isopropyl alcohol lcd screen factory

A variety of chemicals can be found throughout the electronic assembly and repair process, but no solvent appears more commonly than isopropyl alcohol. It is universally used for cleaning and as a main constituent of fluxes, but how much do you really know about isopropyl alcohol?

Isopropyl alcohol (CAS #67-63-0) is also referred to as IPA, isopropanol, 2-propanol, and even rubbing alcohol (more on that later). It dissolves a wide range of both polar and nonpolar soils, and is often used to dissolve and remove light oils, fingerprints, cutting fluids, flux residues, carbon deposits, and mold release. It is also readily miscible in water, which makes it an effective drying agent.

For electronic printed circuit board (PCB) assembly, you will find isopropyl alcohol being used either to clean flux residues from recently soldered circuit boards, or in PCB repair and rework. IPA is also used to remove solder paste or adhesive from SMT stencils. Maintenance cleaning with isopropyl alcohol is common for removing caked-on and burnt-on flux from SMT reflow ovens, wave soldering fingers, selective soldering nozzles, pallets, and anywhere else flux tends to collect in automated soldering processes.

Isopropyl alcohol is generally compatible with most materials used in electronics. As with any chemical product used, component compatibility must be determined on a non-critical area prior to use. The following are a list of common materials used in PCB assembly and their respective compatibility ratings:

Isopropyl alcohol is available in a large number of varieties and grades, which are generally differentiated by the amount of water in the solution and trace amounts of other chemicals or nonvolatile materials.

Isopropyl alcohol is hydrophilic, so it readily accepts water into an azeotropic solution. When you see on the label “70% isopropyl alcohol”, it refers to amount of alcohol in relation to the amount of dissolved water – i.e. 70% alcohol to 30% water. Water can be removed to form purer grades of isopropyl alcohol, resulting in what is called “anhydrous” isopropyl alcohol.

Whether an IPA has 0.2% or 50% water has little effect on the look and smell of the material, but greatly impacts surface tension (its ability to wet) and the dry time. The more water isopropyl alcohol contains, the greater the surface tension. This causes the solvent to bead up more as it dries rather than wet or sheet, which can lead to spotting. “Water spots” are particularly problematic when cleaning mirrors, lenses, and other optics.

The dry time is greatly increased as the percentage of water in the alcohol solution is increased. This can be an advantage or disadvantage depending on the application. For example, isopropyl alcohol is often used as a flux remover to remove flux residues from around solder joints. Technicians tend to prefer a fast dry time so that they can clean the electronics and bring them back into service as quickly as possible. When breaking down and removing thick, gummy, or baked-on materials, more dwell or soak time is required. Slowing down the dry time often improves the cleaning effectiveness. That is one of the reasons 70% pure isopropyl alcohol is commonly used for degreasing and SMT stencil cleaning. In the case of electrical contact cleaning, the faster evaporation time helps ensure that the flammable solvent is gone before energizing the equipment.

The general term “rubbing alcohol” is often used for isopropyl alcohol, but users looking to buy a specific grade of alcohol should avoid products labeled that way. Rubbing alcohol does not refer to a specific grade, and may even be a different type of alcohol, like ethanol (also called ethyl alcohol, CAS #67-17-5). Consumer rubbing alcohol can also contain other ingredients like denaturant, fragrances, and colorants that are potential contaminants. ASTM D770 (currently on revision 11(2019)) is the standard specification for isopropyl alcohol published by ASTM International.

As mentioned above, isopropyl alcohol is also available in different grades, or percentages of solvent to water, to fit a variety of specific applications. When deciding on the best isopropyl product for a particular manufacturing or repair process, first decide on the grade of solvent, then the packaging.

Bulk containers- Isopropyl alcohol is packaged in 1 gallon bottles, 5-gallon containers, 54-gallon drums, and even totes for automated dispensing. In most cases, a spigot can be attached to the 1 and 5 gallon containers for convenient dispensing in benchtop or workstation use. When transferring to another container, make sure the smaller bottle is properly marked with the chemical name and warning information.

Small bottles / spray bottles- To avoid the risk and hassle of pouring and labelling smaller containers, isopropyl alcohol is also available in smaller plastic containers like pints and quarts. Some have a trigger spray attachment for convenient cleaning.

