Citing sources from motherboard makers, news and rumor site DigiTimes says there's a shortage of mobo components , including multilayered ceramic chips (MLCCs), solid capacitors, LAN connectors, and other odds and ends. The reason, sources say, is because of recent labor shortages.
In response to the shortages, Asus, Gigabyte, MSI, and ECS have all begun "aggressively placing orders" in an attempt to avoid having the component shortages affect overall shipments.
The good news is that the labor situation is expected to improve after April, by which time the mobo market will have entered the slow season. The tight supply of components will also improve, but component makers fear that their performance will be affected in the second quarter as top-tier mobo makers halt any new orders to avoid a surplus in inventory.
