8 & 10 Zone
Reflow
NR-800 &
10100 combines high mass heat sources with efficient thermal heat transfer to
allow for excellent reflow soldering results and throughput with a
shorter-than-average heating tunnel. It also includes as standard a number of
advanced features, including a wide combination pin-over-mesh belt conveyor, KIC
Auto Focus profile prediction software, and real-time thermal
profiling.
Features
- Affordably-priced, 8 / 10 zone "lead-free"
model to suit the most challenging high-volume production
requirements
- High-mass heat sources and efficient flow
design allow full, forced convection reflow in a footprint 20%-30% shorter than
comparable systems
- Independent upper and lower PID temperature
controls for each heat zone and three thermocouple inputs allow accurate
"lead-free" temperature profiling
- Combination 570 mm stainless steel mesh
conveyor and adjustable pin-type conveyor for PCBs up to 450 mm wide
- Nitrogen atmosphere compatible models
available with enhanced heating chamber flow design and PPM O2 analyzer
- Internal, water-chilled, recirculating heat
exchanger option for rapid, controlled cooling of liquidous lead-free
solders
- Easy-to-use Windows-based user interface
and password-protected control software with advanced temperature profiling and
thermal management functions
- KIC Auto Focus software included for
predictive profiling
- Timed automatic startup and shutdown modes
for power management and energy conservation
- Includes industrial PC, LCD flat-screen
monitor, keyboard, and trackball
- UPS battery backup to ensure product
protection in the event of power outage
- CE compliant.
Compact, High-Performance, Mid- to High-Volume SMT
Reflow Ovens
As higher temperatures and a tighter process
window reduce the margin for error in lead-free reflow soldering, Manncorp's
revolutionary NR Series reflow can provide many low-, medium- and even
high-volume manufacturers a reliable solution to these challenges, especially
when factory floorspace and budget are considerations.
Available in either 5, 6, 8, and 10 zone models,
CR Series reflow ovens are typically 20%-30% shorter in length than systems with
the same number of zones and of comparable throughput, with a lower price tag to
match. The key is a proprietary design featuring a combination of high mass heat
sources and efficient thermal heat transfer, resulting in uniform heating and
exceptional process stability despite varying loads.
Precise Temperature
Profiling
The NR-800 / 10100
heating zone temperature controllers have an accuracy of ¡¾1¡ÆC and, in
conjunction with a high-speed blower adjacent to each heat source for maximum
convection, ensure a ¥ÄT of ¡¾2¡ÆC across the PCB assembly. The system's diffuser
design also provides low-velocity, low-turbulence air flow to prevent component
shift or disturbance.
Optional thermocouples can be attached at
different, critical locations on the PCB, and connect to three built-in inputs
(standard) on the oven for communication with NR
Series control software and accurate, real-time temperature profiling to
match any solder paste manufacturer's specifications.
Included KIC Auto Focus profile prediction
software takes the guesswork out of setting up new profiles: simply select your
solder paste formula and process window, specify your product's physical
characteristics, and Auto Focus returns optimal zone temperature and belt speed
settings.
Conveyor
Systems
NR-800 / 10100 are supplied as standard with a
combination 570mm stainless-steel mesh belt and adjustable-rail, pin-type
conveyor system that handles PCBs up to a maximum of 450 mm.
To eliminate the possibility of jammed or
dropped PCB assemblies, all components are constructed of high-quality,
high-strength, stainless steel and are built to maintain dimensional tolerances
at the high temperatures of lead-free processing.
Advanced automatic chain lubrication and
motorized width adjustment are standard features on the pin conveyor. An
optional center board support system averts board warpage issues common to
larger PCBs processed at higher lead-free temperatures.
Conveyor speed is programmable from 400 ~1800mm
per minute to accommodate any production requirement.
N2 Atmosphere Compatible
LF Reduced Oxidation
While the debate over air or inert reflow
atmospheres continues, Manncorp, as an option, offers the NR-800 / 10100 in a nitrogen compatible configuration for
manufacturers who want the flexibility for soldering in both
environments.
Most experts agree that the reduction of oxygen
through the introduction of an inert gas usually N2 will allow a wider process
window and provide better solder joints through reduced oxidation. The enhanced
flow design of the heating chamber in the NR-800 / 10100 nitrogen-configured
system lends itself to efficient heat transfer and ensures low nitrogen
consumption while maintaining O2 levels between 300-1000 ppm.
Cooling Rates Required By Some LF
Solders
Because the higher liquidous temperatures
required by lead-free solders approach the limits of many SMT components and PCB
assemblies, more aggressive cooling is often required to reduce peak temperature
exposure times. Some recent studies also indicate that cooling rates have a
significant effect on solder joint grain structure.
For these reasons, an internal water-chilled
recirculating cooling system option is available for the NR-800 / 10100 model
and allows users to alter cooling rates to meet solder paste manufacturers
recommendations to a much greater degree than is possible with the exclusive use
of the standard air cooling system.
Advanced
Functionality and Process Management Capability
Operation and control of all NR Series reflow
systems is accomplished through an attractive, uncluttered user interface that
features a full-screen, virtual view of the system with display of pre-set and
actual zone temperatures, system status and conveyor speed.
The Windows-based oven management software
includes advanced functions for temperature profiling, timed automatic startup
and shutdown, audible and visual alarms, and password protection.
A PC-controller with 15" flat screen monitor,
keyboard and trackball allows unlimited storage and networking
capability.
All systems employ UPS battery backup to ensure
removal of all product from the oven in the event of a power outage.
