“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…

Special Opening Design Principles:

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…

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…
