Looking at the impact of AI server development on the PCB industry, mainstream AI servers, compared to general servers, incorporate 4 to 8 GPUs. Due to the need for high-frequency and high-speed data transmission, the number of PCB layers increases, and there’s an upgrade in the adoption of CCL grade as well. This surge in GPU integration drives the AI server PCB output value to surpass that of general servers by several times. However, this advancement also brings about higher technological barriers, presenting an opportunity for high-tech PCB manufacturers to benefit.

TrendForce’s perspective: 

• The increased value of AI server PCBs primarily comes from GPU boards.

Taking the NVIDIA DGX A100 as an example, its PCB can be divided into CPU boards, GPU boards, and accessory boards. The overall value of the PCB is about 5 to 6 times higher than that of a general server, with approximately 94% of the incremental value attributed to the GPU boards. This is mainly due to the fact that general servers typically do not include GPUs, while the NVIDIA DGX A100 is equipped with 8 GPUs.

Further analysis reveals that CPU boards, which consist of CPU boards, CPU mainboards, and functional accessory boards, make up about 20% of the overall AI server PCB value. On the other hand, GPU boards, including GPU boards, NV Switch, OAM (OCP Accelerator Module), and UBB (Unit Baseboard), account for around 79% of the total AI server PCB value. Accessory boards, composed of components such as power supplies, HDD, and cooling systems, contribute to only about 1% of the overall AI server PCB value.

• The technological barriers of AI servers are rising, leading to a decrease in the number of suppliers.

Since AI servers require multiple card interconnections with more extensive and denser wiring compared to general servers, and AI GPUs have more pins and an increased number of memory chips, GPU board assemblies may reach 20 layers or more. With the increase in the number of layers, the yield rate decreases.

Additionally, due to the demand for high-frequency and high-speed transmission, CCL materials have evolved from Low Loss grade to Ultra Low Loss grade. As the technological barriers rise, the number of manufacturers capable of entering the AI server supply chain also decreases.

Currently, the suppliers for CPU boards in AI servers include Ibiden, AT&S, Shinko, and Unimicron, while the mainboard PCB suppliers consist of GCE and Tripod. For GPU boards, Ibiden serves as the supplier, and for OAM PCBs, Unimicron and Zhending are the suppliers, with GCE, ACCL, and Tripod currently undergoing certification. The CCL suppliers include EMC. For UBB PCBs, the suppliers are GCE, WUS, and ACCL, with TUC and Panasonic being the CCL suppliers.

Regarding ABF boards, Taiwanese manufacturers have not yet obtained orders for NVIDIA AI GPUs. The main reason for this is the limited production volume of NVIDIA AI GPUs, with an estimated output of only about 1.5 million units in 2023. Additionally, Ibiden’s yield rate for ABF boards with 16 layers or more is approximately 10% to 20% higher than that of Taiwanese manufacturers. However, with TSMC’s continuous expansion of CoWoS capacity, it is expected that the production volume of NVIDIA AI GPUs will reach over 2.7 million units in 2024, and Taiwanese ABF board manufacturers are likely to gain a low single-digit percentage market share.

Samsung Electronics has disclosed its financial results for 2Q23, reporting quarterly revenue of 60.01 trillion Korean won. Although the DS division saw a rebound in revenue, the fall in smartphone shipments led to a 22% YoY decline.

Samsung highlighted an upturn in its memory business in Q2 due to a concentrated focus on HBM and DDR5 products. The company anticipates strong demand in AI applications, which has helped their DRAM shipments surpass expectations. In terms of panel production, earnings from smartphone panels paralleled those of the first quarter, largely owing to the sales of high-end panels. Meanwhile, the production of large panels continues to target the high-end QD-OLED market.

On the foundry side, Samsung reported a quarterly revenue increase during the second quarter, which was bolstered by growing sales to certain American clients. Yet, fab expansion and uncertainty in short-term demand contributed to a reduction in the utilization rate, triggering a substantial decrease in operating profit. The smartphone division experienced a drop in market demand, influenced by macroeconomic conditions such as high interest rates and inflation.

TrendForce reports that Samsung projects a rebound in global demand during 2H23, which could boost their earnings. Although potential macroeconomic risks are on the horizon, they aim to sustain profitability through sales of high-value products and the launch of innovative new products. However, considering the uncertainties for demand, TrendForce cautions that recovery in demand is expected to be gradual, with commodities prices only improving if suppliers maintain ongoing production cuts.

As the mass production of the new iPhone draws near, TrendForce, in April this year, raised concerns in the smartphone industry about several design changes made to the 2023 iPhone models almost half a year ahead of production. The industry is closely monitoring whether related components can keep up with the production schedule to ensure smooth execution of subsequent assembly plans. Recently, TrendForce provided updates on the production progress and details of these components.

According to TrendForce’s investigation, two critical components in the iPhone supply chain are causing worries about potential supply issues – the CIS (CMOS Image Sensor) and the titanium alloy frame. Currently, there are still bottlenecks in the production of these components that need to be overcome.

