But Emma was insistent. She knew that cutting corners on the soldering process would compromise the integrity of the device, and she was determined to get it right.

is the industry standard specification for Electroless Nickel / Electroless Palladium / Immersion Gold (ENEPIG) plating for printed circuit boards. Often called the "universal finish," it is designed for high-reliability applications requiring a combination of soldering, wire bonding (gold, aluminum, or copper), and electrical contact surfaces. Key Features of the IPC-4556 Standard ipc4556 pdf

The IPC-4556A standard (June 2025) defines requirements for Electroless Nickel/Electroless Palladium/Immersion Gold (ENEPIG) plating, specifying thickness ranges for solderability and wire bondability, including 3.0–6.0 µm of Nickel and 0.05–0.30 µm of Palladium. This standard ensures reliability for complex PCB assembly by providing a robust barrier against nickel corrosion.
