What is gold solder paste?
Paste solder offers particular advantages when used when soldering rope chain, hollow shells, findings, earring posts, and jump rings. The Paste for Gold Filled contains a highly active combination of chemical fluxes added to the paste to clean and protect the base metal and solder during the heating cycle.
Do you need flux with solder paste jewelry?
There is no need to separately apply flux or borax, Just apply the paste and heat. Start slowly with a soft flame warming the piece first. The paste will dry out, and then melt to clean and flux the joint. With more heat, the microscopic particles of solder will melt together forming the solder and filling the joint.
How does solder paste work?
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.

How to solder gold?
To solder gold, first you'll need to get some gold solder and a precision torch. Once you have your supplies, prepare a water bath and a pickle bath, which is a solution used to clean oxidization off metals. Then, holding the gold in place on a soldering block with copper tongs, apply a small amount of flux to the gold and heat it with the torch. Flux is just a chemical that aids in the soldering process. Next, apply some gold solder and then heat the surrounding gold objects to join them together. Finally, treat the joined piece with the water and pickle bath. To learn how to prepare a water bath and a pickle bath, scroll down!
How to clean gold solder?
Clean gold thoroughly. The gold surfaces to be joined need to be clean of dirt and grease for the solder to chemically bond them together. Soak them in the pickle solution briefly to remove surface contamination, then rinse in water to remove the acid. Scrub the surfaces with detergent or soap for additional cleaning.
What is flux solder?
Flux is just a chemical that aids in the soldering process. Next, apply some gold solder and then heat the surrounding gold objects to join them together. Finally, treat the joined piece with the water and pickle bath. To learn how to prepare a water bath and a pickle bath, scroll down!
How to get rid of fire scale on metal?
After a couple minutes, quench it further in the water bath. Use copper tools to lower the gold slowly into the pickle bath, and wait a few minutes for most of the discoloring fire-scale on the surface to be removed.
How to join two pieces of gold together?
Apply a small amount of solder and heat. Place a chip of solder on one end of the seam to be joined, and heat the surrounding gold objects. If you are using an appropriately high-temperature torch, you should be able to heat that area sufficiently to melt the solder without having to heat the entire object. Move your flame back and forth slowly as you heat, to apply the heat across the length of the seam to be joined. The solder should melt and flow across the seam, visibly joining the two sides together.
What solder to use for a 14 karat gold?
Solder with a higher gold content is stronger, but takes more heat to melt. It is recommended for joining two pieces together. Use "plumb solder," "medi um" or " hard" solder, or solder with 14 karat and above.
How to join gold in a soldering block?
Hold the gold in place. Place the gold objects on a soldering block, and hold in place with tweezers or a clamp. The areas to be joined together should fit together as closely as possible; this process cannot typically fill large gaps.
What is gold tin solder paste used for?
Gold-tin solder paste is used in a variety of high-reliability applications, where its high melting point, non-creep, high-tensile stress, thermal and electrical conductivity, as well as proven usage life makes it a standard "known-good" material.
What temperature is gold tin solder paste?
Gold-tin solder paste is generally used in applications that require a high melting temperature (over 150°C), good thermal fatigue properties, and high-temperature strength.
What is the melting point of 182?
Indalloy® 182 (80Au/20Sn) has a melting point of 280°C (556°F). It can be made into solder paste form with various options to address specific applications. Gold-tin solder paste is generally used in applications that require a high melting temperature (over 150°C), good thermal fatigue properties, and high-temperature strength. It is also used in applications that require a high tensile strength and high corrosive resistance, or in step soldering applications where the paste will not melt during a subsequent low-temperature reflow process. For these reasons, Indalloy® 182 solder paste is widely used in military, aerospace, high-power LED, and medical applications
How to store solder paste?
Store it in an airtight container so that oxidation cannot occur. Solder paste (all forms of solder for that matter) do not work well in hot temperatures. Make sure that you are storing it at low temperatures. This keeps the flux lasting longer at a higher quality. It also helps prevent oxidation.
What is solder paste used for?
If you are working on PCB assembly projects , solder paste is essential to complete the task. The paste itself is a mixture of minute solder spheres that are held within a specialized form of paste flux. Aside from PCB assembly, this paste can also be used in stencil printing which is completed by a stencil printing machine and reflow process which is done by the reflow oven.
What is the minimum size of solder paste?
The minimum size is two millimeters and the maximum size is 150 millimeters, though there is a 20% chance that some might fall outside this category either being smaller or larger. The grading system is how solder paste is generally categorized, but there are also sections based on the type of flux used.
What is solder mixture?
The particles themselves are a mixture of different types of solder. After the legislation passed banning lead use, the mixtures are mostly tin and copper. Some use a substitute for copper, but tin is always an essential ingredient.
Does solder paste expire?
It also helps prevent oxidation. Just don’t let the temperature get below freezing. It's imperative that you do not use your solder paste past the expiration date since the product does degrade even when kept in the best storage conditions.
What is solder paste?
Solder paste can be used to solder in tricky situations, it is available from the studio shop.
How to use a syringe plunger?
How to use it: Remove the lid from the end of the syringe – if you want to use a needle then twist this needle on to the end of the nozzle where the lid was. Press the plunger in to the cylinder until a small amount is pushed out of the end. Don’t forget to replace the lid – it can dry out!
Can you use solder paste on silversmithing?
But beware of turning your back on our old friend. Traditional solder can sometimes be tricky to use but is often the best way to make a good join. Each has their appropriate use. If you struggle with traditional solder then persevere and use it more, you will get better and your jewellery will be better. If your work involves small findings and wire details then give solder paste a try.
Can solder paste be brittle?
Finally –it still has to flow like normal solder. A join can be brittle if the solder paste hasn’t reached temperature – it may still join unlike traditional solder in this situation, but it will be weak. Recognising when this has happened will come with experience.
Is silver solder paste hard?
Silver solder paste is also available in easy, medium and hard. It is a fairly expensive material to buy especially in gold. As a rough idea 3 grams of 9ct gold easy solder paste is just a bit more than double the price of 30 grams of silver solder paste.

Traditional solder can sometimes be tricky to use but is often the best way to make a good join. Each has their appropriate use. If you struggle with traditional solder then persevere and use it more, you will get better and your jewellery will be better.
Can you solder jump rings with side cutters?
If you cut jump rings with side cutters instead of sawing them – then traditional solder will fill the little ‘v’ gap made by the cutter to a certain extent. Solder paste won’t! Solder Paste will join sawn jump rings neatly but I have never got on with it for this either.
