Solder paste accompaniesSMTA new type of welding material that has emerged as The Times require is a paste-like mixture formed by mixing solder powder, flux paste, and other surfactants, thixotropic agents, etc. At room temperature, the paste can initially bond electronic components in the predetermined positions. When heated to a certain temperature, as the solvent and some additives evaporate and the alloy powder melts, the components to be soldered and the solder pads are connected together. After cooling, a permanent connection point is formed. The requirement for solder paste is complete......

Solder paste.PCBASolder paste is an important raw material in the production and processing of surface mount technology (SMT), playing an indispensable role in SMT soldering. Generally, solder paste is a paste-like solder made by uniformly mixing alloy powder, paste-like flux paste and other carriers. SometimesPCBAThe factory found that the solder paste dried out easily during the production and processing. So, what's going on here? Below, Shenzhen JJY Solder Paste Manufacturer will briefly introduce some reasons for solder paste drying out: First, during the reflow soldering process, solder paste is prone to drying out.......

SMTIn solder paste processing factories, there are a wide variety of solder paste types and specifications, even for the same oneSMTThe solder paste used by surface mount technology (SMT) processing plants in SMT processing also varies in terms of alloy composition, particle size, viscosity, cleaning methods, etc., and the price differences are also significant. Then how should one choose the appropriate oneSMTWhere is the surface mount solder paste? Generally, the selection should be made in combination with the specific production environment, referring to the activity, viscosity, powder shape, particle size and melting point of the solder paste for surface mount processing.1,......

SMTSolder paste processing is one of the most common surface mount technologies in the electronics industry at present. ThroughSMTTechnology enables the installation of more, smaller and lighter components, enabling circuit boards to meet the requirements of high precision and miniaturization. Sure, this is rightSMTThe technical requirements for surface mount technology (SMT) processing are higher and more complex, so there are many matters that need attention during the operation process. The following is the summary and introduction of Shenzhen JJY Solder Paste Manufacturer:SMTThe precautions for using solder paste in surface mount technology (SMT) processing are as follows:1Storage temperature: It is recommended to store on ice......

inSMTOccasionally, during solder paste processing, there may be"Erect a monument"(That is, the Manhattan phenomenon)The phenomenon occurs, and this situation often happens inCHIPComponent(Such as surface mount capacitors and surface mount resistors)During the reflow soldering process, the root cause is that when the solder paste on the pads at both ends of the component melts during reflow, the wetting force on both sides of the component is unbalanced, which leads to the occurrence of the stele phenomenon. Now, Shenzhen JJY Solder Paste Manufacturer will explain it to you:SMTThe specific reasons for the occurrence of the stele erection phenomenon in solder paste processing:......
