7 Multiple Manufacturing Sites

To allow for manufacturing flexibility, a COTS product might be produced in several different wafer fabs. Each wafer fab can have slightly different equipment and processes. The difference in the wafer fabs would not impact a product’s performance as long as the product is used within the parameters of the data sheet. These differences could impact how the part performs when operated outside rated parameters and could significantly impact the product’s radiation performance.

Likewise, a COTS or automotive product could be assembled at multiple assembly sites, which could use different mold compounds and bond wires. As described earlier, these differences could have significant impact in product reliability when using the part in a harsh environment beyond the rated performance. Normally, a customer is not able to choose which manufacturing sites are used.

For the TI Space EP products, there is only one production flow, one wafer fab and one assembly site used for each product. This greatly reduces lot-to-lot variations.
