The 29th Beijing Science and Technology Week opened at the Central Green Forest Park in Tongzhou, Beijing's sub-center, on May 20, 2023, showcasing nearly 300 exhibits. 

The event will continue until May 31, with the presence of high-tech products from several companies in Beijing E-Town on display.

In the commercial aerospace exhibition area, models of privately developed carrier rockets, such as CERES-1, PALLAS-1, and Zhuque-2 Y-2, were neatly lined up.

Galaxy Power Aerospace, a Chinese private aerospace company from Beijing E-Town, presented its core product models - the CERES series of solid-propellant carrier rockets and the PALLAS series of reusable liquid-propellant carrier rockets.

After years of cultivation, the aerospace industry in Beijing E-Town Development Area has shown a trend of clustered development. 

The aerospace companies in the area cover various aspects of the industry chain, including rocket design, manufacturing, operation, and application, and form a relatively complete commercial aerospace industry system.

Oriental Yuhong, a key high-tech new materials company, participated in the main exhibition of Beijing Science and Technology Week. 

Around the themes of special functional waterproof materials, major infrastructure and civil service solutions, Oriental Yuhong showed off its innovative applications, including the HDPE pre-laid anti-adhesive mountain tunnel waterproof system, railway bridge waterproof system and application, and its single-layer roof TPO waterproof system.

Over the years, the company has developed and launched such innovative and efficient systems as the BIPV roof system, the HEEC near-zero energy consumption building smart platform, the thin plaster exterior wall insulation system, and the "Hongtan" visualization system, as well as several innovative green building materials and environmentally friendly application technologies, according to the head of Oriental Yuhong.

"This is our self-developed power semiconductor analysis instrument, and the first semiconductor test system in China with fast pulse capability and wide voltage/current measurement capability," said a staff member of Ponovo Power, pointing to a black square-shaped device in the middle of the booth.

This PST6747A semiconductor test system was independently developed by Ponovo Power, an enterprise in Beijing E-Town. 

The system enables static full-parameter testing of mainstream power devices, such as IGBT, MOSFET, GTO, and third-generation power semiconductor devices such as GaN and SiC.

This product is comparable to similar international products and is a power semiconductor testing device with fast pulse capability, wide voltage range, and fA-level current detection resolution. It has been applied in various fields, such as industrial enterprises, research institutes, and universities.
