Alternatives To Isopropyl Alcohol In Electronics Repair And Assembly

Isopropyl

what is isopropyl alcohol?

Isopropyl alcohol  (CAS # 67-63-0), also known as ipa Alcohol , isopropanol or  2-propanol, is a common solvent in the electronics assembly and repair industry. Companies use isopropyl for flux removal, circuit board cleaning, stencil, and industrial degreasing.
Quang TrungChem currently offers isopropyl alcohol which is equally effective as solder fluxes, circuit board cleaners, circuit board cleaners, etc. If not better than that.
Solutions using isopropyl alcohol to replace solvents are suitable in all cases, industries and fields, bringing efficiency with lower costs.

QuangTrungChem offers isopropyl alcohol alternatives for:

  1. Electronic printed circuit board (PCB) assembly
  2. Remove arc or adhesive from SMT Stencil
  3. Cleaning and maintenance of electrical equipment
  4. Removes water flux, circuit residuals
  5. Industrial Degreaser

However, in some cases this alcohol cannot be purchased. You can completely use some of the following chemicals, substances, and solvents instead. The replacement decision is provisional and for reference only. If something goes wrong, please leave a comment below to let us know. Thank you.!

3 alternatives to isopropyl alcohol in electronics repair and assembly

  1. Isopropyl alcohol with flux – FLUX

Flux flux is mainly used to prepare contact and conductive surfaces before welding. It promotes proper wetting of the solder, so it flows over the metal surface and creates a metallic bond.

Alcohol-based Flux flux is mainly produced from isopropyl alcohol, so there is not much difference when used as a  substitute for isopropyl alcohol.

Of course, when comparing these two types, a solvent that is specifically manufactured and has other ingredients added to the solder flux is better than isopropyl alcohol.

But the reason we decided to recommend isopropyl alcohol over FLUX flux is because it costs less and still gives the same effect.

Some solutions that use isopropyl alcohol to remove flux replacing FLUX flux  include the following lines:

  • E-LINE Flux Remover,
  • PWR-4 Flux Remover,
  • G3 Flux Remover và Precision-V Cleaner.

In the best condition. You should use the above solvents. All of them have a higher cleaning performance than isopropyl alcohol and each has additional advantages.

  1. Flux cleaner and isopropyl alcohol

An eco-friendly, water-based cleaner designed to work in inline, batch and ultrasonic cleaning equipment. IS the optimal combination of solvent and saponifier that reduces surface tension for penetration in low temperature conditions, and powerful cleaning action to remove all flux deposits.

2.1.  Eco-stencil detergent with isopropyl alcohol

The unique DI water and solvent mixture is effective in removing a wide variety of pastes and adhesives. Isopropyl alcohol with a concentration higher than 91% can be used for more difficult pastes and adhesives.

Eco-Stencil RF contains no ions and will not leave behind contaminants that alter downstream process windows or lead to board failures. Isopropyl alcohol can also be used as an alternative to clean residue and water without causing circuit failure, short circuit.

Both isopropyl alcohol and Eco-Stencil UM cleaning solution effectively clean  all types of solder paste ( e.g. water-based, RMA, bleach-free, lead-free) and unlikely adhesives. shield from screens, misprints, and equipment.

2.2. Advantages of Eco stencil cleaning solution compared to isopropyl alcohol

However, Eco-Stencil RF cleaning solution is an effective non-flammable alternative to isopropyl alcohol and other solvents commonly used in no-rinse group stencil cleaning systems.
Eco-Stencil UM is completely safe on stencils, rubber brushes. Compared with isopropyl alcohol , it is an ideal substitute because it does not damage the starting material, alcohol or gasoline changes the properties of materials made from rubber, hard plastics, etc.

  1. Isopropyl alcohol and cleaning solutions for wave soldering machines

Isopropyl alcohol is a cleaning agent used for routine preventive maintenance to keep electronic assemblies operating at peak performance.

Advantages

  • Isopropyl alcohol removes heated flux residues from reheat furnaces, wave soldering systems, associated heat exchangers and selective solder nozzles.
  • Isopropyl alcohol is effective in removing all types of flux deposits.
  • Isopropyl alcohol is common and easy to find at a relatively cheap price

Comparison of degreasing solution and isopropyl alcohol with acetone

Both isopropyl and acetone are effective degreasing solutions and are the main ingredients in detergents and grease removal solutions. However, there are some cases where both chemicals can work best in one respect. Consists of:

Isopropyl alcohol is commonly used for light degreasing, especially in food processing facilities.
Acetone  is a popular choice for flux removal, stencil cleaning, electronic assembly equipment maintenance, and light degreasing .

Isopropyl alcohol is used to clean inks on plastic surfaces without affecting quality and effectiveness.

Acetone is often used to clean adhesives, plastic glues, paints more effectively than isopropyl.

In household cleaners, isopropyl alcohol is recommended as an alternative to acetone which is volatile, highly toxic, and is a U.S. level 3 neurotoxin.

Where to buy both isopropyl alcohol and acetone chemicals

Quang Trung Trading Production  Co., Ltd. based in Tan Binh district, Ho Chi Minh City, Vietnam . We mainly supply  pharmaceutical intermediates, chemical raw materials, chemical disinfectants, flavors and fragrances, food additives, etc.

Quang TrungChem has the ability to  import and export independently. We mainly export various chemical products as well as solvent intermediates. The consumption market is widespread, mainly the European market and the domestic market.

Quang TrungChem insists on using quality  to enhance  the company’s core competitiveness.  The desire to establish a good social image accompanies  the development. Respect the corporate spirit of ” go ahead, innovate. Learn, promote and create “.
