PCB Processing Tanks
These small PCB processing tanks which are used with great success in both Industry and Education for Bare Circuit Board processing and Metal Etching. The successful proven design features self contained units each of which are free standing and will accept panels up to 320 x 260mm (12.6″ x 10.23″). Each unit is formed in two parts, the high density polypropylene inside tank being injection moulded as a single piece. This method of construction has proved to be far more efficient than the old method of welding together several vacuum formed parts which by design gives inherent danger of leaks from joins. This one piece design is an important safety feature which should be considered when choosing PCB tanks.
This inside tank has an integral top surround, which secures over the second of the two parts, an outer made from 6mm Polypropylene. A splash proof lid with full length board holder mesh covers a working area of 5 litre capacity. The board holders feature yellow side clips which can be secured to close the sides of the mesh when very small boards are being processed. For added safety the inside tank is bolted to the outer case at the bottom of the unit. This must be removed before access to electrical components. Where applicable, the specially developed 500 watt heater with protective silica sheath is externally mounted in the tank, as is the thermostat sensor.
The heater is fitted with an internal re-settable safety device to protect the tank if it is inadvertently turned on without any liquid in. All splash proof electrical controls including a variable thermostat setting are located in a recessed panel on the case front, which prevents liquid getting in contact with the electrics. We also recommend that all tanks are used with a RCD power break device. All the PA series tanks are designed to be modular.
PA104 10” x 12” Bubble Etch Tank
This, single tank, includes the heater and thermostat sensor as described above and has a pump fitted which forces air through two bubble bars to provide efficient and even etching. Illuminated switches control mains power and the pump whilst a neon indicates heater operation. The switches and neon have splash proof covers. The temperature is set by adjusting the variable thermostat control knob. (Optimum temperature for Ferric Chloride 40 – 45 °C). The tank is supplied with a syphon, socket and 2 metres mains lead.
