REHM RDS UV

Cure UV coatings reliably with innovative equipment from Rehm

Applying a protective coating improves the reliability and lifespan of your products. The coating improves your components’surface insulation resistance and protects electronic components from aggressive environmental influences. Rehm has developed an innovative UV dryer for curing all types of UV coating. Depending on the material requirement, the system is available with UV curing lamps with either medium-pressure mercury lamps or UV LED lamps. Thanks to its small and compact design, the system can be adapted to suit any production environment.

UV coatings can be hardened within just a matter of seconds. This shortens processing times, increases production speeds, and combines environmental with economic benefits. In addition, UV coatings also offer qualitative advantages, such as higher gloss levels and improved durability and scratch resistance on a coating surface. It is no wonder that UV coatings are becoming more frequently used in production by the electronics industry. Decreasing coating cycle times now require hardening times to be shorter. This can be achieved through the use of a UV curing system.

Rehm Thermal Systems has responded to this trend by developing the new RDS UV, a small and compact dryer designed specifically for hardening UV coatings and adhesives. UV coatings do not contain any solvents, which means that they are particularly easy to work with and environmentally friendly.

Unique technology advantage

  • Stable process for reliable results
  • Quick hardening within seconds
  • Optimal heat transfer and thermal stability
  • Can be confi gured with different types of light sources
  • Low energy consumption in standby mode
  • Low maintenance

Selective Conformal Coating with UV Dryer

Falling cycle times in the lacquering process necessitate shorter curing times which can be implemented ideally with the help of UV drying systems. UV lacquers permit curing within a matter of just seconds, assure short processing times and increased production rates, and they combine ecological and economic advantages.

Cold light source

Depending on the type of adhesive to be cured, the system can also be configured with UV LED arrays with integrated air-cooling for the LEDs. The UV LED arrays have an average lifespan of around 20,000 hours (the manufacturer guarantees a 10,000 hours lifespan). As a cold light source, the LED arrays are particularly suitable for use on sensitive materials.

  • Homogeneous distribution of light density
  • Stable light output at constant high levels, even when working distance varies
  • Encapsulation protects LEDs from dust and dirt
  • Low maintenance and replacement part costs
  • No warm-up time required and high availability

High-performance lamps in the RDS UV system dry all types of UV coating

The standard RDS UV system is equipped with mediumpressure undoped mercury lamps. The lamps have a power output of 120 W/cm and a lifespan of over 8,000 hours. The distance between the conveyor and the lamps can be freely adjusted from 50 mm to 100 mm.

  • High power desity
  • Suitable for continuous operation
  • Low energy consumption in standby mode
  • Quick start-up from standby mode

Reliable Transport

The standard RDS UV system is equipped with a pin-chain conveyor system. The conveyor system can be adjusted to suit your components, regardless of the geometry of circuit boards. The conveyor’s tracks and speed are also fully adjustable.

  • Secure, stable conveyor system
  • Adjustable conveyor height +/- 100 mm
  • Conveyor width 80 – 480 mm
  • Quick start-up from standby mode
