Features:
1. This machine has the strong and perfect function selection, with eight temperature
waves in the memory software, you can select the right temperature wave according
to the solder/unsolder request.
2.Intelligent temperature wave heating, can achieve the solder/unsolder automatically.
3. Three-dimensional adjustable lamp body, use laser light, suitable for unsoldering
any-angle components.
4. PID intelligent temperature control can avoid the IC damage due to the fast or
uninterrupted warming up.
5. This machine has a super hot melt system, use infrared welding technology which
is developed independently, heat is easy to pierce and distribute evenly, can suit for a
variety of computer, notebook, play station’s BGA components, especially in a
Northbridge/ Southbridge chipset of computer.
6. Friendly human-machine operation interface, perfect LCD display, you can watch
the whole repairing process very clearly.
7. Ergonomic design, practical and easily operated. Good build quality but at the
same time light weight and a small footprint allows the T-890 to be easily bench
positioned, transported or stored.

Operating instructions:
1. Examination and operation,
1). Place this machine on an even surface with good ventilation and no combustible
items nearby. Leave at least 20mm on either side because the machine will emit heat
when in use. Check the power supply voltage, connect the machine with the power
supply, turn on the power switch, the LCD screen will display as follows:
5-1：Main manu page
2) Press “F1” button (about 2 seconds) the preheating chassis starts to work, press
“F1” button again to stop.
3). Press “F3” button enters to the PCB temperature adjusting page, press “F2” select
different page, press “F3” select the temperature wave. The example shows wave 3.

4). Press “F2” button, the infrared lamp start to heat up as the presupposed
temperature wave.
5-3：the LCD screen display page
5). When the process finished, return the previous page automatic. If you want to stop
in the process, press “F3” button.
2. The wave selection and setting
1). Press “F2” button enters to the select/set page, firstly, set the preheating chassis
preheat temperature, press “F3/F4” buttons up and down to select different
temperature, press “F1” button to save. When save succeed, the LCD screen displays
as follows:
2). Press “F5” button, come to the Main Manu page, press “F2” button enters to the
select/set page, the LCD screen displays as follows:
The preheater temp
The lamp temp
The preheater temperature

3). Press “F2” button enters to the select/set page, following we provide eight
different wave cycles, please choose one according to your request, press “F1” to
confirm the wave you choose, press “F2” button, come to the Main Manu page
4). If you want to reset the wave, press “F5” button, when it flicker the grid, you can
set. Press “F3/F4” buttons up and down to select different temperature, press “F1/F2”
buttons forward and backward to select different time, press “F5” button to save.(the
grid disappear, change to the previous flicker status), press “F4” button come to next
Segment, the same method to set the wave, press “F1” button to save the current
wave.

5). Press “F2” button, the lamp starts heating up according to the setting temperature.
6) Each temperature wave purposes as follows:
Wave one; use the same with soldering the less lead paste, like 85Sn/15Pb 70Sn/30Pb
Wave two; use the same with unsoldering the less lead paste, 85Sn/15Pb 70Sn/30Pb
Wave three; use the same with soldering the more lead paste, like 63Sn/37Pb
60Sn/40Pb.

Wave four; use the same with unsoldering the more lead paste, like 63Sn/37Pb
60Sn/40Pb.
Wave five; use the same with soldering high-melting-point lead-free paste, like
Sn/Ag3.5；Sn/Cu.75 Sn/Ag4.0/Cu.5 Sn95.5/Ag3.8/Cu0.7
Wave six; use the same with unsoldering high-melting-point lead-free paste, like
Sn/Ag3.5；Sn/Cu.75 Sn/Ag4.0/Cu.5 Sn95.5/Ag3.8/Cu0.7

Wave seven; use the same with soldering lead-free solder in melting point, like
Sn/Ag2.5/Cu.8/Sb.5；Sn/Bi3.0/Ag3.0
Wave eight; use the same with unsoldering lead-free solder in melting point, like
Sn/Ag2.5/Cu.8/Sb.5；Sn/Bi3.0/Ag3.0
Attentions:
1. According to the chips size and welding technological requirements, select the
right wave to unsolder the chips, use tweezer or vacuum nozzle to remove the chips.
2. Infrared lamp temperature wave set, temperature and the rate of time can not be
greater than 2 ℃/ S, each time setting value cannot exceed 250 seconds.
3. If you want to reset to Factory Default, press “F1” and “F5” at the same time, then
turn on the power switch, when heard continuous buzzer is ok.
4. There are a lot kinds of solder paste, every company chooses is also not identical.
