Occasionally, during the printing process of lead-free solder paste, issues related to solder holes may occurPCBBoard problem. What is the reason for this situation? Today, the solder paste manufacturer will lead everyone to discuss the related issues of solder holes in lead-free solder paste after passing through the furnace. Most of them have the following aspects:1The soldering temperature is very low.2The solder is too dirty, there are many other impurities, the surface layer of the substrate material is contaminated with dust, the printing surface of the screen comes into contact with dust, blocking the screen holes and causing screen hole blockage.......

Can solder paste be thawed repeatedly? This is theoretically possible, but it cannot be achieved in the overall operation process. Why? Today, the solder paste manufacturer will explain. After the solder paste is taken out of the freezer of the refrigerator, it can be repeatedly defrosted under the condition that there is no oxidation in the hypothesis test. But in the overall operation process, have you ever thought that the condition of no oxidation is simply very difficult to achieve? Because you have opened the lid and used it, the solder paste will undergo an oxidation reaction with the oxygen in the air. This......

There are two types of lead-free medium-temperature solder paste: silver solder paste and copper solder paste. And what are the differences between these two kinds of solder pastes? How to choose when in use? Today, the solder paste manufacturer will explain to you: The differences between silver-containing solder paste and copper-containing solder paste mainly come from the following aspects:1The alloy compositions of the two are different. The composition of lead-free solder paste containing silver is tin, bismuth and silver, while the alloy composition of lead-free solder paste containing copper is tin, bismuth and copper.2The melting points of the two are different: as they combine......

DomesticSMTManufacturers have all tasted the benefits of using lead-free solder paste. However, in the face of so many types of solder paste on the market, and each type has a different price. At this time, how should we choose? How much is a bottle of lead-free solder paste appropriate?The following solder paste manufacturer will explain: How much is a bottle of lead-free solder paste? This should be determined by the product cost of the solder paste itself+Technical formula production cost+Any fluctuation in the three aspects composed of labor costs will affect the lead-free solder paste market......
