SMTOne of the indispensable solder raw materials in the production process is solder paste. The general solder alloy composition of medium-temperature solder paste is:S64.7Bi35Ag0.3,S64Bi35Ag1,S59.9Bi4Cu0.1,S69.5Bi30CU0.5,S82.5Bi17Cu0.5There are five specifications. The solder alloy part accounts for the total weight of lead-free medium-temperature solder paste90%-95%Between the two, solder alloy powder is composed of several alloy materials such as tin, silver, tin and copper, and the impurity residue standard content of the alloy powder is required to be......

In the electronics manufacturing industry, solder paste is a key material used to connect electronic components to circuit boards. Lead-free solder paste and leaded solder paste are two main types of solder paste. However, the question of whether they can be used in combination has long troubled many manufacturers and users. inSMTIt's a waste to throw away the unused solder paste in the surface mount technology. If another type of solder paste is used for the next surface mount, can these two types of solder pastes be mixed together for use? The following is JJY solder paste......

Compared with tin alloys without silver, tin alloys with silver usually perform better during the tinning process, mainly because the addition of silver can improve certain properties of tin alloys. Then why is tin containing silver better for tin plating than that without silver? Here, the tin wire manufacturer will explain: The following are some reasons why silver-containing tin is better tinned than non-silver-containing tin:1Silver can improve the wettability of tin alloy, making it easier to spread evenly on the welding surface, which is beneficial for ensuring the uniformity of the welding and......

We know that currently, there are three types of solder pastes on the market based on different fluxes: rosin solder paste, washable solder paste, and no-clean solder paste. Among lead-free solder pastes, lead-free no-clean solder paste is favored by many technicians in factories. So, what are the characteristics of this lead-free and no-clean solder paste?Now, Shenzhen JJY Solder Paste Manufacturer will analyze for you the benefits of lead-free solder paste that does not require cleaning: water-washable solder paste:Water-washed solder paste uses water-soluble flux. After welding, the residues are prone to react with water......

When many customers receive solder paste, the solder paste manufacturer will remind them that after receiving the solder paste, it needs to be refrigerated and stored. Before use, it should be taken out in advance, and before processing, it should be cooled and stirred evenly. So, why is the solder paste hereSMTIs it necessary to warm up and stir before surface mount technology (SMT) processing? Next, JJY solder Paste Manufacturer will analyze it for everyone:SMTThe solder paste used is mainly stored in the freezer for cold storage. The main purpose is to slow down the reaction speed between the flux and the solder powder. Why does solder paste need to be warmed up......
