Wisdom connect know of APP of finance and economics, fair cloth studies the report says in, AI large model develops quickly, drive of hopeful of new investment demand calculates growth of force index level. Between processor and processor, the data between processor and memory is alternant more will frequent, also raise taller requirement to receiving a transmission rate. Inside the server board on communication technology is greeted large-scale upgrade, this will drive interface communication chip, enclose the norms such as technology and PCB material to promote considerably, bring new market opportunity.
In gold is main the viewpoint is as follows:
PCIe bus line upgrades continuously, NVlInk leads a server in-house communication new change.
PCIe upgrades 3 every years on average generation standard, at present the market appears much for generations to coexist situation, should think in high-powered server demand adds a trend high to fall all right, CPU iteration hopeful quickens PCIe 5.0 wholesale business to use process; at the same time, PCIe Retimer and Switch chip produce main effect in access of high speed PCIe, market space but period. In setting of calculation of AI different form, the abidance that calculates force increases to depend on sheet not only piece the function promotion that GPU blocks, still need many calories of efficient group, NVlInk becomes the crucial channel that realizes interconnection of the high speed between much GPU, introduce be based on NVlThe NVSwitch chip that compose of ability of Ink advanced communication builds in order to solve problem of disequilibrium of the communication between GPU, make group of GPU of much node of complete bandwidth connective then.
Advanced enclose a technology to be entered ceaselessly rank, boom of ABF support plate promotes.
Plan of compose of numerous nucleus different is driven advanced enclose a technology to gradual progress of taller join density, the whole world is advanced enclose demand to present growth state, among them Fan-out, 2.5D/3D encloses the market to add fast get run industry. From advanced enclose material to look, what should think ABF support plate regards the expensive operation function such as CPU, GPU as chip all right is important bear the weight of, what AI tide brings hopeful benefit from benefit from is tall; of increase sharply of demand of chip calculating force at the same time, chiplet different compose is compositive below naked piece join demand increases, area of ABF support plate increases, and because fine rate falls and support plate wastage increases, demand of advanced support plate is further up.
PCB high speed is changed drive plank to upgrade, hopeful of upriver colophony material to PPO switch.
Platform of profit from server lasts iteration, overlay with more the AI server demand that high-end PCB is carrier calculating force is rising, more than 16 when should think to be made by M6 and material of above Fu copperplate all right PCB hopeful is permeated quickly in server market, PCB board hopeful greets the Qi Sheng that estimate value. Material of colophony of upper reaches of focusing Fu copperplate, should value all right get together benzene aether (the superior electrochemistry performance after PPO) depends on modified (stability of loss of low interpose report, tall treatment, hear resistance) replace traditional colophony stage by stage, in copperplate of growth of demand of server of downstream high end, Fu high frequency high speed changes the drive of development to fall, space of growth of modified PPO market is vast.
Risk clew: The risk that progress of AI commerce be born anticipates not as good as, cloud firm considers force relevant capital spending anticipates not as good as.
