Etching Machines for Printed Circuit Board

  • Working area 220x280mm
  • Tank capacity 2 litres
  • Built-in pump
  • Heater with thermostat 100W
  • Supply 220V
Bubble etch system
It allows to obtain good results in short time (3:7 min.).

Completely anti-acid PVC made.
The machine is equipped with a transparent cover which enables a continuous control of etching feeding.

A built-in pump produces a great quantity of bubbles which removes the copper from the boards.
A heater with thermostat assures the optimal temperature of the ferric chloride.


Completely anti.-acid PVC made it allows the treatment of single and double side boards.
When only single side boards have to be etched, they could be put back-to-back so as to double the working area.
The machine it equipped with a magnetic dragging pump which does need no maintenance.
In this type of pump the acid never get in touch with the metallic part of the pump, this allows to use any type of acid for printed circuits between the common ones present on the market.
Floating nozzles during their movement provide an uniform distribution on all the surface to be treated.
The horizontal position of the boards has been choose in order to avoid the phenomena of the over-etching which is present in the machine which treat the boards in vertical position.
This phenomena happens because in this case the lower part of the boards is reached by the spray of the nozzles and by the acid which runs down the same boards.
The heating element is quartz made and allows a high safety degree against breaking if acid is added when the machine has already reached the temperature.
An adjustable thermostat placed on the control panel enables to choose the suitable temperature, while the thermometer placed on the same panel allows a continuous monitoring of the reached temperature.
A timer enables to set the etching time.
When this time is reached the timer stops the pump and the nozzle movement, remain inserted the heating element so as the machine remain in temperature.
The machine is equipped with a
transparent cover which enables a
continuous control of etching feeding.
A safety switch on the cover stops the process when the cover is open in order to avoid spray of acid.
On the rear side of the machine there is an outlet for the external vapour drain while a useful clock allows quickly emptying of the tank containing the acid.

This machine has been designed to satisfy the needs of the middle productions.
Realised with the same standard used for the industrial machines it allows to obtain printed circuits, ready to be drilled in few minutes.
Its operation is very simple: a boards has to be inserted into the machine (keep attention that it has to be well expanded); the lower roller will move the board to the etching chamber where 12 spray nozzles remove the copper.
The etched boards will then moved to the washing chamber where it will be washed by means of other nozzles.

Technical characteristics:
  • Realised completely in PVC
  • PVC roller with soft coating and titanium core
  • Double side etching chamber 480mm length
  • Maximum area of the boards 410x infinite mm length
  • Minimum are of the boards 40x40mm length
  • Tank capacity 15 litres
  • External dimensions 550 x 1200 x 1200h cm.
  • Magnetic dragging pump 65 lt./m 220V 50Hz
  • Heating 800W titanium with digital thermostat
  • Titanium core for the dragging of the roller
  • Level switch which stops pump and resistance in absence of liquid
  • Safety microswitch on covers
  • Dragging rollers speed adjustable 0 to 120cm/min
  • DC motor with tachometric dynamo with ON-OFF switch
  • Supply 220V /24 auxiliaries
  • Absorption max. 1000W
