ATTENTION: rinsing water has to be
treated with an antipollution unit such
as our IONEX system. You must fol-
low your local waste water standards.
Rectifier:
The rectifier has a separate on / off
switch. Current and voltage are preset
manually by potentiometer and read
out by analog current and voltage dis-
plays.
The rectifier offers constant current
and constant voltage supply. For use
with ABC chemnistry we only need
constant current supply. For that rea-
son adjust the voltage (unloaded) to
approx. 2 V.
Then adjust current according to PCB
surface in use. Standard working cur-
rent setting is 3 A/dm². Example:
Board size 200 x 300mm = 6 dm², 3
A / dm² x 2 sides at 6 dm² = 3 x 2 x 6=
36 A.
Through Hole Plating process se-
quence
1. Cut your PCB to size with our board
cutter NE-CUT ensuring that the blank
size is about 20 mm larger than the
required PCB size.
2. Drill your blank board to the requi-
red hole pattern by using our
BUNGARD CCD or similar. Note: al-
low + 0,05 to + 0,1mm extra diameter
for the drill bits because copper plating
in the holes will reduce the effective
diameter.
After that use one of our brushing ma-
chines (RBM series) for scrub clean-
ing, washing and drying (if no bru-
shing machine available, brush and
clean manually).
3. Fix the cleaned and deburred board
in the COMPACTA 3-finger board-
holder and fix it on the leftmost con-
veyour arm (bath1). Turn on the switch
for the conveyor. Process the board in
the bathes 1 to 4 and 6 from the left to
the right, in the sequence and with the
timings from the enclosed Process
Flow Table.
A step indication of "R" in this Flow
Table means a rinse step, consisting of
a static rinse in each of the two cascade
rinse tanks and a subsequent spray rin-
se.
The aim of bath 2, the Pre-Dip, is to
protect the expensive catalyst in bath 3
from intrusion of both other chemicals
and rinse water. That is why you must
not rinse after Pre-Dip but you have to
go directly to the following bath 3!
