Optimizing Airflow Organization to Enhance Cleanliness in PCB Clean Rooms

Optimizing Airflow Organization to Enhance Cleanliness in PCB Clean Rooms

Enhancing cleanliness in PCB clean rooms through optimized airflow organization can be approached from the following key aspects: 1. Reasonable Planning of Airflow Direction and Area Division Unidirectional or Mixed Flow Mode: Implementing vertical unidirectional flow or horizontal unidirectional flow modes allows clean air to flow from clean areas to contaminated areas, carrying pollutants out … Read more

Unit 3: Voids in Coating Layers Inside PCB Holes

Unit 3: Voids in Coating Layers Inside PCB Holes

During visual inspection (non-sectioning), voids in the copper layer and coating layer of the hole (void) are common defects. Voids identified during visual inspection refer to areas exposing the substrate material, while voids identified through section analysis refer to areas below the minimum thickness specification, indicating a fundamental difference between the two. Different grades of … Read more
