HASL technology, while established, faces challenges in achieving consistent quality due to its operation in high-temperature, high-pressure environments. This paper discusses strategies to improve process control in HASL, focusing on flux selection, process parameter control, and achieving uniform solder coatings essential for PCB manufacturing.
HDI PCBs are critical in diverse applications due to their complexity and capabilities, yet their manufacturing presents challenges such as design intricacies, stringent precision requirements, and complex processes. These difficulties, including defect risks and limited through-hole options, underscore the importance of rigorous quality control for reliable production.
OSP serves as an insulating layer between copper and air, making it cost-effective but challenging due to transparency and non-conductivity. Gold plating enhances soldering and prevents corrosion, albeit at higher costs. ENEPIG, with a palladium layer, offers corrosion resistance and versatility. Immersion silver provides simplicity and speed, while immersion tin, though compatible with all solder types, historically faced reliability issues but has been improved with organic additives. Each surface treatment has unique characteristics, but ENEPIG stands out as versatile.

Recycling and processing methods of waste PCB include physical, chemical, and biological methods. Physical methods involve stripping the PCB and using techniques like mechanical crushing and sorting based on physical properties. Chemical methods include pyrometallurgy and hydrometallurgy. Alkaline paint stripping is an effective way to separate the paint from the circuit board structure for metal recovery. Overall, physical methods of PCB recycling are simple, scalable, cost-effective, and environmentally friendly, but face challenges such as incomplete metal separation and high initial costs.
