SMT LEAD FREE REFLOW SOLDER
NITROGEN PROTECTION
AR 8820-480N2 SERIES
AR-6620
/ 7720 / 8820 / 9920 / 101020-480N2 is belonging to the upgrade version in
SMT lead free technology, the production capacity and
the accuracy of temperature control is more excellent,
and the efficiency will be increased 80% ,it is because
the temperature difference between the melting point
of lead free solder paste and the temperature allowance
of components will be decreased within 10℃~15℃. So,
the requirement of temperature control should be more
precision comparing with the initial soldering equipment.
Our Reflow System specialized high technology design,
which is combination with the physical & chemical
character of both PCB and flux, through the process
of raising temperature, even temperature, air convection
and cooling, allowing the precision and accurate temperature
control by the upper & lower hot air circulation
system. And lets the temperature of PCB will be achieved
the higher melting point of lead free technology, and
solve the problem of the decrease factor of ⊿T, satisfy
the temperature absorption
difference
between the large and small components, and balance
the even temperature in the heating zone......, which
is the real king of lead free soldering equipment in
the market.
 Precision
circulating convection channel,
increase
the heating efficiency and the accuracy of temperature
control.
AR
series focus on the lead free solder paste, not only
consider the general thermo graph of pre-heat even temperature
- reflow solder. And we expense a lot of experiment
and analysis reporting on trapezoid
heating
profile, which decreases heat deviations at peak temperature
and increasing solder flows, as a result to solve the
complex problems of the difference temperature absorption
efficiency of the components.
