High-Heat, Lead-Free Soldering in a Shorter Tunnel

Our revolutionary CR6000 can provide low-, medium-, and high-volume manufacturers in a variety of PCB industries a reliable solution to the challenges posed by lead-free reflow soldering, including higher temperatures and a tighter process window resulting in a low margin for error.

Our 6-zone models are 20%-30% shorter than comparable systems with the same number of zones and commensurate throughput. They also offer a lower price tag than other options on the market, making them a great choice when factory floorspace and budgetary room are both at a premium. The key to this is a proprietary design that features high-mass heat sources combined with efficient thermal heat transfer capabilities, giving you the uniform heating and exceptional process stability that you’re looking for, even in the face of varying loads.

Precise Temperature Profiling

The CR6000's heating zone temperature controllers have an accuracy of ±1°C and, in conjunction with a high-speed blower adjacent to each heat source for maximum convection, ensure a ΔT of ±2°C 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 CR 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 choose your solder paste formula and process window, specify your physical characteristics, and Auto Focus returns optimal zone temperature and belt speed settings.

Advanced Conveyor Systems

No matter your product specification or production requirement, the standard combination 22” (570 mm) stainless steel mesh belt and adjustable-rail, pin-type conveyor system supplied with the CR6000 can handle PCBs up to 17.7’ (450 mm) in size at maximum. Conveyor speed is programmable in a range of 16”-71” (400-1800 mm) per minute to accommodate your needs. We also offer options such as automatic width adjustment of the pin conveyor based on specific reflow program parameter settings.

All of the CR6000’s components are constructed of high-quality, high-strength stainless steel, built to maintain dimensional tolerances at high lead-free processing temperatures while eliminating the possibility of jammed or dropped PCB assemblies.

Process Management Functionality

The CR6000’s Windows-based oven management software includes advanced temperature profiling, timed automatic startup and shutdown, audiovisual alarms, and password protection functionality. The control of this reflow system is accomplished through an easily navigable user interface featuring a full-screen virtual view of the system and a display of preset and actual zone temperatures, system status readings, and conveyor speeds. Every system features a UPS battery backup that functions in case of a power outage, ensuring the removal of all product out of the oven for your safety.

Our PC controller systems offer unlimited storage, networking capabilities, a 15” flat screen monitor, and keyboard and trackball.

Nitrogen Atmosphere Compatible

Our models offer nitrogen compatible configurations for manufacturers who want to be flexible in soldering in both air and inert reflow atmosphere environments. Experts agree that oxidation reduction through inert gas (generally N2) introduction allows a wider process window, providing better solder joints. Our nitrogen-configured CR6000’s heating chamber lends itself to efficient heat transfer and low nitrogen consumption while maintaining O2 levels of 300-1000 ppm through an enhanced flow design.

Critical Cooling Rate Control

Aggressive cooling is often necessary to reduce peak temperature exposure times in lead-free soldering processes due to higher liquidus temperatures approaching the limits of numerous SMT components and PCB assemblies. Our CR6000 utilizes an internal water-chilled recirculating cooling system which allows our clients to alter cooling rates, meeting solder past manufacturers’ recommendations to a greater degree than possible with exclusive standard air cooling systems.
