Is the export of solder paste regulated?

Solder paste exports are not all controlled, but companies need to assess the risk based on product composition, use and target market dynamics.It is recommended to establish a compliance system, including composition testing, licence application, declaration specifications, etc., in order to avoid legal risks.

In-depth analysis of solder paste viscosity standards

Solder paste viscosity standards need to be combined with specific application scenarios, test methods and industry standards to make a comprehensive judgement.By accurately controlling the viscosity and thixotropic properties, SMT process yields can be significantly improved, and printing defects and soldering problems can be avoided.

What solder paste do I need to solder a mobile phone motherboard?

Soldering mobile phone motherboards requires the selection of solder paste suitable for high-density, fine solder joints, and the following are key factors and recommendations:

Device failure due to SMT wick effect

The wick effect, also known as the creeping tin effect, is an inherent characteristic of solder in the PCB soldering mechanism: "solder always flows from low temperature to high temperature", which means that the nature of solder is to go where the temperature is high.

What are the brands of solder paste widely used in China at present?

The widely used solder paste brands in China include both internationally renowned brands and excellent local manufacturers.

The physical characteristics and application areas of tin powder

As an important metal powder material, tin powder, by virtue of its unique physicochemical properties, shows a wide range of application value in a number of industrial fields.The following is a detailed description from both physical characteristics and application areas:

Wave Soldering Solder Pull Tip is How to Form

Wave soldering, sometimes found at the top of the components and pins or solder joints with icicle or stalactite-like solder, this phenomenon is called pull tip, as shown in Figure.

What is the difference between solid crystal solder paste and red glue?

Solid crystal solder paste and red glue are two common materials in the field of electronic packaging, and they have significant differences in composition, function, process, performance and application.
