Single-sided HASL PCBs utilize a single-layer wiring design and a HASL (Hydraulic Aluminum Sintering) process, offering strong oxidation resistance and excellent soldering performance, making them suitable for cost-effective electronic devices. The HASL layer protects the copper foil, extending its service life. Its single-sided construction allows for short production cycles, making it suitable for volume orders. It supports both manual soldering and SMT processes, accommodating a wide range of components. Suitable for low- to medium-complexity circuits in applications such as home appliance control boards, LED lighting, power modules, and toy electronics.
