Shenzhen KKPCB Technology Co., Ltd. is a company that specializes in the design, manufacture, and assembly of various printed circuit boards (PCBs), including ceramic substrates.
NIKKO LTCC substrates with silver conductor material provide multilayer substrates with low dielectric loss. Coils, capacitors and resistors can be embedded in the inner layer. Ideal for high-frequency modules and silicon wafer interposer substrates
The thermal expansion coefficient of these LTCC substrates is adjusted for use as wafer-level packaging substrates. The substrate surface has bumps for electrical connections, and CSP (chip-scale package) can be easily assembled by directly bonding to silicon wafers. Ideal for MEMS and semiconductor ceramic packages with a small number of leads.

LTCC (Low Temperature Co-fired Ceramic) is a special type of ceramic material that integrates multiple ceramic layers together through a co-firing process. With its unique performance advantages, LTCC has found widespread application in circuits and systems operating at microwave, millimeter-wave, and higher frequencies.
With the rapid development of high-speed circuit design, PCB routing has evolved beyond simple interconnection tasks. Engineers must analyze various distributed parameters using transmission line theory. Distributed parameter circuits account for spatial variations in voltage and current. Modern PCBs, with their complexity and density, include advanced features like microvias, buried/blind vias, and embedded components (e.g., resistors, capacitors). These advancements require PCB designers to understand production processes deeply and adapt their designs to manufacturing constraints.
PCB design requires understanding physical processes and careful organization of layers, power networks, and signal paths. Following these recommendations reduces noise risk, improves reliability, and simplifies the routing of complex systems
When designing high-speed PCBs, the layer stack-up plays a crucial role in ensuring signal integrity, minimizing crosstalk, and achieving optimal electromagnetic compatibility (EMC). For a standard six-layer board with a thickness of 1.6mm, selecting the right structure can significantly impact performance. Below is an analysis of common six-layer board structures and their suitability for high-speed designs
Impedance line routing in multi-layer PCBs is both an art and a science. Adhering to the principles of short lines, symmetry, equal length, and precise compensation ensures high-speed data transmission and robust device performance. By leveraging tools like the Polar Si9000 and applying best practices in design, engineers can effectively address challenges in modern PCB impedance routing.
Closely spaced vias are a common design challenge in multi-layer and high-speed PCB boards. Understanding the implications of tight spacing—such as drilling process inefficiencies, reduced solder ring size, and long-term reliability concerns—is essential. By adhering to recommended spacing guidelines, optimizing via placement, and collaborating with manufacturers, designers can enhance production yield, reduce costs, and ensure robust product per
