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.
Technische Einzelheiten
• HG lamps: HG high-pressure lamps are
required for industrial curing. These work with up to
20 bar due to gas expansion
• Arc tube: An electric arc is ignited via a
quartz glass arc tube containing mercury and
argon. The light has bandwidths with sharp
concentrations at certain frequencies
• Mercury vapor lamp: gas discharge lamp
• Stops the system: The appliance is equipped with a
differential pressure switch that stops the system immediately
if the ventilation falls below
the prescribed values.
• Width adjustment: electric and automatic
width adjustment
• Humidity control (optional): Air conditioner
(humidity and TºC control in a closed circuit)
Functions
Process monitoring
During the entire protection process
monitors the Programmed Logic
controller (PLC) controls the charging 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: Enables
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 over the course of time:
• Ozone pollution
• UV surface breakdown
• Temperature on airborne
Pollutants
Specifications for inline modules
• Control system: Instrument control
• The service life of the UV lamp can reach 1000-1200 hours
• Focus Design Import high light reflector lampshade
• Independent cooling area ensures low
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 vapor
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 off
a single area must be distributed
