Shanghai Yitong Photonics Technology Co., Ltd. and RX Global have formed a strategic partnership to co-host Photonics World Asia 2024. Held as a preview edition, the show will take place from November 6 to 8, 2024 at the Shenzhen World Exhibition and Convention Center (Bao'an), alongside six RX flagship exhibitions. The event focuses on laser technology and applications, optical systems and precision optics, precision machinery and motion control, and test, measurement and sensing technology. It is expected to attract 10,000 professional visitors from China and abroad, with industry conferences on laser applications in touchscreens, semiconductor manufacturing and other fields.
Guangdong Huoer Laser Technology Co., Ltd. has completed a new financing round worth tens of millions of yuan, with investment from Shenzhen Huixin Investment and Huafeng Capital serving as exclusive financial adviser. The funds will go toward blue-infrared laser welding product R&D, team expansion and market development. The company's 455 nm blue laser boosts copper absorption by 12 times and gold absorption by 60 times compared with 1064 nm near-infrared light. Its blue-infrared hybrid welding solution addresses spatter, porosity and heat-affected zone issues in copper, gold and aluminum welding, improving cycle time, stability and yield for flat-wire motor stator windings and lithium battery copper tabs.
Jiangsu Qunchuang Photovoltaic Technology Co., Ltd. was recently established with registered capital of 160 million yuan. It is jointly held by 11 industry chain companies, including Trina Solar, SC New Energy Technology and Suzhou Yourgood New Material, with Dier Laser holding a 3.1250% stake. The company's business scope includes solar power technology services, manufacturing of photovoltaic equipment and components, and leasing of photovoltaic power generation equipment. Dier Laser holds a global combined market share of over 80% for its core photovoltaic products, and announced earlier this month plans to invest 3 billion yuan in capacity expansion.
A team led by Professor Luo Sida at Beihang University has developed a fabrication method for laser-induced graphene smart honeycombs with designable structures, allowing control of cell size, shape and graphene clusters. The process combines graphene paper, polyurethane film lamination and resin impregnation and curing, producing structures of about 150×100×10 mm3 and honeycombs with cell sizes from 2 mm to 5 mm. The team also explored applications of a wing-section model in anti-icing and de-icing, pressure sensing and electromagnetic shielding.
Why we recommend it: Linking laser processing parameters, honeycomb geometry and resin content to performance control offers a process approach for transferring 2D material processing to customizable 3D structures.
Focuslight addresses Mini and Micro LED process challenges through laser mass transfer, mass welding and chip repair, with key factors being spot control, energy uniformity and closed-loop temperature control. The Flux H system for mass welding uses a 4000-10000W, 976nm light source, with spot length and width adjustable in segments from 2 mm to 200 mm and energy uniformity above 97%. The Flux H system for chip repair uses a 30-150W, 976nm light source, with a 365um×105um spot and energy uniformity above 90%.
Why we recommend it: Mapping mass transfer, welding and repair to spot and thermal management requirements provides a concrete method for working backward from display manufacturing bottlenecks to laser system design parameters.

Suda Weige announced the successful delivery of an independently developed large direct-write lithography system for lithographic manufacturing of materials used in photonic chips, optical communications and optical chips. The system supports real-time 3D navigation autofocus on large-area substrates, proximity effect compensation during exposure and other functions. Several more large lithography system contracts are awaiting delivery. The company also plans to transfer 100% of Huarisheng for 550 million yuan, concentrating resources on micro- and nano-optics equipment and materials.
Why we recommend it: The equipment delivery and the planned exit from the reflective materials business together show a path of concentrating resources in micro- and nano-manufacturing, useful for understanding Suda Weige's technology portfolio and commercialization direction.
