The sequence of bathes is:
Bath 1: Cleaner Conditioner
Bath 2: Pre-Dip
Advice: First use the pre-dip solution
for cleaning of tank 3. Fill in the pre-
dip solution into tank 3 overnight and
after that re-use it to fill tank 2:
Bath 3: Catalyst
To stir the bath, always
use a very
clean glass or plastic rod that you rinse
in bath 2 - never in water.
Bath 4: Intensifier
Bath 5: spare bath
This spare bath can be used e.g. for our
electroless tin plating (SUR-Tin) at
room temperature. If not in use, please
fill the tank with plain water to avoid
deformation of the PVC walls.
Bath 6: Copper plating
Fix both anodes to the anode holders,
use anode bags to cover anodes and
use the strings to form a knod so that
the bags are kept in place. Make up the
copper bath as per the appending Bath
Setup instructions.
Anode preparation:
For proper copper plating results it is
necessary to run the anodes under wor-
king conditions but with reduced cur-
rent of 1 A/dm². For that reason fix a
clean and well brushed PCB of 200 x
300 mm in a board holder. Then mount
the holder onto the agitation rod and
screw it carefully. Start air agitation.
Start mechanical bath agitation. Adjust
agitation speed to about value 4 on the
scale. Activate rectifier and adjust a
current of 1 A / dm² : 2 sides x 6 dm² x
1 A / dm² = 12 A. Run the bath accor-
ding to items 8 to 12 of the Plating
System Step 5 instructions.
copper bath solution are then ready for
use.
Rinse section:
The Compacta ABC unit is equipped
with a water saving triple cascade rinse
section: two cascading rinsing tanks
with overflowf ollowed by one fresh
water spray rinse tank .
Pre-rinse always in the bath with the
highest water level followed by the
one with the lower level. Last rinsing
step is fresh water spray rinse (activa-
ted by foot switch). It is highly im-
portant to clean not only the PCB but
also the board holder with every rin-
sing step in order to avoid contaminati-
on of the following treatment bathes.
