Advanced Features Made Standard

The CR-4000C reflow oven matches the capabilities of larger ovens feature-for-feature while saving you in space, energy usage, and money. The conveyor system features a stainless steel mesh belt with a board-heating width of 20” (500 mm) and a conveyor that can handle assemblies up to 16” (400 mm) wide. This combination conveyor provides you with maximum board handling flexibility and double-sided board processing capability. The pin conveyor’s automatic oiler is software-driven for optimal preventative maintenance and automatic pin conveyor width adjustment based on specific reflow program parameter settings is offered as a possible option.

Real-Time Temperature Profiling and Profile Prediction

The CR-4000C’s onboard computer comes pre-loaded with built-in Windows-based password-protected software, permitting on-screen profiling that sets oven parameters automatically, thanks to the partnered KIC Auto Focus profile prediction software. Thermal data from up to 3 separate thermocouple inputs can be charted on screen in real time.

Your control parameters produce a specific temperature profile that can be saved and loaded from memory for specific production runs. Once loaded up, settings including specific zone temperatures, upper and lower limits, alarms, and conveyor speeds can be adjusted per your specifications. Password protection keeps basic operator functions separate from critical parameter settings that should only be altered by supervisors or production managers.

Low Energy Consumption and Reliable Results

Your CR-4000C’s 4 independently controlled, forced hot-air convection zones of high-mass heating panels and 2 bottom-side convection zones, which span a total heating length of 52” (1320 mm) will provide you with reliable, easily replicated results. 3 thermocouple inputs are also standard on the unit for temperature profiling and thermal management.

This energy-efficient, environmentally friendly 6 ½’ unit consumes only 5-8 kW of electricity, even when ramped up to lead-free soldering temperatures of 300°C.

Timed startup and shutdown functions allow you to coordinate warm-up and cooldown times with production breaks and transitions between 3 separate shifts in each 24-hour period, promoting production preparedness and energy savings.

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.