Pump dispensers / dauber bottles- Empty bottles are available to make dispensing even more convenient. A wipe or swab can be saturated in the opening, which is filled with a valve when the user pushes down. This keeps the isopropyl alcohol sealed, which avoids cross contamination when a wipe is resaturated after use, causing it to draw in moisture from the ambient air. These bottles can come with a variety of features including ESD-safe materials and a selection of labels for standard chemicals like IPA.

Presaturated wipes- For the ideal mix of form and function, wipes are available, and are already saturated with isopropyl alcohol. They can come in pop-up tubs where the wipes are pulled up from the top, plastic boxes or pouches that reduce linting caused by wipe perforations, and even individually wrapped packages. The individually wrapped wipes are perfect for field maintenance because they fit neatly in a tool box.

Although isopropyl alcohol is generally considered safe if handled properly, it is a flammable solvent, so precautions need to be taken to prevent a dangerous situation from developing.

Storage- because isopropyl alcohol is very flammable, it needs to be stored in a closed container in a cool, well-ventilated area away from ignition sources like heat, sparks and flames. It has an NFPA rating of 3, so it should be stored in a cabinet or room designed for that type of hazardous material. If solvent is transferred to another container, make sure it is marked with the chemical name and required warning information.

Personal protection equipment- isopropyl alcohol has a tendency to defatten the skin, which means it draws out the protective oils from the skin and can lead to dermatitis if improperly handled. Gloves made of nitrile or other solvent-resistant materials should be worn. Glasses or even a face shield should be worn if the user is spraying an IPA product, or if splashing could occur. Respirators can be used if ventilation is not adequate enough to avoid breathing in a high concentration of vapors.

Disposal- isopropyl alcohol needs to be disposed of as a hazardous liquid according to state and local requirements. It certainly cannot be flushed down the drain, and additional disposal requirements may need to be followed depending on the soils dissolved in the waste material.

Safety Data Sheets (SDS)- The central resource for all safety requirements is the SDS, which should be readily available wherever isopropyl alcohol is used.

Is it any wonder isopropyl alcohol can be found in all corners of electronic PCB assembly, rework and repair operations? It is effective, reasonably priced, and safe if handled properly. To buy isopropyl alcohol in the grade and packaging that is best for your application, go to www.techspray.com.

Most are aware of IPA 99% highly effective utilization for medical use and as a laboratory solvent, but Isopropyl Alcohol plays an important role in the everyday maintenance of electronics for businesses, manufacturers, and consumers.

Isopropyl Alcohol 99% is the best substance to use for this purpose. Isopropyl Rubbing Alcohol 91% may also be effective, but it is best to use the purest IPA available.

A cloth, cotton swab, or cotton swab can be applied with Isopropyl Alcohol 99% to the electronic parts that need to be cleaned, but be sure not to leave any fibers on the device components.

Isopropyl Alcohol is commonly found as rubbing alcohol in the grocery store, usually in a 70% isopropyl alcohol 30% distilled water mix; there is no need to dilute it when it comes that way. Some stores may sell 100% isopropyl alcohol which should be diluted. Something about the 70/30 mix causes the alcohol to evaporate away in the most efficient manner, so it"s better to do that than a 50/50 mix.

Isopropyl alcohol should be used only when distilled water won"t do the job, because repeated applications can eventually damage more delicate finishes.

Is your phone screen a bit grimy? Or have you done some soldering on that gaming PC you’re building? Learn how you can safely use isopropyl alcohol to clean your electronics – and when you should opt for another solution.

Cleaning electronics with isopropyl alcohol (IPA) can seem like a simple task – just wipe, swipe, and give it a moment to dry. But electrical gadgets are notoriously delicate. What components can be safely cleaned with IPA? When should you use a milder vs. a stronger solution?

Isopropyl alcoholis made from a chemical process that combines water and propene and then distills it to a given strength, usually from 60-99 percent. (The higher the percentage, the less water is contained in the mixture. The common 70% isopropyl alcohol you buy in a drug store is 30% water.) It has a strong smell, evaporates quickly, and is well-known as a sanitizer, disinfectant, and cleaning agent.

Ethanol or ethyl alcoholis made from fermenting sugars (just like beer or wine). It’s not the same as IPA; you can see our earliercomparison of denatured alcohol vs. isopropyl alcoholfor a more detailed explanation. As a rule, IPA is preferred over ethanol for cleaning electronics because it evaporates cleanly and doesn’t leave behind any potentially harmful residue.

