Knocking Down the Bone Pile: Addressing End-of-life Component Solderability Issues, Part 4

07/15/2025 | Nash Bell -- Column: Knocking Down the Bone Pile
In 1983, the Department of Defense identified that over 40% of military electronic system failures in the field were electrical, with approximately 50% attributed to poor solder connections. Investigations revealed that plated finishes, typically nickel or tin, were porous and non-intermetallic.

STMicroelectronics, Metalenz Sign a New License Agreement to Accelerate Metasurface Optics Adoption

07/14/2025 | STMicroelectronics
STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications and Metalenz, the pioneer of metasurface optics, announced a new license agreement.

Digital Twin Concept in Copper Electroplating Process Performance

07/11/2025 | Aga Franczak, Robrecht Belis, Elsyca N.V.
PCB manufacturing involves transforming a design into a physical board while meeting specific requirements. Understanding these design specifications is crucial, as they directly impact the PCB's fabrication process, performance, and yield rate. One key design specification is copper thieving—the addition of “dummy” pads across the surface that are plated along with the features designed on the outer layers. The purpose of the process is to provide a uniform distribution of copper across the outer layers to make the plating current density and plating in the holes more uniform.

Global PCB Connections: Embedded Components—The Future of High-performance PCB Design

06/19/2025 | Jerome Larez -- Column: Global PCB Connections
A promising advancement in this space is the integration of embedded components directly within the PCB substrate. Embedded components—such as resistors, capacitors, and even semiconductors—can be placed within the internal layers of the PCB rather than mounted on the surface. This enables designers to maximize available real estate and improve performance, reliability, and manufacturability.

Preventing Surface Prep Defects and Ensuring Reliability

06/10/2025 | Marcy LaRont, PCB007 Magazine
In printed circuit board (PCB) fabrication, surface preparation is a critical process that ensures strong adhesion, reliable plating, and long-term product performance. Without proper surface treatment, manufacturers may encounter defects such as delamination, poor solder mask adhesion, and plating failures. This article examines key surface preparation techniques, common defects resulting from improper processes, and real-world case studies that illustrate best practices.
