Etching Device 1 and 2

... for prototyping and small batch production of printed circuit boards

Etching Device 1

Etching Device 2

Etching Devices 1 and 2 are used in laboratories and small batch production for making printed
circuit boards as well as for etching metal folies.
The cuvettes are out of cristal clear acrylic glass. They are mounted at a plastic tube in which the
membrane pump is mounted. Further the etching device includes the glass heater for heating up
the etchand temperature up to 45°C, a PCB-holder for carrying the printed circuit boards while
etching and a thermometer.
During etching the boards, the membrane pump blows air in the air curtain tube which is mounted
at the bottom of the tank. Outcome of this, small air bubbles are inside the etchand and reduces the
etching time.

GEFAHR!

1. Start-up

1.1 Placement

The etching device will be delivered mounted completely. Only the glass
heater and the thermometer has to plug in into the holes at the top of the tank.
Place the etching device into the catch basin. Place the device on a horizontal,
stable and acid-proof basis (e. g. tiled table).

The working area should be ventilatable and well illuminated!

1.2 Assembly

1. Place the etching device into the catch
basin (1). Place the device on a
horizontal, stable and acid-proof basis.

2. Plug in the glass heater(2) into the hole,
top of the tank

3. Fill water into the tank (4) (see technical
data). Please note: The water level
should about 2-3 cm below the maximum
high of the cuvette.

4. Connect the membrane pump (5) to
power supply (AC 230V /50-60Hz).
Please check, if small air bubbles are
comming out of the air cusion tube (3),
which is laying inside the glass acrylic
tank.

5. Thermometer (6)

6. Board holder (7)

7. Safety valve (8)

1.3 Handling of the board holder

You can adjust the board holder by
loosening the screws (8) below the handle
strip.
In case of one-sided boards, you can double
the holding capacity by clambing the boards
back-to-back.

If you do not tighten the screws, you can also shift the strips without
having to operate the screws.
For larger boards, remove the middle strip.

1.4 Etching bath

For etching, we recommend only our sodium persulfate. This etching mediums
is odorless, clear, and pollutes the device only insignificantly.
Further sodium persulfate has the positive feature to get blue if solution is
saturated.
It achives etching times of 6-8 minutes at 40-45°C. The etching speed lies
between 4 and 7 µm/min with a copper reception of approx.: 30g/l. The batch
amount ist 200 - 250 g/l of water.

- Unplug all mains plugs before filling in the etching sulfate.

- Fill water into the tanks (see technical data) and then pour the etching
sulfate into the water.

- Place the borad holder into the tank as a cover

- Connect the membrane pump and the glass heater to mains again.

In case of using other etching chemicals, we can not take over any
guarantee for the function of the device since these chemicals may
disolve the glue of the glass cuvette.

1.5 Adjusting the heating regulator

1. Switch-on the glass heater only when the tank is filled
and the pump is activated!

2. The water level should be a few millimeters
above the marking of the heating rod so the
heater regulation can work correctly.

3. Do not heat the bath to a temperature above 50°C
since this can cause a deformation of the acrylic
tank and a malfunctioning of the thermometer.

4. Connect the power cord of the glass heater to mains

voltage (AC 230V/50-60Hz). Turning the adjustment
knob in plus-direction increases the temperature, the
temperature is reduced by turning into the minus

direction

5. To adjust the temperature please turn the knob to
maximum (+).

Control temperature rise while heating up. When Temperature of 45°C is
reached, turn adjustment knob slowly in direction (-) until the indicator lamp
ist deactivated and the glass heater is OFF.

ATTENTION!

Pay attention to the temperature of
etching bath. Temperaure higher than
+50°C may result in deformation of
the acrylic tank and may damage the
glass heater.

2. Etching procedure

1. Switch-on the membrane pump by connecting the feeder to mains voltage.

2. Plug in the power cord f the heater to mains voltage. When bath

temperature of 45°C is reached you can start etching.

