The principle of reflow soldering is divided into several
descriptions
A. When the PCB enters the heating zone, the solvent and gas in the
solder paste evaporate, and at the same time, the flux in the
solder paste wets the pads, component ends and pins, and the solder
paste softens, collapses, and covers the solder The pads isolate
the pads and component pins from oxygen.
B. When the PCB enters the heat preservation zone, the PCB and
components are fully preheated to prevent the PCB from suddenly
entering the welding high temperature zone and damaging the PCB and
components.
C. When the PCB enters the soldering area, the temperature rises
rapidly to make the solder paste reach a molten state, and the
liquid solder wets, diffuses, diffuses, or reflows to the PCB pads,
component ends and pins to form solder joints.
D. The PCB enters the cooling zone and the solder joints are
solidified; when the reflow soldering is completed.
Other Information of Reflow Oven
01. High temperature
The machine is easy to malfunction in the high temperature
environment, thus affects the production. Manufacturers do not know
the cause of thecase that is mechanical damage, only normal use,
attention to maintenance and micro-repair, these mechanical failure
control.
02. Voltage problem of Reflow Oven
After-sales service manufacturers often encounter customer response
tomechanical failure, such as mechanical heating can not work,
unable torotate control display instability.
The causes of the above failures, in addition to a few poor
quality, most of the voltage is not enough, capacityis not enough,
line aging and lead to imbalance between circuits. If it isnot
repaired in time, the machine will burn out.
03. Professional maintenance of Reflow Oven
Equipment professional electrical maintenance personnel, regular
maintenance and repair of machinery.
Can also be under the guidanceof manufacturers to do a good job in
the daily maintenance and regularmaintenance of machinery.

RFQ About Reflow Oven
We have power limited in factory, how we can use your reflow oven,
and avoid over-load trip when start up the machine ?
According to actual situation, we can make changes on machine
software, and when start up the machine, the heating zones will be
heated on one by one, it means the start up power is very low, so
it will be no problem; also the customer can operate the reflow
oven by manual mode, it’s very easy to set all parameters in the
software.
