Obsolescence Management: Securing a Long-Term Supply of Thermal Interface Materials for Legacy Products
For products with multi-decade lifecycles—such as medical imaging systems, industrial controllers, or avionics—a sudden discontinuation of a single component can trigger a costly redesign or jeopardize ongoing service. The thermal interface material (TIM), though small, is no exception. Proactive obsolescence management is essential.
The challenge with TIMs is that their formulations can change or be discontinued as suppliers optimize for high-volume, cutting-edge markets, leaving legacy applications stranded. Here’s a strategic approach:
1. Proactive Partnership from Day One:
During the initial design phase, engage with your TIM supplier not just as a vendor, but as a lifecycle partner. Discuss their product roadmap and policy regarding long-term support for stable formulations. Securing a documented commitment or establishing a lifetime buy agreement upfront can prevent future crises.
2. Building a Qualified Alternate Source List:
Never rely on a single-source TIM. As part of your qualification process, pre-qualify a second-source or drop-in replacement material from a different supplier (like our SP180 series for various industry benchmarks). This involves rigorous testing for thermal performance, reliability, and process compatibility. This validated alternate becomes your insurance policy.
3. Strategic Inventory and Last-Time Buys:
Monitor component life status reports. Upon receiving a product discontinuance notice, execute a calculated last-time buy to build a bridge inventory that supports your product’s service life. For critical products, consider holding a 5-to-10-year strategic stock of key TIMs in controlled storage.
At Thermal Silicon Pad, we understand that reliability extends beyond the device to its supply chain. We offer extended product lifecycle support and stable formulations designed for industries where products are built to last, ensuring your legacy systems remain serviceable and compliant for years to come.
