Meaning
Duration between placing an order for integrated circuits and receiving them from the semiconductor manufacturer when supply is rationed due to high demand. For product designers, silicon allocation lead time dictates the development and release schedule of new hardware assemblies. This period begins when the purchase order is confirmed and ends when the wafers or packaged chips are delivered to the assembly plant.
Schedule Delay
Component shortages can push production schedules out by months. When the silicon allocation lead time increases, it forces companies to redesign boards to use alternative chips. This redesign requires additional testing.
Forecasting Strategy
Accurate demand planning is essential for securing a stable supply of critical chips during market shortages. To manage the silicon allocation lead time, procurement teams must share long-term production forecasts with their semiconductor suppliers and place orders far in advance. This commitment ensures that the supplier allocates the necessary manufacturing capacity to meet the company’s future needs.
Alternative Sourcing
Brokers and secondary distributors can sometimes provide chips when the primary manufacturer has none available. However, sourcing through these channels exposes the company to higher prices and the risk of counterfeit parts. If the silicon allocation lead time cannot be resolved through official channels, the engineering team must qualify these secondary parts before they can be used on the production line.
This qualification includes running functional tests and verifying the physical package dimensions to ensure the parts are genuine and will fit the existing board layout.
