first_img Ming-Chi Kuo: NVIDIA tests fiberglass-free copper-clad laminates

Tianfeng International Securities analyst Guo Mingqi published that his latest supply chain check shows that NVIDIA has begun testing fiberglass-free copper-clad laminates primarily made of hydrocarbon resin to replace the previously tested fiberglass-free PTFE copper-clad laminates, along with fiberglass-free hydrocarbon prepregs. The test aims to confirm whether this combination can meet the requirements of the Rubin Ultra NVL576 exchange tray PCB. NVL576 is an eight-rack interconnection solution expected to enter mass production in the second half of 2027.Guo Mingqi stated that preliminary tests conducted to enhance PCB manufacturability show that the fiberglass-free hydrocarbon copper-clad laminate has met the high-frequency electrical requirements of the exchange tray. Its electrical performance lags behind the original PTFE solution but is better than the M9 level solution and exceeds the M10 published specifications. This result does not represent the final material selection, indicating that NVIDIA is still seeking higher PCB manufacturing yields and production efficiency while meeting electrical requirements.Guo Mingqi mentioned that Shengyi Technology is currently the leading supplier for the NVL576 exchange tray material evaluation, with related materials including fiberglass-free PTFE copper-clad laminate SG5300N, fiberglass-free hydrocarbon copper-clad laminate SG1030N, and fiberglass-free hydrocarbon prepreg SIF09. SG1030N and SIF09 still contain a small amount of PTFE. He also stated that once specifications are confirmed and mass production begins, Shengyi Technology is expected to accelerate procurement from Chinese hydrocarbon material suppliers such as Dongcai, Shengquan, and potential supplier GCH Technology.

first_img Ethereum Glamsterdam upgrade passed the rehearsal, scheduled to launch Sepolia on October 6

According to CoinDesk, the Ethereum Glamsterdam upgrade has continued to confirm blocks after adopting new block construction rules this week, passing key tests and paving the way for its planned launch on the Sepolia public testnet on October 6. The Nethermind client subsequently completed performance tests involving one of the biggest changes in Glamsterdam, with all 2,302 tests passing, processing 57.07 billion gas in 3 minutes and 15 seconds, averaging about 2.9 billion gas per second.The benchmark measures the speed of the Nethermind execution software rather than the entire network, testing block-level access lists. This mechanism informs Ethereum nodes in advance about which accounts and storage data will be used in the block, allowing nodes to fetch data and check unrelated transactions simultaneously, whereas the current Ethereum mostly processes related work sequentially, limiting the amount of activity each block can accommodate. About an hour after the testnet launch, Glamsterdam raised the block gas limit from 60 million to 200 million, freeing up space for more payments, token swaps, and other activities per block.The 200 million gas limit allows Ethereum to absorb more activity before users start bidding for block space, thereby alleviating fee spikes during transaction surges or when popular tokens are launched. Larger blocks are also harder to verify, which may make it difficult for small-scale operators to keep up. Glamsterdam aims to gain additional capacity without excessively increasing chain operating costs. This upgrade also extends the block data propagation time from about 2 seconds to 9 seconds and plans to incorporate the handover and payment of block construction and verification into Ethereum's own rules, reducing reliance on external relay services.
