A) Function:
The pcb runs
in automatically and is centered.
The grippers of the loading arm take the pcb on its upper edge (6
mm). The pcb is hold
by the grippers. The loading arm moves upwards to hang the pcb
into the clamps
of the dryer. Whilst hanging, the pcb passes the drying process
consisting of 4
heating zones and a separate cooling zone. On the outfeed the
second loading arm
moves upwards to take the pcbs off the clamps and put them on the
outfeed belt. |

The dryer has four heating zones.
When leaving the heating zones the temperature on the pcb is about
150°C (thermal cure)
After leaving the temperature goes down. The pcb is being supplied
with hot air
to prevent condensation. The pcb passes the cooling zone. The
temperature on the
pcb is slowly run down such as to make the pcb leaving the dryer
at about 30°C.
C) Advantages:
No

Special
clamp for thin pcb material 0.1-2.4 mm
Excellent
temperature distribution on pcb
No
condensation
Visualization

Temperature
control of each zone on both sides
No
buckling or distortions
Extendable
at any time
D) Options/
Alternatives:
1.
Double-track drying allows pcbs to be dried side by side
2. Shuttle
dryer – with additional infeed for screen printing pcbs
