Forced air convection reflow oven

The RK41 is a very populair model. It fit perfectly in medium production lines. The RK series convection reflow soldering systems uses re-circulated hot air to accomplish reflow at much lower temperatures than IR systems. Using constant, even heating, a great variety of board sizes will reach reflow temperature with the same heat profile. By eliminating set-up time your production line can work to its fullest capacity. “Environment friendly” is more then just a catch to the RK designers. With reduced energy consumption and carefully controlled air-flow and exhaust systems, your plant will only benefit from its introduction.

Highlights:

• Suitable for single sided as well as double sided pcb’s.
• Easy processing through the 5.7″ LCD touchsreen with an intuative user interface
• Forced air convection provides uniform heating and prevents shadowing.
• 4 zones with maxium temperatures up to 300°C. Can be used for lead free soldering
• Optional cabinet available
• Visual inspection of reflow process through top glass



• Two detachable thermocouples for measuring substrate temperatures.
• Control by RS232 connection is available
• Exhaust pipe system included for oven, in- and output

▶ Product Feature

Forced air convection heat to maximum temperatures up to 300°C for lead free soldering. Forced air convection provides uniform heating and prevents shadowing.
Four heat zones, each independently controlled for accurate temperature profiles.
Bench-top unit can be converted to a stand-alone unit by use of the optional cabinet and also integrated into a fully conveyorized production line.
Viewing panel allows visual inspection of reflow process.
Detachable thermocouple for measuring substrate temperatures.

The RK41 convection reflow soldering systems uses re-circulated hot air to accomplish reflow at much lower temperatures than IR systems.
Using constant, even heating, a great variety of board sizes will reach reflow temperature with the same heat profile.
By eliminating set-up time your production line can work to its fullest capacity.

Convection heating provides many other advantages over IR.
In addition to the wide process window

it works with
No shadowing
No belt load sensivity
No cold solder joints
No colour sensitivity
No hot spots

▶ 4 zone temperature control
With a belt width of 360mm and consistent temperature across the entire width the RK can easily accommodate your entire production line speeds up to 0.6 meters/minute.

▶ Environment friendly
“Environment friendly” is more then just a catch to the RK designers.
With reduced energy consumption and carefully controlled air-flow and exhaust systems, your plant will only benefit from its introduction.
Ease of access to all parts of the machine ensures fast and easy maintenance.
Managing information is quickly available and ancillary processes, such as glue curing, are easily programmed.
The RK41 reflow system is built to last and to perform to the highest standards throughout its long lifetime.
