Surface finishes of printed circuit boards - complete guide

PCB surface finishes is essential for best performance, reliability and board life. It protects the copper on the board from oxidation and ensures a reliable connection between the components and the board. Among other things, it also affects the manufacturing process, including the quality of soldering and assembly. Let's talk together about circuit board coatings.

Printed Circuit Boards for the Automotive Industry

Modern vehicles are increasingly reliant on control units. While a moderately equipped car manufactured after 1980 contained around 20 control units, today's vehicles typically have more than 200. Due to this trend, modern vehicles are becoming more dependent on printed circuit boards (PCBs). As PCBs serve as the nervous system of modern cars, it is essential to adhere to safety standards. It is anticipated that with further technological advancements, the demand for PCBs in the automotive industry will continue to grow. In this article, we will discuss the requirements for automotive PCBs, outline the standards for automotive PCBs, and explain why it is beneficial to use AS9100D-certified PCBs in the automotive industry.

Thermal Vias: Maximizing Efficiency in PCB Design

Printed circuit boards (PCBs) commonly feature components that generate more heat than desirable. Typically, copper pads are placed under these components, with vias inserted underneath. These vias are called “thermal vias.” The primary function of these vias is to dissipate heat from the copper pad, thereby helping to regulate the component's temperature.

Microvias in printed circuit boards

In the current technological world, "microvia holes" in printed circuit boards (PCBs) represent a revolutionary approach to manufacturing. By integrating these holes, whether through mechanical or laser drilling, it has been possible to achieve high-density interconnections (HDI) and create designs that were previously deemed impossible with traditional drilling methods. However, despite their enormous potential, concerns about their long-term reliability persist, making them the subject of intensive research.