IPA, especially in the higher concentrations, is commonly used to clean electronic components during the manufacturing process. It’s also a go-to solution for many professionals. This is because isopropyl alcohol:

Sanitizes surfaces.IPA kills bacteria and viruses, but it needs some time to do so. This is why lower concentrations (between 60-70 percent) are preferred for sterilization; they have a slower evaporation rate and a longer dwell time (i.e. the time the alcohol is in contact with the surface).

You can use70%,91%, or99% isopropyl alcoholto clean various types of electronics – what you choose will depend on what you’re cleaning. For externals – such as disinfecting your smartphone or TV remote – 60-70 percent will do a better job. The purer higher concentrations are better for removing grime and debris from water-sensitive areas. If, for example, you’re working near a computer motherboard, the lower water amount in 90-99% IPA will prevent even the chance of impurities harming delicate circuitry.

Smartphones, tablets, and computer monitors: Avoid applying anything liquid to the speaker, microphone, camera, and screen area.As mentioned earlier, the best approach is to spray a cleaning cloth and then wipe the device with the cloth. Avoid using IPA directly on the screen, as some manufacturers add an oil-repellent coating to the screen that can be damaged by it. A 50/50 vinegar and water solution is better for touchscreens; just apply it to the cloth as described above.

TVs: If possible, use a damp cloth and a dry microfiber cleaning cloth to remove smudges from your TV. If that doesn’t work, use the vinegar and water mixture in the same way as you would for a touchscreen.

We always advise cleaning electronics with the smallest amount of isopropyl alcohol necessary. It’s usually best to avoid directly spraying the device with alcohol. If you follow the proper precautions, you can safely and effectively clean your electronic equipment with IPA.

Like the OP, I"ve always used a 50/50 mixture of isopropyl alcohol and distilled water. Just now, I seem to have damaged the screen of my (Late 2013) MacBook Pro Retina by cleaning it with this mixture and a microfibre cloth.

There is a coating on the screen that has rubbed off in a patch about a quarter inch wide and two inches long. It"s very noticeable, but luckily it"s on the bezel rather than the screen proper. I"ll probably live with it, as a repair would probably involve replacing the whole screen. ($$$$)

This was possibly the third or fourth time that I"ve used this mixture to clean this screen in the few months that I"ve owned this machine. It"s really annoying to find that the most expensive laptop I"ve ever bought has a screen that can be so easily damaged, using a cleaner that I"ve seen recommended lots of times on the web and which has worked well for me in the past.

If you have been wondering how to clean a monitor with isopropyl alcohol, then let me tell you that the answer is very simple. All you need is a lint-free cloth and a container filled with 99% pure isopropyl alcohol. To start, dip your cloth in the container of alcohol and wipe away grime from your screen without applying too much pressure. After cleaning, let the monitor dry completely before turning it on again.

Use a soft, lint-free cloth. Avoid paper towels or anything else that might contain fibers. If you"re concerned about your monitor"s finish, you should be especially careful when cleaning it with alcohol—so don"t use any kind of rag or cloth you"ve already used on something else. If you"re concerned about dust or other contaminants on the monitor itself, then go ahead and use a small piece of tape to pick up excess dust before cleaning the screen with isopropyl alcohol.

A damp cloth is best for cleaning the monitor"s screen. This will prevent you from scratching it with a dry cloth or paper towel, which could damage your screen and make it harder to see.

Use a lint-free cloth. You don"t want to leave behind any debris, so you want to avoid using paper towels or other cloths that have fibers that could stick to your screen.

Use only enough isopropyl alcohol to clean off the dust and dirt from your monitor. Overapplying the cleaning solution will cause it to evaporate too quickly and leave residue on your screen, as well as potentially damaging it if there"s too much moisture in the air.

Let the alcohol dry completely before turning on the monitor. If you do not, it could damage your monitor and void your warranty. Allow at least five minutes for a regular monitor, and overnight for laptops—the liquid will evaporate faster in warmer weather than in colder.

If you are looking for a way to clean your monitor, then consider using isopropyl alcohol. Isopropyl alcohol is a common solvent used in the medical and pharmaceutical industries, as well as one of the most effective disinfectants around. You can find it at your local drug store or supermarket, usually labeled “rubbing alcohol” or “isopropyl rubbing alcohol”.

