Anyone procuring PCBs for an industrial control system does not automatically think of AI data centres. Nevertheless, both applications can be affected by developments on the same input material markets. The expansion of AI infrastructure is changing which materials are in demand and where manufacturers direct their investments. For electronics companies, this raises a practical question: how resilient is their own material supply when priorities in the supply chain shift?
The influence begins before PCB production
PCBs are made from several materials that are matched to one another. In glass-fabric-reinforced constructions, these include glass fabric, resin systems and copper foils. Among other things, these are used to produce prepregs and copper-clad laminates, which the PCB manufacturer then processes further. The availability of a finished PCB therefore depends on decisions that are taken several production stages earlier.
The Lexington market briefing of August 2026 describes an increasing orientation of material and production capacities towards AI applications. Demanding input materials for high layer counts and fast data transmission are said to be in particular demand. According to this assessment, standard and automotive applications are coming under pressure as a result. This is a market observation tied to a particular point in time: whether a specific project is affected is determined by its material construction and sources of supply.
Why attractive applications tie up capacity
Manufacturers plan their production according to expected demand, technical suitability and economic prospects. How bindingly a customer commits to its requirements also counts. The Lexington documents of June 2026 describe long-term orders and economically attractive conditions as reasons for the orientation towards AI. Binding purchase commitments give manufacturers a more reliable basis for utilisation and investment than non-binding forecasts. Where capacity is scarce, AI orders secured in this way can therefore be given priority.
Automotive projects also have long planning horizons. However, product planning over several years is not automatically a firm purchase agreement for the materials required. If quantities only become binding at short notice or can be adjusted regularly, more uncertainty remains for the material manufacturer. The difference therefore lies in how binding the commitments are and not in the industry alone. It applies where the respective procurement models actually differ.
This can have consequences for other buyers even though their own requirements remain unchanged. A laminate that has so far been regularly available may compete for precursors or machine time with materials that are given higher priority. The decisive point is not solely whether two customers buy exactly the same product. Shared production steps, suppliers and investment budgets can also create a link between different applications.
Different PCBs are affected differently
The term AI does not describe a uniform type of PCB. Nor do industrial or automotive applications form a homogeneous material market. A simple control board, a high-performance communication unit and a high-layer-count server board can have very different requirements. It would therefore be misleading to infer directly from a shortage of speciality copper foil that there is an equally large shortage of all PCBs.
It makes sense to look at material groups. Which glass fabrics are used? Which laminates and prepregs are approved? Are special copper surfaces required? Only this mapping shows whether a project competes directly with applications in strong demand or could rather be affected indirectly by changed capacity decisions. At the same time, it prevents general market reports from triggering unnecessary procurement reactions.
Which information helps now
For purchasing, it is worth looking at delivery dates together with the degree to which they are actually secured. Is the input material already on hand, is it firmly allocated or has it merely been requested? A date confirmation based on available materials carries a different weight from a plan that still rests on several outstanding supplies. This distinction should be visible in project communication.
Development can also contribute to security of supply. If technically suitable alternatives are taken into account at an early stage, there is more room for manoeuvre. The prerequisite is a documented assessment of the relevant properties. A substitution at short notice solely because of better availability can make additional tests necessary and cancel out the supposed time saving. Material selection and procurement strategy should therefore come together as early as the design stage.
An example illustrates the connection: one customer submits an annual forecast but only confirms its purchases shortly before the date of need. Another agrees binding quantities for the same period. For the manufacturer, these orders offer different degrees of planning certainty. Where material is limited, this can influence allocation. Early information is therefore helpful; what remains decisive is which quantities have actually been agreed and how these commitments are passed on to the input material suppliers.
Aligning your own procurement in a targeted way
AI is changing the conditions for PCB procurement at the point where material demand and available capacity meet. For companies, this means above all knowing their own dependencies more precisely. Those who consider critical input materials, approvals and required dates together can translate market developments into concrete decisions instead of reacting to every new shortage report in the same way.
