PCB Processing Tanks

Mega is the leading manufacturer of small PCB processing tanks which are used with great success in both Industry and Education. The successful proven design features self contained units each of which are free standing and will accept boards 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 using our CNC machine and advanced plastic welding techniques. 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, the following being an ideal processing sequence:

Develop - Spray Wash - Etch - Spray Wash - Resist Strip - Spray Wash - Immerse Tin

PA103 Spray Wash 

This tank contains two spray wash bars at the top, driven from a single mains water inlet, between which the developed, etched stripped or tinned board can be suspended to be rinsed. A bottom tube permits used water to be run off to waste. Width 180mm, Depth 525mm, Height 380mm.

PA104 10” x 12” Bubble Etch Tank

This, the most popular of single tanks, 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, IEC socket and 2 metres mains lead with moulded 13amp plug. Width 180mm, Depth 525mm, Height 380mm.

PA104 12” x 18” Bubble Etch Tank

Similar to the 10” x 12” model but with a deeper tank to enable 12” x 18” boards to be processed. Just like the smaller tank it includes a 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, IEC socket and 2 metres mains lead with moulded 13amp plug. Width 288mm, Depth 495mm, Height 650mm. The footprint is 288 x 495mm but with the ‘over-hang’ the length is 615mm.

PA207 Two-Tank Unit

Develop, Strip or Tin and Wash

A cost effective improvement over the standard PA107 Universal Tank. This unit includes a process tank as above plus an integral spray wash tank. The spray wash tank is solenoid operated with all electrical controls located on the front panel. Connections are provided at the rear for drain and cold water requirements. The integral spray wash tank offers safer, cleaner and more efficient processing of boards than the standard Universal Tank and being wider also gives greater stability. Complete with an IEC socket and supplied with 2 metres mains cable with moulded 13amp plug and a syphon. Width 275mm, Depth 525mm, Height 380mm.

PA210 Two-Tank Unit

Etch and Wash

An improvement over a standard Bubble Etch Tank. This unit is the same as the PA104 Bubble Etch Tank with the addition of an integral spray wash tank. The spray wash is solenoid operated and all electrical controls are on the front panel. Connections are provided at the rear for drain and cold water requirements. The integral spray wash tank offers safer and more efficient etching of boards than a standard bubble etch tank and being wider also gives greater stability. Complete with an IEC socket and supplied with 2 metres mains cable with moulded 13amp plug and a syphon. Width 275mm, Depth 525mm, Height 380mm.

PA310 Tri-Tank Unit

Develop, Wash and Etch

Our best selling and most popular PCB processing unit. A self-contained triple process unit with built-in DEVELOP / SPRAY WASH / BUBBLE ETCH functions providing a convenient bench standing system. The PA310 eliminates the normal untidiness associated with producing PCBs to the solderable-etched stage. A RESIST STRIP / SPRAY WASH / IMMERSE TIN combination can be added to provide a full PCB processing run. Function tanks and splash proof controls are as standard, with all electrics brought together on the recessed front panel. The connections are provided at the rear for drain and cold water requirements. Complete with IEC socket, 2 metre mains cable with moulded 13amp plug and two syphons. Width 400mm, Depth 525mm, Height 380mm.
