As a relatively mature manufacturing method, outsourcing PCB assembly is entering an era of thin profits. The profit margins for PCBA processing are decreasing, while the quality assurance requirements are increasing. A key requirement in PCBA assembly is consistency and accuracy. Differences need to be controlled, and variations are not allowed. Poor quality in assembly…
Solder paste is a paste-like chemical substance that plays two main roles in the soldering process: “removing oxides” and “reducing surface tension of the soldered material.” The functional components of solder paste include the matrix, flux, and surfactant. The matrix is the main component of the solder paste, controlling its melting point. Once melted, it…
Solder paste is a type of soldering material commonly used in the SMT production industry. It is a paste-like solder made by uniformly mixing alloy powder with a flux carrier. Many PCB manufacturers have reported that solder paste easily dries out during the production process. Next, we will introduce the reasons and solutions for solder…
When ordering PCB products, users often produce extras for backup purposes. Over time, these PCB boards may expire without the user’s awareness. So, what are the specific hazards of using expired PCB circuit boards?
In summary, while the thickness and aperture size of the SMT stencil may seem insignificant on the surface, they often determine the quality of our printed electronic circuit boards and should not be overlooked.
In summary, combining oven fixtures with test strategies involves optimizing ICT and AXI testing processes to ensure efficient and comprehensive testing of PCB assemblies.
The application of SMT steel mesh mainly occurs in electronic product manufacturing factories such as those for smartphones, computers, and televisions. These products typically contain one or more circuit boards with numerous electronic components, some of which are very small and cannot be soldered using a soldering iron. Instead, these components are placed on the…
SMT post-solder cleaning equipment mainly includes ultrasonic cleaning machines and water cleaning machines. These are the two common types of SMT post-solder cleaning equipment. You can choose the appropriate cleaning method based on your specific requirements. We hope this information is helpful to you.
Lead tin solder paste is a type of solder paste specially designed and developed for SMT assembly production lines. It is an indispensable soldering material in the SMT pick-and-place machine industry. Lead tin solder paste is composed of flux and alloy components, with tin and lead being the main components, hence the name lead tin…
In the production process of PCBA, various soldering techniques are often used to ensure stability, which can easily lead to residues on the surface layer. To guarantee the performance of the applied products, thorough cleaning is necessary before leaving the factory. What kind of cleaning support can the application of PCBA cleaning machines provide nowadays?…
