ENIG vs HASL – which PCB surface finish is right for your application?
Not all PCB pads are created equal. 👀
The surface finish you choose can affect solderability, pad flatness, component compatibility, reliability, and cost – so it’s more than just a finishing touch.
🟢 ENIG – highly planar and well-suited for fine-pitch components, high-density designs, and demanding applications.
🔵 HASL – proven, reliable, and cost-effective for many conventional PCB designs and assembly requirements.
So, which one should you choose?
There’s no one-size-fits-all answer. The best finish depends on your PCB design, components, assembly process, and performance requirements.
