“Cleaning” is often overlooked in the PCBA manufacturing process, with many considering it to be an unimportant step. However, ineffective cleaning during the initial stages of product application can lead to numerous problems in the long term, resulting in increased costs due to rework or product recalls. In the following, we will briefly explain the…
PCBA components boards, having undergone processes such as SMT reflow soldering, DIP wave soldering, or selective wave soldering, invariably contain residues of flux and solder paste. Despite the term “no-clean” associated with modern electronic chemicals such as solder paste and flux, it does not indicate the quantity of residues left on the PCBA components board…
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…
Firstly, consider the strength of the team. A reputable manufacturer of BGA rework stations must have a skilled manufacturing technology team, which is crucial for ensuring product quality. Additionally, they should have a professional and reliable after-sales team capable of providing high-quality service to customers nationwide. Secondly, consider the long-term development of the company. A…
Selective wave soldering machine equipment has been invented for over 50 years now and has been crucial in the automated mass production of electronic devices, particularly for soldering through-hole components on circuit boards, offering high production efficiency and automation levels. With the emergence of various surface-mounted component packaging forms in recent years due to the…
