Maximum Thermal Performance.
The OmniMax platform offers a combination of industry proven technologies in an easy to use, reliable and efficient reflow system for high-end production requirements. From lead-free to hybrid processing, the OmniMax 10 zone oven delivers high performance thermal processing. The OmniMax sets the standard in innovative technologies that save on lowest power and nitrogen consumption rates.
- Uses a dual IsoThermal chamber approach that produces ∆T’s less than ± 2°C within 7 and 10 zone ovens (air or nitrogen)
- Standard conveyor system supports a 20” (508 mm) process width
- 10 zone process capability and control
- Nitrogen replaces oxygen and provides greater profile flexibility and widens the process window
- Prevents oxidation of solderable surfaces (promotes wetting) and of the molten solder, allowing for reduction of void levels
- Stronger solder joints and shiny finish
The most powerful and Advanced Cleaner in the market.
Aqua Klean Systems introduces the Typhoon T-8 Chemistry Zero-Discharge Cleaner, a new way to clean RMA, No-Clean, and Water Soluble (OA) fluxes. The T-8 incorporates an adjustable chemical injection pump to assist in keeping chemical wash concentration consistent.
Equipped with 10 HP wash and rinse pumps, and two 15 HP turbine blowers, the Typhoon T15’s performance is unmatched.
Typhoon T-8 Chemistry Cleaner:
- Adjustable chemical injection pump for consistent concentration
- Dynamic air blow-off to allow water free chemical isolation
- Proprietary nozzle for correct flooding and impingement need to solubilize flux residues.
Typhoon T-15 Water Soluble Cleaner:
- Equipped with 10 HP wash and rinse pumps and two 15 HP turbine blowers (4 rinse sections and 2 dry sections)
- Fits boards up to 24″ wide
Advanced inspection machinery with outstanding defect coverage.
Vi Technology 5k SPECTRO:
- Capabilities include: presence, absence, polarity, placement accuracy, solder joint inspection
- Accurate tilt and coplanarity measurement of ICs, connectors, and passive components
- For post print, mixed mode, pre reflow, or post reflow applications
