Subtitle: Accurate Calculation of Raw Material Cost Increase for Double-Sided ENIG PCBs Post-September 2025 – Help You Judge If Supplier's Price Hike Is Reasonable Introduction (Address Pain Points Directly) Post-September 2025, the collective raw material price surge in the PCB industry has troubled many electronic manufacturers and procurement professionals: suppliers of double-sided ENIG (Elect...

In the electronics manufacturing industry, Electroless Nickel Immersion Gold (ENIG) is a premium surface finish for printed circuit boards (PCBs), valued for its exceptional solderability, corrosion resistance, and signal stability. As global gold prices remain at a historical high in 2026, ENIG costs have become a critical factor in PCB manufacturers’ cost-control strategies. This article provide...

The Impact of Rising Gold Prices on ENIG PCB Costs ENIG PCB (Electroless Nickel Immersion Gold PCB) is one of the most widely used finishes. The ENIG process deposits a thin layer of nickel on the copper surface, followed by a very thin layer of gold. This protects the copper from oxidation, enhances solderability, and extends the PCB’s lifespan. SQPCB is a professional ENIG PCB manufacturer, serv...

Flash Gold, ENIG, and Gold Plating In the world of PCB manufacturing, the choice of surface finish plays a crucial role in ensuring the quality, durability, and performance of the final product. Gold finishes, including flash gold, ENIG (Electroless Nickel Immersion Gold), and gold plating, are commonly used to protect the copper traces and pads on the PCB from oxidation, improve solderability, an...

Introduction OF ENIG In the PCB manufacturing process, surface treatment plays a crucial role, directly affecting the solderability, electrical performance, durability, and overall reliability of the circuit board. Surface treatment not only protects the PCB from oxidation, corrosion, and environmental factors but also ensures smooth soldering processes. This is particularly important for high-per...
