Exposure process for printed circuit boards (PCBs)

Belichtungsverfahren für Leiterplatten

 

Situation:

In case of power failure, safety standards require that
the carriage with the PCBs on top have to stop.

 

Problem:

In case of power failure, the PCBs run against the stop and cause a crash. The recalibration and
readjustment are very complex and expensive.

 

 

 

 

 

Intention:

Controlled Stop of the machine in case of power failure

thus avoidance of a crash.

 

 

Solution:

> Use of DEV2.0 via "Plug&Play": 
   Supplying the drives with the energy that is 
   necessary for a controlled stop

Use of NEV to supply the 24V power grid 
   for controls and sensorics

 

Results:

1. Controlled stop of the machine in case of power failure
2. Prevention of a crash and mechanical damage
3. No recovery time
