CR6000 Compact, Cost-Effective Lead and Lead-Free Reflow Solution
Manncorp's revolutionary CR6000 provides low, medium, and high-volume PCB manufacturers with a reliable solution to the challenges of lead-free reflow soldering, including higher operating temperatures and tighter process windows with minimal margin for error. Its 6-zone design is 20-30% shorter than comparable systems offering the same number of zones and similar throughput, making it ideal for facilities where both floorspace and budget are limited. This performance and value are made possible by a proprietary design that combines high-mass heat sources with efficient thermal transfer, delivering uniform heating, exceptional process stability, and consistent results even under varying product loads.
Precision Temperature Control & Advanced Thermal Profiling
The CR6000 is engineered to fully support lead and lead-free manufacturing, combining an industrial computer with PLC and SSR control to deliver reliable, high-stability operation. Advanced PID temperature control maintains heating zone accuracy to within ±1°C while high-speed blowers positioned at each heat source maximize convection to ensure a ΔT of ±2°C across the entire PCB assembly. The CR6000 also provides accurate, real-time temperature profiling to meet the requirements of any solder paste manufacturer, delivering consistent and repeatable reflow results. Profiling software integrates seamlessly with included thermocouples that attach to critical PCB locations and connect to three standard CR-series thermocouple inputs for precise thermal measurement, process verification, and optimization. A specially engineered diffuser design produces low-velocity, low-turbulence airflow, preventing component shift.

Flexible, High-Precision Conveyor System
Designed to meet a wide range of product specifications and production requirements, the CR6000 features a standard 22-inch (570 mm) stainless steel mesh belt combined with an adjustable-rail, edge pin-type conveyor capable of handling PCBs up to 17 inches (430 mm) wide. Programmable conveyor speeds from 16 to 71 inches (400-1800 mm) per minute allow precise process matching, while width adjustment can be performed manually or with motorized control. A mechanically guided lower chain structure and three-point simultaneous rail width adjustment ensure stable PCB transport without distortion. All conveyor components are constructed from high-quality, high-strength stainless steel for dimensional stability at lead-free processing temperatures, and the oven comes standard with automatic chain oilers to prevent jams and ensure reliable, long-term operation.
Advanced Oven Control Software & System Safety
The CR6000's Windows 11-based oven management software delivers comprehensive, secure process control with advanced temperature profiling, timed automatic startup and shutdown, weekly scheduling, delayed power-off, and audible and visual alarms. An intuitive, full-screen graphical user interface provides a clear virtual view of the entire system, displaying preset and actual zone temperatures, system status, and conveyor speeds for simple, efficient operation. Users can set, save, and recall oven temperature and conveyor speed parameters, while built-in PCB temperature profiling allows profiles to be tested, reviewed, and printed for a complete process documentation. Each system is equipped with a 15-inch flat-screen monitor, keyboard, and trackball, offers unlimited recipe storage and networking capability, and includes a built-in UPS battery backup to ensure all product can be safely conveyed out of the oven in the event of a power outage.
Safety, Monitoring, & Expandability
System safety and visibility are enhanced with a signal light tower indicating operational status, along with malfunction alarms and real-time status display on the LCD. Operation logs can be recorded for traceability, and a UPS battery backup with automatic delayed shutdown ensures PCBs are safely conveyed out of the oven during a power outage. The system is nitrogen-ready, allowing nitrogen capability to be added at a later time as production requirements evolve.

How 'Auto Focus Power' Profile Prediction Works:
1. Select Your Solder Paste Formula and Process Window
The KIC Auto-Focus Power software includes a database of over 1000 different solder paste formulas from dozens of different solder paste manufacturers. Each database entry includes the manufacturer's recommended solder profile for that specific solder paste formula and identifies critical specifications (i.e. maximum ramp rate, maximum cooling rate, temperatures for preheat, soak, reflow, and peak, allowable times above those temperatures, etc., with upper and lower limits for each) that define the process window. After selecting the solder paste, users can either use the profile as is or can modify the specifications to create a process window that meets their own unique criteria.
2. Link Your Product to the Process Window
Once the Process Window is selected (defined), the next step in using Auto-Focus is selecting the product to be soldered (or assigning a name if the product has not yet been defined). This step, in effect, links the product to the selected process window. It also links the process window and the product to the CR Series Oven data in the database. The oven data has been produced by KIC's characterization of the unique thermal properties of specific CR Series oven models as they relate to varying product sizes and processes.
3. Define the Product's Physical Characteristics
The user now enters the average length, average width, and total weight of the product.
4. Obtain and Confirm the Oven Settings
Auto-Focus now scans the built-in database for zone temperature/belt speed settings that produce a thermal profile that best fits within the process window when soldering a similarly sized product. By comparing that profile to the desired process window, Auto-Focus is able to estimate the PWI™ (Process Window Index); a single value that will give the user an indication of how far "within spec" the actual profile will be when using the recommended oven settings. If the PWI value is acceptable, the user can then obtain the exact temperature settings for each zone along with the belt speed.
