Den-On Rework Systems
RD500 Series III
Designed for Standard or Lead Free Solders, Large or Small Boards, Large or Small Components.
Both the RD-500III and the RD-500SIII feature 700 watt upper and lower hot air heaters. By delivering hot air simultaneously from above and below, these units are able to evenly heat the component and solder connections.
Key Features of the RD-500 III System
High Performance 3 Point Heating System for Lead Free Rework
Upper Hot Air Heater ( 700W ) Lower Hot Air Heater ( 700W ) and Area Heater ( 1200W ) of RD-500SIII
Upper Hot Air Heater ( 700W ) Lower Hot Air Heater ( 700W ) and Area Heater ( 2400W ) of RD-500III
2 Point Cooling System
The RD-500III and RD-500SIII machines cool the component by two means. The primary method is by turning the heaters off after the heating profile and blowing air through the heating element. The second method is with a cooling fan. After the heating cycle is complete, the heater head raises about 50 millimeters from the board and a fan that is pointed at the reflow point is turned on.
Additional cooling such as this has shown to improve lead free solder connections.
This second cooling can be turned on by choosing an odd number in the Reflow Time. It is turned off by choosing an even number in the Reflow Time.
