Flux is one of the most critical auxiliary materials in the electronics industry, directly affecting the quality and stability of electronic product assembly processes. With the rapid development of the modern information electronics industry, the demand for flux has increased significantly, raising the standards for flux selection. Flux mainly consists of activators, solvents, surfactants, and…
Traditional manual cleaning of ink screens after printing usually involves using shredded cloth dipped in cleaning solution or anti-white water for wiping. Cleaning one side before proceeding to the other side is a common practice in this process. However, there are several challenges associated with this method: To address these issues:
The soldering process in PCBA assembly is fundamental in determining electrical performance and reliability. Studies have shown an increasing trend in problems such as corrosion, short circuits, and open circuits caused by corrosion and electrical migration. Previously, our understanding of cleaning was inadequate, as we believed that the residual flux was non-conductive and benign, and…
PCBA stands for Printed Circuit Board Assembly. It refers to the process of assembling various electronic components onto a PCB (Printed Circuit Board) using surface mount technology (SMT). Once the PCB is assembled with components, it is then assembled with other parts such as the casing to form the final product. In other words, PCBA…
The surface of the PCB board includes the copper foil substrate and the pre-plated copper substrate after hole metallization. To ensure the firm adhesion of the dry film to the substrate surface, it is required that the substrate surface be free of oxidation, oil contamination, fingerprints, and other contaminants, as well as free of burrs…