3. Clamp the board in the board holder and make sure, that the board is fixed

well.

At skin contact, rinse immediately
with lukewarm water and soap.

4. Immerse the board holder with the board into the tank.

5. After 5 to 10 minutes, the copper is removed.

6 Rinse the printed circuit board in water and dry the board

ATTENTION

Please notice:

The bath is saturated if the color of the liquid changes to a deep blue and

the etching times extend to more than 30 minutes. It has to be renewed.

The etching device is designed for
using sodium persulfat.
Don`t fill in iron-III-chloride or other
chemicals!

The etching liquid can remain in the cuvette without losing it´s effect for a

few days. Liquid losses due to evaporation can be compensated using
water.

If you don´t want to use the etching
device of a longer time, please
discharge the tank. Fill the etching
fluid in a plastic canister and store
them out of range of children and
foods.
After this fill water (approx.: 1l) in the
tank and switch on the membrane
pump for a few minutes to clean the
air curtain tube.

ACHTUNG!

According the water law of Germany
(BGBI (186/1996) dated 19.04.1996),
the remainder content of copper is
limited to 0,5mg/l that may be
delivered to the drainage.
Because of new limits appointed by
the goverment, it is suitable to inquire
corresponding information of the
appropriate government agencies.

ATTENTION

Before cleaning the air curtain tube,
switch-off the glass heater.

3. Abwasserbeseitigung

Zum Ablassen der Ätzflüssigkeit (gesättigte Lösung oder bei längerer Nicht­Nutzung des Ätzbades) stecken Sie den mitgelieferten PVC-Rohrstück in die
dafür vorgesehene Bohrung auf der dem Pumpengehäuse entgegengesetzten
Seite der Ätzküvette.
Verwenden Sie als Sammelbehälter ausschließlich verschließbare PVC-oder
Glasflaschen.

Bei der gesättigten Ätzlösung handelt es sich um Sonderabfall (Trichlorethan),
den Sie nach den örtlich geltenden Bestimmungen entsorgen müssen.

Ätzflüssigkeiten unbedingt außerhalb der Reichweite von Kindern

aufbewahren!

4. Maintenance and cleaning

lAccording to the application frequency, you should regularly clean the

etching device in order to guarantee a perfect working. This specially affects
the part pump, connecting tube, board holder etc.

Use only plastic container for storage
etching fluid.

Make sure that no etching fluid get
inside the safety valve. Running back
etching medium destroys the
maembrane pump.

Not required tools, equipment and
parts take away from working area.
Switch-off the device after use.
Cover the cuvette with the board
holder.

Zur Erhöhung der Betriebsbereitschaft sollten Sie das Ätzgerät - je nach

Einsatzhäufigkeit - reinigen. Besonders pflegeintensive Bauteile sind der
Luftverteilerschlauch, die Luftschläuche, die Pumpe und den Platinenhalter.

Zur Grundreinigung entleeren Sie die Ätzküvette über das aufgesteckte
Ablaufrohr und füllen Sie ca. 0,5l Brauchwasser in die Küvette. Schalten Sie
nun die Pumpe ein.

Achten Sie darauf dass die Heizung nicht eingeschaltet ist!

Durch das Einblasen von Luft werden die Poren des hochporösen
Luftschlauches weitgehend gereinigt. Falls sich Poren durch Ätzkristalle
verstopft haben können Sie versuchen, vorsichtig mit einer kleinen Holz/PVC­Leiste über den Luftschlauch zu streichen und damit die Kristalle zu entfernen.

Das Reinigen der Ätzküvette erfolgt ebenfalls über einer Holz- oder PVC­Leiste die mit einem Schaumstoff (z. B. Tesa Moll) beklebt ist.

Bei Nichtgebrauch des Ätzgerätes ist es trotz Rückschlagventeil sinnvoll, den
Anschlussschlauch von dem/den Ventil(en) zu lösen. So ist eine
