Ceramic PCBs (Ceramic Printed Circuit Boards) are circuit boards that use ceramic materials as substrates, offering excellent thermal management, electrical performance, and mechanical properties. Based on different application requirements and characteristics, ceramic PCBs come in various types, which are outlined below: Single-Layer Ceramic PCB: These are basic ceramic PCBs with a single conductive layer on the...

With the widespread adoption of new energy vehicles, more people are recognizing the excellent performance of ceramic substrates, and the demand for these materials is steadily increasing. Compared to traditional fiberglass boards, ceramic substrates offer superior mechanical strength, high-temperature resistance, and excellent thermal conductivity. In addition, ceramic substrates also exhibit excellent dimensional and chemical stability. However, they...

In the world of electronics, where technological advancements occur rapidly, the multilayer PCB has established its dominance. Over the past few decades, multilayer printed circuit boards have become an indispensable part of modern electronic devices, enabling them to meet the complex needs of today’s consumers. From Single to Double-sided PCB to Multilayer PCB Traditionally, printed circuit boards...

Multilayer Printed Circuit Boards (PCBs) or Multilayer Boards (MLBs) feature more than two copper layers, interconnected using copper-plated holes. These holes may include NC vias, laser microvias, through-holes, buried, or blind vias. The layers consist of copper foil, prepreg (PP), or adhesive materials and are pressed together under high temperature and pressure. This process removes air...

What’s HDI PCB? High-density interconnect (HDI) PCBs are characterized by finer lines, closer spaces, and more dense wiring, which allow for a faster connection while reducing the size and bulk of a project. These boards also feature blind and buried vias, laser ablated microvias, sequential lamination, and via in-pads. As a result, a HDI board can house the functionality of the previous...

Rigid-Flex boards are a combination of rigid boards and flexible circuits that are permanently laminated together and interconnected through through-holes. Rigid-Flex boards are also written as Flex-Rigid. Rigid-Flex boards straddle the boundaries of traditional rigid boards and the unique properties of flexible circuits, using highly ductile ED or RA copper photolithography onto a flexible insulating film....
