Is solder paste a hazardous material?
yes Health Hazards (acute and chronic): Contact with material or fumes may cause skin, eye and respiratory tract irritation or burns. Severe inhalation can cause pulmonary edema, which may not manifest for several hours after exposure. Ingestion may result in irritation or burning of the digestive tract.
What does solder paste contain?
Solder paste is a combination of a powder made up of metal solder particles and sticky flux that has the consistency of putty. The flux not only does its usual job of cleaning the soldering surfaces of impurities and oxidation, but it also provides a temporary adhesive that holds the surface mount components in place.
What is the composition of solder paste used for soldering process?
Lead-Free Solder Paste Lead Free Solder Wire and Solder Paste are manufactured using different composition and ratio. But the most popular and widely used composition and ratio is SAC (Tin Silver Copper) in the Ratio 96.5% Tin + 3.0% Silver and 0.5% Copper.
What is the name of the paste used to clean metal surfaces for soldering?
Flux is a chemical cleaning agent used before and during the soldering process of electronic components onto circuit boards. Flux is used in both manual hand soldering as well as the different automated processes used by PCB contract manufacturers.
Is soldering paste the same as flux?
Solder paste flux is different than liquid flux in both physical form and activity level. Solder paste flux typically contains 60-80% by weight active ingredients, compared with liquid flux’s 2-25%. By weight, a mixed solder paste commonly consists of 90% metal.
Does solder paste need to be refrigerated?
Solder paste should be transferred immediately to controlled storage on receipt. Refrigeration is recommended but may not be required. AIM solder pastes typically have a shelf life of three to six months when stored at room temperature (22°C/72°F).
What’s the difference between soldering paste and flux?
While the main use of solder paste flux is in the creation of solder paste, it is also sold directly as a gel or tacky flux. Solder paste flux can also act as a temporary adhesive. Once mixed, solder paste is most commonly used in a stencil-printing process.
How many types of solder paste are there?
Most solder paste users prefer Type 4 solder paste for 0201 imperial, 01005 imperial, micro-BGAs and similar components. Type 5 solder paste is typically used for even smaller soldering applications, or when Type 4 solder paste does not print adequately.
Is solder paste and flux the same?

What is Type 3 solder paste?
The main particle size range is normally associated with the type. For example, Type 3 solder powder mainly falls within the 25 – 45 µm size range, therefore Type 3 solder paste may be labeled as “Type 3 (25-45 µm).” Below are images of these three sizes of solder powder.
