What is Solder Paste
Solder pastes are a blazon of aqueous or solvent-based chemical material, fabricated upwardly of tiny solder assurance that, when combined with flux and other chemical products, brand what is called solder paste.
Solder paste usually requires cold storage and brought to room temperature when ready to be used.
Solder paste is widely used in SMD component electronics, SMD only means Surface Mounted parts, but also in traditional electronic component soldering, and is mostly used to improve solder quality.
The solder paste is usually applied using a stencil or direct to the areas to be soldered, and allows, among other things, to eliminate the possible rust existing in the metallic components improving the quality of welding, only information technology too acts as a heat concentrator and this allows its distribution to exist much more homogeneous.
The tiny solder balls mentioned earlier, come in different sizes, T3, T4, T5, etc. the higher the value, the smaller the solder assurance.
As on the market, you can find a great multifariousness of pastes. Therefore, here you volition discover reviews of wonderful options and the buyer'southward guide to larn more than most them.

Best Solder Paste for Stencil and SMD
If you desire a solder paste that can work well with your stencil, I can strongly recommend:
1. ChipQuik TS991AX500T4 – This is a thermally stable (no refrigeration needed). It comes in a jar, which is best because, before each use, you need to stir it well. To practice this, I utilise a flat head screw bit tip and my cordless drill. Makes for a perfect stir stick and easy clean up.
I like the T4 size because it works well for my 0402, WFBGA, and small pitched parts.
Besides, yous may demand to as a bit of flux to re-hydrate the paste after a long fourth dimension of no use, then, I utilize the ChipQuik SMD291 no-clean flux for this. Just squeeze a small amount into the jar and stir.
Brand certain you lot don't add too much. Likewise liquid/runny and you lot will get poor solder flow when information technology comes out of the reflow oven. If the paste is too dry out, y'all will go clumps and your parts may not stick to the board from the pick-n-place.
How to Use Solder Paste
Solder paste is usually applied using a stencil. The stencil is a piece of thin metal with cut outs in in that lets the paste through to sit down exactly on the solder pads of your PCB.
And so a pick-north-place motorcar places your parts on the area where the paste is.
You would put a small amount of solder paste on your stencil, so, putting slight downwards pressure, employ a scraper to slowly pull the paste along the length of your PCB panel. Then gently elevator up the stencil and you are washed.
The Heir-apparent'due south Guide
Solder pastes are specific substances with a paste-similar consistency that are used to prepare parts. They accept sure advantages and disadvantages, likewise as application features. The principal field of application of flux paste for soldering electronics. It can be used for:
- Micro soldering, with or without lead;
- Integrated circuits;
- Soldering of diverse components, SMD or circuits;
- Cleaning debris and residues.
Types of Flux on the Marketplace
Solder pastes are distinguished mainly by 3 characteristics, the blazon of flux, its packaging, and its shape.
Flux Types
- Rosin Flux. It incorporates acid components derived from coniferous rosin, mixed with solvents. Rosin fluxes are used with a tin-lead alloy to solder electronic parts considering they do non leave a corrosive balance. Still, you should keep in mind that they exercise leave a sticky residual that attracts wet and clay and that you should clean with liquids such as trichloroethane.
- Organic Acid Flux. This is a mixture of acids mixed in booze or h2o without rosin, inorganic components, or solvents. Normally, they have a maximum of one-third of the traditional flux. Its apply is limited to cases where the rosin flux is non agile enough. I of their advantages is that they do not usually leave residues and tin exist cleaned with water. The truth is that most fluxes used in electronic devices are of this type.
- Inorganic Acid Flux. This blazon is too a mixture of hydrochloric acid, zinc chloride, and ammonium chloride. It is an active type of flux and is often used to weld metals such as bronze, copper, or even stainless steel with tin can and lead alloys, in domestic plumbing piece of work, or likewise in industrial environments.
- Brazing flux. It is completely different from the previously mentioned ones, and its composition of chemic elements is much more complex. However, its apply is like. You lot mainly use it to remove rust from the parts to be welded.
Varieties of Shapes
Although the most mutual form in which you volition find solder paste is liquid, y'all should know that at that place are up to four dissimilar ways to find this product on the market:
- Aerosol;
- Paste;
- Liquid;
- Dust.
Packaging Type
Perhaps i of the lesser-known aspects is the packaging of solder pastes. Information technology is important to consider information technology and then that its application is as comfy as possible. In the market, yous volition find three types of packaging:
- Syringe;
- Jar, tin, or bottle;
- Marker pen.
Use tips
- Security. Always apply rubber tools when you lot are going to use solder pastes. Remember that it is a element that can harm you lot and therefore you lot must do farthermost precautions during its use in all senses.
- Storage. Each manufacturer has its storage requirements, only remember that these types of products should be stored in places at absurd, but non extreme, temperatures. Make sure to avoid straight sunlight or in areas with high temperatures.
- Earlier using it, you lot must make sure that 24 hours earlier the solder paste must have been at room temperature, otherwise, you will not be able to use it correctly and you will lose all the properties of the solder with a flux that the product gives you.
Whatever welding hobbyist will tell you: buying a new solder paste is similar choosing a new motorcar. At that place are then many options to consider. Honestly, every welding specialist or amateur will tell yous that simply 3 features actually matter when y'all buy these necessary elements:
- Lead-based or atomic number 82-costless structure;
- Alloy ratio;
- Water-washable or no-clean;
I decided to focus on these three parameters as well. I picked thirty different products and tested them in equal conditions, more than or less. The results are reflected in the rating you lot see on this page. The selection wasn't that difficult but there are a few factors a seller may hide or "forget" to mention when you purchase this paste.
Is Soldering Paste the aforementioned as Flux?
No. solder paste contains tiny balls of solder mixed with a flux agent. Flux by itself contains no solder and is merely a paste or gel.
How did I select 3 major products for my rating?
- Temperature Solder Paste is fully compatible with T4 industry standard;
- MG Chemicals has a great "wettability" charge per unit and useful dispenser;
- 247 is another T4 industry standard paste, with 2 dispensing tips;
Other picks in my list are also good, at least, according to my tests. All brands are reputable enough to recommend – ChipQuik, Grade, Silver Like shooting fish in a barrel, Kester, etc.
Really, you should ask yourself earlier buying – what strengths, backdrop, operating temperatures, preferred method of soldering, different metals, and compatibility with welding machines do I need? Yous may inquire your questions here, be happy to assist if I can. Make sure to leave your comments nearly this guide. I can make mistakes and bad choice that is why I try to update each written review regularly. Thanks for reading!
