How Does Flux Affect Soldering Quality?

Flux plays a crucial role in the soldering process; its performance and quality directly affect the reliability, appearance, and mechanical properties of the soldered joint. The following outlines the main impacts of flux on soldering quality and a detailed analysis:

Why Is Flux Added to Solder Paste?

Flux is added to solder paste to remove metal-surface oxides, prevent re-oxidation, reduce the surface tension of the solder, and improve wettability

How to Choose a Solder Paste Squeegee?

Selecting a solder paste squeegee requires comprehensive consideration of material, shape, size, hardness, and process requirements to ensure print quality, efficiency, and equipment life. The following are specific selection points, recommendations, and example recommended configurations:

How to Choose a Suitable Solder Paste? & a Solder Paste Manufacturer?

The chip semiconductor industry has developed vigorously in recent years, and the supporting industries related to microelectronics and semiconductor packaging have achieved unprecedented development. Various companies have sprung up, including the packaging solder industry of solder paste as well.

How Should Solder Paste Viscosity Be Controlled When Measurements Are Inaccurate?

naccurate solder paste viscosity measurements can directly affect print quality, soldering performance, and product reliability. Control must therefore cover equipment, operating practices, the environment, and materials. The following measures are recommended:

How Can Pad Misalignment and "Solder Paste Bleeding" in Solder Paste Printing Be Resolved?

Pad misalignment and "solder paste bleeding" during solder paste printing should be addressed systematically across four dimensions: equipment calibration, process parameter optimization, material-property matching, and design improvement. Specific measures are provided below:

Halogenated vs. Halogen-Free Solder Paste

Halogenated and halogen-free solder pastes differ significantly in composition, soldering performance, environmental impact, cost, and application. The details are as follows:

How to Reduce the Formation of Solder Balls

There are solder balls with sizes about 0.2mm~0.4mm, or some exceed this range, which is mostly concentrated around chip RC components. The existence of solder balls not only affects the appearance of electronic products but also brings hidden dangers to product quality.
