Newsroom
Global component shortages are putting embedded projects under pressure. As a leading global System on Modules (SoMs) developer and manufacturer, we keep our customers’ development timelines on track by applying a supply chain strategy built on buffered inventories, in-house production, established relationships with multiple suppliers, and more than two decades of operational experience.
As AI-driven demand accelerated through 2025, memory chip shortages developed as semiconductor manufacturers shifted capacity to large-volume buyers, leaving many sectors, including medical, industrial, edge/IoT, and robotics poorly served. Climbing prices and lengthening lead times, exacerbated by knock-on effects across other SoM components, have created two clear pressure points. SoM vendors relying on outsourced manufacturing have limited flexibility when availability drops, leaving customers facing the same delays. Separately, product developers who chose chip-down architectures over SoM-based designs must procure components on their own. Those buying in smaller quantities are routinely pushed down supplier priority lists, and in many cases cannot get supply at all.
