Which is more prone to oxidation, leaded solder paste or lead-free solder paste?Dec 29,2022

During storage or use, leaded solder paste and lead-free solder paste are prone to oxidation by air. So, which of the two is more prone to oxidation? Today, the solder paste manufacturer's editor will tell you all about it. The most common difference between leaded solder paste and lead-free solder paste lies in whether it contains lead, and the lead element is precisely the key factor that distinguishes the oxidation rate of the two. When lead is added to tin, it will have excellent mutual solubility, oxidation resistance, corrosion resistance and other properties. When the temperature is as high as210~230Degree of time......

What causes the viscosity of lead-free solder paste to be insufficient?Dec 28,2022

PCBWhen using lead-free solder paste for plate soldering, the problem of poor viscosity of the solder paste may occasionally be encountered. What causes the viscosity of lead-free solder paste to be not good enough? The solder paste manufacturer would like to have a brief discussion with everyone: The viscosity of lead-free solder paste is not good enough, and most of them usually have it3One situation:1If lead-free solder paste is too dry, its viscosity will also decrease. Just like staple food rice, when rice is moist, it has viscosity, but whenever it dries, its viscosity disappears......

How to choose lead-free solder paste reasonably? A brief discussion.Dec 27,2022

How to choose lead-free solder paste? How can lead-free solder paste achieve the best soldering effect without causing waste? Today, the solder paste manufacturer will explain to you how to use lead-free solder paste reasonably: As long as it is not used directly, lead-free solder paste should first be stored at low temperatures, and usually stored in0-10℃Inside the refrigerator or freezer. The shelf life of lead-free solder paste begins when it is produced6It is about one month. If it exceeds the period, it will be stopped from use. Choose lead-free solder paste......

What should be noted after taking lead-free solder paste out of the refrigerator?Dec 26,2022

Before printing, lead-free solder paste must be well prepared; otherwise, it will affect the printing and soldering effect. So, what are the matters that need attention?The following is what the solder paste manufacturer will tell you:1After taking the solder paste out of the refrigerator, pay attention to the expiration date of the solder paste. If it has expired, it is not recommended to use it and it needs to be scrapped. When taking solder paste, the principle of "first in, first out" should be adhered to. If there is any previously opened and unused solder paste, it should be chosen first.2Lead-free solder paste from......
