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" (430 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.

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.
