Material Characteristics:
Heating Wire :All heating device is the vacuum super long life Ni
Cr Heater;(This material heater is essentially different from
stainless steel heating tube and quartz heating tube ). In terms of
production process, all the heat sources are protected by double
insulation of magnesium oxide tube and magnesium oxide powder to
ensure safe and reliable use. On this basis, vacuum technology is
used to remove the internal air inside the heating body, and then
insulating porcelain sleeves are installed on both sides and sealed
with high-temperature glue to disconnect the air from the heating
wire, so as to ensure that the joint solder joint will not be
oxidized and broken when heated at high temperature, Further extend
the service life of heater.
Temp Sensor: All of them are K-type thermocouples with a maximum
temperature of 1100 ℃. The sensor probe adopts exposed package to
ensure the maximum sensitivity. Generally speaking, the response
speed of temperature fluctuation will not exceed 2 seconds; Due to
the sensor probe is of exposed design, the temperature response is
sensitive, the difference between the sensing temperature and the
measured temperature is relatively small, the temperature setting
target value and the actual air temperature will not exceed 1℃
Design Feature:
In line with the principle of energy conservation and environmental
protection, we have added the design of air guide and accelerator
in the design, which is mainly to prevent return air. After the
wind enters from the outside, it can only circulate in the
internal, low heat flow loss, high thermal efficiency, so as to
achieve the purpose of energy conservation and environmental
protection .
Uniformity:
In order to make the uniformity in the furnace better, we adopt the
design of driving motor with wind wheel. The light aluminum wind
wheel makes the driving motor load small and the service life long.
The design of the wind wheel makes the thermal cycle in the furnace
better, the thermal compensation faster, so that the uniformity is
better, power saved. The upper six lower six standard 6 zone reflow
oven uses about 3.5KW per hour.
Advanced structural design:The heating device adopts forced
turbocharged hot air microcirculation system, which has the
advantages of rapid temperature rise, super fast thermal
compensation reaction rate, generally less than 2 seconds, and
excellent temperature uniformity and heating efficiency; The inner
liner adopts integrated design, and the K-type mirror stainless
steel material has superior thermal insulation performance, never
deforming, easy to clean and maintain.
Uniform temperature and excellent performance: The hot air
circulation system ensures that the temperature in the furnace is
uniform, and each temperature zone has good isotropy, which can
significantly improve the influence of temperature curve crossing
on PCB solder joints, effectively prevent the influence of air flow
between temperature zones, and ensure the temperature control
accuracy.
Fast Heating Rate: Due to the reasonable structure design and the
electrical part is used properly, it takes only 8 minutes from room
temperature to set temperature.
Lower power consumption: Due to the special design of the
structure, high thermal efficiency and rapid heating, the power
consumption per hour is less than 3 kw
Humanized design of operation panel :Easy operation within 15 min
Accurate temperature control :Unique design, micro computer
control, deviation less 2 degree.
Scientific materials and excellent quality :Vacuum Packaging,
isolated from the air, super long service life of the heater
It is widely used and versatile :The wind uniform and large heating
capacity, suitable for all chips and IC welding, Independent
circulation and temp control
Easy to adjust and practical:Suitable for all Temp curves, easy of
debugging and time saving
Cooling fast: The outlet part is equipped with cooling zone,
generally, only furnaces with 8 temp zone is equipped with cooling
zones. In order to meet the welding needs and ensure the welding
quality, we add the cooling zone in this equipment, also and
prevent operators from being scalded by high temperature during out
board detection .