Isopropyl alcohol is also very safe to use on monitors because they do not contain any oil or other contaminants that can be removed by detergents such as soap. Another benefit of this cleaner is that it will remove fingerprints without leaving any residue behind (unlike commercial cleaners).

Cleaning your monitor with isopropyl alcohol is a simple way to keep it looking good. It’s also cheap and easy to do, so there’s no reason not to try it. The alcohol will remove dust and fingerprints from both LCD and CRT monitors, leaving them looking like new again!

For this reason, we have put together some guidelines for cleaning and disinfecting TRU-Vu touch screen monitors.  This can be achieved without causing any damage to the touch screen

The U.S. Centers for Disease Control and Prevention (CDC) states: “diluted housed bleach solutions, alcohol solutions with at least 70% alcohol, and most common EPA-registered household disinfectants should be effective” for disinfecting surfaces to prevent the spread of coronavirus (COVID-19).

Avoid using abrasive cloths, such as rags or paper towels, as they can spread lint and/or even damage the screen. Instead, use only non-abrasive cloths, such as soft lint-free cloth, in order to avoid scratching the monitor.

Dampen a new clean, non-abrasive cloth with a disinfectant recommended by the CDC: a household bleach solution (1/3 cup of bleach per gallon of water) or Isopropyl alcohol ( 71% to 85% alcohol). Be sure to squeeze any excess liquid off of the cloth. Do not spray the solution directly onto the touch screen.

Apply the solution to a soft cleaning cloth; do not spray directly onto the touch screen. Wear gloves during the cleaning process. Finally, discard both the gloves and the cleaning cloth following the cleaning process.

You may need to use a dampened microfiber cloth to get rid of stubborn smudges and stuck-on debris, though. If you"re worried about germs, consider using a vinegar and water solution or a Lysol wipe on the screen. Be sure to check the device’s user manual first to make sure it’s okay to use liquids!

When a laboratory has an abundance of electronics that need to be kept in working order, eventually it’ll be necessary to find the right chemical to use for cleaning. For most laboratories, a solution comprised of distilled water and an alcohol is the right solution because of its low-cost and high-efficacy cleaning potential. But, especially for laboratories which may just be getting established for the first time, it may be unclear which alcohol is the appropriate choice to make the cleaning solution.

The question of ethyl alcohol vs. (IPA)for cleaning electronics has several ramifications for the laboratory supply chain as well as the longevity of laboratory hardware. To shed light on this issue, it’s necessary to briefly discuss why electronics need a special cleaning solution at all.

Ethyl alcohol is a great choice for cleaning electronics in the laboratory because it’s inexpensive, mineral-free, and evaporates quickly.While ethanol isn’t a strong solvent, it is typically sufficiently powerful to clean sensitive electronics which may have accumulated light layers of corrosion or dirt. It’s also a useful chemical for a plethora of laboratory tasks ranging from basic sterilization to removing labels from old pieces of hardware.

is the more common choice for cleaning electronics because it evaporates more rapidly than ethanol and also because it does not leave any traces of oils upon evaporation. Similarly to ethanol, most laboratories have ample quantities of isopropyl alcohol (IPA) around for general purpose use.

However, unlike ethanol, the most common sources of laboratory isopropyl alcohol are ready to use for cleaning electronics. Lab wipes and reagent-grade bottles of isopropyl alcohol are each pure enough to clean sensitive electronic components without hazard.

Not all electronic components are compatible with isopropyl alcohol cleaning, however. In particular, polycarbonate electronic components, typically in PCBs, seals and gaskets, are extremely harmed by exposure to an isopropyl alcohol cleaning solution. While it may be possible to mitigate the impact of the cracking which occurs when isopropyl alcohol seeps into the polycarbonate by using a more dilute cleaning solution, a better strategy is to avoid using isopropyl alcohol on these components entirely.

Notably, isopropyl alcohol also combusts more readily than ethanol. While the difference is negligible in most lab situations as both will alight when exposed to an open flame, laboratories which routinely operate sensitive experiments at high heat may find that isopropanol is too volatile to be safely used for cleaning components which may still be warm from use. Importantly the residual oils from ethanol may be problematic in this context as well, so the advantage of ethanol is not assured.

Anticipating a laboratory’s utilization of key cleaning chemicals like isopropyl alcohol is significantly easier when a laboratory works with a knowledgeable supplier who understands the lab’s typical needs. By working with the right supplier, labs can ensure that they have consistent access to the chemicals they need, when they need them.
