The EXP 8000 is a high speed double sided exposure machine mainly designed for industrial production and equipped with two 4000 W mercury halide lamps. These lamps in about 900 mm distance from the PCB ensure almost parallel light.
Operation
EXP 8000 guarantees a perfect exposure within a minimum of time and energy consumption by two UV sensors. The required exposure energy is preset on a keyboard and shown on a digital readout. The two intelligent UV-light emission controllers (one per side) automatically measure the energy supplied per side and stop the exposure at preset energy amount. A vacuum pump provides a close and uniform contact between artwork and board. The exposure cycle starts when the drawer is pushed in. At that moment the lamp shutters are opened and the lamp’s powersupply is increased from stand-by to full power. In stand-by mode, the energy is reduced to 25% in order to save energy and avoid heat problems. The machines have powerful cooling fans. When the exposure is fi nished the vacuum is stopped.
