IMO ECO 2000 PCB Cleaning Machine

The ECO 2000 can remove rosin-based fluxes, low-residue (no-clean) fluxes, and water-soluble fluxes. It also handles resin, flux mist, handling residues, and is suitable for cleaning assembled PCBs, small parts, paste–misprints, solder frames, and SMD stencils.

The ECO 2000 can clean PCBs up to 503 × 405 mm in size. It has a capacity of 170 Eurocard-sized boards when loaded with boards of 10 mm height.

It operates in three main steps:

• Cleaning with an alkaline / neutral cleaning agent.
• Several intensive rinse cycles using deionised (demineralised) water.
• Hot-air drying.
  The number, duration, and temperature of cleaning, rinsing, and drying steps are individually programmable via the machine interface.

The machine includes a demineralisation cartridge and conductivity monitoring to measure the purity of the final rinse water. Cleaning solutions, rinse parameters, and past cleaning logs can be viewed via the network interface. The last 20 cleaning cycles are retrievable in log form.

• Dimensions: approximately 97 cm high × 60 cm wide × 78 cm deep.
• Power: operates on 230V, 60Hz supply.
• It uses hot-air drying; noise, weight etc are in IMO spec.

• Cleaning period is approximately one hour.
• Drying period is also approximately one hour, depending on load and drying temperature settings.

• The ECO 2000 is easy to program with what we might call “recipe control” for cleaning, rinsing, drying (number of cycles, timing, temperature).
• Network interface for viewing programs and monitoring status.
• Automatic / optional detergent dosing in IMO’s design (according to IMO datasheet for ECO 1000/2000) which helps consistency.

• Cycle times are substantial; approx. two hours total (clean + dry), so throughput is limited compared to faster, continual flow systems.
• Energy consumption is non-trivial (hot water, spray, hot air drying). Facility power and ventilation may need consideration.
• Height limitation of boards (10 mm height for 170 Eurocards) – larger/heavier assemblies may require modified fixtures.
• Use of alkaline or neutral cleaning agents and hot air drying require maintenance of rinse water quality, filters, and demineralisation cartridge for optimal performance.
