Compact, High-Performance, Mid-to-High-Volume SMT Reflow Ovens
When budget and floorspace are at a premium, but you still need precise, high-temperature lead-free reflow soldering with a tight process window, Manncorp's CR8000 offers an ideal solution for medium- to high-volume production. Its 8-zone design is 20-30% shorter than comparable ovens with the same number of zones, while delivering equivalent throughput at a lower price point. This compact, cost-effective performance is achieved through a proprietary combination of high-mass heat sources and efficient thermal transfer, providing uniform heating and exceptional process stability even under varying production loads.
CR8000 Precision Thermal Control & Real-Time Profiling
The CR8000 offers exceptional thermal control with heating zone temperature controllers that maintain ±1°C accuracy, while high-speed blowers positioned next to each heat source ensure a ΔT of ±2°C across the PCB assembly. Its diffuser design delivers low-velocity, low-turbulence airflow to prevent component shifts or disturbances during reflow. For precise, real-time temperature profiling that meets any solder paste manufacturer's specifications, thermocouples can be installed at critical PCB locations, connecting to the three built-in CR-series thermocouple inputs for seamless integration with the control software. For more precise profile prediction, use our optional KIC Auto-Focus Power Software. Equipped with an industrial computer, PLC, and SSR control, and advanced PID temperature regulation, the CR8000 ensures stable, repeatable thermal performance, making it ideal for high-volume production while minimizing the risk of soldering defects.
Flexible, High-Precision Conveyor System
The 8-zone oven is designed to meet virtually any product specification or production requirement with its standard adjustable-rail, edge pin-type conveyor combined with a 570 mm (22-inch) stainless steel mesh belt capable of handling PCBs up to 430 mm (17 inches) wide. Supporting double-sided and inline processing, the conveyor system enables fast, efficient changeovers for high-mix production environments. All conveyor components are constructed from high-quality, high-strength stainless steel to maintain precise dimensional tolerances are the elevated temperatures required for lead-free processing, eliminating the risk of jammed or dropped PCB assemblies. Standard features on the 8-zone model include advanced automatic chain lubrication, programmable conveyor speeds ranging from 400 to 1800 mm (16 to 71 inches) per minute, and motorized rail width adjustment using a three-point simultaneous adjustment system to ensure accurate alignment with no distortion.
Advanced Water-Chilled Cooling for Lead-Free Reflow
Aggressive and controlled cooling is critical in lead-free soldering, where higher liquidus temperatures push many SMT components and PCB assemblies close to their thermal limits. The 8-zone oven addresses this challenge with internal, water-chilled recirculating cooling that provides significantly greater cooling efficiency than air-only systems. This design allows precise adjustment of cooling rates to reduce peak temperature exposure time and more accurately match solder paste manufacturers' recommendations, helping protect components while improving overall process control and repeatability.
High-Efficiency Flux Filtration and Reclaiming
The CR8000 reflow oven is equipped with a built-in high-efficiency flux filtration and reclaiming system designed to keep the oven tunnel clean while promoting easy maintenance and a healthier production environment. This integrated system effectively captures and filters flux residues during operation, reducing contamination inside the oven, extending service intervals, and improving overall process stability. By reclaiming and managing flux efficiently, the CR8000 helps maintain consistent performance, cleaner airflow, and a more environmentally friendly manufacturing operation.
Advanced Oven Control Software & System Safety
The CR8000'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.

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.
