II，The Preparation for Manual Soldering
1. First assemble the Heat Gun ‘Circular’ Air Nozzle Port to the casing of Heat Gun STEINEL
_3483, assemble it along the clamping slot, fix it and prevent shaking; then turn on the Heat
Gun STEINEL _3483 power and Set to II; Turn on the White Light Smoke Absorber, the
distance between Smoke Absorber and the PCBA to be soldered is usually 15cm.
2. Heat Gun STEINEL _3483 Air Outlet temperature, adjust the Heat Gun temperature
regulation button and wind force regulation button, to make the temperature of Air Outlet to
be 390℃ ±10℃，air force to be Step 1, as shown in Figure 13.
3. Pay attention to ESD protection, one must wear Electric-Static Discharge Wrist strap when
contacting PCBA board and components.
4. The position of hand holding Heat Gun handle is shown in Figure 14.

III，Operation Steps for Manual Soldering
When manually soldering SIM800H module to SIM800H-TE_V1.02 board,
SIM800H-TE_V1.02 board could be independently placed on the Repair Fixture; In addition,
during the manual soldering process, pay attention to the control of the Heat Gun Handle
position, tweezer position and Heat Gun heating time, to avoid the long time heating which will
cause PCBA delamination.

SIM800H module evenly with Soldering Flux Paste ---Coat the solder pad of SIM800H
module with Tin--- Correctly put the SIM800H module into the U101 frame of
SIM800H-TE_V1.02 board according to the silk screen printing or positioning pad--- Start to
solder SIM800H module with Heat Gun, withdraw Heat Gun after soldering, the solder is
completed.
Instruction of manual soldering operation:
1. Coat the solder pad U101 of SIM800H-TE_V1.02 board evenly with Soldering Flux Paste.

5. Correctly put the SIM800H module into the U101 frame of SIM800H-TE_V1.02 board
according to the silk screen printing or positioning pad, prepare to solder. The operation
instruction: (as shown in Figure 23)

6. Solder SIM800H module. The Heat Gun Power switch is in set II, the temperature is 400℃,
air force is grade 1, the soldering time of SIM800H module is about 180S. The operation
instruction: (as shown in Figure 24, 25)
Take the Heat Gun handle by the left hand, then make it vertical to the SIM800H module
mother board and revolve the Heat Gun slowly to preheat the module evenly, and keep the whole
welding frame stable. When continuous soldering time is about 130S, if the Tin around the

module begins to melt, use the tweezer gently stir the module PCB base board (Slightly stir, the
shift should be smaller than 0.5mm). If the module could not finish reposition automatically, it
means Tin in the heating place is not melted completely, so need to keep heating it with Heat
Gun, until when slightly stirring the module, it could do reposition automatically, then the
module soldering is complete, remove the Heat Gun and turn off power, the manual soldering is
finished.
The operation instruction is as in the following:

IV，Manual Disassembly of SIM800H Module (Rework Procedure)
When dissembling SIM800H module, the Heat Gun setting is same as the manual soldering (The
Heat Gun Power switch is in set II, the temperature is 400℃, air force is grade 1, the dissembling
time of SIM800H module is also about 180S.) The operation instruction: (as shown in Figure
26, 27, 28, 29)
1. When SIM800H module Tin begins to melt, put one of the tweezer tip into the tiny gap
between SIM800H module bottom part and TE terminal SIM800H-TE_V1.02, slightly and
stably take the SIM800H module.
2. Clipping the SIM800H module with tweezers at the right hand, stably clip it and place on the
surface of the welding frame, let it cool down naturally. The module could not be shaking or
flipping in the whole placing process, otherwise there is a risk that the electrical components
inside SIM800H module will be mislocated, and BGA bridge, which causes the module
damaged by human!

Caution: The Tin on the pad of dissembled SIM800H module will not be even and smooth
(as in Figure 30), do during REWORK, we need to absorb and remove the leftover Tin by
Soldering Wick before soldering, recoat with Tin to be relatively even and smooth, then
solder manually again.

V, Precaution Consideration of Manual Soldering
1. After using the Heat Gun, it should be placed in the welding frame steadily, and be cautious
that the conduct wire, plastic items and other miscellany will not touch the Heat Gun Air
Nozzle, to avoid burning the wire, and cause electricity leakage accident.
2. When the Heat Gun power is on, the temperature of Heat and Hot Air near the Nozzle is
about 100～450℃ high, so make sure don’t touch Hot Air or the metal part around the
Nozzle, don’t use it near the inflammable gas or material.
3. If you don’t use Heat Gun for a long time, please turn off its power.
