Full-Scale Performance in a Compact Design
The CR4000C reflow oven delivers feature-for-feature performance comparable to larger systems while reducing floor space requirements, energy consumption, and upfront investment. Unlike many compact ovens that rel on infrared heating, the CR4000C uses true hot air forced-convection technology to achieve superior and consistent thermal results. This advanced heating method provides exceptional edge-to-edge temperature uniformity of ±2°C, ensuring reliable, repeatable reflow performance across every assembly.
Flexible, Precision Conveyor System
The CR4000C is equipped with a combination edge/pin conveyor over a stainless steel mesh, accommodating assemblies up to 16" (400 mm) wide. This versatile design offers maximum board-handling flexibility and supports double-sided PCB processing.
Smart Automation for Ease and Reliability
Standard features of the CR4000C are designed to simplify operation while maximizing reliability and long-term performance. These include software-controlled automatic pin-chain lubrication for consistent, preventative maintenance, pushbutton motorized width adjustment for fast and precise setup changes, and a motorized hood opening that improves accessibility and serviceability. Together, these intelligent automation features reduce operator effort, minimize downtime, and help ensure consistent, dependable operation over the life of the system.
Energy-Efficient, Precise Thermal Control
The CR4000C is an energy-efficient, environmentally friendly 6 ½-ft reflow oven that consumes just 5-8 kW of power, even when operating at lead-free soldering temperatures up to 300°C. Standard features include three thermocouple inputs for accurate temperature profiling and thermal management, along with four independently controlled forced hot air convection zones using high-mass heating panels and two bottom-side convection zones, providing a total heating length of 52" (1320 mm) for consistent, repeatable results. Timed startup and shutdown functions enable coordinated warm-up and cooldown across multiple shifts, helping optimize production readiness while reducing energy consumption.

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.
