How to store low-temperature solder paste? JJY solder paste manufacturer tells you. Is solder paste accompaniedSMTA new type of welding material that emerged as The Times require. Solder paste is a complex system, which is a creamy mixture formed by mixing solder powder, flux and other additives. Because solder paste is a chemical product, it is stored in a cold storage(5~10℃)It can reduce activity and increase the lifespan. Avoid placing it in high-temperature areas as it may cause the solder paste to deteriorate. You can take a look at the general situation......

What is the standard for "lead-free tin wire"? Is lead-free solder wire really lead-free? Lead-free solder wire(99.3cu0.7)It is mainly applied to the welding of handcrafted soldering irons with strict environmental protection standards. Because it is specially made from high-purity raw materials and combined with corresponding flux components, it has good welding fluidity, less smoke and less spatter. It is widely used in the industrial production of environmentally friendly electronic device assembly. Lead-free solder wire, also known as environmentally friendly tin wire, is mainly composed of tin, copper and silver......

Lead-free solder paste is hereSMTIt is widely applied in the processing and manufacturing process, and withRoHSThe popularization of standards has replaced leaded solder paste as the mainstream. However, lead-free solder paste does not represent0%The lead content. Solder paste is an alloy-composed paste. The appropriate composition formula is of decisive significance to the overall soldering quality of the circuit board. Lead-free solder paste does not mean that the presence of lead in the solder paste is absolutely and completely prohibited. It only stipulates that the lead content must be reduced to below1000m(lt0.1%)The level is the same......

JJY Solder Paste Manufacturer answers: What technical points should be noted when printing leaded solder paste? Generally, before applying solder paste, the steel mesh should be adjusted and the printing table and steel mesh should be cleaned thoroughly with alcohol. The height of the steel mesh fixture should be adjusted to ensure that the steel mesh is in close contact with the platform.①Before printing leaded solder paste, it is necessary to inspect the squeegee, steel mesh and other supplies. Ensure cleanliness, free of dust and dirt (keep clean when necessary) to prevent the solder paste from being contaminated by the environment and affecting its tinning properties. The scraper opening should be vertical without any gaps. The steel mesh should be vertical.......

What are the differences between leaded solder paste and lead-free solder paste? Solder paste is mainly a mud-like mixture composed of solder wire powder and flux paste, and is mainly used forSMTIn the field of production and processing, resistors, capacitors,ICThe electronic components are welded by electric weldingPCBOn the board. Solder paste is further divided into leaded solder paste and lead-free solder paste. The key differences between leaded solder paste and lead-free solder paste are as follows4The differences in broad fields. In work, the common solder paste (also known as solder paste) we often see can be divided into two types. Solder paste is made of solder alloy powder......
