What is ENIG-Black Pad? ENIG-Black Pad (BPD), also known as “Black Pad Syndrome”, is a defect that can occur in printed circuit boards (PCBs) with an Electroless Nickel Immersion Gold (ENIG) surface finish. It is characterized by the formation of a thin, brittle layer of black nickel oxide or phosphorous compounds between the nickel and gold layers, leading to poor solderability and weak solder joint strength. BPD has become an increasingly common issue in the Read more…
Introduction to Electroplated Nickel in PCB Manufacturing Electroplated nickel is a crucial process in the manufacturing of printed circuit boards (PCBs). This process involves depositing a thin layer of nickel onto the surface of the PCB through an electrochemical process. The nickel layer serves various purposes, including improving the solderability, enhancing the corrosion resistance, and providing a barrier layer between the copper substrate and the subsequent surface finishes. In this article, we will delve into Read more…
Understanding PCB Surface Finishes A PCB surface finish is a coating applied to the exposed copper traces and pads on a printed circuit board.
