Ceramic circuit boards, benefiting from their inherent material advantages, have become a core choice for high-end applications. Among the various manufacturing approaches, the DPC (Direct Plated Copper) process has

As electronic equipment continues to demand higher power density and greater operational stability, ceramic circuit boards have seen increasing adoption in high-end manufacturing sectors due to their excellent thermal conductivity, high dielectric strength, and superior resistance to high temperatures. Compared with conventional FR-4 PCBs, ceramic circuit boards are generally much more expensive. This price gap

As radio-frequency communications, millimetre-wave radar, high-speed interconnects and power modules advance towards higher frequencies, the transmission characteristics of signals within printed circuit boards undergo fundamental changes. Under high-frequency conditions, energy dissipation ceases to be governed by a single dominant factor, instead being determined by the combined effects of material polarisation behaviour, conductor current distribution and

In the manufacturing process of multilayer ceramic pcb, lamination is not merely a straightforward step of ‘stacking and applying pressure’. As the number of layers increases, circuit density rises, and substrate dimensions expand, the differing responses of each layer’s materials under stress and thermal conditions become progressively amplified.
