Cybersolv C8508

Cybersolv C8508CYBERSOLV® C8508 is the latest generation spray cleaner for reflow ovens and general equipment maintenance cleaning. C8508 has been tested on the toughest baked on flux residues with great success and has proven effective on the latest lead free flux.

Cybersolv C8508 is a non-flammable solvent maintenance cleaning fluid designed to remove flux residues from reflow oven surfaces, wave soldering fingers and pallets. Metal spring loaded fingers are used to hold and track printed circuit boards over a solder bath during the wave soldering process. Prior to soldering, liquid fluxes are applied to the bottom side of the circuit board using foaming and spray application methods. Overspray from the liquid fluxes adheres to wave fingers and pallets. Over time, the over spray flux must be cleaned.

Cybersolv C8508 solvency make-up is engineered with a mixture of oxygenated solvents and water. The solvents are specifically selected based on their affinity for rosin, no-clean and water soluble wave solder flux residues. Wave soldering machines are equipped with a fluid chamber and brushes to removed flux residues following the soldering process. C8508 is used full strength. The composition dissolves the flux residues and dries evenly without the need for a rinse.

Cybersolv C8508 is also effective at cleaning wave soldering pallets. The product is designed to be full strength in immersion systems using spray-under-immersion or ultrasonic agitation. The product is effective at ambient temperatures. If the residues are burnt or charred, heating the solution to 50-60°C improves cleaning performance. Following the cleaning step, the pallets should be rinsed with DI water and dried.

Cybersolv C8544

Cybersolv C8544Cybersolv® C8544 is a solvent cleaner and stripper designed to be used in immersion and manual cleaning applications. Easy to use, C8544 is applied as received and heated in a well-ventilated tank.

Cybersolv C8622

Cybersolv C8622Cybersolv® C8622 is a full strength solvent blend specifically designed as an IPA alternative in stencil wiping and manual bench top cleaning applications. Easy to use, C8622 is applied in applications where IPA is typically used.

Cybersolv C8622 is designed to replace IPA (isopropyl alcohol) for cleaning water soluble and rosin flux residues. C8622 is ideal for use at electronic assembly work benches, spot cleaning, under-stencil printer cleaning and manual stencil cleaning processes.

Cybersolv C8622 solvency make-up is engineered with a mixture of oxygenated solvents and water. The selected solvents are based on their chemical properties to mix with water. The mixture of ingredients forms an azeotrope, which provides for uniform evaporation. Uniform evaporation allows for the stencil cleaning agent to function as a solvent. The cleaning mixture forms a constant boiling and evaporation point.

Cybersolv C8622 is ideally suited for dissolving un-reflowed solder paste during the stencil printing process. C8622 improves stencil printing yields by removing trace solder paste deposits from the stencil aperture. Clean stencils are critically important when high dense stencil patterns. When cleaning the underside of the stencil with Cybersolv C8622, yield improves due to the repeatability of printing the right amount of solder paste printed onto fine pitch leads. Properly cleaned stencils achieve repeatability and reproducibility over time.

Cybersolv C8622 is also used in wipes and with manual ultrasonic stencil cleaning systems. C8622 rapidly dissolves the flux within the solder powder. Dissolving the flux allows the solder powder to release from the stencil aperture. Cybersolv C8622 dries spot free and does not require a water rinsing step.

Cybersolv C8882

Cybersolv C8882Cybersolv® C8882 is a fast-acting stencil cleaning solvent designed for the understencil wipe process. Cybersolv C8882 instantly dissolves all flux types within the solder paste, including water soluble, rosin and low residue no-clean fluxes.

Cybersolv C8882 is a solvent-based stencil cleaning fluid specifically designed to clean wet solder paste, SMT adhesive and flux residue from stencils (conventional and plastic pump), mis-printed PCBs, wave soldering pallets and tools, fixtures and squeegees. Cybersolv C8882 dissolves the flux vehicle, which allows solder balls to release from the stencil during the stencil printer wipe sequence. Cybersolv C8882 has a flash point over 60°C and evaporates cleanly from the stencil.

Cybersolv C8882 is effective for use within the following stencil cleaning processes:

  • Understencil Wipe Cleaning – Solvates the flux resin compositions within uncured solder pastes. Effectively cleans and removes solder paste that has a tendency to stick to the aperture walls and bottom of the stencil. Following the wipe process, a dry wipe and vacuum process rapidly dry the stencil following the cleaning process.
  • Hand-wipe, Immersion Stencil and Pallet Cleaning – The selection of solvents used in Cybersolv C8882 effectively remove polar and non-polar soils. Cybersolv C8882 can be used to hand-wipe a stencil following the printing process.
  • Semi-Manual Ultrasonic Stencil Cleaning Systems – Cybersolv C8882 is an effective cleaning agent for use with the GEN3 and SAWA ultrasonic absorption mat stencil cleaning systems.
  • Solvent Stencil Cleaning Spray Systems – Cybersolv C8882 is designed to run in solvent spray-under- immersion and spray-in-air cleaning machines that were commonly designed to clean with IPA. Cybersolv C8882 effectively washes and rinses the stencil.

For optimal stencil cleaning performance, Cybersolv C8882 should be processed “as is” at 100% concentration at ambient temperatures. Cybersolv C8882 wets and rapidly dissolves the flux that holds the solder spheres into a paste. Upon dissolution of the flux, solder balls release from the apertures and drop to the bottom of the cleaning tank. In well-designed stencil cleaning equipment, the solder balls are caught in recirculation filters, greatly extending bath life.

Cybersolv C8882 has no ozone depleting or global warming potential and is non-hazardous. Furthermore, this product does not contain substances prohibited by EU Directive 2011/65/EU, Restriction of Hazardous Substance Directive (RoHS).  Please reference the Cybersolv C8882 Safety Data Sheet for other safety and/or performance considerations.
