What Is the Dragon Boat Festival and Why Is It Celebrated?   The Dragon Boat Festival, also known as Duanwu Festival, is a traditional Chinese holiday that is celebrated on the 5th day of the 5th month of the lunar calendar, which usually falls in late May or early June in the Gregorian calendar. It is a significant cultural festival in China and is also observed by Chinese communities around the world.   The Dragon Boat Festival has a history of over 2,000 years and is celebrated to commemorate the Chinese poet and statesman Qu Yuan (c. 340–278 BCE). Qu Yuan was a patriotic poet during the Warring States period in ancient China. He was deeply devoted to his country and wrote many poems expressing his love for his homeland.   Legend has it that when Qu Yuan's kingdom was conquered, he drowned himself in a river out of despair. The local people admired Qu Yuan and were distraught over his death. To prevent fish and evil spirits from devouring his body, they beat drums, splashed the water with paddles, and threw sticky rice dumplings (known as zongzi) into the river to feed the fish. They also raced in boats to search for his body. These traditions have been passed down and are still practiced during the Dragon Boat Festival today.   The main activities of the Dragon Boat Festival include dragon boat races, eating zongzi, and hanging up pouches of herbs. Dragon boat races involve teams of rowers paddling in long, narrow boats, decorated like dragons, to the beat of a drum. Zongzi, pyramid-shaped glutinous rice dumplings wrapped in bamboo leaves, are a traditional food eaten during the festival. They can be filled with various ingredients like beans, meat, or nuts. Hanging up pouches of herbs, known as "xiong huang" or "mo xiang," is believed to ward off evil spirits and bring good luck.   Overall, the Dragon Boat Festival is a time for people to pay tribute to Qu Yuan's patriotism, enjoy festive activities, strengthen community bonds, and celebrate Chinese culture and traditions.   Our company will be observing a holiday break from 8th June. to 10th June. 2024 forDragon Boat Festival.   We will back on11th June. We are sorry for any convenience it may occur. Should you have anyinquiries for any high frequency PCBs during our holidays,Please feel free to email to info@bichengpcb.com.

What Are Some Other Challenges That PCB Manufacturers Face When Working with High-Frequency PCBs?   In the rapidly evolving world of electronics, the demand for high-performance, high-frequency printed circuit boards (PCBs) is on the rise. These specialized circuit boards are essential components in a wide range of applications, from high-power RF and microwave amplifiers to advanced radar and military electronics. However, the fabrication of high-frequency PCBs poses unique challenges that PCB manufacturers must overcome to ensure reliability and consistent performance.   One such challenge is the use of specialized materials. The Rogers RT/duroid 6035HTC high-frequency circuit material is a prime example of the advanced materials required for these applications. This ceramic-filled PTFE composite offers exceptional thermal conductivity, nearly 2.4 times that of standard RT/duroid 6000 products, enabling improved heat dissipation and lower operating temperatures for high-power circuits. Additionally, the material's low dielectric constant (3.5 ± 0.05 at 10 GHz/23°C) and low dissipation factor (0.0013 at 10 GHz/23°C) contribute to excellent high-frequency performance, with minimal signal distortion and attenuation.   Alongside material selection, PCB manufacturers must also navigate the intricacies of precise impedance control. Maintaining a consistent, controlled impedance across high-frequency signal paths is crucial to prevent reflections and impedance mismatches that can degrade signal integrity. This requires specialized design techniques, such as careful trace width and spacing calculations, as well as advanced manufacturing processes like uniform copper plating and laser trimming.   PCB manufacturers utilize a variety of specialized techniques and processes to ensure the reliability of high-frequency printed circuit boards in harsh operating environments:   Impedance Control Maintaining precise, consistent impedance along high-speed transmission lines is critical for signal integrity at microwave and millimeter-wave frequencies. Even slight variations in trace width, copper thickness, or dielectric thickness can cause reflection and distortion issues. Specialized impedance control techniques, such as uniform conductor plating and laser trimming, are required.   Crosstalk Mitigation The close trace spacing and high frequencies involved make high-frequency PCBs highly susceptible to crosstalk between adjacent signals. Design strategies like increased trace spacing, shielding planes, and specialized trace routing are necessary to isolate sensitive RF/microwave traces.   Test and Measurement Verifying the performance of high-frequency PCBs requires advanced test equipment and measurement techniques. Traditional benchtop multimeters and scopes are insufficient - PCB manufacturers must utilize vector network analyzers, spectrum analyzers, and other specialized instrumentation capable of operating at m...

Researchers Have Developed New PCB Materials That Can Achieve Over 90% Raw Material Recovery     The University of Washington research and development team recently announced that it has successfully developed a new type of PCB called vPCB.   vPCB is made of Vitrimer-like polymer (Vitrimer) material, which has comparable electrical properties to traditional PCBS, while achieving a raw material recovery rate of over 90%.    The left side is vPCB, the middle is glass fiber layer, and the right side is recycled vitreous polymer material. Photo source University of Washington official website, the samepicturebelow   Traditional PCBS are usually composed of glass fiber reinforced epoxy resin laminates covered with copper foil. After PCB waste, it is difficult to separate the epoxy resin from the glass fiber. This hinders the recycling of PCB materials and increases the difficulty of e-waste reuse.   The team at the University of Washington has successfully developed a vitreous polymer material. The material can replace the epoxy resin in the PCB, and at the same time, it can be converted into a jelly-like substance by a special solvent, which can be separated and recycled from the PCB.    ▲ Vitreous polymer material removed with tweezers   The team claims to have achieved 98% recovery of vitreous polymer, 100% recovery of glass fiber and 91% recovery of solvent.   Less than a decade old, this class of vitreous polymers, first developed in 2015, have "dynamic covalent bonds" that reversibly crack and recombine when exposed to specific environments.   In addition to the ease of recycling, VPCBS using vitreous polymer-like polymers have other unique advantages: due to their reconfigurable properties, VPCBS that bend or crack can be repaired in specific environments.   The University of Washington said in a related article that the production of VPCBS does not require major adjustments to the PCB manufacturing process.
