4.When removing the chip, you can insert an IC puller at the
bottom or pin of the chip, and remove the chip after the chip is
fully melted.
5.During chip welding, clean the dirt and residue from chip pin
pad on PCB board. Apply the solder paste will be placed on the
IC pad, with the air gun at the IC pin pad to do circular movement,
so that the solder paste melting welding. When welding, pay
attention to the air nozzle should not touch the IC and IC pin
placed.
6.When dismantling and welding, please keep the bottom of the
workpiece hanging in the air (preferably the bottom of PCB), so
that the heat will not be absorbed by the bottom table. This
allows for better dismantling and welding.
Note:
Welding with hot air is effective, but it may lead to problems such as flux pilling,
flux overlay welding and tandem welding. If necessary,
use soldering iron to repair welding and remove residual slag.
1. When using this machine, please keep the power supply
reliably and well grounded, so as to have the effect of removing
static electricity. Keep away from flammable and explosive gases,
paper or other inflammable objects to prevent fire.
This product is high temperature and heating gas, please pay
attention to safety to prevent burns.
Cut and touch the heating tube of the drawing welding platform.
Cut the material so that the air flow out of the welding table con-
tact the body skin.
Cut objects by touching the working electric soldering iron.
2. It is normal for the air pipe to emit white smoke when the weld-
ing platform is first used, which can be eliminated after working
for a period of time.
3. The equipment is equipped with overtemperature protection.
For safety, overtemperature protection will be triggered when the
emperature of hot air drawing welding table rises to 580 degrees,
and the controller will forcibly cut off the load to make it no longer
