CR-4000C Features
- Four independent topside heat zones with high-mass convection heat sources
- Two lower convection heat zones
- PID temperature control settings to 300°C for lead-free reflow
- 400mm (16") pin conveyor over 500mm (20") stainless steel mesh belt & pin conveyor
- Computer controlled, with password-protected software access
- Three thermocouple inputs for advanced temperature profiling and thermal management functions
- A full-function oven at a space-saving 2000mm (just over 6 ½ ft.) length
The CR-400OC is a perfect fit for those assemblers who want a compact medium-volume lead-free reflow with many of the profiling and performance characteristics of larger ovens. Their obvious choice should be the CR-4000C because except for size, energy usage and price – which are much lower -- it matches many big oven assets feature for feature. It has a combination stainless steel mesh belt & pin conveyor with a board-heating width of 500 mm (20") and a double-sided board processing capability. Also part of the package is an on-board computer with Windows®-based password-protected software to permit on-screen profiling that sets oven parameters
Automatic oiler for pin conveyor is software driven for ideal preventive
Power-lift hood is software controlled.
Maximum Functionality, Ease-of-Use, and Trouble-Free Maintenance Are
Not Sacrificed by the CR-4000C Compact Design
While high mass heat sources and a unique air flow design allow efficient convection reflow over shorter heated lengths, great care has been taken to ensure that the CR-4000C compact design does not come at the expense of easy access to system components for regular operation and system maintenance. Lockable access panels, air-cylinder-assisted hinged covers, and an automatic heating chamber hood lift, complement a well thought-out and organized system architecture within a small footprint.
Automatic Hood-Lift Mechanism Allows Easy Access to Heating Chamber and Conveyor System for Cleaning and Maintenance
This photo shows the interior of the heating chamber with the hood in the raised position and the bottom of the air diffuser panels of the upper heating zones. It also shows the combination mesh belt and adjustable pin-type conveyor rails above the belt. The rail at the center of the conveyor in this photo is the movable rail and is adjustable for board widths from 2" through 17.7" on the CR-4000C system. An optional center board support system is also offered to avert board warpage issues common to larger PCBs processed at higher lead-free temperatures.
Zone Temperatures and Conveyor Speed are Easily Set Through a Password-Protected Parameters Window
Process control parameters that produce a specific temperature profile can be saved to and loaded from memory for specific production runs. once loaded, specific zone temperature settings, upper and lower limits, alarm settings and conveyor speeds can be adjusted as necessary. Password protection separates basic operator functions from critical parameter settings that should only be changed by supervisors or production managers.
Full-Screen Temperature Profile Recording
The CR Series control software allows easy charting of real-time thermal data from up to three separate thermocouple inputs for precise profiling that matches solder paste manufacturers' critical lead-free reflow parameters. This allows users to set zone temperatures and conveyor speeds to the optimum settings that will produce the desired profile at the desired throughput. The thermocouples also allow monitoring of temperature sensitive components at specific locations on the PCB.
