Chemtronics manufactures a wide range electronic cleaners.  From clean room cleaning supplies to production quantity flux removal or even blasting derbies from sensitive electronics with compression dusters we are your one-stop shop for the care of your electronic equipment.

Chemtronics® dusters are microscopically clean, oil and moisture free sources of "canned air" developed for applications where safe, ultra-pure cleaning is required.  Compact and portable, Chemtronics dusters deliver powerful jet action to instantly remove particles from even the most inaccessible areas.  Ultrajet® Dusters economize solvent usage by removing layers of dry particulate allowing the solvent to work immediately on encrusted soils. Ultrajet Dusters also accelerate surface drying when using slow evaporating cleaners.

Flux removal is critical to ensure reliable circuitry. Not only unsightly, some flux residue can promote short circuits and corrosion, degrading or destroying the printed circuit board. The type of flux to be removed, solvent compatibility and ease of application are all factors to consider when choosing a flux remover or electronic cleaner. Flux-Off® Flux Removers are specially formulated to remove all types of lead-free, rosin (types R, RA, and RMA), no-clean, water-soluble and synthetic (type SA) flux.

Electro-Wash® Cleaner Degreasers are engineered to clean a wide variety of soil, oil, grease, oxides and handling contamination, from equipment and assemblies.

Chemtronics Swabs and Applicators are engineered for use in a variety of environments and applications. They are ideal for use with our cleaner degreasers, head cleaners, flux removers and other solvents for fast, precision cleaning. From the innovative no-lint Chamois Tips Swab to the general purpose Cottontips Swab, Chemtronics has the right swab or applicator for your job.

FAQ's

Are swabs available for cleaning static sensitive electronics?

Yes, Chemtronics offers a full line of ESD swabs. They include foam, knit polyester, or knit microfiber heads with static dissipative handles. The proprietary handle material has surface resistivity of 1.0 x 10_10 ohms/sq, and will dissipate 99% of (5 kV) charge in 0.5 seconds. This avoids static generation, and can dissipate a charge when the user is grounded.

Is air duster (canned air) safe on my computer and other electronics?

Yes, air duster is generally designed for use on electronics. There are a few things to watch out for: 1) avoid spraying the refrigerant liquid, which can happen if you shake the can, or angle it too much. The refrigerant is very cold, so can damage some sensitive electronics. 2) Avoid cheap retail dusters that contain bitterant. Many retail dusters have bitterant added to prevent huffing. When duster is used in the home, there is concern that the material will be purposely inhaled (called “huffing” or “dusting”) by minors, which can sometimes lead to tragic consequences. To avoid this, bitterant is added to make the duster taste bad. This same bitterant can lead to unwanted and potentially harmful residues on sensitive surfaces like electronic circuit boards.

Why is there white residue when I clean my PCB?

White residue is generally a symptom of ineffective PCB cleaning. Common conductive flux residues from the soldering process can include various unreacted activators, binders, rheology components, and saponifiers. Among these are numerous iterations of acids (abietic, adipic, succinic among others), highly basic ingredients (amino compounds), and even constituents found in “soaps” such as phosphate and sulfate ions. When a cleaner does not fully dissolve all the constituents, or the cleaner is not allowed to flow off the PCB, the remaining solvent can evaporate off and leave behind residue that is either white or like water spots.

How do you clean excess flux?

The most common way to clean flux residues from a repair area is to saturate a cotton or foam swab with isopropyl alcohol or another cleaning solvent, and rub it around the repair area. While this may be adequate for no-clean flux, where the goal is a visually clean PCB, this may not be clean enough when more heavily activated fluxes are involved, like RA or aqueous. The dirty little secret is that flux residues will not evaporate along with the solvent. You may dissolve the flux, and some of the residues will soak into the swab, but most of the residues will settle back onto the board surface. Many times these white residues are more difficult to remove than the original flux. One quick and easy improvement to this process is to rinse the board after swabbing around the repair area. While the solvent is still wet, spray over the entire board with an aerosol flux cleaner. Hold the PCB at an angle to allow the solvent to flow over the board and run off, along with any residues that are picked up. The straw attachment that comes with aerosol flux removers is a good way to increase the spray force and penetrate under the components. Some aerosol flux removers come with a brush attachment. The cleaning solvent sprays through the brush, so agitation can be increased by scrubbing while spraying. To absorb the flux residues, a lint-free poly-cellulose wiper can be placed over the repair area, and the spraying and scrubbing can occur over the material. Then remove the wipe and brush attachment, and spray over the board for the final rinse.
