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? 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......

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......

We all know that solder paste is divided into halogen-free and halogenated types, and halogen-free is an inevitable trend that solder paste is bound to develop in the future. So, what exactly is the advantage of halogen-free solder paste? What are its advantages? Below, the solder paste manufacturer will explain the advantages and disadvantages to you: The advantages of halogen-free solder paste are as follows:1.No halogen compound residues.2.Excellent printability eliminates omissions during the printing process.3.It has good solderability and appropriate wettability on all types of components.......

Anyone who has used solder paste knows that it should be stored at a low temperature before use. So why is low-temperature storage necessary? Is it true that the lower the storage temperature, the better? Today, the solder paste manufacturer will explain to everyone: I believe everyone knows that there are active substances inside solder paste, and these active substances can all play a role in removing oxides. The ability of active substances to release active agents is related to temperature to a certain extent. The lower the temperature, the weaker the release of activity. So, in order......