Regarding the CIS, the bottleneck arises from Sony’s supply of the new 48MP CIS, which is expected to be used in iPhone 15 and iPhone 15 Plus. This CIS adopts a new stacked design, separating the CIS photodiodes and peripheral transistors into three layers instead of the previous double-layer structure. This poses a significant challenge to yield rates, and despite Sony’s efforts to increase production capacity to cope with the yield ramp-up difficulties, the supply situation does not meet anticipated levels, affecting the initial production schedule of the entire device.

As for the titanium frame, due to the elimination of the pressure-sensitive button structure and the slight adjustment in the opening for the mute switch, the suppliers need to re-allocate, set up, and verify the basic operating time of the production lines.

Additionally, the processing procedures for titanium are more complicated compared to stainless steel, which leads to longer production lead times. TrendForce confirmed recently that the titanium frame for the new iPhone is currently one of the components with lower yield rates and supply stability. Therefore, suppliers have expanded production capacity by 20-30% and are working diligently to ensure that even if the initial supply is tight during the early stages of production, they can respond accordingly, ensuring that the launch and supply of the entire device will not be affected.

Given the supply constraints of these two components mentioned above, TrendForce believes that Apple may increase the production proportion of the two Pro models in 3Q23 to fill the gap caused by the initial iPhone 15’s production capacity shortage. This adjustment, in an optimistic scenario, will only involve shifting production proportions between different models in two quarters, with no impact on the annual shipment performance. TrendForce assesses that this possibility is more likely under the current circumstances.

However, if the CIS yield bottleneck is difficult to overcome, it could lead to a substantial reduction in the shipment volume of the 2023 iPhone models. TrendForce will continue to monitor the situation closely.

According to research conducted by TrendForce, the much-anticipated Micro LED version of the Apple Watch is facing yet another delay and is now expected to be launched in the first quarter of 2026. The primary reason behind this delay is believed to be the need for reconfiguring the production supply chain.

Previously, industry speculations suggested that Apple would take charge of the core production process, particularly the massive transfer of Micro LED technology. However, recent industry research by TrendForce indicate that LG Display (LGD) might now take over this crucial aspect of the production process.

The critical process involved in the production of the Micro LED version of the Apple Watch, especially the massive transfer of Micro LED technology, has been a point of interest in the industry. It was widely speculated that Apple would handle this key engineering either at its Cupertino headquarters in the United States or potentially transfer the production to its facility in Longtan, Taiwan, for the essential massive transfer of the technology.

TrendForce understands that Apple’s decision to undertake the crucial engineering process in either the United States or Taiwan reflects their intent to have complete control over the core manufacturing process during the initial production phase. However, this approach also introduces complexities in terms of logistics and supply chain management, as the chips are set to be manufactured in Malaysia, the backplates in South Korea, and the final assembly by system integrators in China or Vietnam.

As a result, recent industry research by TrendForce indicate that Apple has finalized LGD as its primary collaborator for Micro LED production. This means that LGD will now be responsible for the critical massive transfer process. In addition to providing its own equipment and technical support, Apple is also expected to invest in LGD’s related equipment procurement to ensure a smooth transition and expedited progress in the Micro LED production pipeline.

For more information and details about the Micro LED industry, TrendForce will hold the “2023 LED Forum” on September 5th (Tuesday) from 9:30 am to 5:00 pm at the NTUH International Convention Center. The seminar has invited TrendForce’s Senior Research Vice President, Eric Chiou, as well as representatives from various industries such as Mojo Vision, ITRI, Lumus, Unikorn, Porotech, Nitride Semiconductor, Tohoku University, Coherent, InZiv, AUO, and Tianma to share the progress and related applications of Micro LED technology.

TrendForce reported that TV panel purchases are gaining momentum in the early July, with both Chinese and other major brand customers increasing their orders in preparation for the busy promotional season in the second half of the year. Overall, the purchasing momentum is expected to grow by 7-8% in the quarter. The demand-driven growth, coupled with balanced supply and demand, is likely to sustain the upward trend in TV panel prices. For July, prices are projected to rise by $2 for 32-inch panels, $3 for 43-inch panels, $6 for 50-inch and 55-inch panels, $7 for 65-inch panels, and $8 for 75-inch panels.

Meanwhile, MNT panel prices have experienced slight increases, but the market demand for commercial models remains weak compared to consumer models. Consequently, the price hikes are expected to be modest, and various panel manufacturers are implementing different pricing strategies for different customers and sizes. For July, MNT panel Open Cell prices are expected to rise by approximately $0.2 to $0.5, while 21.5-inch module prices will increase by $0.2 and 23.8-inch module prices by $0.1. Prices for 27-inch modules will remain stable.

As for NB panel prices, after a stable period, panel manufacturers are contemplating raising prices in the third quarter. However, brand customers remain cautious about the demand for the second half of the year, resulting in ongoing negotiations with panel manufacturers. The demand for lower-end TN models is stronger than for higher-end IPS models, leading brand customers to tend to accept slight increases in TN panel prices. For July, mainstream sizes like 14-inch and 15.6-inch TN models are expected to see a minor increase of $0.1, while prices for IPS models will remain stable.
