi fa down to 75℃
(167℉) and power automatica y shut off.
5. Remove any remaining solder: After removing the IC, c eaning the remaining so der chips with
a wick or deso dering too .
Note: For SOP, PLCC etc. wou d recommend by using tweezers iron to deso der.
QFP Soldering
1. Apply the solder paste: App y the proper quantity of so der paste and f ux (preferab y no-c ean)
and p ace insta the SMD on the PCB.
2 Preheat SMD
3. Soldering: Heat the ead frame even y.
4. Washing: When so dering is comp eted, wash the area with a def uxer.
Note: Whi e there are many advantages of hot air SMD rework, it is a so possib e to have defects
for so dering BGA. Wi recommend to inspect a so dering joints c ose y.
