SMT nozzles are widely used assembly tools in Surface Mount Technology (SMT). Their main role is to accurately pick and place electronic components onto printed circuit boards. Since the nozzles must remain clean and free of obstructions to ensure accurate assembly and high-quality products, regular cleaning of the nozzles is crucial. Preventive Measures and Routine…
PCBA cleaning is a process conducted after the assembly of printed circuit boards (PCBA) to remove contaminants such as solder residue, flux residue, and dust generated during the soldering process. PCBA cleaning equipment typically consists of several main components: When choosing PCBA cleaning equipment, several factors need to be considered: It should be noted that…
SMT nozzles are widely used assembly tools in Surface Mount Technology (SMT). Their primary function is to accurately pick up and place electronic components onto printed circuit boards. Since the nozzles must remain clean and free from obstructions to ensure precise assembly and high-quality products, regular cleaning of the nozzles is essential. Preventive measures and…
Circuit board cleaning machines feature efficient performance and precise control, providing excellent cleaning results. During usage, strictly follow the operating manual and safety procedures of the cleaning machine, and perform regular maintenance and cleaning to ensure its normal operation and outstanding cleaning performance. The Silman Tech intelligent DEZ-C743 circuit board cleaning machine is a high-end…
SMT (Surface Mount Technology) nozzles are essential components in automated pick-and-place equipment, primarily responsible for retrieving surface mount components from feeders and placing them onto PCB boards. The structural principle of the nozzle is as follows: It is worth noting that the structural principle of the nozzle may vary depending on the type of automated…
Pick-and-place machine nozzles are not only critical components for picking and placing components during the operation of pick-and-place machines but also serve as backgrounds for cameras in optical vision systems. They utilize the principle of vacuum suction to pick up components and then place them onto the coordinates of the circuit board using compressed air.…
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?
