Inline UV Mercury oven

The UV mercury oven for single-sided selective conformal coating of printed circuit boards (PCBs) maximizes productivity and yield, saves factory space and reduces PCB handling requirements.

The UV mercury oven is available for integration into the modular Protection Concept line and can be configured for the processing of printed circuit boards in a continuous process using the UV mercury curing method.

Technical details

• HG lamps: HG high-pressure lamps are
required for industrial curing. These work with up to
up to 20 bar due to gas expansion
– Arc tube: An electric arc is ignited via a quartz glass arc tube
quartz glass arc tube that contains mercury and argon.
argon. The light has bandwidths with sharp
concentrations at certain frequencies
– Mercury vapor lamp: gas discharge lamp
– Stops the system: The device is equipped
equipped with a differential pressure switch that
stops the system immediately if the ventilation falls
falls below the prescribed values
– Width adjustment: Electrical and automatic width adjustment
width adjustment
– Humidity control (optional): Air conditioning unit
(humidity and TºC control in closed circuit)

Functions

Process monitoring

During the entire protection process< 0 >
process, the Programmed Logic
control (PLC) monitors the loading and
the loading and unloading process,
position of the circuit board and exhaust air
Ventilation for possible solvent-based protection processes.

Ventilation concept

Unique ventilation design: Allows< 0 >
cooler operation of the oven and extends
the service life of the electronic components.

50% Of directed light

The reflector supplies over 50% of the
directed light. The efficiency is
more and more in the course of time:
– Contamination by ozone
– UV surface breakdown
– Temperature on airborne
pollutants

Specifications for inline modules

– Control system: Instrument control
– UV lamp life can reach 1000-1200 hours
– Focus design import high light reflector lampshade
– Independent cooling area ensures low temperature
temperature when PCB comes out
– The transmission system uses an adjustable speed of
100-2000mm/min

Details on hardness

– The luminosity of the lamp is proportional to the steam
temperature
– Electron arc temperatures with pressure increase
during the warm-up phase
– Ballast resistors required to prevent explosions
– High intensity light – cannot be low Light from
a single area must be distributed
