Model 25/2, for alkaline solutions

The upgraded stripping equipment – 25/2 – in addition to an improved look, offers a very efficient operation, a sophisticated user-friendly automatic control, and very low both of water and electrical energy consumption.

Great attention was paid to the filtration of the stripped film by our designers: the efficient removal of the dissolved dry-film particles from the system is extremely important for a correct and economical operation of this process. The standard model is fitted with a rotating drum filter and a sloped slide, properly placed to convey the stripped dry-film into a basket, for easy disposal.The machine can also come complete with an optional cyclone filtration unit, which can further provide for an extremely advanced level of filtration; moreover the unit is particularly suitable to treat the residues of "formulated" stripping solutions.

The machine includes

• Anti-foam dosing systemstainles-steel-strip
• Regeneration system of the stripping solution
• Complete draining control and fully automatic filling system of the stripping chambers (the solution titre and the level are automatically obtained)
• PLC and dedicated software, developed in-house

This user-friendly equipment was designed for high flexibility and low operator intervention. All process parameters to be kept under control in order to optimise the machine operation are visualized and can be set on the liquid-crystal display: the titre of the concentrated solution, the percentage of the board surface to be stripped, the anti-foam cycle time, etc.

The first module includes

• Entry conveyor fitted with sensors monitoring the incoming boards and complete with an exhaust duct for connection to the fume aspiration system
• 1st stripping chamber (1635mm long – 2 off 7,5 HP pumps)
• Built-in rotating drum-filter for dry-film separation
• 2nd stripping chamber (430mm long – 1 off 5,5 HP pump)
• 3 rinsing sections (total 900mm long – 2 pumps rated 3 HP; 1 pump rated 1,5 HP)

The second module includes

• Drying section fitted with turbines and blowers, complete with air intake filter
• Air heating section for thorough drying of the boards
• Exit conveyor

Technical data

• Working width: 635mm
• Working height: 1000mm
• Adjustable conveyor speed: 0 - 3 mt/min
• Max board size: 635mm x infinite
• Min board size: 200mm x 250mm long

For alkaline dry-film and solder mask

Three models are available following length and number of developing chambers:

• Model 2/25: 2 developing chambers
  (mm 1135 + 430)
• Model 2/25/S: 2 developing chambers
  (mm 1635 + 430)
• Model 25/3: 3 developing chambers
  (mm 1635 + 1135 + 430)

The standard machine is supplied with

• anti-foam dosing system
• automatic regeneration system of the developing solution based on the continuous monitoring of alkalinity and conductivity levels in the chambers or, as an alternative, semiautomatic regeneration system of the developing solution based on the surface reading of the incoming boards
• complete draining control and fully automatic filling system of the developing chambers (the solution titre and level are automatically obtained)
• PLC and dedicated, in-house created software prearrangement for direct connection to ultrafiltration system
• The solution preset temperatures are consistently controlled by means of heaters and cooling coils (the latter can even be connected to an external refrigerating unit, on request)
• A maximum cycle time has been fixed and programmed in the PLC for every sequence and operation cycle in order to improve the process supervision and to prevent any major misfunction.

Etching module 

High rigidity construction, Pvc supporting structure and titanium components.

Including

• Etching chamber with 4 spraying sections (2 upper + 2 lower sections)
• Supporting titanium frame, providing for spraying manifold oscillation
• The oscillation of the manifolds is controlled by an inverter drive and can be adjusted with regards to the conveyor speed
• Automatic regeneration of the etching solution : the exhausted solution is drained while fresh solution is replenished by back cascade flow from the last "anti-pollution" section
• A dedicated densimeter,precise and reliable, complete with long life probes controls the regeneration process
• The spraying chamber is separate from the solution tank: very few ammonia vapours in case of service
• Moreover the side location of the solution tank prevents deformation of the spraying chamber.
