The Rota-Spray is constructed in PVC Plastic with welded seams and joints. This practice has been widely used throughout the Chemical Processing
Industry for many years. It is physically very strong and extremely resistant
to many corrosive chemicals. The only disadvantage with this technique, is that it make the construction hard and brittle.
Therefore extreme care should be taken when placing the unit on any surface.
When removing from packaging, ensure the unit is lifted evenly and gently and placed very gently on to a flat surface. Please avoid any heavy
The Rota-Spray is designed to use:-
1) Ferric Chloride to etch Copper, Brass and Stainless Steel
2) Ferric Nitrate to Etch Silver
3) Water Based Photoresist Developer to develop
If you wish to use any other Chemistry to process different materials, please contact
your Supplier for advise before proceeding.
Failure to do this may cause serious Damage and will invalidate the warranty
Instructions of Use
Set the temperature as required, 45ºC for etching. For standard 1 oz (35 micron)
copper – Time set to 90 seconds is recommended
Temperature control
The temperature controller is a microprocessor-based digital electronic regulator
used to control temperature with ON/OFF control of the heater. The liquid
temperature is displayed on a 2 digit red led display while the heater state is
indicated by a LED (OUT/SET).
When the unit is powered up ° C is displayed for ten seconds, then the temperature
of the liquid will be displayed. The heater will be activated if the liquid temperature
is below the set point. The factory pre-set is 45 °C.
Please note
the heater will not operate until the temperature is 3 °C below the set point.
If there is insufficient liquid in the tank the temperature display will not operate.
IMPORTANT
The maximum temperature that can be set is 50°C.
NO ATTEMPT SHOULD BE MADE TO INCRESE THE TEMPERATURE BEYOND
50°C, AS THIS WOULD CAUSE SERIOUS DAMAGE TO THE UNIT AND
INVALIDATE ANY WARRANTY
PLEASE DO NOT LEAVE THIS UNIT UNATTENDED WHEN IN USE
Photoresist coatings.
PLEASE READ THIS VERY IMPORTANT NOTICE
– If the unit reaches set point and is then turned off and on again
