The Impact of Rising Gold Prices on ENIG PCB Costs

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...

IC Substrate vs PCB: Key Differences and SQPCB Solutions

What is an IC Substrate? IC Substrate (Integrated Circuit Substrate) is primarily used in chip packaging and serves as the “bridge” between the semiconductor chip and the printed circuit board. Chips are extremely small, with pad diameters typically around 0.05 mm, whereas the minimum pad diameter on a standard PCB is usually 0.3 mm or larger. This huge size difference makes it impossible to achie...
