Shenzhen Kinghelm Secures Chinese Trademark “Kinghelm” in Major Brand Milestone

Image
Recently, Shenzhen Kinghelm Electronics Co., Ltd. successfully registered its Chinese trademark “Kinghelm,” securing exclusive rights to the company name and further strengthening its brand identity ( www.kinghelm.net ). The trademark was officially registered on February 28, 2026, and will remain valid for ten years through February 27, 2036. It is approved under International Class 9, covering semiconductor-related goods and services. The Chinese “Kinghelm” trademark adopts a clean, basic Hei-style font in compliance with the Requirements for Chinese Fonts Usage (2023 Edition). This choice ensures excellent readability across different sizes, viewing distances, and background conditions, while maintaining strong visual recognition. In addition, the use of a widely recognized base font helps avoid potential commercial copyright risks, as such standardized, minimally styled fonts are generally considered public domain and suitable for commercial applications.   Chinese trademark Ki...

SLCE1005A015FR: Ultra-Compact 0603 ESD Protection for High-Frequency Designs

Image
 Slkor introduces the SLCE1005A015FR ESD protection diode, engineered for high-frequency electronic applications. Featuring an ultra-compact 0603 package and ultra-low capacitance, it delivers dependable electrostatic protection for high-speed interfaces such as HDMI 1.3, high-speed Ethernet, and USB 2.0. Designed to suppress electrostatic discharge (ESD) and transient interference, the SLCE1005A015FR helps maintain signal integrity and ensures stable device performance even in demanding electromagnetic environments. The core advantage of this device lies in its precise protection and excellent signal compatibility in high-frequency environments: built with thick-film technology and a bidirectional protection design, it features an ultra-low junction capacitance (Cp) of just 0.15pF (typical), minimizing signal distortion even at 1MHz and making it well suited for high-frequency applications up to 3.4GHz, such as HDMI 1.3 interfaces. Its insertion loss is extremely low — only −0.25d...

From Groundwork to Greatness: The Making of Domestic Semiconductor Capability (Part I)

Image
Friends of the Huaqiang Lecture Hall, it’s a pleasure to reconnect with you. My surname is Song—though some new friends occasionally assume my name is Kinghelm, which is actually the English name of my company. The Huaqiang Lecture Hall has always served as a platform for exchanging ideas, learning, and meaningful dialogue. This is my third time speaking here. During my first session, I shared insights on Kinghelm’s GPS and BeiDou antennas and navigation modules; in the second, I introduced Slkor’s silicon carbide technology. Often jokingly referred to as a “street economist” in Huaqiangbei, I have also experienced the challenges of entrepreneurship firsthand—even selling personal property at times to continue investing in the integrated circuit industry. Today, I would like to draw from those experiences to share my perspective on “The Road to Domestic Semiconductor Development.”   In 2020, as the global pandemic unfolded and strategic competition intensified, integrated circuits...

Back to Wuhan: Wu Junrong’s Journey Through Memory, Heritage, and River Breeze

Image
On the 28th day of the twelfth lunar month, the car entered Wuhan. This was my first return since the pandemic. The city seemed to have shed its old appearance—low houses from memory were largely replaced by glass-curtain high-rises, elevated roads carved a new skyline across the horizon, and the winter air carried a faint mix of fresh paint and blooming plum blossoms. My husband suggested walking from Parrot Island Yangtze River Bridge to the First Yangtze River Bridge. At dusk, the bridge cables stretched across the sky like harp strings. The moist river wind swept over us, carrying the breath of the Yangtze. Across the water, the golden dome of Yellow Crane Tower shimmered in the fading sunset light. As we reached the First Bridge, its red towers, slightly weathered yet dignified, stood like silent witnesses to generations crossing the river. Along the riverbank reeds, children ran past waving sparklers, their laughter breaking the crisp winter air. The lights along both shores cu...
