The evolution of PCB surface treatment technology, influenced by environmental concerns and evolving industry standards, emphasizes lead-free and halogen-free processes like organic coating and electroless nickel plating/immersion gold, while also considering factors like component type and assembly requirements, leading to a dynamic landscape of options with a focus on meeting customer needs and environmental standards.
The emergence of Ball Grid Array (BGA) packaging, with solder balls replacing pins, revolutionizes electronic assembly, offering versatility and overcoming limitations of traditional packages like Quad Flat Packages (QFP), leading to derivative packages like Chip Scale Packaging (CSP). BGA assembly involves considerations such as pad design, solder paste printing, alignment accuracy, temperature profile, and defect prevention. Prioritizing CAD tracking feasibility and PCB manufacturability, BGA pad design aims to minimize soldering defects and accommodate future rework, with types like dog-bone pads requiring careful sizing to avoid manufacturing issues like solder bridging.
